Confirm active Medicaid provider enrollment Verify that the rendering and billing entities hold active enrollment in the state Medicaid program for the service dates. Enrollment is distinct from credentialing, and requirements differ by state and by whether the claim routes to fee-for-service or a managed care organization (MCO). See provider enrollment (/resources/glossary/provider-enrollment), credentialing (/resources/glossary/credentialing), and Medicaid provider enrollment basics (/knowledge-base/medicaid-billing/medicaid-provider-enrollment-basics). Enrollment systems and pathways vary by state; confirm with the applicable state Medicaid agency (medicaid.gov). Verify beneficiary eligibility and effective dates Confirm active Medicaid eligibility for each date of service, since eligibility can be retroactive, time-limited, or category-specific. Eligibility categories vary by state. Review eligibility verification (/resources/glossary/eligibility-verification), verifying Medicaid coverage (/knowledge-base/medicaid-billing/verifying-medicaid-coverage), and Medicaid eligibility categories (/knowledge-base/medicaid-billing/medicaid-eligibility-categories). Identify coverage type: fee-for-service vs. managed care Determine whether the beneficiary is enrolled in fee-for-service (FFS) or a managed care organization (MCO), because the responsible payer, submission destination, and rules differ. See fee-for-service (/resources/glossary/fee-for-service), managed care organization (/resources/glossary/managed-care-organization), and fee-for-service vs. managed Medicaid (/knowledge-base/medicaid-billing/fee-for-service-vs-managed-medicaid). Plan assignment and rules vary by state and plan. Resolve other coverage and coordination of benefits Medicaid is generally the payer of last resort, so identify any other liable coverage and bill it first where applicable. Review coordination of benefits (/resources/glossary/coordination-of-benefits), payer of last resort (/resources/glossary/payer-of-last-resort), Medicaid third-party liability (/knowledge-base/medicaid-billing/medicaid-third-party-liability), and Medicaid as payer of last resort (/knowledge-base/medicaid-billing/medicaid-as-payer-of-last-resort). Specific rules vary by state. Address dual-eligible and crossover situations For beneficiaries covered by both Medicare and Medicaid, confirm the correct sequencing and whether the claim crosses over automatically or requires separate submission. See dual-eligible (/resources/glossary/dual-eligible), dual-eligible beneficiaries (/knowledge-base/medicaid-billing/dual-eligible-beneficiaries), and Medicaid crossover claims (/knowledge-base/medicaid-billing/medicaid-crossover-claims). Crossover handling varies by state and payer. Confirm prior authorization where required Verify that any required prior authorization is on file and that billed services match the authorized services and units. Which services require authorization varies by state and plan. Review prior authorization (/resources/glossary/prior-authorization), Medicaid prior authorization (/knowledge-base/medicaid-billing/medicaid-prior-authorization), and the prior authorization knowledge base (/knowledge-base/prior-authorization). Verify medical necessity and supporting documentation Confirm that documentation supports the medical necessity of the billed services under the applicable program policy. See medical necessity (/resources/glossary/medical-necessity). For children, additional Early and Periodic Screening, Diagnostic, and Treatment requirements may apply — review EPSDT (/resources/glossary/epsdt) and EPSDT billing (/knowledge-base/medicaid-billing/epsdt-billing). Coverage and documentation standards vary by state. Validate coding source data and claim form Ensure diagnosis and procedure information is drawn from the current, authoritative code sets maintained by their respective stewards, and that the correct claim format is used — professional (CMS-1500) or institutional (UB-04). See CMS-1500 (/resources/glossary/cms-1500) and UB-04 (/resources/glossary/ub-04). This checklist does not reproduce code descriptors; coding requirements vary by program and payer. Check the timely filing window Confirm the claim is within the applicable timely filing deadline, which varies by state Medicaid program and by managed care plan. Review timely filing (/resources/glossary/timely-filing) and Medicaid timely filing (/knowledge-base/medicaid-billing/medicaid-timely-filing). Do not assume a universal deadline; confirm the figure with the responsible payer and the state Medicaid agency (medicaid.gov). Plan for adjudication, remittance, and denial prevention Confirm the process for reading the remittance advice (ERA) and adjudication outcome, and review common denial reasons to prevent avoidable rejections. See adjudication (/resources/glossary/adjudication), remittance advice (/resources/glossary/remittance-advice), denial (/resources/glossary/denial), and common Medicaid billing denials (/knowledge-base/medicaid-billing/common-medicaid-billing-denials). Denial codes and remittance formats follow national standards, while specific edits vary by payer.
Use this checklist safely
This is a session-only educational reference and is not stored. It holds no patient records and provides no payer-specific, state-specific, or legal determinations. Medicaid is administered by states, so requirements, deadlines, and covered services vary by state and by managed care plan; confirm specifics with the applicable state Medicaid agency and payer.
