G-Codes
G-codes are Healthcare Common Procedure Coding System (HCPCS) Level II codes that Medicare uses to describe services that have no matching CPT code. In home health billing, G-codes identify the discipline and type of each visit reported on the claim, such as skilled nursing, therapy, medical social work, or home health aide services. Every billable visit line on a home health claim pairs a G-code with a revenue code and units of time.
