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
Per the CMS PFS, TC is the complement of the Professional Component for split-billable services. Modifier TC is appended when only the technical portion is billed.
How it shows up in your practice
Hospitals and imaging centers typically bill TC; the physician bills 26. When ownership is shared (e.g., mobile MRI), document the arrangement carefully.
