The Occupational Mix Survey and What Hospitals Must Get Right Before June 30
The deadline for hospitals to submit the CMS Occupational Mix Survey is June 30. For IPPS hospitals, this submission directly influences future reimbursement — and accuracy matters.
Every three years, CMS collects Occupational Mix data to calculate the Occupational Mix Adjustment Factor (OMAF). This factor impacts a hospital’s average hourly wage, which feeds into the wage index and ultimately affects Medicare reimbursement. Small discrepancies in reporting can translate into significant financial consequences.
For growth-focused hospitals and health systems, this isn’t simply a compliance exercise. It’s a strategic reimbursement lever.
Why Occupational Mix Matters
The Occupational Mix adjustment accounts for regional differences in wage costs and labor composition. Rural and community hospitals often operate with a different clinical staffing mix than large urban facilities. CMS uses this data to normalize wage comparisons across markets.
Hospitals with a higher-skilled labor mix should reflect a correspondingly higher average hourly wage. Proper reporting ensures your organization is accurately represented — and appropriately reimbursed.
Required Reporting Categories
CMS requires hospitals to calculate and report average hourly wages across five categories using payroll data from the calendar year of the survey:
- Registered Nurses (RNs)
- Licensed Practical Nurses (LPNs), Licensed Vocational Nurses (LVNs), and Surgical Technologists
- Nursing Assistants and Orderlies
- Medical Assistants
- All Other Occupations (Non-nursing Employees)
Nursing employees working in Medicare cost report cost centers must be included in the appropriate categories.
While the structure appears straightforward, aligning internal job codes and positions with CMS reporting categories can be complex. Misclassification or incomplete data can impact wage index calculations — and ultimately reimbursement.
Where Hospitals Face Challenges
Occupational Mix reporting requires collaboration across finance, HR, payroll, and reimbursement teams. Common challenges include:
- Mapping job codes accurately to CMS categories
- Reconciling payroll data with Medicare cost reporting
- Interpreting evolving CMS instructions
- Ensuring documentation supports reported classifications
Given the financial implications, precision is critical.
