Effective April 1, HCPCS J1020, J1030, and J1040 have been deleted from the HCPCS code set, which is managed by CMS. A new code, HCPCS J1010, was added to replace these deleted codes. (J1010-Injection, methylprednisolone acetate, 1 mg). If 0.5mL of 30mg/mL of methylprednisolone acetate is injected, that would be represented by 15 units of HCPCS J1010.
