How Our Payer Enrollment Process Works
Which Enrollment Do You Need?
Medicare (PECOS/CMS-855): You’ll usually need PECOS access and the correct CMS-855 form (855I/855B/855S). We handle submission, follow-ups, and MAC coordination. Timeline: 30-90 days. Medicaid (state portal): Medicaid enrollment is state-specific. You’ll navigate state portals and screening steps. We handle state-specific requirements and resubmissions. Timeline: 45-120 days. Commercial payers (Aetna/BCBS/Cigna/UHC): Commercial payers rely on CAQH plus payer portals. We manage enrollment plus EFT/ERA/EDI setup so you can bill on day one. Timeline: 14-60 days.1

Payers & Networks
PECOS & Medicare Explained
CMS-855 Forms: Quick Reference
CMS-855I
Individual Practitioners
Solo providers billing independently with a personal NPI and EIN. Requires license, DEA, W-9, photo ID, and malpractice attestation. Typically 30-60 days to approval.
CMS-855B
Group Practices
Group practices with two or more providers under a shared group NPI. Requires articles of incorporation, ownership affidavits, all provider licenses, and EIN verification. Typically 45-90 days.
CMS-855S
DMEPOS Suppliers & Billing Locations
Employed physicians, therapists in large clinics, and DME suppliers billing through a group structure. Approval varies: 30-75 days. Read our 855S guide.
CMS-855O
Ordering & Referring Providers
Ordering and referring providers who do not bill Medicare directly but still must be registered in PECOS. Required even if you are not submitting claims yourself.
Important Note
A solo physician who also owns a group practice may need both an 855I and an 855B depending on billing structure. Submitting the wrong form results in rejection. We match you to the correct type during intake. See our 855I vs 855B vs 855S comparison guide for detailed examples.Medicare Revalidations

We coordinate across state portals to prevent one state’s delays from affecting others. Read our Medicaid enrollment by state guide for state-specific timelines and contact information.

Enrollment + EFT/ERA/EDI Setup
Medicare (CMS-855): 30-90 days from submission to approval, depending on completeness and CMS volume. Incomplete applications or requests for additional information extend timelines by 30-60 days.
Medicaid (state-specific): 45-120 days. State Medicaid programs have longer review cycles than Medicare. Some states require additional background checks or licensing verification that adds weeks.
Commercial payers (Aetna, Cigna, BCBS, UHC, Humana, Anthem): 14-60 days. Smaller payers move faster; large national carriers have longer queues. Some require credentialing before enrollment approval, which adds time.
Total time to billing-ready: 90-180 days across all payers, assuming no rejections or missing documents. With corrections or resubmissions, expect 180-270 days.
- EDI enrollment establishes the electronic connection between your practice management system and each payer through your clearinghouse. Without it, claims cannot transmit.
- ERA enrollment delivers digital remittance data directly to your billing system, eliminating manual payment posting from paper EOBs.
- EFT enrollment sets up direct deposit of insurance payments so you are not waiting on paper checks to clear.
Network Participation and Directory Listing Verification
Coverage Areas
Enrollment Status Checks
Medicare (PECOS) Statuses
- Application received - Your CMS-855 form arrived and is under review.
- Additional info requested - CMS needs clarification or missing documents before proceeding.
- Pending - Your application is in queue for final review.
- Approved - You’re in-network and effective as of a specific date.
- Rejected - Application was denied; you’ll receive a reason and can reapply.
Medicaid Statuses
- Submitted - Application is in the state portal.
- Under review - State is verifying credentials, licensing, and compliance.
- Conditional approval - Approved pending final documentation or background clearance.
- Active - You’re enrolled and can bill.
- Terminated - Enrollment ended; reapplication may be required.
Commercial Payer Statuses
- In progress - Application submitted and pending underwriting.
- Additional info needed - Payer is requesting documents or clarifications.
- Approved - Network acceptance confirmed; effective date assigned.
- Contracted - You’re live and can submit claims.
- Denied - Application rejected; appeal options may apply.
Important Distinction
Status doesn’t mean you’re ready to bill. Approval plus EFT/ERA/EDI setup plus directory verification equals billing readiness. Many providers miss this distinction and lose revenue waiting for claims to process.What You Can Do If You're Stuck
- Log into the payer portal. Check for uploaded messages, missing attachments, or form errors you can correct yourself.
- Identify the specific request. Payers usually list exactly what’s missing (e.g., “NPI verification letter,” “updated W-9,” “ownership documentation”).
- Gather and submit corrected documents. Resubmit within the payer’s stated deadline, usually 30 days.
- Follow up in writing. Email the payer’s provider enrollment team with your application reference number and confirmation of resubmission. Keep a record.

Yes. PECOS (Provider Enrollment, Chains, and Ownership System) is the mandatory system for Medicare enrollment. You must create a PECOS account, submit your CMS-855 form through PECOS, and track your status in PECOS.
However, most providers don't interact with PECOS directly. Your enrollment partner logs into PECOS on your behalf, submits your application, monitors your status, and responds to CMS requests. You still need a valid PECOS account and authorized signer credentials, but the day-to-day management is handled.
The CMS-855 is the official Medicare Provider Enrollment Application. CMS requires it to add you to Medicare and assign you a provider number. The form has three main versions depending on your practice structure:
CMS-855I: Individual provider (solo practitioner with personal NPI and EIN).
CMS-855B: Group practice (two or more providers, shared group NPI, group EIN).
CMS-855S: Individual provider within a group (you have your own NPI but bill through a larger practice structure).
Submitting the wrong form gets your application rejected. We match you to the correct CMS-855 type during intake based on your business structure.
All providers need: Valid medical, nursing, or therapy license; DEA registration (if applicable); NPI certificate; W-9 form; malpractice insurance declaration; government-issued photo ID.
Group practices also need: Articles of incorporation or LLC operating agreement; EIN verification; ownership affidavits (all owners over 20%); proof of practice location (lease or deed).
State Medicaid may additionally request: Background check authorization; child support verification (state-specific); exclusion list checks (OIG, SAM); state-specific credentialing forms.
Yes. If you're licensed and credentialed in multiple states, we enroll you in Medicare, Medicaid, and commercial payers across all of them.
Each state has its own Medicaid program with separate enrollment requirements. Medicare enrollment is national once approved, but you designate practice locations by state in your PECOS profile. Commercial payers operate differently in each state, so you'll need separate network applications with each insurer in each state.
CAQH (Council for Affordable Quality Healthcare) is a credential registry that most payers, Medicare, and Medicaid use to verify your licenses, DEA, NPI, and malpractice history. It's not technically required, but most payers reference it automatically, and keeping it current speeds enrollment across all payers.
CAQH is free to create and maintain. Once you build your profile, updating it in CAQH often automatically updates your data with connected payers.
No. Revalidation is a renewal process (Medicare does this every 5 years) where you confirm your existing information is still accurate. Re-enrollment would be applying as new, for example if you're adding a new location or changing entity structure.
We track your revalidation due dates and manage the process to avoid billing interruptions.
