Chronic Medicare Part A SNF Denials From PDPM Coding and Documentation Errors
Definition
Skilled nursing facilities routinely lose collectible Medicare revenue because claims are denied or downcoded due to incorrect PDPM reimbursement codes and missing/insufficient documentation, even when services were actually provided. OIG and CMS data show that documentation-driven denials are systemic and large in dollar value for nursing homes.
Key Findings
- Financial Impact: $10,000–$100,000+ per facility per year (within a $4.8B annual SNF improper payment pool nationally)
- Frequency: Monthly
- Root Cause: Complex PDPM rules, inaccurate or incomplete clinical documentation to support the assigned case-mix group, and billing staff not fully following Medicare documentation and coding procedures under time pressure. CMS reports that 79.1% of improper payments in SNF inpatient Medicare Part A are due to insufficient documentation, and PDPM code errors directly cause underpayment or denial of otherwise payable claims.

Financial Impact
$10,000-$50,000 annually per facility from managed care claim downcoding and appeals overhead tied to ambiguous LPN-documented diagnoses • $10,000–$35,000 annually from MCO coding errors and underpayment • $10,000–$35,000 annually from MCO denials and recovery delays
Current Workarounds
Activities Director communicates functional status informally to MDS/therapy staff via email or in-person conversation; relies on therapy/nursing to capture Section GG data; ad-hoc notation of resident activities in paper care plans (not integrated into MDS); memory-based tracking of functional improvements not formally documented • Admissions director receives admission paperwork; informal coordination with nursing and MDS coordinator on documentation completeness; no systematic check for MDS-relevant information at admission • Billing manager receives denial on therapy intensity coding; manually contacts therapy director and MDS coordinator; creates recoup spreadsheet; reactive appeal
