CMS Provider Attestation Requirement for Medicare Eligibility (270/271)

Overview

The Centers for Medicare & Medicaid Services (CMS) has updated its Eligibility Enrollment processes effective mid-May. As part of this change, providers are now required to complete a provider attestation to access Medicare eligibility data via HETS (270/271 transactions).

CMS no longer accepts third-party enrollment submissions on behalf of providers. Attestation must be completed directly by the provider organization.

What This Means

• Each provider must attest for all applicable Group NPIs (Type 2) used for Medicare eligibility
• Attestation confirms the authorized relationship with your trading partner
• Must be completed by a PECOS-enrolled authorized or delegated official
• This is now the required and fastest path to enable or maintain eligibility access

Required Information

Prepare the following before starting:

• Group NPI(s) (Type 2)
• PTAN(s) (Provider Transaction Access Number)
• Trading Partner Details
  • Sohar Health Trading Partner ID: M73T
• Authorized Signer Information
• Effective Date of Relationship (you may use today’s date)

Key Notes

• Required for each Tax ID (EIN) + Group NPI (Type 2) combination
• Rendering NPIs (individual) are not included
• Only required once per Tax ID/NPI combination, even across multiple states

How to Complete the Attestation

Step 1: Identify Your MAC Jurisdiction

You must complete attestation through your Medicare Administrative Contractor (MAC).

Common MACs include:

• Noridian (Jurisdictions E & F)
• NGS (Jurisdictions K & 6)
• Novitas (Jurisdictions H & L)
• Palmetto GBA (Jurisdictions J & M)

Step 2: Access the HETS EDI Enrollment / Attestation Portal

Provide:

• Organization (Group) NPI(s)
• PTAN(s)
• Trading Partner ID: M73T

Submit the form per your MAC’s instructions.

Step 4: Confirmation & Processing
