Contract Labor Reporting Can Influence Your Medicare Wage Index and Reimbursement

Contract labor is a significant cost component for many hospitals and health systems — but it can also influence your Medicare wage index, which directly affects inpatient reimbursement under the IPPS. The wage index is calculated based on the average hourly wage reported for all hospital payroll and certain contracted labor costs. Ensuring contract labor is correctly identified and reported can raise your wage index and improve Medicare payments.

What Contract Labor Can Be Included

Hospitals may include contract labor wages and hours for a range of roles in their wage index reporting, including:

  • Direct patient care personnel (e.g., nursing, diagnostic, therapeutic, rehabilitation, pharmacy)
  • Top-level management (CEO, COO, CFO, nursing administrator)
  • Administrative physicians (Medical Director, Chief of Medical Staff, physicians in administrative roles)
  • Administrative and general support functions (legal, data processing, tax preparation)
  • Contracted dietary and housekeeping personnel

Contracted Part A physicians follow similar guidelines: their written contract must substantiate both compensation and the amount of time spent on duties reported in the wage index.

Documentation Matters for Audits

Medicare Administrative Contractors (MACs) routinely review wage index submissions and audit supporting documentation. Lack of clear contracts or vendor invoices that tie labor hours and costs to allowable wage index categories can result in disallowances — reducing your average hourly wage input and lowering your wage index factor.

Best Practices for Members

  • Work proactively with vendors to obtain reliable, contract-specific data that includes labor hours and wage amounts.
  • Maintain detailed contracts that clearly define services, compensation, and time commitments.
  • Prepare packet summaries and organized supporting documents to demonstrate compliance during MAC reviews.
