CPT® Code 82270 is used to report a qualitative fecal occult blood test (FOBT) that detects the peroxidase activity of hemoglobin in a single stool specimen. This test helps identify hidden (occult) blood in the stool, which may indicate gastrointestinal bleeding, polyps, colorectal cancer, or other GI conditions.
The code represents a single determination performed on one specimen, typically using a guaiac-based or chemical peroxidase method.
Key Facts About CPT® 82270
Service type: Laboratory stool test
Provider type: Physicians, qualified healthcare professionals, and laboratory personnel
Medical services included: Yes—qualitative detection of occult blood in feces
Specimen type: Stool (single sample)

- Monitoring patients with a history of GI lesions or polyps
- Assessment of abdominal pain, melena, or occult bleeding
- Routine preventive health screening in adults
When to Use CPT® 82270
CPT 82270 is appropriate when:
- A single fecal specimen is tested for occult blood using peroxidase activity
- The test is medically necessary for screening, diagnosis, or monitoring of GI conditions
- Results are used to guide further diagnostic evaluation or treatment
Examples:
- Performing a guaiac-based FOBT on a single stool sample during an annual preventive visit
- Testing a patient with unexplained iron-deficiency anemia for occult gastrointestinal bleeding
- Screening a patient with family history of colorectal cancer
- Evaluating a patient with intermittent dark stools or mild GI discomfort
Documentation Requirements
To support CPT 82270 billing, documentation should include:
- Patient identifiers and date of service
- Test ordered (fecal occult blood, peroxidase activity)
- Specimen type and collection date
- Test method and results (positive/negative)
- Clinical indication or medical necessity
- Ordering provider name and credentials
- Laboratory performing the test
Proper documentation supports coding accuracy, reimbursement, and follow-up clinical care.
Reimbursement and Coding Considerations
- CPT 82270 is reimbursed for a single qualitative determination of fecal occult blood
- Multiple determinations on separate specimens require additional CPT codes (e.g., 82274 for multiple determinations)
- Coverage depends on payer guidelines, medical necessity, and preventive versus diagnostic intent
- FOBT results may influence further diagnostic procedures such as colonoscopy or endoscopy
- Ensure accurate documentation of specimen source, method, and result for compliance
Correct coding and thorough documentation ensure proper reimbursement and clinical audit readiness.
