Why a pulmonary function test does not have one universal price
Pulmonary function testing is a family of procedures rather than one fixed package.
Spirometry or a flow-volume curve, pre/post bronchodilator measurements, lung-volume testing, carbon-monoxide diffusing capacity, and cardiopulmonary exercise testing use different equipment, preparation, staff time, and measurement steps.
A symptom review, preoperative assessment, and chronic respiratory follow-up may therefore produce very different orders.
The household budget can also include consultation and interpretation, bronchodilator medication and administration, pretest ECG or laboratory work, transport, companion time, and lost income.
A Korean service code or relative-value point does not by itself include provider-level billing, same-day rules, individual benefit recognition, supplies, and every add-on needed for a final patient price.
This calculator therefore starts all money and time fields at zero and uses only provider-confirmed patient amounts and a payout confirmed for the same full plan.
Zero is not a national average or proof that an item is free
A selected test with KRW 0 or zero minutes may simply mean that the value has not been confirmed.
Review the warning panel and ask the booked provider for the actual patient amount, billing unit, and expected onsite time before relying on the result.
Separate the ordered test items before comparing quotes
Spirometry or flow-volume curve
Measures air volume and flow during forceful breathing. Confirm whether basic spirometry and the flow-volume curve are one quoted item.
Pre/post bronchodilator testing
Repeats measurements after an inhaled medicine. Confirm medication, administration, waiting, and repeat measurements.
Lung-volume testing
May use nitrogen washout, helium dilution, or body plethysmography. Copy the clinician-selected method and provider billing unit.
Diffusing capacity (DLCO)
Measures carbon-monoxide transfer across the lungs. Confirm repetition, preparation, and interpretation scope.
Cardiopulmonary exercise testing
Records respiratory and cardiovascular responses during exercise. Align pre-assessment, monitoring, recovery, and safety instructions.
Other confirmed PFT item
Use this only for another ordered pulmonary-function item. Keep imaging, treatment, and long-term disease-management costs separate.
Follow provider instructions for preparation and medicine
The Korea Disease Control and Prevention Agency health portal describes general spirometry preparation that includes avoiding smoking within one hour, alcohol within four hours, strenuous exercise within 30 minutes, and a heavy meal within two hours of the test.
It explains that bronchodilator response measurements are commonly repeated 10 to 20 minutes after inhalation and that spirometry attempts may be repeated to obtain acceptable quality.
The actual test appointment can use different preparation, fasting, inhaler, and medicine instructions based on the clinical purpose, so only the treating team or booked laboratory should tell you what to change.
Never stop medicine because of a cost estimate
This tool does not decide medicine withholding, contraindications, oxygen use, exercise safety, or test eligibility.
Urgent symptoms such as severe new breathlessness, chest pain, or fainting need prompt clinical assessment rather than a price comparison.
A quote-entry workflow that avoids double counting
- Align the care setting.
Record outpatient, day test and recovery, or testing during admission together with the total visit count.
- Select only ordered tests.
Turn on spirometry, bronchodilator response, lung volumes, DLCO, CPET, or another item only when it belongs to this plan.
- Copy billing units and patient amounts.
Use the provider-confirmed unit count and actual patient amount per unit, not a relative-value point or the total gross charge.
- Separate medical add-ons.
Enter consultation and interpretation, bronchodilator medicine or supplies, pretest assessment, and other medical cost outside the test rows.
- Add indirect cost and confirmed reimbursement.
Transport and companion time multiply by visits, while lost income covers the full plan. Use only a payout confirmed for this exact scope.
- Finish all eight confirmations.
Test names, units, billing category, inclusions, medicine instructions, schedule, safety instructions, and insurance documents must be checked for a like-for-like comparison.
Formula and cost boundaries
Core formulas
Test-line cost = actual patient amount per unit × provider-confirmed units.
Medical cost before reimbursement = test costs + consultation and interpretation + medication and supplies + pretest assessment + other medical cost.
Applied reimbursement = smaller of medical cost and the payout confirmed for the same plan.
Indirect cost = transport per visit × visits + companion time per visit × visits + lost income for the plan.
Household cost after reimbursement = medical cost − applied reimbursement + indirect cost.
Onsite time = included test minutes × units + preparation + recovery.
A covered patient amount must already reflect the provider’s billing result, so the calculator never applies another 30%, 40%, 50%, or 60% copay to it.
A confirmed payout larger than medical cost is capped at medical cost and is never used to erase transport or lost income.
Cost per onsite hour is household scheduling arithmetic, not a measure of test quality, accuracy, efficiency, or staff expertise.
Fictional Provider A and B example
These numbers exist only to verify the calculation and are not a Korean national average, market range, public tariff, or recommended price.
Both fictional providers include one unit each of spirometry, pre/post bronchodilator testing, lung volumes, and DLCO, with 120 test minutes, 15 preparation minutes, and 20 recovery minutes.
Fictional Provider A and Provider B pulmonary-function-test cost comparison| Item | Provider A | Provider B |
|---|
| Test-line total | KRW 230,000 | KRW 220,000 |
| Consultation, interpretation, medicine, and pretest assessment | KRW 60,000 | KRW 70,000 |
| Medical cost before reimbursement | KRW 290,000 | KRW 290,000 |
| Transport, companion time, and lost income | KRW 130,000 | KRW 125,000 |
| Cash needed before reimbursement | KRW 420,000 | KRW 415,000 |
| Insurer-confirmed payout | KRW 50,000 | KRW 30,000 |
| Household cost after reimbursement | KRW 370,000 | KRW 385,000 |
| Expected onsite time | 155 minutes | 155 minutes |
Before reimbursement
Provider B needs KRW 5,000 less cash, but the household still needs roughly KRW 420,000 before either payout arrives.
After confirmed reimbursement
Provider A is KRW 15,000 lower after the two different confirmed payouts.
A policy name or generation alone never creates this input.
Korean NHI and non-covered-care basis verified in 2026
On August 26, 2026, the Korean Ministry of Government Legislation OPEN API showed National Health Insurance Act ID 001971, MST 276651, Articles 41 and 44 as current, together with Enforcement Decree ID 002813, MST 283469, Article 19 and Appendix 2 serial 17976571.
Medical Care Benefit Rules ID 006697, MST 285513, Articles 5 and 9, Medical Service Act ID 001788, MST 285327, Articles 45 and 45-2, and Medical Service Act Enforcement Rule ID 007863, MST 286963, Article 42-2 were also checked as current on that date.
The current Health Insurance Benefit and Non-benefit List and Relative Value Points was administrative-rule ID 36723, serial 2100000283494, MOHW Notice No. 2026-160, effective July 31, 2026.
HIRA’s 2026 fee materials list basic pulmonary-function testing F6001, basic testing with a flow-volume curve F6002, lung-volume methods F6004 through F6006, carbon-monoxide diffusing capacity F6010, and cardiopulmonary exercise testing F6012.
Those identifiers help a patient ask a precise billing question, but they do not guarantee a final patient amount, NHI recognition, or private-insurance payout.
A September 1 future notice is not pre-applied
MOHW Notice No. 2026-173, serial 2100000284212, was issued on August 24 but was scheduled to take effect on September 1, 2026 after this page’s verification date.
Its final effect on relevant items or billing criteria should be rechecked from the official text after commencement; this calculator does not apply a future rule early.
Use the result as a booking checklist, not a clinical conclusion
Preoperative scheduling
Confirm the test date, interpretation date, possible repeat visit, and deadline for sending results to the surgical team.
Chronic follow-up
Ask whether the method matches the prior test, but never use this cost screen to diagnose COPD, asthma, restriction, or surgical fitness.
Two-provider comparison
If included tests, units, minutes, visits, or preparation differ, align the scope before interpreting the price difference.
Insurance documents
Confirm which receipt, itemized statement, service code, and medical record documents are needed with both provider and insurer.
Questions for the booked provider
- What are the exact ordered test names, codes, and billed units?
- Are bronchodilator medicine, administration, waiting, and repeat measurement included?
- Does the quote include consultation, interpretation, and result review?
- What inhaler, medicine, food, smoking, and exercise instructions apply to me?
- What is the total stay including preparation, waiting, testing, and recovery?
- Does CPET need pre-assessment, a companion, or specific safety clearance?
- Can the estimate separate covered patient payment, non-covered care, and full self-pay care?
Frequently asked questions
Are spirometry and pulmonary function testing the same?
The terms may be used loosely, but a pulmonary-function order can include lung volumes, DLCO, or exercise testing in addition to spirometry. Confirm the exact items.
Does everyone need a bronchodilator response test?
No. The clinical purpose and individual situation determine the order. This calculator does not select tests or diagnose disease.
Can a Korean NHI code produce the patient price?
No. The provider must confirm the actual patient amount because a code and relative-value point do not settle the complete episode bill.
Should I apply a copay percentage again?
No. A covered patient-payment input already reflects provider billing. Applying another percentage would double count the patient share.
Does a zero payout mean that insurance excludes the test?
Not necessarily. Zero may be an unconfirmed value. Ask the insurer about this exact test scope, codes, setting, limits, and documents.
Does the lower estimate identify the better provider?
No. The result compares entered scope, money, and time only. It does not evaluate suitability, equipment, quality, interpretation, or access.
