01-032 TENS Findings of Medical Review

Noridian Healthcare Solutions, LLC, as the Supplemental Medical Review Contractor (SMRC) for the CMS, has conducted post-payment review of claims for Medicare Durable Medical Equipment (DME) billed on dates of service from January 1, 2018 through December 31, 2019. Below are the review results:

Project ID Project Title Error Rate
01-032 TENS 77%

Background

Transcutaneous electrical nerve stimulation (TENS) units are effectively used to treat types of Chronic Intractable Pain and Acute Post-Operative Pain. In 2018, the Comprehensive Error Rate Testing (CERT) Medicare Fee-for Service Improper Payment Report identified an improper payment rate of 93% for the TENS service. The CERT report identified 95.9% of improper payments were attributed to insufficient documentation and 0.1% related to medical necessity. Centers for Medicare and Medicaid Services (CMS) requested the Supplemental Medical Review Contractor (SMRC) complete a review of the charges for TENS services. The SMRC project looked at both rental and purchase of TENS units and associated supplies for improper payments in relation to insufficient documentation and medical necessity.

Reason for Review

This TENS project focused on TENS units and associated supplies billed for Chronic Intractable Pain and Acute Post-Operative Pain. Medical review was conducted in accordance with applicable statutory, regulatory, and sub-regulatory guidance.

Common Reasons for Denial

  • Medical Necessity
    • The medical record documentation contains an error not otherwise specified. The largest number of denials within the medical necessary categories were related to Chronic Pain other than Low Back Pain. The common rationale for the denials was the missing or limited re-evaluation after the trial period, missing etiology of pain, severity of pain, and prior treatment documentation.
  • No Response to the Documentation Request
    • CMS Internet-Only Manuals, Publication 100-08, Medicare Program Integrity Manual, Chapter 3, Section 3.2.3.8 requires providers/suppliers to respond to requests for documentation within 45 calendar days of the additional documentation request. The documentation was not submitted or not submitted timely.
  • Incomplete/Insufficient Documentation
    • CMS Internet-Only Manuals, Publication 100-08, Medicare Program Integrity Manual, Chapter 3, Section 3.2.3.8, 42 CFR 424.5(a)(6), Social Security Act 1833(e) outlines a service is to be considered reasonable and necessary when it is furnished in accordance with accepted standards of medical practice and sufficient supporting documentation is present within the medical record. This denial was applicable to Detailed Writtien Orders, Refill Requests, and Written Order Prior to Delivery requirements.
