Where this comes up

This shows up in revenue-cycle work — claim scrubbing, charge entry, posting, A/R follow-up, and month-end close. Billers and practice managers hit this term when reconciling a payment, working a denial queue, or auditing why a claim aged past 60 days.

What it is in practice

CMS recognizes modifier 26 for procedures with PC/TC splits in the PFS RVU file. The 26-modified line bills only the physician's interpretation or supervision portion.

How it shows up in your practice

Append 26 when billing the professional component only (e.g., reading an X-ray taken at a hospital). Confirm PC/TC eligibility before using.
