Article Overview
This CPT Assistant article from Fall 1991 reviews how to distinguish procedures that are reported on their own from procedures that are reported only in combination with another service.

The discussion spans broad examples from integumentary, musculoskeletal, cardiovascular, digestive, and nervous system coding.
