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.

Full definition

What it is in practice

CMS splits many radiology and pathology codes into Professional (26) and Technical (TC) components. The PFS PC/TC indicator in the RVU file determines which codes split.

How it shows up in your practice

When the practice owns the equipment and personnel, bill the global service. When only providing interpretation (e.g., reading films at a hospital), append 26.
