Key Coverage Criteria
- Anti-neoplastic (chemotherapy) agent CPT/HCPCS codes may be used to bill for administration of these drugs when given to treat non-oncologic (noncancer) diagnoses if the drug is medically necessary for the patient’s condition and consistent with the standard of medical practice.
- Monoclonal antibody agents and other biologic response modifiers may be administered and billed using chemotherapy administration codes for noncancer indications when the dose, route, and clinical use are appropriate and medically necessary.
- IVIG is covered for patients with common variable immunodeficiency (CVID) when initial presenting IgG levels, evidence of Pneumovax vaccination, and pre- and post-vaccine pneumococcal antibody titers demonstrate inability to produce an antibody response to protein or carbohydrate antigens, and documentation includes dual diagnoses and a statement of lack of response to protein antigen.
- IVIG is covered for patients with HIV disease and immune thrombocytopenic purpura (ITP) when the medical record documents a platelet count less than 30,000 and active bleeding supported by laboratory results.
- IVIG is covered for immunodeficient individuals with recurrent or chronic bacterial sinusitis when the record documents findings diagnostic of or highly suggestive of bacterial sinus infection (for example fever, unilateral purulent nasal discharge, unilateral facial pain) and documents prolonged and/or recurrent antibiotic therapy.
- IVIG is covered for stiff-man syndrome when the patient is under the care of a physician competent in diagnosis, meets the defined diagnostic criteria, has failed conservative therapy (e.g., benzodiazepines), and documentation shows objective response after initial treatment for continued coverage.
