Noridian Healthcare Solutions, LLC (Noridian), as the Supplemental Medical Review Contractor (SMRC) for the Centers for Medicare & Medicaid Services (CMS), is conducting post-payment review of claims for Medicare Unspecified Outpatient Dental Services Current Procedural Terminology (CPT) 41899 (Unlisted procedure, dentoalveolar structures), billed on dates of service January 1, 2019, through May 31, 2022.

The Office of Inspector General (OIG) published a report (A-06-16-05003) in March 2017 titled “Medicare Contractors’ Payments to Providers for Hospital Outpatient Dental Services Generally Did Not Comply with Medicare Requirements.” It was noted from January 2011 through December 2014, Medicare contractors paid providers for hospital outpatient dental services that may be ineligible for Medicare payment. The OIG conducted audits of six Medicare contractors and found that 542 of the 600 dental services audited did not comply with Medicare requirements.

In September 2019, Noridian, as the SMRC, completed medical review and data analysis on outpatient dental services with an overall error rate of 91%. The SMRC found that the CPT code 41899 (Unlisted procedure, dentoalveolar structures) had a claim error rate of 92% with an overpayment error rate of 95%.

Reason for Review

The SMRC was directed to perform data analysis and medical record review activities. The SMRC will perform medical record review on Part B and Part B of A claims billed with CPT code 41899 with dates of service (DOS) January 1, 2019, through May 31, 2022.
