What J8541 covers

J8541 identifies oral Hemady, a branded dexamethasone product used with other antimyeloma medicines to treat multiple myeloma. Oncology practices report the drug by the amount furnished. The code distinguishes Hemady from general oral dexamethasone and injectable dexamethasone; the unit count reflects the drug amount, not the number of tablets or doses.

CMS excludes J8541 from the physician fee schedule under status E. When Medicare covers it, payment is made under another method. HCPCS assigns it Part B drug pricing, generally based on CMS quarterly Average Sales Price files, and coverage is left to the Medicare contractor’s judgment. Each unit represents 0.25 mg, so 1 mg corresponds to four units. Report units based on the amount furnished.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
