A PECOS certification lookup confirms whether a healthcare provider is currently enrolled in Medicare and eligible to bill the program or order and refer services for Medicare beneficiaries. The Provider Enrollment, Chain, and Ownership System is the CMS database of record for that enrollment, and federal rules require the ordering or referring provider on any Medicare claim to be enrolled in an approved status or validly opted out.1eCFR. 42 CFR 424.507 – Ordering Covered Items and Services for Medicare Beneficiaries The fastest way to check is the public CMS lookup, using the provider’s National Provider Identifier.
Why the NPI Registry Doesn’t Answer This Question
A provider can hold an active NPI and still not be enrolled in Medicare. The NPI is a 10-digit identifier assigned through the National Plan and Provider Enumeration System for administrative transactions, and every covered provider is required to have one.2Centers for Medicare & Medicaid Services. National Provider Identifier Standard (NPI) CMS states plainly that “having an NPI does not constitute Medicare enrollment eligibility”; enrollment is a separate process handled through PECOS.3HHS.gov. Help – Frequently Asked Questions (FAQs) – PECOS
The free NPPES NPI Registry is a public directory of active NPIs and nothing more.4NPPES NPI Registry. NPPES NPI Registry It won’t tell you whether a physician can generate a payable Medicare claim. PECOS will. The system covers Part A, Part B, and Durable Medical Equipment enrollment, and it feeds the Medicare fee-for-service claims payment systems directly, so a gap in PECOS translates immediately into denied claims.5CMS.

What You Need Before You Search
An NPI produces the cleanest lookup. Because the number is unique and carries no embedded location or specialty information, it returns exactly one record.6CMS. NPI Fact Sheet Without it, you can search by legal name plus city and state, though name searches often return several possibilities that need manual review.
Confirm you have the right kind of NPI for what you’re verifying. A Type 1 NPI belongs to an individual provider, and each person gets only one. A Type 2 NPI belongs to an organization such as a hospital or physician group, and organizations can hold more than one.6CMS. NPI Fact Sheet An incorporated solo practitioner may have both. When verifying a referral, use the Type 1 NPI of the individual who signed the order; when verifying the biller, use the organization’s Type 2.
How to Run the Lookup
CMS publishes a public list of providers currently eligible to order and certify items and services for Medicare beneficiaries. The Ordering and Certifying files are available for download through the CMS Data website and are linked from the PECOS homepage.7Centers for Medicare & Medicaid Services. Ordering and Certifying For an individual lookup, CMS also offers the Medicare Physician and Other Practitioner Look-up Tool, which accepts an NPI or a name search and returns enrollment information. Enter the NPI directly, or provide at least a last name and state if searching by name. The result shows the provider’s name, NPI, and current enrollment status.
These public tools are separate from the authenticated PECOS site at pecos.cms.hhs.gov, which providers and their designated staff use to submit and manage their own enrollment.8Centers for Medicare & Medicaid Services. Welcome to the Medicare Provider Enrollment, Chain, and Ownership System (PECOS) If you handle enrollment for an organization, an Authorized Official or Access Manager can request surrogate access to work on a provider’s behalf, and once approved, additional staff can be added through the My Staff tab.9NPPES. I&A Frequently Asked Questions (FAQs) For a simple certification check on someone else, though, you don’t need to log in.
Reading the Enrollment Status
The status field is the whole point of the lookup. You’ll see one of the following:
- Approved. The provider has met CMS requirements, holds a Medicare billing number, and can submit claims or order and refer services for Medicare beneficiaries. This is the only status that supports normal billing.3HHS.gov. Help – Frequently Asked Questions (FAQs) – PECOS
- Revoked. CMS has terminated the provider’s billing privileges. Claims submitted under a revoked provider’s name are denied, and the provider faces a reenrollment bar of one to ten years depending on the underlying violation.10eCFR. 42 CFR 424.535 – Revocation of Enrollment in the Medicare Program
- Deactivated. The provider is no longer active in Medicare or has ceased operations; for certified providers and suppliers, deactivation also terminates the provider agreement. Medicare will not reimburse for services furnished during the deactivation period, and the provider must submit a new enrollment application to restore billing. There’s no reenrollment bar, but the gap is not backfilled.3HHS.gov. Help – Frequently Asked Questions (FAQs) – PECOS11CMS. Revalidations (Renewing Your Enrollment)
- Opt Out. The provider has formally chosen not to participate in Medicare. Neither the provider nor the beneficiary can submit Medicare claims for services performed, and beneficiaries must sign a private contract to see the provider. An opted-out provider is nonetheless valid for the purpose of the ordering-and-referring rule, because they have made a recognized election under Medicare rules.3HHS.gov.

What a Bad Status Costs
Medicare verifies every claim against PECOS during processing. If the ordering or referring provider’s NPI is missing from PECOS, or is present but not for an eligible ordering-and-referring specialty, the claim is denied outright.1eCFR. 42 CFR 424.507 – Ordering Covered Items and Services for Medicare Beneficiaries Even a name mismatch, such as a misspelled middle name, can trigger a rejection.
For labs, imaging centers, and DME suppliers, that means rework, delayed payment, and the risk of write-offs on services already delivered. Running a certification check before accepting an order takes seconds and heads off a problem that can take weeks to unwind. If the ordering provider isn’t enrolled, the cleanest fix is to have them complete enrollment or to obtain the order from a provider already in approved status.
Bulk Verification for Credentialing Teams
If you need to verify hundreds or thousands of providers at once, the Medicare Fee-For-Service Public Provider Enrollment dataset is available for download through the CMS Provider Data Catalog in CSV format.12Centers for Medicare & Medicaid Services. Provider Data Catalog – CMS Data: About The same site hosts the Revalidation Due Date List, updated monthly, which flags providers whose enrollment is coming up for renewal.
Downloadable files are a point-in-time snapshot. A provider revoked yesterday can still appear as approved in last month’s extract. Use the bulk files for periodic audits and credentialing sweeps, but check the live lookup for any decision that turns on today’s status, such as accepting a referral or processing a claim.
Revalidation and Why an “Approved” Status Can Lapse
Medicare enrollment is not permanent. Most providers and suppliers must revalidate every five years, and DMEPOS suppliers must revalidate every three.13CMS. Provider Enrollment Revalidation Cycle 2 FAQs Contractors send notices two to three months before the due date; a provider within two months of the listed due date who has heard nothing should submit anyway rather than wait.
Miss the deadline, or fail to respond within 30 days when the Medicare Administrative Contractor asks for additional documentation, and billing privileges are deactivated.13CMS. Provider Enrollment Revalidation Cycle 2 FAQs Once deactivated, the provider files a brand-new application and receives no reimbursement for services during the gap.11CMS. Revalidations (Renewing Your Enrollment) Credentialing staff should track revalidation due dates as closely as they track license renewals, because a provider who was approved at hire can drop off Medicare quietly between reviews.
