By area, and what the calculation leaves out2 areas
| Area | Clinicians | Median change | Middle half |
|---|---|---|---|

| United States | 8,921 | −3.6% | −4.1% to −3.0% |
104 codes are new in the 2027 proposed rule (not in any 2024 code mix); 53 codes move to a national rate from a 2026 status without one (carrier-priced and others); lines in those codes are left out of the calculation.
Each clinician’s own figure, with the codes behind it, is in the Physician Report. How this is calculated.

United States: share of calculated Medicare work RVUs by setting

|---|---|---|---|---|---|
| 2020 | 2.0% | 64% | 34% | 8,332 | 39% |
| 2021 | 1.2% | 64% | 35% | 8,436 | 24% |

Telehealth-only services are codes that exist only as remote services (telephone and online visits, virtual check-ins, telehealth consultations). The share is a floor, not total telehealth: CMS publishes the place of service only as facility or non-facility and does not publish telehealth modifiers, so a video visit billed with an ordinary visit code is counted in the setting CMS records. Every year is weighted at the 2024 work relative values, so a share moves only when the services billed move. Cells of at least 11 clinicians. How this is calculated.
