Did You Get That Medicaid Letter Too?
Why providers are being asked to reattest — and why the Treasury Department is suddenly involved.
If you're a physician, advanced practice provider, clinic owner, or healthcare administrator, chances are you've recently received a letter from Medicare, Medicaid, or your state enrollment agency requesting that you revalidate, reattest, or update your provider enrollment information.
For many providers, the first reaction is: "Didn't I already do this?"
The second reaction is usually: "Why is the Treasury Department involved?"
The answer lies in a growing federal effort to strengthen program integrity, reduce fraud, improve ownership transparency, and ensure that taxpayer dollars are being paid to legitimate, properly enrolled healthcare providers.
What Is Revalidation and Reattestation?
Provider revalidation is the process by which Medicare and Medicaid periodically require enrolled providers to verify that their enrollment information is accurate and up to date. This includes:
- Practice locations
- Ownership information
- Managing employees
- Authorized officials
- Tax Identification Numbers (TINs)
- National Provider Identifiers (NPIs)
- Banking and payment information
- Reassignment relationships
- Organizational structure
Federal regulations have long required Medicare and Medicaid providers to revalidate their enrollment records on a recurring basis. Medicare generally requires revalidation every three to five years depending on provider type, while Medicaid providers are generally revalidated at least every five years.
Why the Increased Focus in 2026?
In 2026, CMS launched a nationwide initiative directing states to accelerate Medicaid provider revalidation efforts and place greater scrutiny on provider enrollment records. CMS specifically instructed states to develop plans to verify provider information, identify high-risk providers, and improve enrollment accuracy.
The government's concern is straightforward. Inaccurate or outdated enrollment information can create opportunities for:
- Improper payments
- Identity theft
- Shell companies
- Undisclosed ownership arrangements
- Fraudulent billing schemes
As a result, providers can expect increased requests for documentation, ownership disclosures, and enrollment verification over the next several years.
Why Is the Treasury Department Involved?
This is where many providers become confused. Historically, Medicare and Medicaid enrollment was viewed as a CMS function. Today, however, multiple federal agencies share responsibility for protecting federal healthcare dollars.
The U.S. Department of the Treasury plays a significant role because Treasury is responsible for:
- Disbursing federal payments
- Monitoring financial transactions
- Preventing improper payments
- Identifying fraud and abuse
- Supporting federal financial integrity initiatives
Federal agencies are increasingly cross-referencing provider enrollment information with Treasury databases, tax records, banking information, ownership disclosures, and federal payment systems. The goal is simple: ensure that federal healthcare payments go only to legitimate providers and organizations that are properly enrolled and accurately represented.
What Information Are They Looking For?
Providers should expect increased scrutiny in several areas:
Ownership Transparency
CMS has significantly expanded reporting requirements related to ownership, management, and controlling interests in healthcare organizations.
Banking and Payment Validation
Federal agencies want to confirm that payments are being sent to the correct entity and deposited into legitimate accounts.
NPI Verification
CMS has specifically emphasized the importance of accurate NPI information and provider identity verification.
Provider Relationships
Reassignment arrangements, group affiliations, and employment relationships are receiving greater scrutiny than ever before.
What Happens If You Ignore the Letter?
Ignoring a revalidation request can have serious consequences. Potential outcomes include:
- Payment holds
- Enrollment deactivation
- Suspension of billing privileges
- Delays in reimbursement
- Potential termination from participation programs
CMS has repeatedly emphasized that providers are responsible for maintaining current enrollment information and responding to revalidation requests by the required deadlines.
What Providers Should Do Right Now
If you've received one of these letters:
1. Don't Ignore It
Many providers assume the notice is routine and set it aside. That can become an expensive mistake.
2. Verify Deadlines
Determine whether the request is:
- Medicare revalidation
- Medicaid revalidation
- Treasury payment verification
- State enrollment update
- EDI enrollment attestation
Each may have different requirements and timelines.
3. Review Ownership Information
Make sure all ownership and controlling interest information is accurate and current.
4. Confirm Banking Information
Verify that EFT and payment information matches what is on file with CMS and Medicaid.
5. Review PECOS and State Enrollment Records
Many organizations discover outdated information that has remained unchanged for years.
6. Coordinate With Credentialing and Revenue Cycle Teams
Enrollment issues often become reimbursement problems before providers realize there is a problem.
The Bottom Line
The recent wave of Medicare and Medicaid reattestation and revalidation requests is not simply administrative paperwork. It is part of a broader federal initiative focused on program integrity, ownership transparency, payment accuracy, and fraud prevention.
The involvement of the Treasury Department reflects a growing effort to connect provider enrollment data with federal payment systems and financial oversight programs.
For providers, the message is clear: make sure your enrollment information is accurate, current, and complete before the government asks you to prove it.
Because in today's healthcare environment, protecting your reimbursement starts long before a claim is ever submitted.
