On January 1, 2018, long-utilized HCPCS code G0364, Bone marrow aspiration performed with bone marrow biopsy through the same incision on the same date of service, will be retired. It is currently used for Medicare billing when both a needle biopsy and aspiration of bone marrow are performed through the same access site. It is an add-on code reported in addition to the code for the biopsy (38221). 

Effective January 1, new CPT code 38222, Diagnostic bone marrow; biopsy(ies) and aspiration(s), will be reportable and combines the two procedures into a single code.
