Avoid CERT No Documentation Errors
CGS is seeing a rise in "no documentation received" errors for Comprehensive Error Rate Testing (CERT) reviews by the CERT review contractor (RC). The CERT RC Â will send an Additional Documentation Request (ADR) to the provider or supplier that includes:
- A documentation list of requested information for the service or procedure they're reviewing.
- A barcode coversheet to submit on top of the requested documentation so it's easily identified and routed appropriately.
Responding to a request for medical records from any Medicare contractor is a CMS requirement as outlined in Social Security Act §1842(p)(4). The CERT RC is a separate contractor. CGS asks that you submit your documentation to them, so it doesn't delay your review. Failure to respond to your ADR will result in a claim denial and recoupment of the overpayment.
To avoid a CERT No Documentation error and recoupment of your claim payment:
- Compile and photocopy all requested documentation for the service or procedure under review.
- For lab or diagnostic tests, reach out to the referring provider. The billing provider is responsible for obtaining the medical documentation.
- Place the barcoded cover letter on top of the documentation.
- When faxing responses for multiple CERT ADR requests, send a separate fax transmission for each claim. Sending one fax for multiple claims can slow down the review process or cause a "no documentation received" error for a claim review.
Please fax your documentation to the CERT RC (804.261.8100) with the barcode sheet on top (page 1).
