Answer: Note that 82270 was modified in CPT 2001 to specify the method that you mention (guaiac). The code now reads
blood, occult, by peroxidase activity (e.g., guaiac); feces, 1-3 simultaneous determinations. The code modification does not change the answer to this question, however. By definition, one unit of 82270 is appropriate for reporting either a single-specimen test carried out in the physician office, or a take-home kit that requires the collection of three specimens.
You should also be aware that for Medicare patients, code 82270 should be used only to report fecal occult blood tests ordered for diagnostic purposes. If the test is ordered as a screening for colon cancer, HCPCS code G0107 (
colorectal cancer screening; fecal-occult blood test, 1-3 simultaneous determinations) should be used. Also note that Medicare has frequency limitations for the use of both of these codes. For a fuller discussion of these issues, see Careful Documentation Ensures Reimbursement for Fecal Occult Blood Test, page 73 in the October 2000 issue of
pathology/Lab Coding Alert.
