Has anyone ever billed 5mg of depo medrol? If so what code did you use?
You cannot bill partial units of drugs. If you only give 5 mgs of a drug, but a full single unit per HCPCS description for the lowest about is 10 mgs then you would bill a single unit of the drug.
J1020 20 mgs (depomedrol) is the lowest increment available, it should be reported with 1 unit if only 5 mgs were given.
