Common questions Copy link

Which ZIP codes does the Indianapolis, IN rate for G0121 cover?
The CMS ZIP-to-locality crosswalk maps 1,002 ZIP codes to this payment locality, and every one of them prices G0121 identically. Examples include 46001, 46011, 46012, 46013, 46014, 46015.
Why is the G0121 rate in Indianapolis, IN different from the national amount?
The national figure is a GPCI 1.000 baseline, not an amount any provider is paid. This locality's geographic practice cost indices — work 1.000, practice expense 0.927, malpractice 0.486 — scale each RVU component before the conversion factor is applied, which is why Indianapolis, IN allows less than the $378.43 baseline.
Does this G0121 rate apply everywhere in Indiana?
Yes. CMS prices Indiana as a single Medicare payment locality, so the same GPCIs — and the same allowed amount — apply statewide, not only in Indianapolis, IN. That includes Fort Wayne, Evansville and South Bend. The city name here is a search-facing label for a statewide payment locality, not a city-specific rate.
What is the facility rate for G0121 in Indianapolis, IN?
$154.52 in a facility, versus $352.37 in the office (non-facility) setting — a $197.85 difference. Only the practice-expense RVU changes with the setting: in an office the practice carries the overhead, so the professional payment is higher; in a hospital or ASC the facility bills its own fee.
What is the non-participating amount and limiting charge for G0121 in Indianapolis, IN?
A non-participating provider is paid $334.75 — 95% of the $352.37 participating fee schedule amount. On an unassigned claim the limiting charge caps what the patient can be billed at $384.96, which is 115% of the non-participating amount.
How much of the Indianapolis, IN G0121 rate does Medicare actually pay?
Medicare pays 80% of the allowed amount ($281.90) once the annual Part B deductible is met, and the beneficiary owes 20% ($70.47). Sequestration reduces Medicare's share by about 2% ($5.64), leaving $276.26. Sequestration never changes the allowed amount itself, which is why it is shown separately here.

Computed from the CMS Medicare Physician Fee Schedule Q3 2026 release : this code's RVUs from the relative value file, multiplied by payment locality 08102-00's GPCIs, then by the 2026 conversion factor of $33.4009. ZIP coverage from the CMS ZIP-to-locality crosswalk, Q3 2026 release . Releases are immutable: an amount retrieved for a past quarter always reflects that PFS release.
