The deadline for registering to participate in the Medicare DME MACs’ July ICD-10 testing project is Friday, April 17.

The voluntary limited end-to-end testing will take place July 20-24. Fifty participants from each DME MAC will be chosen from the group of providers who register to take part.

A March 20 bulletin from CMS said participants will be selected “to represent a broad cross-section of DMEPOS supplier types, claims types and submitter types.”

To be considered for participation, providers must fill out a form and submit it by April 17. Providers who previously participated in the January or April testing weeks are already registered for the July event and don’t have to fill out a new registration form.

Access the registration form on the CEDI Web site: ngscedi.com. Click on the ICD-10 Testing Information portion of the navigation bar.

Providers who register will be notified by May 8 regarding whether or not they will be asked to take part in the testing event.

“The CEDI and DME MAC systems will be able to accommodate future dates of service for this testing,” the bulletin said. “Test claims with ICD-10 codes must be submitted with dates of service [of] Oct. 1, 2015, through Oct. 15, 2015.”

Each participating provider will be able to submit up to 50 test claims during the testing week. The provider’s DME MAC will then process the claims and render an electronic remittance advice, which will be sent back to the provider.

Minimum provider requirements to participate in the testing week include having an active Trading Partner ID with CEDI, and submitting claims directly to CEDI currently. Testing providers will be given a new Trading Partner ID to use for the ICD-10 test.

The United States healthcare system is heading toward a big transition in the fall, when ICD-10 codes replace the current ICD-9 code sets on claims with dates of service on or after Oct. 1, 2015.
