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 publishes GPCI values by locality. Three GPCIs (work, PE, MP) multiply the corresponding RVU components before applying the Conversion Factor.
How it shows up in your practice
GPCI changes are usually modest year-to-year but accumulate over rebasing cycles. Multi-state practices must apply the right locality per service location.
