Billing with code modifiers
Code modifiers help further describe a procedure code without changing the definition of the code. Modifiers can be found in the CPT (Current Procedural Terminology) and HCPCS (HCFA Common Procedural Coding System) code books.
Some modifiers are more easily misused, and for them we provide additional guidance.
