Final answer:
To indicate that a procedure was repeated on the same patient in CPT coding, modifiers -76 or -77 are used along with the CPT code, or the units field on the claim form might be utilized, depending on the procedure and payer guidelines.
Step-by-step explanation:
When documenting services using CPT (Current Procedural Terminology) codes, if a single procedure is performed multiple times on the same patient, a modifier should be used to indicate that fact. Specifically, the modifier -76 (Repeat Procedure by Same Physician) or -77 (Repeat Procedure by Another Physician) is often added to the CPT code of the repeated procedure. For counting multiple units of a procedure, some payers might require the use of modifier -59 (Distinct Procedural Service) or an appropriate repeat procedure modifier to specify services that are not normally reported together, but are appropriate under certain circumstances. It's crucial to consult the payer's guidelines as there can be specific billing instructions for different procedures or settings.
In addition, some procedures may require the use of the units field on the claim form to indicate the number of times the procedure was performed. This is especially relevant for procedures that are typically provided in multiple units, like physical therapy or counseling sessions.
