In the case study of a 45-year-old male with malignant carcinoma of the inner cheek treated with Interferon Alfa-2a injections, which codes should be used?

• A. 145.0, 90782, J9213
• B. 145.0, 90782
• C. 90782, J9213
• D. 145.0, J9213

Answer: (A)

When coding this scenario, you report three things: the diagnosis that justifies the visit, the drug that was given, and the way the drug was administered. The cancer in the inner cheek is coded with the ICD-9-CM diagnosis 145.0, which covers malignant neoplasm of the lip, inner aspect (buccal mucosa). The patient received an injectable immunotherapy drug, interferon alfa-2a, so you need the HCPCS drug code that identifies that specific medication, which is J9213. Since the therapy was given by injection, you also include the CPT code for administering a therapeutic, prophylactic, or diagnostic injection used for immunotherapy, which is 90782. Putting these together—145.0 for the diagnosis, 90782 for the injection administration, and J9213 for the interferon alfa-2a drug—accurately reflects the service provided. The other options omit one of these essential components (drug code or administration code) and thus don’t fully capture the encounter.
