Medicare Provider Enrollment (PECOS) Services
Medicare provider enrollment services get your providers registered with Medicare through PECOS so you can bill for the Medicare patients you treat. Since 2008, Provider Enrollment Services has handled Medicare enrollment, revalidations, and reassignments in-house — from the initial CMS-855 application to ongoing revalidation — so a preventable mistake doesn't reject your file or freeze your billing. Government payers are unforgiving of errors, and we complete the application correctly the first time to help you avoid the costly rejections and delays that come with getting it wrong.
What is Medicare provider enrollment?
Medicare provider enrollment is the process of registering a provider or group with the Medicare program — typically through the PECOS system and the CMS-855 forms — so Medicare recognizes them and reimburses their claims. It also covers reassignments of benefits and the revalidations Medicare requires on a set cycle.
Why does Medicare enrollment matter?
Without an approved Medicare enrollment you cannot bill Medicare, and a rejected or lapsed file can mean weeks of frozen revenue. Medicare requires providers to revalidate their enrollment every five years (CMS), and missing that deadline can deactivate billing privileges entirely.
What is Medicare provider enrollment?
Medicare provider enrollment is how a provider or group gets on file with the Medicare program so Medicare will pay their claims. In practice, that means the PECOS system and the CMS-855 family of forms — the initial enrollment for a new provider, a reassignment of benefits to a group, a change of information when something moves, and the periodic revalidation Medicare requires to keep the record active. Each of those is its own application with its own rules, and Medicare expects them to be exact.
Why Medicare enrollment matters
Government payers leave no room for guesswork. An application with a missing signature or an inconsistent address doesn’t get a phone call — it gets rejected, and the clock starts over while your billing sits frozen. Just as costly is the deadline you don’t see coming: Medicare requires providers to revalidate every five years (CMS), and a missed revalidation can deactivate billing privileges outright. Partnering with a team that knows PECOS is how you avoid both the rejection at the front end and the lapse down the road.
How our Medicare enrollment process works
We handle Medicare from the right form to the confirmed effective date. First we pin down exactly which application you need and the correct CMS-855. We complete and submit it through PECOS with the documentation CMS requires, then respond to any development request quickly so nothing stalls. We track the file to approval, confirm your effective date, and — because the work doesn’t end at approval — we monitor your five-year revalidation so your privileges stay active. When a revalidation is due, you can also look up status on our Medicare revalidation list tool.
Who it’s for
Medicare provider enrollment services fit new providers enrolling for the first time, providers reassigning benefits to a group, practices staring down a revalidation deadline, and groups adding locations or updating PECOS records. If Medicare patients are part of your practice, keeping this enrollment clean and current is non-negotiable — and it’s exactly the kind of exacting, deadline-driven work we take off your desk.
Provider Enrollment Services is a credentialing and payer-enrollment service; approval decisions and timelines are determined by the payers and CMS, not PES.

Medicare Enrollment (PECOS) — questions, answered.
How often do I have to revalidate my Medicare enrollment?
Medicare generally requires providers to revalidate every five years, and suppliers more often (CMS). Missing the deadline can deactivate your billing privileges, so we track the date and handle the revalidation before it lapses. You can also check status on our Medicare revalidation list tool.
What is PECOS?
PECOS is Medicare's online Provider Enrollment, Chain, and Ownership System, where enrollment applications are submitted and maintained. We prepare and manage your PECOS record for you.
Does Medicare use CAQH?
Traditional Medicare enrollment runs through PECOS, not CAQH — though some Medicare Advantage (commercial) plans do rely on CAQH. We manage both paths so nothing is missed.
How long does Medicare enrollment take?
Industry sources report Medicare enrollment commonly takes about 60–90 days, within the broader 60–180 day credentialing range (Verisys, EHR Source). CMS sets the timeline and the effective date, not PES.
What happens if my Medicare enrollment is rejected?
Rejections usually stem from missing or inconsistent information. We correct and resubmit, and — more importantly — we prepare the application carefully up front to avoid the rejection in the first place.
