CPT code 82272 – Fecal occult blood test billing guide

Key takeaways

CPT code 82272 reports a qualitative guaiac fecal occult blood test on 1-3 specimens, performed for reasons other than colorectal cancer screening.

Pair 82272 with the symptom or condition that prompted the test, such as K92.1 melena or R19.5, never a Z12 screening code.

Routine guaiac screening bills 82270, and screening FIT bills 82274 or, on Medicare claims, HCPCS G0328.

Medicare recognizes 82272 as a waived test without modifier QW, but the performing site still needs a valid CLIA certificate.

Pabau, the practice platform we build, supports CPT charge entry and Claim.MD claim submission, so your coder’s 82272 line goes out as entered.

CPT code 82272: official descriptor and when to use it

CPT code 82272 is the guaiac-based fecal occult blood test (gFOBT) performed on 1-3 stool specimens for a diagnostic reason. The AMA descriptor reads: Blood, occult, by peroxidase activity (eg, guaiac), qualitative; feces, 1-3 simultaneous determinations, performed for other than colorectal neoplasm screening.

That closing clause decides the code. 82272 is for patients whose symptoms, findings or conditions suggest bleeding in the gut. Typical reasons are dark stools, unexplained anemia or a known bleeding source. A guaiac test done to screen an asymptomatic patient for colorectal cancer belongs to CPT code 82270 instead.

The test detects heme-mediated peroxidase activity on guaiac-impregnated paper. Stool is applied to a test card, developer solution is added, and the result is read as positive or negative. It gives no quantity.

CPT code 82272 vs 82270 vs 82274: choosing the right code

Three CPT codes and one HCPCS code cover stool occult blood testing, and each answers two questions differently. Which chemistry was used, guaiac or immunoassay? And was the test screening or diagnostic?

Billing 82272 for a routine screening test, or 82270 for a symptomatic patient, puts the wrong code on the claim. If your coding software auto-suggests a code, check its descriptor against the current CPT code set before you accept it.

Why screening rules do not apply to CPT code 82272

Because 82272 excludes colorectal cancer screening by definition, none of the screening benefit rules attach to it. That includes the Medicare screening frequency, the zero cost-share for preventive services, the Z12 screening diagnosis and modifier 33.

• Medicare screening benefit: NCD 210.3 covers screening FOBT once every 12 months from age 45, billed as 82270 or G0328. It does not cover 82272.
• USPSTF and the ACA: the USPSTF recommendation gives screening a Grade A for ages 50-75 and a Grade B for ages 45-49. The ACA zero cost-share follows those grades and applies to the screening codes only.
• Modifier 33: it flags a preventive service on commercial claims, so it does not belong on 82272.
• Z12.11 and Z12.10: these screening encounter codes describe a screening test, so they contradict the 82272 descriptor.

If the documentation shows a routine screening test, rebill it under CPT code 82270 or the matching FIT code. If it shows symptoms, keep 82272 and code those symptoms.

ICD-10 codes to pair with CPT code 82272

The diagnosis on an 82272 claim must name the reason the test was ordered. Medicare checks it against the covered code list that accompanies NCD 190.34. Confirm each code is valid in the ICD-10-CM code set in force on the date of service.

Documentation rule: the visit note must record the symptom or condition you code. Confirm each diagnosis against the current NCD 190.34 covered code list before you bill Medicare. Payers compare the note with the claim during audits.

Anemia workups need the most care. Report D50.0 only when the note ties the anemia to chronic blood loss, and D50.9 while the cause is still unknown.

Medicare coverage and payment for CPT code 82272

Medicare Part B covers diagnostic FOBT under NCD 190.34 when the record supports one of its indications:

• A known or suspected condition of the alimentary tract that might cause bleeding into the intestinal tract
• Unexpected anemia
• Abnormal signs, symptoms or complaints that might be associated with gastrointestinal blood loss
• Patient complaints of black or red-tinged stools

The NCD also sets two limits. The test is reported once for up to three separate specimens. Some patients take NSAIDs and have a history of GI bleeding but no other signs or symptoms. For them, testing is generally appropriate no more than once every three months.

Medicare pays 82272 under the Clinical Laboratory Fee Schedule, so it has no technical and professional split. Check the current year’s file for the national limit. Medicare Part B usually charges the patient no deductible or coinsurance for covered clinical laboratory tests.

A diagnostic test needs an order from the treating practitioner, and the ordering provider’s NPI goes on the claim. Medicare Advantage plans can apply their own rules, so check the plan before you assume fee-for-service coverage applies.

CLIA waiver status and modifier QW for CPT code 82272

Guaiac FOBT is a CLIA-waived test, so a practice can run it in the office under a CLIA Certificate of Waiver. Unlike most waived tests, 82272 does not need modifier QW on Medicare claims. CMS lists it among the waived codes that are recognized without QW, in Transmittal 11547 and earlier CLIA updates.

• Who bills 82272: the lab or practice that performs the test, under its own CLIA certificate.
• CLIA number: the performing site’s CLIA number goes on the claim, in item 23 of the CMS-1500 or its electronic equivalent.
• Modifier QW: not required by Medicare for 82272. Some commercial and Medicaid payers set their own rules, so check each payer’s policy.
• Test kit: confirm your card brand appears in the FDA CLIA test database before you bill it as a waived test.
• Sent-out specimens: if the practice sends cards to a reference lab, the lab bills 82272 and the practice does not.

The place of service follows the billing entity. An office running the test reports POS 11, and an independent lab billing it reports POS 81. When a hospital outpatient lab performs the test, the hospital bills it on its own institutional claim.

How to bill CPT code 82272: step-by-step billing guidelines

A clean 82272 claim comes down to seven checks before the claim leaves the practice. Insurance eligibility verification before the encounter confirms the plan is active and shows any plan-specific lab rules.

1. Confirm the purpose. A symptomatic or diagnostic indication means 82272. Routine screening of an asymptomatic patient means 82270, or G0328 or 82274 for FIT.
2. Confirm the methodology. Guaiac means 82272. Immunoassay means 82274. Check the kit package insert if you are unsure.
3. Bill one unit. One to three determinations are a single unit of 82272. Do not add units for the second or third card.
4. Code the indication. Use the symptom or condition from the visit note, such as K92.1, R19.5 or D50.0. Never use Z12.11.
5. Check modifiers. Medicare does not need QW on 82272, and modifier 33 never applies. Follow each commercial payer’s published policy.
6. Add the CLIA number and ordering NPI. Both are required on Medicare lab claims.
7. Secure an ABN when coverage is doubtful. If the diagnosis may fall outside NCD 190.34 or the test repeats early, get a signed ABN and append GA.

Common denials for CPT code 82272 and how to resolve them

Most 82272 denials trace back to six root causes. A solid denial management workflow catches the patterns early and stops them from recurring. The adjustment codes below are the ones payers commonly use, and the exact code varies by payer.

Our denial codes guide breaks down the CARC and RARC codes that accompany these denials.

Payer policies beyond Medicare: commercial insurers and Medicaid

Commercial payers and Medicaid set their own rules for 82272 on top of the Medicare framework. They differ most on cost-share, modifiers and prior authorization.

Commercial plans: diagnostic 82272 follows the plan’s normal lab benefit, so deductibles and copays can apply. The ACA zero cost-share covers screening tests, which bill under 82270 or 82274, not 82272. Document the symptoms clearly so the plan processes the test as diagnostic.

Medicaid: coverage rules vary by state, and some states set their own modifier or frequency rules for lab tests. Check the state’s managed care organization or fee-for-service policy before billing. Review medical billing compliance requirements for your state’s Medicaid program.

Medicare Advantage: plans follow NCD 190.34 at a minimum but may add prior authorization or network lab rules. Call the plan’s provider line if your practice has not billed 82272 to that plan before.

How Pabau supports CPT code 82272 lab billing

Many 82272 denials start at charge entry, when the wrong code, diagnosis or unit count reaches the claim. Pabau’s claims software for practices supports CPT charge entry and Claim.MD electronic claim submission. Your coder enters 82272, the diagnosis and any modifiers once, and that line goes to the payer as entered.

Claim status comes back into the same system, so your team can see which 82272 claims were paid, rejected or denied. The coding decisions stay with your coder. Pabau keeps the submitted claim and its status in one place, so you can fix a recurring cause once.

Submit lab claims from one system

Pabau supports CPT charge entry and Claim.MD electronic claim submission, so your 82272 claims go out as coded. You can then track their status in one place.

Conclusion

Settle one question before choosing the code: was this test ordered because of a symptom or a finding? If yes, bill 82272 with that diagnosis, one unit, and the CLIA number. If no, the claim belongs to CPT code 82270 or a FIT code, and the screening rules apply there.

Getting that choice right stops the most expensive 82272 errors before a claim exists. A clean claim workflow catches most of the rest by checking the diagnosis against NCD 190.34 at ordering. Book a demo to see how Pabau handles CPT charge entry and Claim.MD claim submission for lab codes like 82272.
