Fecal-Occult Blood Tests (FOBT) – Expanded Coverage

Through an amended national coverage determination, effective for dates of service January 1, 2004 and forward, Medicare coverage is being expanded for screening for early detection of colorectal cancer by adding an additional fecal occult blood test (iFOBT, immunoassay-based) that can be used as an alternative to the existing gFOBT, guaiac-based test.

Medicare patients aged 50 and over can only receive one FOBT per year, either G0107 (gFOBT, or guaiac-based) or G0328 (iFOBT, or immunoassay-based).

Procedure G0328 is payable under the clinical lab fee schedule.
