Medicare Cost Report: Definition and Healthcare Context

Full name: Medicare Cost Report (Form CMS-2552 and related)

A Medicare Cost Report is an annual financial and utilization report that Medicare-participating health care facilities — including hospitals, skilled nursing facilities, home health agencies, hospices, and renal dialysis facilities — must file with CMS each fiscal year. Filed on CMS Form 2552-10 (hospitals) or facility-type-specific forms, cost reports capture total charges, operating costs by service line, Medicare utilization statistics, staffing hours, and cost-to-charge ratios. CMS compiles all cost reports in the Healthcare Cost Report Information System (HCRIS) and releases them quarterly as public-use files. Medicare Cost Reports are a primary source for hospital financial transparency research, including analysis of operating margins, uncompensated care, and Medicare payment-to-cost ratios.

How it’s used

  • Healthcare Cost Report Information System (HCRIS): Fonteum ingests HCRIS data — drawn from facility-filed Medicare cost reports — to power hospital financial transparency research, including the Hospital Margin Gap study.
  • CMS Provider of Services (POS) File: the POS file CCN is the join key for linking facility identity records to their corresponding HCRIS cost report filings across fiscal years.
  • CMS Care Compare: Medicare Cost Report data in HCRIS supplements Care Compare quality records with financial context, enabling analysis of staffing investment relative to Medicare payment.
