The following tumor markers are eligible for payment when medically necessary and should be processed as follows:
CA 125 (86304)
CA 125 is payable when reported for patients with symptoms suggestive of ovarian cancer or in those with known ovarian cancer (183.0, 198.6, 233.3, V10.43). It is also payable for patients with carcinomas of the fallopian tube, endometrium, endocervix and may be associated with the presence of a malignant mesothelioma (180.0, 182.0, 183.2, 183.8, 184.8, 198.82, 236.0-236.6, V10.42, V10.43), as well as primary peritoneal carcinoma and metastatic adeno cancer of unknown origin in the peritoneum (158.0-158.9, 197.6).
CA 27.29 or CA 15-3 (86300)
CA 27.29 or CA 15-3 are payable when reported for use in the management of patients with breast cancer (174.0-174.9, 175.0-175.9, 198.2, 198.81, V10.3).
CA 19-9 (86301)
CA 19-9 is payable when reported for monitoring response to treatment in patients with an established diagnosis of pancreatic and biliary ductal carcinoma (155.1, 156.1, 156.8, 156.9, 157.0-157.9, 197.8, 230.9, 235.3, 235.5, V10.09). This test is not indicated for making the diagnosis of pancreatic or biliary cancer.
BTA or NMP-22 (86294)
Bladder Tumor Antigen (BTA) or nuclear matrix protein 22 (NMP-22) are payable when reported as an adjunct to surveillance cystoscopy in patients with a history of bladder cancer and to monitor for eradication of the cancer, or recurrences after eradication (188.0-188.9, 198.1, 233.7, 239.4, V10.51).
There is insufficient scientific evidence to determine the efficacy of CA 125, CA 27.29, CA 15-3, CA 19-9, BTA and NMP-22 in the clinical management of malignancies other than those listed above. Therefore, when reported for cancer diagnoses other than those listed above, these tumor markers are considered experimental/investigational and not covered. A participating, preferred, or network provider can bill the member for the test. In addition, when performed for patients with non-malignant diagnoses, tumor marker testing is considered not medically necessary and not covered. A participating, preferred, or network provider cannot bill the member for the denied test in this case. When performed for asymptomatic patients, tumor marker testing is considered screening and only covered by certain groups or programs as indicated in benefits.
CA 125, CA 27.29, CA 15-3, CA 19-9 and BTA are not indicated for diagnosing. Therefore, no payment should be made to "rule out" the covered diagnoses for these markers.
Radioimmunoassay and immunohistochemical determination of the serum levels of certain proteins or carbohydrates have been developed as "markers" for various cancers. Normal cells express these chemicals in low quantities. Tumor size and grade are believed to be reflected by significant elevations in serum concentration of these markers. The uses of tumor marker testing include screening, diagnosis and monitoring response to treatment.
