Medicare Eligibility (MCRUS) CMS Attestation
Action Required – Medicare Eligibility (MCRUS) CMS Attestation Update
Deadline: May 1, 2026
April 9th, 2026: Important Update – Additional Action Required
If your organization has already completed attestation, additional steps are now required to ensure continued eligibility access under the updated process.
Overview
Etactics has established a direct connection for Medicare Eligibility (270/271) transactions using Payer ID MCRUS (All States) with the Centers for Medicare & Medicaid Services.
To maintain uninterrupted access, CMS requires all providers to:
- Complete attestation with their Medicare Administrative Contractor (MAC)
- Validate each NPI used for eligibility transactions under the new workflow
What Etactics Has Completed
- Secured a direct connection with CMS for Medicare Eligibility (270/271)
- Obtained Etactics Unique ID: 6WCW
- Established MCRUS as the payer ID for all states
- Preparing to transition from our previous vendor partner in May 2026
Action Required by Your Organization
To avoid any disruption in Medicare eligibility verification services, complete all steps below:
1. Enroll in HETS EDI
All providers and suppliers must be enrolled in the HIPAA Eligibility Transaction System (HETS).
2. Complete CMS Attestation with Your MAC
- Submit attestation through your Medicare Administrative Contractor (MAC)
- Use Etactics Unique ID: 6WCW
3. NEW: Validate Each NPI (Required Even If You Already Attested)
You must now actively validate each NPI used for eligibility requests:
- From your Enrollment Dashboard, generate an Eligibility 270 Enrollment request
- Use Payer ID MCRUS
- Complete this step for each NPI currently used for eligibility inquiries
4. Submit Proof of Attestation and Validation
Each MAC provides different confirmation formats. You must:
- Attach your completed enrollment form (including final page details)
- Include any confirmation emails or screenshots
- Upload all documentation to your Enrollment ticket
- Ensure the submission reflects use of Etactics Unique ID: 6WCW
5. Complete All Steps by May 1, 2026
CMS will transition to a new HETS trading partner management system on May 11, 2026.
Failure to complete all steps before this date may result in eligibility service interruptions.
