Why is the 73721 rate in Detroit, MI 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 0.965, malpractice 1.686—scale each RVU component before the conversion factor is applied, which is why the Detroit, MI amount is lower than the $204.41 baseline.

Formula and inputs Copy link

For the office (non-facility) amount, each of 73721's RVU components is multiplied by its Detroit, MI GPCI; the products are summed and multiplied by the conversion factor.

Source & method Copy link

Computed from the CMS Medicare Physician Fee Schedule Q4 2026 release: this code's RVUs from the relative value file, multiplied by payment locality 08202-01's GPCIs, then by the 2026 conversion factor of $33.4009. ZIP coverage from the CMS ZIP-to-locality crosswalk, Q4 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.
