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 POS POS 11 triggers the non-facility PE component of the PFS, generally yielding higher physician payment than POS 22 (hospital outpatient).
How it shows up in your practice
Verify POS for each clinic location. Provider-based hospital outpatient departments must use POS 22, not 11.
