Ocrevus is a physician-administered biologic billed under Medicare Part B (not the Part D pharmacy benefit). Under Part B, Medicare pays the practice for the drug (HCPCS J2350) plus its administration — but only when the claim's diagnosis (ICD-10) code supports medical necessity. Each MAC publishes the specific covered diagnoses in a Billing & Coding Article; a claim with a diagnosis outside that list is typically denied as not medically necessary (CO-50).

How to use this list when billing

Put a medically necessary, FDA-indicated diagnosis from the list above on the claim line with J2350, match the correct product code and units (check JZ/JW wastage), and document medical necessity. Because there's no drug-specific LCD, coverage is judged per medical necessity by your MAC; an off-label use can still be covered if supported by an approved drug compendium.

LCD vs. Billing & Coding Article vs. NCD

An LCD (Local Coverage Determination) is a MAC's policy on whether a service is reasonable and necessary in its region, and its companion Billing & Coding Article holds the covered ICD-10 and HCPCS code lists. A NCD (National Coverage Determination), where one exists, applies nationwide. Ocrevus has no drug-specific LCD or Article, so there is no published covered-code list — it's covered under the general Part B drug benefit per medical necessity, and the FDA-approved indications above are the practical starting point.
