The Centers for Medicare and Medicaid Services (CMS) maintains an online platform called the Provider Enrollment, Chain, and Ownership System (PECOS). Enrollment within this web-based system allows providers and suppliers to electronically onboard with Medicare and remotely manage all federally required information.
This process supports streamlined Medicare enrollments while simplifying ongoing tasks like revalidation, information updates, and status tracking. In this guide, we’ll examine how the platform compares to other well-known provider systems that are used for enabling health plan payer participation. We’ll also answer key questions about who can access PECOS and how its online Medicare enrollment process works.
With a better understanding of this federally managed platform, you can optimize your interactions with the Medicare system and strengthen overall compliance.
An Online Resource for Medicare: PECOS
An early version of PECOS was available for provider use beginning in 2009. The opportunity for digital enrollments and information tracking meant that providers (physician and non-physician) could more easily:
- Enroll with Medicare or make a change in their information.
- View their information (including any reassignment-related data).
- Verify their personal or enrollment details.
A little more than a year later, it became available as a resource for suppliers of durable medical equipment, prosthetics, orthotics, and supplies (DMEPOS). This allowed Medicare-participating DMEPOS suppliers to enjoy the same streamlined enrollment process and simplified accessibility as Medicare-enrolled physicians and non-physician providers (NPPs).
PECOS vs. NPPES vs. CAQH
These three systems are interconnected in supporting provider enrollment and credentialing. However, each serves a distinct role within those related healthcare administrative processes.
PECOS vs. NPPES
The National Plan and Provider Enumeration System (NPPES) assigns National Provider Identifiers (NPIs), which are unique 10-digit codes used for billing and healthcare transaction purposes. Like PECOS, these identifiers are managed by CMS, but PECOS is used exclusively for Medicare enrollment and billing eligibility purposes.
In other words, NPPES assigns the identifiers that confirm provider identities, while PECOS hosts the information that determines whether they’re allowed to bill Medicare.
PECOS vs. CAQH
The Council for Affordable Quality Healthcare (CAQH) is a nonprofit organization that maintains a provider data platform. This single point of entry for provider information helps streamline commercial health plan enrollments.
Medicare doesn’t rely on CAQH for enrollment or credentialing. Instead, it uses PECOS as its centralized system for Medicare provider, supplier, and participation information.
PECOS Enrollment: FAQ
Want to learn more about this CMS-managed platform or curious about whether there’s a PECOS lookup (by NPI or provider name)?
The latter question’s answer is largely no. Some PECOS search options exist, though they primarily route to public NPI provider details. To confirm active Medicare enrollment, patients are better off using Medicare’s Care Compare search. For the former question, we’ll address it comprehensively by answering a range of common PECOS questions below, explaining who can enroll, how the process works, and why it matters for Medicare participation.
What is PECOS’s primary purpose?
The Provider Enrollment, Chain, and Ownership System was largely created to modernize and streamline Medicare enrollments and their management. It provides a secure, online platform for completing essential enrollment-related tasks, including:
- Submitting applications for Medicare enrollment.
- Verifying enrollment information accuracy.
- Maintaining and updating enrollment information.
- Completing revalidation to maintain federal billing privileges.
- Tracking application and enrollment statuses.
- Withdrawing from Medicare enrollment (voluntarily).
Is PECOS Medicare specific?
Yes, PECOS is exclusively used for Medicare enrollments and information management among participating providers and suppliers. It’s not used for commercial health plan enrollment.
Who qualifies for a PECOS provider login?
PECOS logins are available to Medicare providers (like physicians, nurse practitioners, or physician assistants) and suppliers, in addition to other authorized users. These include:
- Medical groups and practices.
- Healthcare facilities, including hospitals and home health agencies.
- Administrative and credentialing staff who handle provider enrollments.
Is there a PECOS certification process that enables participation?
There’s no formal PECOS certification process. Instead, the system relies on several validation options to ensure only allowable users can create a PECOS login. For example, the NPPES logins are linked to the PECOS system, allowing access to the portal for users with NPI-related login credentials.
Individuals or practices without that shared NPPES entry point will need to register with the Identity and Access System, or the PECOS I&A. This limits access to only authorized users, helping CMS verify PECOS enrollment‘s security and integrity.
What’s the PECOS enrollment process for Medicare participation?
Medicare enrollments through PECOS can take half the time of a paper-based application, sometimes requiring as little as 15 days. There are five main steps to enrolling with Medicare using your PECOS login or online account:
- Obtain an NPI: Physicians, NPPs, and other Part-B Suppliers must have an NPI in order to enroll with Medicare.
- Register in the I&A System: An I&A System password is required to access PECOS.
- Provide the required enrollment data: Using PECOS, all information (such as name, NPI, tax ID number, and enrollment state) can be delivered digitally.
- Submit your application: Once your data entry is confirmed accurate and complete, submit the application. This locks the process until a Medicare Administrative Contractor (MAC) requests updates or corrections.
- Track status and revise as needed: If your MAC requests additional information, deliver the supplementation within 30 days of notification to avoid further delays. Continue to access PECOS to verify the status of your enrollment application until it’s been approved.
Do PECOS accounts require ongoing renewal to stay active?
The PECOS accounts themselves don’t require ongoing renewal. However, to maintain federal billing privileges, PECOS users must complete the mandatory periodic Medicare revalidations. These typically occur every five years for providers and every three years for DMEPOS suppliers. Failure to meet those deadlines may result in revoked billing privileges, risking payment delays and revenue cycle disruptions.
It’s also worth noting that PECOS passwords expire every 60 days. To maintain active accounts, users should log in regularly to ensure information remains both accessible and up-to-date.
How does PECOS benefit providers, suppliers, and health systems?
PECOS benefits providers, their patients, and the associated healthcare practice in many ways. Some of the primary advantages include:
- Faster enrollment times, helping providers begin serving Medicare patients sooner.
- Paperless processing, offering secure consolidation of enrollment data and documentation.
- Tailored applications, which help avoid unnecessary work through targeted workflows.
- Greater transparency and control, offering real-time access to application statuses and communication.
- Convenient update tracking and revalidation, making it easier to maintain active, compliant enrollment status.
- Decreased administrative burden and costs through centralized, streamlined enrollment processes.
- Better regulatory compliance by ensuring the regular review of provider and enrollment data, mitigating the risks for fraud, waste, and abuse.
