Notably, most denials were not related to the necessity of the care furnished, but due to correctable documentation issues. Specifically, CMS stated:
“For the 2023 reporting period, insufficient documentation accounted for 79.1% of improper payment rates for SNF inpatient services, while no documentation (0.2%), incorrect coding (1.2%), medical necessity (0.2%), and “other” errors (19.4%) caused other improper payments.”
The compliance guidance resource also contains information on areas of particular focus the agency has identified that commonly lead to SNF Medicare Part A claim adjustments or denials. SNF clinical and billers may find it helpful to review this guidance.
