01-088 SNF PDPM Notification of Medical Review

Noridian Healthcare Solutions, LLC (Noridian), as the Supplemental Medical Review Contractor (SMRC) for the Centers for Medicare & Medicaid (CMS), is conducting post-payment review of claims for Medicare Part A SNF services billed on dates of service from January 1, 2020, through December 31, 2020. This notification includes the reasons for the review, documentation that will be requested in the Additional Documentation Request (ADR) letter, and resources providers/suppliers may wish to consult when submitting claims.


In July 2018, the Patient Driven Payment Model (PDPM) for Skilled Nursing Facility (SNF) billing was finalized by CMS. This new case-mix classification model was created to classify SNF patients in a covered Part A stay. Under the PDPM, the patient’s characteristics are used to predict therapy costs under the SNF Prospective Payment System (PPS) beginning October 1, 2019.

The 2021 Medicare Fee-for-Service Supplemental Improper Payment Data reported a projected improper payment estimated at $2.7 billion dollars for inpatient SNF services. Further data analysis done by CMS and the SMRC had identified a possible vulnerability in the maximization of payments by a drop in therapy utilization and/or the manipulation of other combinations of care.

Reason for Review

The SMRC was directed to perform data analysis and conduct medical record review activities. The SMRC will perform medical record review on Part A SNF claims with dates of service (DOS) January 1, 2020, through December 31, 2020.

The SMRC will conduct medical record reviews in accordance with applicable waivers/flexibilities/statutory, regulatory, and sub-regulatory guidance.
