How much should you prepare for ostomy supplies this month?
Recurring pouch and flange orders can have different patient costs even when the number of products appears unchanged.
The prescribed quantity, covered quantity and purchase quantity may differ, and a retail order follows a different payment path from a Korean healthcare provider’s benefit claim.
This calculator uses a supply plan already discussed with your care team to separate those costs and estimate the amount to set aside for one month.
This is a South Korea outpatient supplies planner for 2026, using KRW and provider-confirmed inputs.
It does not treat all ostomy products as one fixed monthly grant.
Product classification, code, allowance period and conditions matter: extra pouches and powder with little annual allowance remaining need different entries.
The allocated allowance is what your provider has confirmed for the particular month and row; the result is not a benefit approval or reimbursement promise.
Separate surgery costs from recurring supplies
Supplies used after discharge
Pouches, baseplates and gap-filling products can remain recurring expenses after the operation.
A caregiver ordering on someone else’s behalf should record the exact code, specification and number of pieces in a pack, as well as the product name.
That record makes the next order comparable.
Hospital surgery charges and recovery-related income loss are outside this calculator.
Choose the payment channel
Select provider benefit billing or retail / full self-pay for each row.
Disability registration does not automatically turn an online receipt into a percentage-based cash refund.
Self-catheterization supply reimbursement is a separate program: its daily support amount must not be applied to ostomy products here.
Three quantities and two unit prices
Prescription, purchase and allocation
The prescribed quantity is the amount prescribed for this month’s plan; the purchase quantity is what you intend to order this month.
The allocated allowance is the provider-confirmed quantity assigned to this row after accounting for prior use, other providers, other products in the same category and applicable dates.
The lowest of the three determines the quantity included in the conditional coverage calculation.
Recognized fee and self-pay price
The covered unit fee is the provider-confirmed recognized amount before applying the patient share.
The excess / retail unit price is the actual price for unsupported quantities or retail purchases.
Do not apply the percentage again to a receipt amount that already represents only the patient copayment.
Ask which amount the bill is showing before entering it.
Enter pouches and flanges as whole pieces; enter powder and paste in grams.
A 60 g pack costing KRW 18,000 corresponds to KRW 300/g and a purchase quantity of 60, not one.
Both prices and all quantities in that row must use the same unit.
Changing a product type clears its quantities and prices to prevent accidental reuse under a different unit.
Allowances may use weekly, monthly or annual periods
The following reference explains HIRA notice history and its July 2023 consolidated handbook.
It is not a live 2026 database of every product’s listing, price or allowance.
Calculations use the current monthly allocation confirmed by your prescribing provider.
Pouches and flanges
Notice 2014-66, effective 2014-05-10, describes four per week for outpatient use, with up to one per day for specified situations including stoma-related skin complications, children under three, dementia, and two months of outpatient care after surgery.
Higher quantities are assessed case by case; inpatient recognition uses actual quantities.
This outpatient budget does not reproduce inpatient claims.
Do not automatically convert four per week into a fixed 16 or 20 per month: ask how the provider allocates the prescription period and month boundaries.
Powder, paste and gap-filling barriers
Notice 2019-83, effective 2019-05-01, describes powder up to 60 g/year and paste up to 60 g/month.
Gap-filling skin barriers have a reference of one large piece per week, or two small, strip or half-ring pieces per week, choosing one form.
These barriers are distinct from the flange that attaches the pouch.
Entering 60 g of powder as a fresh allowance every month ignores the annual period.
Confirm prior recognized use and any case-specific additional quantity needed for skin complications.
Caps, leg bags and support garments
A stoma cap collects residual output after irrigation; the reference describes one per day and excludes concurrent pouch use.
Leg bag recognition requires conditions such as prolonged outings by ambulatory patients with a urinary stoma.
Outpatient ostomy support garments are assessed case by case, including hernia or prolapse.
Selecting these products does not create a fixed monthly entitlement for every patient.
Confirm the patient share and overlapping products
Apply 20% only after checking the conditions
Annex 2 of the National Health Insurance Act Enforcement Decree includes 20% for specified regularly prescribed outpatient materials and directly related replacement procedures, 14% for infants under one, and an exception for the specified serious-disease group.
The separate notice defines the L3 material scope for ostomy disability registration.
The adult registered-reduction button only fills a number; it does not adjudicate registration or special coverage.
For unregistered patients, Medical Aid, children or special registration, enter the actual provider-confirmed share.
Calculate separately when different items have different rates.
Do not add the pouch and flange already included in a one-piece product as additional charges.
Paste and gap-filling skin barriers are ordinarily excluded from concurrent recognition, with case-specific exceptions such as skin complications requiring review.
For caps and pouches, confirm whether the use periods are separate.
For multiple products of one category, confirm that the allowance has been allocated between them.
The interface flags these combinations and withholds the affected benefit estimates until reviewed; checking the box does not authorize otherwise excluded concurrent claims.
Monthly budget formula and interpretation
- Covered quantity = min(purchased quantity, prescribed quantity, allocated monthly allowance)
- Covered amount = covered quantity × recognized covered unit fee
- Covered patient share = covered amount × confirmed patient percentage ÷ 100
- Unsupported cost = (purchase quantity − covered quantity) × excess / retail unit price
- Required monthly budget = all covered patient shares + unsupported costs + other monthly spending
The covered quantity applies only when provider billing, the item conditions and the patient percentage are confirmed.
Retail rows are fully self-paid.
Pending rows also reserve the full purchase at the excess / retail price until checked.
Unsupported quantity therefore includes both quantities beyond the entered limits and pending quantities; it is not a final legal determination of non-coverage.
Estimated insurer share is covered amount minus covered patient share, not a payment promised to your bank account.
Covered amounts and unsupported costs are rounded to whole KRW per row, followed by rounding the row’s patient share.
A provider’s truncation or bundled billing may differ.
The difference between a retail price and a benefit ceiling is not automatically added as an authorized patient surcharge.
Instead, enter a recognized billing fee already confirmed by the provider.
Fictional example: KRW 62,800 after confirmation
These figures are invented for arithmetic verification, not national prices or a statutory monthly allowance.
Assume 20 purchased and prescribed pouches, a provider-allocated allowance of 16, a covered unit fee of KRW 5,000 and an excess unit price of KRW 6,000.
For flanges, all three quantities are 16, the covered fee is KRW 4,000 and the self-pay price is KRW 4,500.
Both rows have confirmed provider billing, a 20% patient share and KRW 10,000 in extra spending.
Fictional monthly pouch and flange budget in KRW| Item | Covered amount | Covered patient share | Unsupported cost |
|---|
| Pouches | 80,000 | 16,000 | 24,000 |
| Flanges | 64,000 | 12,800 | 0 |
| Total | 144,000 | 28,800 | 24,000 |
Required spending is 28,800 + 24,000 + 10,000 = KRW 62,800, with an estimated insurer share of KRW 115,200.
A household budget of KRW 80,000 leaves KRW 17,200.
With otherwise identical confirmed inputs, a 10% share produces KRW 48,400, 0% produces KRW 34,000, and 100% produces KRW 178,000.
Loading the fictional example leaves confirmations unchecked and initially displays a full self-pay reserve of KRW 202,000.
That difference demonstrates why confirmation matters; never mark unverified conditions as confirmed to obtain a lower result.
Step-by-step entry
- Select the planning month, stoma type and disability registration status.
The household budget is money you have allocated to supplies, not an insurance benefit ceiling.
- Gather the prescription, detailed bill and product packaging.
Establish whether the system is one-piece or two-piece and which components its price includes.
- Enter the prescription, purchase and allocated allowance quantities for each item.
These are this month’s purchase and billing quantities, not consumption; the calculator does not subtract home inventory automatically.
- Enter the recognized fee and excess / retail price in matching units.
Do not mix pack, piece and gram prices, and confirm that the covered fee is before the patient-share reduction.
- Review the percentage, item conditions, overlapping combinations and extra spending.
Leave unresolved checks pending and export the table to ask the provider about them.
- Read the required spending and budget shortfall, then download CSV or print to PDF.
A changed order or prescription needs updated prices, quantities and confirmations.
Practical situations for patients and caregivers
Little annual powder allowance remains
Suppose you purchase 60 g but the provider allocates only 10 g for this month after prior annual use.
At KRW 200/g covered, KRW 300/g self-pay and a 20% patient share, the covered amount is KRW 2,000, covered copay KRW 400 and unsupported cost KRW 15,000.
The row requires KRW 15,400.
This does not create a new 10 g balance every month.
A caregiver places an extra retail order
Keep provider-billed supplies separate from products purchased directly because delivery cannot wait.
Enter the actual self-pay price in the retail row and do not count that quantity again in the provider row.
If extra purchases become frequent, discuss skin condition and product suitability with the care team instead of extending replacement intervals yourself to cut costs.
Pieces and grams are never added into a single total quantity.
Review each product’s quantity and cost separately, and use its code, allowance period and prior claims when discussing the plan with the provider.
You do not need to enter a name, identification number or detailed diagnosis; calculation inputs are not sent to a server.
Frequently asked questions
Is the monthly allowance fixed at 16?
No.
The four-per-week reference is not automatically converted to 16 for every month.
The example assumes that the provider allocated 16 for the specific period.
Does no disability registration always mean zero coverage?
No.
Registration is relevant to checking the reduction, while actual covered quantities and patient rates come from the provider.
Lack of registration does not automatically make every supply non-covered in this model.
Will an online purchase receive an 80% refund?
This calculator does not automatically reimburse retail purchases.
Distinguish healthcare-provider billing from personal retail purchases and confirm the applicable process.
Should powder be entered by the pack?
Use grams.
A 60 g pack is a purchase quantity of 60; divide its price by 60 for KRW/g.
Ask the provider for this month’s allowance after prior annual use.
What if I use paste and skin barriers together?
Check the concurrent-use exclusion and any case-specific exception.
Record the products honestly, then ask the provider about periods and allocation.
A checkbox is not benefit approval.
Does a zero result mean the supplies are free?
It may simply reflect the initial zero quantities and prices.
If checks remain pending, enter the missing quantities, fees and extras before interpreting the result.
Are special registration and Medical Aid automatic?
No.
Enter the provider-confirmed rate for the specific items and period.
Calculate separately if different products have different patient rates.
Can I reuse the result next month?
Recheck prescriptions and allocated allowances when the month changes.
Prior powder use, special-registration validity, product fees and quantities may change.
Keep a separate monthly record.
Official sources and update boundaries
Sources were checked on 2026-09-13; the check date is different from each rule’s effective date.
Before ordering, confirm current codes, unit fees, allowance periods and concurrent-use rules with the provider.
Recheck official sources after amendments and at least quarterly.
Clinical advice about products and replacement takes precedence over a household budget calculation.
Take the itemized plan to your provider
Bring the CSV or printed table with product codes, quantities, prices and pending checks, rather than only the final amount.
Update it with the provider’s answers and check any budget shortfall again.
The result can help family members share ordering costs or prepare extra funds.
Do not subtract unconfirmed support from your living budget in advance; use a plan consistent with the month’s actual purchasing arrangements.
