How locality affects the amount Copy link
Office (non-facility) · Q3 2026 · Participating · Whole service
Each of this locality's geographic practice cost indices (GPCIs) scales one RVU component before the conversion factor is applied. Together they put Seattle, WA 18.3% above the national baseline.
Why is the 74183 rate in Seattle, WA 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 1.050, practice expense 1.227, malpractice 0.817—scale each RVU component before the conversion factor is applied, which is why the Seattle, WA amount is higher than the $336.01 baseline.
Formula and inputs Copy link
For the office (non-facility) amount, each of 74183's RVU components is multiplied by its Seattle, WA GPCI; the products are summed and multiplied by the conversion factor.

| Participating allowed amount The fee schedule amount a participating provider accepts as payment in full. | $397.39 |
|---|---|
| Non-participating allowed amount 95% of the participating amount. | $377.52 |
| Limiting charge Ceiling a non-participating provider may bill the patient on an unassigned claim—115% of the non-participating amount. | $434.15 |
| Medicare share 80% of the allowed amount, once the annual Part B deductible is met. | $317.91 |
| Patient coinsurance The remaining 20%. | $79.48 |

What is the non-participating amount and limiting charge for 74183 in Seattle, WA?

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 02402-02's GPCIs, then by the 2026 conversion factor of $33.4009. ZIP coverage from the CMS ZIP-to-locality crosswalk, Q3 2026 release. Past releases are never edited, so an amount for an earlier quarter always matches what CMS published for it. Coverage and coding correctness are outside this calculation.
