Medicare Enrollment for New Providers: What You Need to Know

## Why Medicare Enrollment Matters Medicare covers over 65 million Americans, making it one of the largest payer sources for most medical practices. Without Medicare enrollment, you cannot bill for services provided to Medicare beneficiaries. ## The PECOS System The Provider Enrollment, Chain, and Ownership System (PECOS) is Medicare's online enrollment portal. All new enrollment applications, revalidations, and changes must be submitted through PECOS. ### Getting Started with PECOS 1. **Create an NPPES account** if you haven't already 2. **Obtain your NPI number** (required before Medicare enrollment) 3. **Register for an Identity & Access Management (I&A) account** 4. **Link your NPI to your I&A account** 5. **Begin your enrollment application in PECOS** ## CMS-855 Forms Depending on your provider type, you'll complete one of these forms: - **CMS-855I** — Individual practitioners (physicians, NPs, PAs) - **CMS-855B** — Clinics, group practices, and organizations - **CMS-855A** — Institutional providers (hospitals, SNFs) - **CMS-855R** — Reassignment of benefits ## Required Documentation For individual provider enrollment (CMS-855I), you'll need: - Valid state medical license - Board certification (if applicable) - Malpractice insurance certificate - Practice location details (address, phone, hours) - NPI number - Social Security Number - Bank account information for EFT setup ## Timeline Expectations Medicare enrollment typically takes: - **Standard processing** — 60-90 days - **With complications** — 90-120+ days - **Revalidation** — 30-60 days ## Common Enrollment Pitfalls 1. **Incomplete applications** — Missing information triggers development letters 2. **Address discrepancies** — Practice address must match exactly across all records 3. **Expired licenses** — All credentials must be current at time of application 4. **Missing signatures** — Electronic signatures must be properly authenticated 5. **Wrong form type** — Using the incorrect CMS-855 variant ## Tips for Faster Enrollment - Ensure all state licenses are current before applying - Have all documentation ready before starting the application - Respond to development letters within 30 days - Consider hiring a credentialing specialist for complex situations - Apply for Medicare before other payers (many require Medicare enrollment first) ## How LL Billing Helps with Medicare Enrollment Our credentialing team manages the entire Medicare enrollment process, from PECOS application to final approval.
