Medicaid Provider Enrollment Services — All 50 States

Our 6-Step Medicaid Enrollment Process

Step 1: State Program Analysis (Days 1–3) — We identify your state's specific Medicaid program structure: is it primarily fee-for-service, managed care, or a hybrid? Which MCOs operate in your service area? Does your state have separate CHIP enrollment? What taxonomy codes and provider types does the state recognize for your specialty? This mapping determines the full scope of enrollment needed.

Step 2: State Medicaid Application (Days 3–7) — We prepare and submit your state Medicaid enrollment through the correct portal (TMHP, Medi-Cal, eMedNY, FLMMIS, etc.) with all required documentation: state license, DEA, NPI, W-9, malpractice certificate, and any state-specific requirements (background check results, Medicaid-specific attestations, site visit documentation for some provider types).

Step 3: MCO Identification & Credentialing (Days 5–14) — In managed-care states (the majority), we identify every MCO operating in your service area and submit credentialing applications to each one. This is the step most providers miss: state Medicaid enrollment alone does not allow you to bill for the 70%+ of Medicaid members assigned to managed care plans. We credential with Molina, Centene, Amerigroup, WellCare, UnitedHealthcare Community Plan, and all state-specific MCOs.

Step 4: CHIP Coordination (Days 7–14) — In states where CHIP requires separate enrollment, we submit that application simultaneously. In integrated states, we verify CHIP coverage is included in your Medicaid enrollment automatically.

Step 5: Weekly Follow-Up & Deficiency Response (Weeks 2–12) — State Medicaid offices and MCOs are contacted weekly. Deficiency requests — common with Medicaid due to state-specific documentation requirements — are resolved within 48 hours to prevent processing resets.

Step 6: Activation & MCO Directory Verification (Weeks 8–16) — Upon approval, we confirm effective dates with the state and every MCO, verify your listing in each MCO's provider directory, and set up ERA/EFT for Medicaid payments. Your billing team receives a complete activation matrix showing which Medicaid products you can now bill.

Common Medicaid Enrollment Mistakes

• State-only enrollment — enrolling with the state but not MCOs; you cannot bill for managed-care members without MCO credentialing
• Wrong taxonomy code — states are strict about matching taxonomy to license type; errors cause rejection
• Missing background check — many states require fingerprint-based background checks before enrollment; not completing this stalls the application
• Ignoring revalidation — Medicaid revalidation deadlines are absolute; missing one terminates enrollment
• Not enrolling for CHIP — in states with separate CHIP, pediatric providers miss a significant patient population
• Sequential state submission — multi-state providers who enroll one state at a time lose months compared to parallel submission

Medicaid Managed Care vs Fee-for-Service — Which Are Your Patients?

The most expensive Medicaid credentialing error is enrolling with the state but not the MCOs — you are visible to 30% of Medicaid patients and invisible to 70%. ProEnrollment enrolls you with state Medicaid and every MCO in your service area simultaneously.

CHIP and D-SNP Enrollment

CHIP (Children's Health Insurance Program) covers children in households earning too much for Medicaid but unable to afford private insurance. In most states, CHIP members are enrolled in the same MCOs as Medicaid members and your MCO credentialing covers both automatically. In a handful of states (Pennsylvania, Florida, others), CHIP runs a separate program requiring its own application. ProEnrollment identifies whether your state requires separate CHIP enrollment and submits it in parallel.

D-SNP (Dual Special Needs Plans) serve the 12 million Americans dually eligible for both Medicare and Medicaid. Billing D-SNP patients correctly requires: active Medicare PECOS enrollment, credentialing with the Medicare Advantage plan offering the D-SNP product, AND enrollment with the state Medicaid program for cost-sharing coordination. ProEnrollment sequences all three so D-SNP patients are billable end-to-end.
