CPT Code: 82378 Carcinoembryonic Antigen 

Frequency Limitations: 

Serum CEA determinations are generally not indicated more frequently than once per chemotherapy treatment cycle for patients with metastatic solid tumors which express CEA or every two months post-surgical treatment for patients who have had colorectal carcinoma. It may be proper to order the test more frequently when there has been a significant change from prior CEA level or a significant change in patient status which could reflect disease progression or recurrence. Testing with a diagnosis of an in situ carcinoma is not reasonably done more frequently than once, unless the result is abnormal, in which case the test may be repeated once.

ICD-9 Codes are associated with CPT code 82378 in this policy.
