OIG and CMS Overpayment Recoveries and Sanctions for Noncompliant SNF Billing
Definition
Systemic Medicare billing noncompliance in nursing homes leads to large overpayment findings, mandatory refunds, and potential additional sanctions. OIG audits have identified tens of millions in overpayments at individual facilities, and CMS data show a multibillion-dollar yearly exposure in the SNF sector due to improper billing under Medicare Part A.
Key Findings
- Financial Impact: $31.2M+ in overpayments identified for one audited facility; $4.8B in projected SNF overpayments in a single year sector-wide
- Frequency: Monthly (sector-wide); episodic but high-impact per facility
- Root Cause: Failure to follow Medicare billing requirements, including assigning correct PDPM or reimbursement rate codes, billing for residents who did not require skilled care, and not meeting documentation standards. An OIG report on a nursing and rehabilitation center found 99% of sampled claims noncompliant, estimating significant overpayments, and CMS error statistics demonstrate persistent, systemic noncompliance across the industry.
