Immunoassay for Tumor Antigen: Billing Correction

ICD-9-CM diagnosis codes 151.0 – 151.9 were incorrectly listed as codes to bill in conjunction with CPT code 86304 (immunoassay for tumor antigen, quantitative, CA 125). The correct codes are: 151.0, 151.1, 151.2, 151.3, 151.4, 151.8 and 151.9.

CPT code 86304 is reimbursable only when billed in conjunction with ICD-9-CM diagnosis codes listed in the provider manual Pathology: Chemistry section.
