Molina Healthcare: Timely Filing, Appeals, and Billing Guide
Molina Healthcare is a managed-care organization focused on government programs — Medicaid, Medicare Advantage (including dual-eligible plans), and ACA marketplace coverage — operating in roughly 20 states. Because its Medicaid business runs under state contracts, timely-filing limits vary by state and plan, commonly 90 to 365 days; confirm the window in the state provider manual.

What is Molina Healthcare?
Molina Healthcare is a managed-care organization built almost entirely around government programs: Medicaid managed care, Medicare Advantage (heavily dual-eligible), and ACA marketplace plans. It operates in roughly 20 states, growing through acquisitions of state Medicaid plans, so like Centene it is a collection of state operations under one corporate name.
Its member population skews low-income and dual-eligible, which shapes the billing: coordination of benefits and Medicaid payer-of-last-resort rules dominate.
What are Molina\'s timely filing and appeal deadlines?
Medicaid filing follows each state's contract; MA and marketplace follow product rules. Windows commonly range from 90 days to 12 months, and appeal windows are frequently shorter than commercial payers.
How do you bill Molina dual-eligible members?
For D-SNP and dual members, Medicare (or the Medicare Advantage plan) is primary and Molina's Medicaid benefit is secondary. Bill the primary first, post the determination, then submit to Molina with that coordination-of-benefits information. Molina, as the Medicaid side, often covers cost-sharing rather than the full allowed amount.
Submit through your clearinghouse to the state-specific Molina payer ID.
What billing quirks should you watch?
- Dual-eligible focus. Medicare-first COB is routine, not an exception.
- State-contract driven. Deadlines and payer IDs differ by state plan.
- Short appeal windows. Often tighter than commercial — act fast.
- Compare with Centene. Same government-program MCO model, different states and brands.
Frequently asked questions
It varies by state and plan. Molina's Medicaid plans run under individual state contracts, each with its own filing window (commonly 90 days to 12 months), while its Medicare Advantage and marketplace products follow their own product rules. There is no single Molina number — confirm the filing window in the provider manual for the specific state and plan.
Molina is a large player in dual-eligible special-needs plans (D-SNPs) that cover members with both Medicare and Medicaid. For these members, Medicare pays first and Molina's Medicaid benefit wraps around it — so coordination of benefits is central. Bill Medicare (or the MA plan) first, then submit to Molina with the primary determination attached.
Molina uses Availity in many markets plus its own provider portal, with payer IDs that differ by state. Identify the state plan from the member card, then use that plan's provider manual for the payer ID, portal, appeal deadline, and mailing address. Molina's appeal windows are often shorter than commercial payers, so act promptly.
