Medicare documentation errors are the primary driver of DME claim denials and audit recoupments. They are not rare edge cases. The OIG’s 2023 DME billing compliance report found documentation deficiencies account for the majority of improper payments.<\/p>\n
CMS TPE audits specifically target HCPCS categories with known error patterns. If you bill high volumes of E0601 (CPAP), E1390 (oxygen concentrators), or K0800-series power wheelchairs, your categories receive the most scrutiny.<\/p>\n
This article gives you two things: a clear map of the ten most common errors and the audit programs that find them, and a 41-item checklist across six categories that your billing team can use on every order. An AI documentation agent can run this checklist automatically in Brightree or NikoHealth; this article is the human-readable version of that logic.<\/p>\n
Four distinct programs audit DME billing. Each has different triggers, contractors, and response requirements. Knowing which one is contacting you determines how to respond.<\/p>\n\n

A MAC selects a sample of 20 to 40 claims, reviews documentation, and provides feedback. Providers with high error rates enter additional rounds. The CMS TPE process<\/a> is documented at CMS.gov.<\/p>\n RAC audits focus on recovering overpayments. RAC contractors are paid a contingency fee on recovered funds. DME is a consistent RAC target. Power wheelchairs, oxygen equipment, and CPAP supplies have all been RAC focus categories. See OIG Medicare program integrity reports<\/a> for current focus areas.<\/p>\n Key Audit Benchmarks<\/strong><\/p>\n DME improper payment rate: elevated in CMS FY2023 CERT report; documentation deficiencies are the primary driver, per CMS.gov\/CERT.<\/p> Table of Contents<\/p>\n<\/span><\/div>\n |
