Common questions Copy link

Which ZIP codes does the Sacramento, CA rate for G0121 cover?
The CMS ZIP-to-locality crosswalk maps 219 ZIP codes to this payment locality, and every one of them prices G0121 identically. Examples include 94203, 94204, 94205, 94206, 94207, 94208. 9 of them span more than one payment locality, so those need ZIP+4 for an exact match.
Why is the G0121 rate in Sacramento, CA 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 1.036, practice expense 1.163, malpractice 0.536 — scale each RVU component before the conversion factor is applied, which is why Sacramento, CA allows more than the $378.43 baseline.
Which cities does the Sacramento, CA rate for G0121 cover?
This payment locality also covers Roseville and Folsom. Every location in it prices G0121 identically — the label names the largest metro, not a city-specific amount.
What is the facility rate for G0121 in Sacramento, CA?
$169.61 in a facility, versus $417.83 in the office (non-facility) setting — a $248.22 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 Sacramento, CA?
A non-participating provider is paid $396.94 — 95% of the $417.83 participating fee schedule amount. On an unassigned claim the limiting charge caps what the patient can be billed at $456.48, which is 115% of the non-participating amount.
How much of the Sacramento, CA G0121 rate does Medicare actually pay?
Medicare pays 80% of the allowed amount ($334.26) once the annual Part B deductible is met, and the beneficiary owes 20% ($83.57). Sequestration reduces Medicare's share by about 2% ($6.69), leaving $327.57. Sequestration never changes the allowed amount itself, which is why it is shown separately here.

Source & method Copy link

Computed from the CMS Medicare Physician Fee Schedule Q3 2026 release : this code's RVUs from the relative value file, multiplied by payment locality 01112-63'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.
