Submission of new calendar year (CY) 2025 cccupational mix survey data

Section 1886(d) (3) (E) of the Social Security Act requires CMS to collect data every three years on the occupational mix of employees for each short-term, acute care hospital participating in the Medicare program, in order to construct an occupational mix adjustment to the wage index. On November 20, 2025, CMS published a notice in the Federal Register (90 FR 52406) announcing a new occupational mix survey. The new survey provides for the collection of hospital-specific wages and hours data for calendar year (CY) 2025 (that is, payroll periods ending between January 1, 2025, and December 31, 2025). The CY 2025 Medicare occupational mix survey will be applied for three years beginning with the FY 2028 wage index, and for the FY 2029 and FY 2030 wage indexes as well.

Hospitals must complete the CY 2025 occupational mix surveys and submit them on the Hospital Reporting Form, CMS 10079 (2025), to their MACs on or before June 30, 2026, via email attachment.

The CY 2025 Medicare occupational mix survey and instructions for hospitals can be found at https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/wage-index-files/2025-occupational-mix-survey-hospital
 

Hospitals must have at least 11 months of CY 2025 data in order for the data to reflect seasonal variations in staffing levels; if the hospital does not have at least 11 months of CY 2025 data (e.g., due to a change of ownership or because it is a new hospital with a short reporting period), the hospital should not submit CY 2025 occupational mix data to its MAC.

CMS expects to post the CY 2025 occupational mix survey data as a PUF on its website on July 13, 2026. Hospitals must review the file to confirm the inclusion and accuracy of their occupational mix data.  Hospitals may request revisions to their preliminary data. All requests from hospitals for changes to their FY 2028 occupational mix data must be submitted to and received by their MACs on or before September 1, 2026. A hospital that wishes to revise its occupational mix data must submit its request along with complete, appropriate, detailed supporting documentation to its MAC. Requests received after the September 1, 2026, deadline will not be accepted. MACs must receive the revision requests and supporting documentation by this date.
