In CPT, what does the phrase "bilateral procedure" imply?

The phrase "bilateral procedure" in the context of CPT (Current Procedural Terminology) specifically refers to a procedure that is performed on both sides of the body. This terminology is used to indicate that the same surgical or medical procedure has been conducted on two symmetrical parts of the body, such as both knees or both hands.

This designation is important for coding and billing purposes, as it can affect reimbursements and documentation requirements. When a procedure is classified as bilateral, it typically indicates that specific codes and modifiers are applied to reflect that the procedure was done on both sides, ensuring proper recognition of the complexity and extent of the treatment provided.

The other options represent different concepts: a unilateral procedure (single side), follow-up examinations which pertain to post-procedure assessments, and experimental procedures that might not yet be widely accepted as standard medical practices.
