South Korea IBD surgery budget guide
Planning a bowel-resection bill for Crohn disease or ulcerative colitis
Inflammatory bowel disease surgery does not have one reliable nationwide retail price.
The bill can change with the diseased bowel segment, the length removed, an anastomosis or stoma, open or minimally invasive access, treatment of a fistula or abscess, postoperative complications, nutrition support, hospital type, and the number of planned operations.
A person with Crohn disease discussing a short small-bowel resection therefore has a different budget problem from a person with ulcerative colitis discussing a staged restorative proctocolectomy and ileal pouch-anal anastomosis.
The detailed Korean calculator starts with the hospital’s itemised estimate instead of inventing an average operation price.
It separates covered charges, non-covered charges, post-discharge medical payments, stoma supplies, caregiver and transport costs, income interruption, insurer-confirmed payment, and the incremental Korean medical-expense tax credit.
It also compares a 10% registered special-case patient share with an ordinary 20% inpatient planning scenario for the covered amount entered by the user.
This is a financial planning tool, not a clinical decision aid.
It cannot decide whether an operation is indicated, how much bowel should be preserved, whether a strictureplasty is possible, whether a pouch or permanent ileostomy is appropriate, how many stages are safest, or when work should resume.
Those decisions require the treating colorectal or gastrointestinal surgical team and the patient’s full clinical record.
The KRW 8,000,000 covered-charge starting value is hypothetical
The Korean calculator opens with KRW 8,000,000 as an editable covered hospital-charge example.
It is not an official fee, a national average, a median, a minimum, a maximum, or a recommended price.
Replace it with the covered total on the hospital estimate, and enter non-covered lines separately before using the result for a savings or financing decision.
What the calculator separates
Covered hospital charges
Enter the covered charge total to which one patient-share assumption can reasonably be applied.
The tool calculates the patient payment and a planning NHIS share from that total.
Meals, outpatient care, selective benefits, fully patient-paid items, and other separately rated lines should not be mixed into this amount without checking the itemised quote.
Non-covered hospital charges
Enter charges that the provider identifies as non-covered, including any separately quoted robotic access, private-room difference, optional material, or other non-covered item.
A procedure name does not establish the benefit status of every line in the admission.
Use the hospital’s written classification instead of guessing from the word laparoscopic, robotic, pouch, or stoma.
Post-discharge medical payments
Include expected patient payments for follow-up visits, laboratory tests, imaging, endoscopy, wound or stoma care, prescriptions, nutrition care, and other medical-institution spending after discharge.
Crohn disease can require continuing medication and recurrence surveillance even after the diseased segment is removed.
Ulcerative colitis pouch or stoma follow-up can likewise create costs beyond the first admission.
Stoma and household recovery costs
Multiply the expected months of stoma use by the monthly out-of-pocket supply budget after any confirmed support.
Add caregiver and transport costs, then multiply recovery-planning weeks by the net weekly income gap after paid leave or benefits.
These amounts matter to cash flow but are kept outside the medical-expense tax-credit base in the calculator.
Confirmed private-insurance payment
Enter only a payment that the insurer has confirmed or that the household is willing to use as a conservative planning assumption.
The calculation caps the deduction at medical out-of-pocket spending.
It does not use a large insurance entry to erase stoma supplies, transport, caregiver spending, or lost income.
Incremental medical-expense tax credit
The tool compares the annual Korean medical-expense credit base before and after this surgical episode.
It uses the gross salary × 3% threshold and the statutory × 15% credit rate, while removing insurer-reimbursed medical spending.
The result is a planning estimate and not a promise of cash refund because final tax, eligibility, dependant status, documentation, and tax liability still matter.
Crohn disease paths used to organise a quote
Crohn disease can affect discontinuous portions of the gastrointestinal tract and can recur after surgery.
The procedure choice in this calculator changes the consultation checklist and procedure-code anchors only.
It never turns a diagnosis, symptom list, imaging finding, or reported stricture into an automatic surgical recommendation.
Small-bowel resection
This path is for discussion of a diseased small-bowel segment, often in a plan involving obstruction, a fistula, an abscess, or another complication assessed by the clinical team.
Q2650 is used as a consultation anchor for small-bowel resection without lymph-node dissection in the HIRA procedure material.
Ask how much bowel is expected to be removed, whether one or more anastomoses are planned, and whether fistula or abscess treatment appears as a separate line.
Bowel preservation matters because repeated or extensive resection can reduce remaining absorptive length.
The Korea Disease Control and Prevention Agency explains that Crohn surgery is not a cure and that the diseased segment should generally be kept as limited as clinically possible, with strictureplasty considered in appropriate circumstances.
Only the treating team can decide whether that description applies to one patient.
Ileocecal resection
An ileocecal plan can involve terminal ileum and adjacent colon, so small-bowel and colon procedure identifiers may both appear in the discussion.
Q2650, Q2671, and Q2673 are included as possible consultation anchors, not as a guaranteed billing combination.
Ask the hospital to identify the exact small-bowel and colon portions, the anastomosis, pathology, anesthesia, admission, and any separate treatment for a fistula or abscess.
Confirm whether the written estimate covers the whole proposed episode or only the main operative fee.
Preoperative imaging, bowel preparation, nutrition therapy, pathology, a longer admission, and early follow-up can sit outside a headline surgery amount.
Enter patient payments that are not already in the quote under post-discharge or additional medical spending rather than applying the special-case rate twice.
Colon resection
The extent may be partial, subtotal, or total depending on disease distribution and the clinical plan.
Q2671, Q2672, and Q2673 are anchors for discussing hemicolectomy, total colectomy, and partial colectomy categories without lymph-node dissection.
They do not determine whether an anastomosis, temporary diversion, permanent stoma, or simultaneous small-bowel procedure is needed.
Request a stage-by-stage explanation if an initial resection and later stoma reversal are both possible.
Record whether the quote includes one admission, all planned admissions, or only the next operation.
The same scope must then be used for covered, non-covered, follow-up, and household-cost inputs.
Reoperation or complex multi-segment surgery
A previous resection, anastomosis, or stoma can make the new budget more complex.
Adhesiolysis, several diseased segments, fistula repair, abscess management, stoma creation or revision, and a longer nutritional plan can add distinct charge lines.
The calculator keeps the quote editable because a label such as revision or complex surgery is not a price.
Ask which contingencies are already in the estimate and which would be added only if found during the operation.
A variation reserve can help with cash planning, but it is not a prediction of complications.
Clinical risks and alternatives must be discussed with the surgeon rather than inferred from the high and low budget range.
Ulcerative colitis paths and staged surgery
Ulcerative colitis surgery may remove the colon alone at an initial stage or remove the colon and rectum as part of a permanent-ileostomy or restorative-pouch plan.
The safest sequence depends on disease severity, medicines, nutrition, infection risk, urgent presentation, anatomy, fertility considerations, continence goals, and many other clinical factors.
The calculator therefore accepts one, two, or three planned admissions as descriptive information and never recommends the number of stages.
Subtotal colectomy and temporary ileostomy
Q1262 is the consultation anchor for subtotal colectomy without lymph-node dissection.
This can be discussed as an initial operation that leaves the rectum for later management and creates an ileostomy.
Ask whether later proctectomy, pouch creation, and ileostomy reversal are outside the current quote.
Total proctocolectomy with end ileostomy
Q2925 is the anchor for total colon and rectum resection with ileostomy without lymph-node dissection.
The household budget should include stoma education, initial products, recurring supplies, travel for follow-up, and the time needed to develop a stable routine.
Support and out-of-pocket amounts must be confirmed locally rather than assumed.
Restorative proctocolectomy and IPAA
Q2926 is the anchor for total colon and rectum resection with ileal pouch-anal anastomosis without lymph-node dissection.
A restorative plan can be divided across two or three operations and may use a temporary diverting ileostomy.
Obtain separate estimates for pouch creation, stoma creation, stoma reversal, and each admission.
Stage count is not a price multiplier
Suppose a hospital provides a single estimate that already totals all three planned admissions.
Enter that total once and select three stages only to change the explanatory result and checklist.
The dedicated calculation deliberately does not multiply the quote by three.
If the estimate covers only the next admission, enter only that admission and use the same limited scope for all related inputs.
A useful household worksheet can also run the calculator once for each stage and once for the full plan, but each run must avoid counting the same charge twice.
Save the date and scope beside every estimate because plans can change between admissions.
The 2026 Korean special-case rules used by the planner
National Health Insurance Act Enforcement Decree
Article 19 and Annex 2 of the current Enforcement Decree provide the patient cost-sharing framework.
The current law record checked through the National Law Information OPEN API is MST 283469 and took effect on February 19, 2026.
The ordinary inpatient planning comparison in this tool is 20% of the relevant covered amount, while meals and multiple special categories follow separate rules.
The 20% figure is not applied to the non-covered input.
It is also not a substitute for the hospital’s item-level determination when outpatient services, selective benefits, full patient payment, Medical Aid, occupational injury, automobile insurance, or another payer rule applies.
The editable custom rate exists for a documented quote that does not fit either simplified comparison.
Special-case Notice No. 2026-101
The current administrative rule is the Standards for Calculating Special-Case Patient Cost Sharing, Ministry of Health and Welfare Notice No. 2026-101, effective May 1, 2026.
Article 5 provides a 10% patient share for covered care within the registered rare-disease or severe-intractable-disease special case.
The relevant registration period is generally five years, subject to the current rule and the person’s registration status.
Qualifying Crohn disease diagnoses K50.0, K50.1, and K50.8 appear with special-case code V130.
Qualifying ulcerative colitis diagnoses K51.0, K51.2, K51.5, K51.8, and K51.9 appear with V131.
The calculator displays V130 or V131 as a verification prompt, but it cannot look up registration, determine whether the current encounter is within the registered condition, or approve a claim.
Why 10% must not be applied to the whole invoice
The administrative rule does not turn non-covered charges into covered charges.
Separately designated full patient-payment items, selective benefits, non-covered services, meals, and services outside the qualifying episode may have different treatment.
Request a written itemised estimate, group only comparable covered lines, and enter actual patient-payment amounts for the rest.
HIRA procedure-code anchors
The following identifiers help a patient ask whether the written operation name and estimate describe the intended bowel segment and reconstruction.
They are not package prices, eligibility decisions, or a complete claim map.
A hospital can use a different combination when several procedures, a stoma, a reversal, adhesiolysis, or another service is performed together.
HIRA procedure anchors for inflammatory bowel disease surgery planning| Code | Procedure anchor | Planning use |
|---|
| Q2650 | Small-bowel resection without lymph-node dissection | Crohn small-bowel or ileocecal discussion |
| Q2671 | Right or left hemicolectomy without lymph-node dissection | Segmental colon discussion |
| Q2672 | Total colectomy without lymph-node dissection | Extent-of-colectomy discussion |
| Q2673 | Partial colectomy without lymph-node dissection | Partial colon-resection discussion |
| Q1262 | Subtotal colectomy without lymph-node dissection | Initial ulcerative-colitis stage discussion |
| Q2925 | Total colon and rectum resection with ileostomy, without lymph-node dissection | Permanent end-ileostomy discussion |
| Q2926 | Total colon and rectum resection with ileal pouch-anal anastomosis, without lymph-node dissection | Restorative pouch and stage discussion |
Ask the hospital to write the expected operation name, code or code family, stage, and included services on the estimate.
Then compare that document with the consent discussion rather than using this table to select an operation.
The official fee schedule can change, and the calculator intentionally does not attach a hard-coded nationwide price to any code.
How to request an itemised whole-plan estimate
- Write down the disease and current special-case status.
Confirm whether V130 or V131 registration is active and whether the proposed admission is being processed under that registration.
Registration alone does not classify every invoice line.
- Confirm the operation and bowel extent.
Ask which small-bowel, ileocecal, colon, rectal, pouch, anastomosis, fistula, abscess, or stoma procedures are planned.
Record the procedure identifiers offered by the hospital and the contingencies that could alter the operation.
- Define the stage scope.
Mark whether the estimate covers one admission, every planned stage, stoma creation, and stoma reversal.
If a later stage has no estimate yet, do not silently assume that the first admission amount will repeat unchanged.
- Separate covered and non-covered lines.
Ask for the covered charge total, expected patient payment, non-covered item names, and non-covered amounts.
Keep meals, room differences, selective benefits, and other separately rated items visible instead of blending them into a single percentage calculation.
- Add care after discharge.
Obtain a plan for clinic visits, medication, laboratory monitoring, imaging, endoscopy, nutrition support, wound care, and stoma review.
Use expected patient payments, not the provider’s full billed charge, when an item is already quoted as a patient amount.
- Estimate household cash flow.
Check paid leave, sickness-related benefits if applicable, employer support, caregiver availability, transport, temporary accommodation, and stoma supplies.
Enter the remaining net gap after confirmed support rather than the household’s normal gross income.
- Confirm private-insurance treatment before subtracting it.
Give the insurer the diagnosis, operation name, expected admission, and covered and non-covered lines.
Ask for documentation requirements and whether a payment is an estimate or an approval.
Calculation method
1. Effective covered patient-share rate
The registered special-case scenario uses 10%.
The ordinary inpatient comparison uses 20%.
The custom scenario uses the percentage entered from the itemised hospital estimate, bounded between 0% and 100%.
2. Covered and medical out-of-pocket amounts
Covered patient payment equals the covered hospital-charge total multiplied by the effective patient-share rate.
The planning NHIS share equals the covered total minus that patient payment.
Medical out of pocket equals covered patient payment plus non-covered hospital charges plus post-discharge medical-institution spending.
3. Stoma and recovery cash needs
Stoma-supply cost equals months of expected use multiplied by monthly out-of-pocket supply spending.
Income interruption equals recovery-planning weeks multiplied by the net weekly income gap.
Non-medical cash need equals stoma supplies plus caregiver and transport spending plus income interruption.
4. Gross cash need and insurance
Gross cash need equals medical out of pocket plus non-medical cash need.
Recognised insurance payment is the smaller of the entered insurer payment and medical out of pocket.
Medical cost after insurance equals medical out of pocket minus recognised insurance payment.
5. Incremental tax credit and net burden
The tool calculates the eligible annual medical-expense base before and after adding medical cost after insurance.
It multiplies only the increase in that base by 15%.
Net patient burden equals gross cash need minus recognised insurance payment minus the estimated incremental tax credit, with a floor of zero.
6. Planning range
The uncertainty amount equals net patient burden multiplied by the entered variation percentage.
The lower bound cannot fall below zero, and the upper bound adds the same reserve.
This range is a budgeting buffer, not a confidence interval or complication forecast.
Worked example from the default inputs
Worked inflammatory bowel disease surgery budget example| Step | Calculation | Result |
|---|
| Covered patient payment | KRW 8,000,000 × 10% | KRW 800,000 |
| Planning NHIS share | KRW 8,000,000 − KRW 800,000 | KRW 7,200,000 |
| Medical out of pocket | KRW 800,000 + KRW 0 + KRW 300,000 | KRW 1,100,000 |
| Salary threshold | KRW 50,000,000 × 3% | KRW 1,500,000 |
| Incremental tax credit | Medical base does not exceed threshold | KRW 0 |
| Net patient burden | No insurance and no non-medical cost | KRW 1,100,000 |
| 15% planning range | KRW 1,100,000 ± 15% | KRW 935,000–1,265,000 |
This example deliberately contains no official operation price.
It demonstrates how the formulas behave after a user supplies a hypothetical covered quote.
Replacing the input with a hospital estimate can change every downstream number, and a separately rated invoice line should be entered in the correct category rather than hidden inside the 10% calculation.
Tax-credit variation in the same example
If other eligible annual medical spending is KRW 1,000,000, the pre-surgery credit base remains zero because it is below the KRW 1,500,000 salary threshold.
Adding KRW 1,100,000 of unreimbursed eligible surgical medical spending creates a post-surgery base of KRW 600,000.
Applying 15% produces an estimated incremental credit of KRW 90,000, so the example net burden falls from KRW 1,100,000 to KRW 1,010,000 before any non-medical costs.
Planning for an ileostomy without hiding the monthly cost
A stoma may be temporary to divert bowel contents while a lower anastomosis or pouch heals, or it may be permanent as part of the chosen surgical plan.
The exact indication, construction, expected duration, and reversal timing are clinical decisions.
The financial task is to separate the operation that creates or closes the stoma from the supplies and household support needed between admissions.
Before discharge
- Confirm whether stoma creation is included in the operative estimate
- Ask which initial products and education are supplied by the hospital
- Record the stoma-clinic follow-up schedule and patient payment
- Ask who will document or prescribe products needed for support programs
- Plan transport and caregiver help for the early adaptation period
For the monthly calculator input
- Use the expected months until reversal or the chosen planning horizon
- Enter cost after confirmed insurance, benefit, or product support
- Include pouches, barriers, seals, skin products, and disposal needs actually paid by the household
- Do not assume a temporary stoma produces only one month of supplies
- Recalculate if the reversal schedule or product needs change
A cash-flow example
Six months of supplies at KRW 120,000 per month create a KRW 720,000 stoma-supply budget.
Eight weeks of net income interruption at KRW 300,000 per week create KRW 2,400,000 of income loss.
Adding KRW 500,000 of caregiver and transport spending produces KRW 3,620,000 of non-medical cash need, which the calculator keeps outside the medical tax-credit base.
Private insurance: subtract confirmation, not hope
Korean indemnity and lump-sum policies differ by contract generation, enrollment date, exclusions, riders, covered-service status, and claim review.
The calculator does not identify a policy generation, interpret exclusions, or promise reimbursement for a robotic, non-covered, stoma, room, or material line.
It simply accepts an amount that the user has chosen to treat as confirmed or conservatively expected.
Information to give the insurer
- Diagnosis and special-case code if applicable
- Exact proposed operation and procedure identifiers
- Number and purpose of planned admissions
- Covered and non-covered itemised estimate
- Robotic access, private room, materials, stoma creation, and reversal lines
- Required certificates, operative notes, receipts, and detailed statements
How the calculator protects the estimate
Insurance payment cannot exceed medical out-of-pocket spending in the formula.
If medical out of pocket is KRW 1,100,000 and the user enters KRW 5,000,000, only KRW 1,100,000 is recognised.
The remaining entry is not used to reduce lost income or caregiver spending.
This conservative cap also prevents reimbursed medical spending from remaining in the tax-credit calculation.
Actual claims and tax documents must still use the amounts finally paid and reimbursed.
Update the calculator after the insurer issues a decision.
The 2026 medical-expense tax-credit estimate
Statutory basis and effective date
Article 59-4(2) of the Income Tax Act establishes the medical-expense tax-credit structure used here.
The current law record is MST 280405, and the relevant article text used by the calculator is effective January 1, 2026.
The basic calculation uses eligible medical spending above 3% of gross salary and a 15% credit rate.
The ordinary dependant group can have a KRW 7,000,000 cap on the credit base.
Medical expenses for the taxpayer, persons aged 65 or older, persons with disabilities, and qualifying severe or rare-intractable disease groups can fall in the no-KRW-7,000,000-cap category under the statutory structure.
The person must choose the calculator group that matches the actual tax relationship and eligibility rather than assuming that a diagnosis alone resolves every tax requirement.
Before-surgery base
Start with other eligible annual medical spending after removing amounts reimbursed by insurance or another payer.
Subtract gross salary × 3%.
Apply a floor of zero and, for the ordinary-family group, the KRW 7,000,000 cap.
After-surgery base
Add current eligible medical spending after recognised insurance payment to the other annual medical spending.
Apply the same salary threshold, floor, and selected cap.
The difference between after and before is the portion attributed to the current surgical episode in this planning model.
Estimated incremental credit
Multiply the increase in the credit base × 15%.
Do not include income interruption, ordinary transport, caregiver spending, or the calculator’s conservatively separated stoma-supply budget in this amount.
A real return also depends on eligible receipts, dependant rules, insurer reimbursement records, and available tax liability.
A tax credit is not the same as an immediate hospital discount
The gross cash-need result shows what may need to be paid before later insurance and tax effects.
The incremental credit may be realised only through the applicable year-end settlement or tax return and can be limited by the final tax calculation.
Keep enough short-term liquidity for the hospital and household payments even when the final net-burden estimate is lower.
Approach labels do not determine coverage or clinical value
Open
Open access can be planned or can become necessary during an operation.
The label alone does not reveal the admission length, complication risk, recovery course, or final patient payment.
Use the itemised estimate and surgeon’s explanation.
Laparoscopic
Laparoscopic access can involve dedicated instruments and a different operative plan.
A smaller incision description does not prove that every line is covered, non-covered, cheaper, or clinically preferable.
Confirm materials and possible conversion with the hospital.
Robot assisted
The Korean calculator treats robot assisted as an informational choice and does not assign a national price.
Any separately quoted non-covered robotic amount must be entered from the hospital estimate.
Clinical suitability and alternatives belong in informed consent.
Four practical planning scenarios
Scenario A: Crohn ileocecal resection with continuing medicine
The hospital provides one estimate for the admission and confirms V130 use for qualifying covered care.
The household enters the covered and non-covered totals, then adds expected post-discharge visits, prescriptions, nutrition follow-up, and recurrence surveillance as patient payments.
The procedure choice changes the checklist to Q2650, Q2671, and Q2673 questions without changing the entered quote.
The user then compares the surgical episode with the separate IBD biologic-cost calculator for long-term therapy.
This prevents one-time surgery cash need from being mistaken for the entire future disease-management budget.
It also makes clear that surgery does not automatically end medicine costs.
Scenario B: Urgent subtotal colectomy followed by later pouch planning
The first estimate covers only subtotal colectomy and temporary ileostomy under a Q1262-related discussion.
The user runs the calculator for stage one only and labels the scope in household notes.
Later proctectomy, pouch creation, and reversal are not assigned the same price because no written estimates exist yet.
Stoma months and monthly product spending are entered for the expected interval, with a variation reserve for schedule changes.
When the next plan becomes available, the household creates a new run and a separate full-plan summary.
No admission is counted twice.
Scenario C: Three-stage restorative proctocolectomy
The hospital provides a combined quote that includes all three admissions, temporary ileostomy, and later reversal.
The user enters the combined quote once and selects three stages for explanation.
The calculator does not multiply the combined amount by three.
The household separately enters stoma supplies for the expected diversion period, transport for repeated admissions, and net income gaps for each recovery period combined.
If the stage schedule changes, those household inputs can be updated without altering the original hospital estimate unless the provider issues a revised quote.
The high and low range remains a cash buffer, not a medical prediction.
Scenario D: Total proctocolectomy with permanent end ileostomy
The surgical discussion uses Q2925 as a code anchor and includes a permanent stoma plan.
The user chooses a practical supply-planning horizon up to the calculator’s 60-month input limit rather than pretending that lifetime cost can be predicted from one product price.
The monthly figure reflects expected household payment after confirmed support.
The hospital and insurer costs are kept separate from the recurring household supply budget.
The calculation can be rerun annually as products, support, income, and follow-up needs change.
This creates a maintainable budget instead of one permanently frozen lifetime estimate.
Common errors and how to avoid them
Common inflammatory bowel disease surgery cost-planning errors| Error | Why it fails | Safer method |
|---|
| Treating the default as a national price | The value is a hypothetical example | Replace it with an itemised quote |
| Applying the special-case percentage to the full invoice | Non-covered and separately rated lines differ | Apply the scenario only to grouped covered charges |
| Multiplying a whole-plan quote by three stages | The quote already includes all stages | Enter the whole-plan amount once |
| Assuming a Q code guarantees price or coverage | Codes are procedure anchors, not package prices | Verify actual codes and charge status with the hospital |
| Subtracting an unconfirmed insurance maximum | Policy review can change the payment | Use insurer-confirmed or conservative payment |
| Putting lost income into medical tax expenses | Income loss is not medical-institution spending | Keep it in non-medical cash need |
| Ignoring stoma supplies between stages | Recurring products continue outside the operation bill | Use months × monthly out-of-pocket spending |
| Assuming Crohn surgery ends all treatment | Recurrence monitoring and medicine can continue | Add follow-up and long-term treatment planning |
Frequently asked questions
Does V130 or V131 make every hospital line 10%?
No.
The 10% rule applies to qualifying covered care within the registered special case.
Non-covered, selective-benefit, full patient-payment, meal, and out-of-scope lines can follow different rules, so use the itemised estimate.
Does the procedure code tell me the total operation price?
No.
Q2650, Q2671, Q2672, Q2673, Q1262, Q2925, and Q2926 identify procedure concepts used as consultation anchors here.
Anesthesia, admission, simultaneous procedures, stoma work, materials, imaging, pathology, and follow-up can create separate lines.
Should I enter one stage or the whole surgical plan?
Either can work if every input uses the same clearly labelled scope.
Enter one stage when the quote covers one admission, or enter the combined total once when the quote covers the full plan.
Never multiply a combined estimate by the number of stages.
Can the calculator decide between permanent ileostomy and IPAA?
No.
The choice involves disease status, anatomy, function, risks, goals, fertility considerations, continence, medicines, and clinical judgment.
The tool only helps compare the documented household costs after a clinical plan has been discussed.
Is Crohn disease cured after the diseased bowel is removed?
Surgery can treat complications and remove diseased segments, but Crohn disease can recur and ongoing medicine or surveillance may be required.
Include expected follow-up in the budget and use the separate long-term treatment calculator where relevant.
Clinical follow-up should be based on the treating team’s plan.
Are stoma supplies automatically eligible for the medical tax credit?
The answer can depend on purchase route, documentation, benefit treatment, and the applicable tax rules.
The calculator conservatively excludes the stoma-supply budget from the automatic medical-expense base.
Confirm actual receipts and eligibility with the National Tax Service or a qualified tax professional.
Is the tax-credit result a guaranteed refund?
No.
It is an incremental estimate based on entered salary, other eligible spending, insurance reimbursement, the selected cap group, and the statutory rates.
Final dependant eligibility, evidence, reimbursed amounts, and available tax liability can change the realised credit.
Why does the English calculator screen look simpler than the Korean calculator?
The English P8 screen is a compact planning interface, while this guide documents the detailed Korean implementation.
For the full disease, procedure, stage, special-case, stoma, income-loss, insurance, and incremental-tax calculation, use the Korean route or reproduce the itemised worksheet described here.
Both routes treat starting KRW values as editable examples rather than official prices.
Official and clinical source map
The calculator distinguishes legal cost-sharing rules from procedure identifiers and clinical background.
A legal source can establish a patient-share rule but cannot choose an operation, while a clinical source can explain a pathway but cannot determine one hospital’s invoice.
The following map shows how each source is used.
Source roles for the IBD bowel resection surgery cost calculator| Source | Reference | Verified point | Not used for |
|---|
| National Health Insurance Act Enforcement Decree | MST 283469 | Ordinary inpatient covered-care planning framework and 20% comparison | A hospital-specific invoice |
| Special-case administrative rule | Notice 2026-101 | 10% rule, V130 and V131 listings, five-year registration framework | Automatic registration or claim approval |
| Income Tax Act Article 59-4 | MST 280405 | 3% salary threshold, 15% credit, KRW 7,000,000 ordinary-family cap structure | Final tax return or refund |
| HIRA fee-schedule material | Q2650–Q2926 | Q2650, Q2671, Q2672, Q2673, Q1262, Q2925 and Q2926 anchors | A universal operation price |
| KDCA Crohn disease information | Clinical | Surgery is not curative, bowel-preserving context, continuing care | Patient-specific surgical selection |
| KDCA stoma information and Korean IBD clinical education | Clinical | Temporary or permanent stoma and staged-pathway context | A guaranteed stage count or recovery date |
The official rule set and constants were verified on July 23, 2026.
Laws, notices, fee schedules, and administrative practices can change after that date.
Recheck the hospital, NHIS, HIRA, National Law Information Center, National Tax Service, and insurer sources when an operation or tax filing occurs later.
Final review before relying on the budget
Hospital review
- Exact operation name and expected code family
- Bowel segment and expected extent of resection
- Anastomosis, pouch, stoma creation, and reversal scope
- One-stage, two-stage, or three-stage inclusion
- Covered, selective-benefit, full-payment, and non-covered lines
- Post-discharge medicine, imaging, endoscopy, nutrition, and clinic plan
Household review
- V130 or V131 registration and encounter application
- Insurer-confirmed payment and claim documents
- Stoma months and monthly payment after support
- Caregiver, transport, and temporary accommodation
- Paid leave, benefits, and remaining net weekly income gap
- Gross salary, other eligible medical expenses, and tax evidence
Urgent care and clinical decisions come first
Do not delay urgent evaluation, admission, or treatment to complete a cost worksheet.
Severe pain, obstruction symptoms, bleeding, fever, dehydration, rapidly worsening condition, or a clinician’s urgent instruction requires appropriate medical attention.
Use this calculator after the immediate clinical need is addressed and with a written estimate whenever possible.
Turn the clinical plan into an itemised cash plan
Confirm the operation scope, stage coverage, V130 or V131 application, covered and non-covered lines, stoma needs, and insurer documentation.
Then replace every hypothetical input with a household-specific amount and rerun the budget when the plan changes.
Keep one-time surgery cash need separate from long-term IBD medicine and surveillance costs.
