Some payors—particularly Medicare, Medicaid, and certain commercial networks—may ask you to confirm that your practice is operating as a group rather than as a collection of individual providers. This is typically done through a Group Practice Attestation or similar document.
Even if your group is small, payors may need written confirmation that you're credentialing under a Type 2 NPI and billing as an organization.
What Is a Group Practice Attestation?
A Group Practice Attestation is a brief statement confirming that your business is credentialing as a group practice, and that services are provided under the group’s legal and billing structure.
It usually includes:
A statement affirming that you operate as a group A list of current or planned providers (optional) A signature from the owner or authorized representative It may also clarify whether your providers are employees, contractors, or affiliates of the group.
Why Do Payors Ask for This?
Payors use this attestation to:
Confirm how your services will be billed (under the group vs. individually) Set up your organization correctly in their systems Avoid misclassification of provider types Comply with internal and regulatory requirements This document helps prevent claim issues and setup errors—especially when multiple providers are involved.
When Might You Be Asked for It?
You may be asked to submit a Group Practice Attestation when:
Enrolling with a new payor as a group Applying for a Type 2 NPI-based contract Working with Medicare, Medicaid, or certain behavioral health networks Credentialing a new provider under an existing group Not every payor will request it, but it's common in government programs and networks that require clear structural documentation.
Tips for Providing a Group Attestation
Use your official legal name as it appears on your W-9 and CP-575 Include your group NPI (Type 2) and Tax ID Clearly state that you operate as a group practice Keep it brief—usually 1–2 paragraphs Sign and date the statement as the authorized representative
