“How would Medicaid work behind our current plan, and could you help us decide whether to apply?”
Why I’m asking: I want to understand which treatment bills Medicaid could cover after our insurance pays.
More background and detailed requirements
How this works
This is the federal background for the same Texas benefit. The state card explains how it works.
A provider in your private insurer's network does not necessarily participate in Medicaid.
Confirm authorizations and payment arrangements before planned out-of-state care. Keep current insurance while you check.
Additional program information and published rules
Who does what
The three parts, side by side. The agency decides; nobody on this page does.
You
Give both cards to every billing office and the pharmacy, and report any insurance change to Medicaid.
Your social worker
Points you to the billing specialist who handles dual coverage and checks which oncology providers do not bill Medicaid.
The care team
Records and letters when the application asks for them.
- Who decides
- The state Medicaid agency and each provider's billing office
- Ask the billing office
- “My child has both a private plan and Medicaid. Is Medicaid registered as the secondary payer on every account, and does each provider treating my child participate in Medicaid?”
How to apply
First step: Give both cards to every billing office and pharmacy and ask them to register Medicaid as secondary.
- Keep both cards active.
- Register Medicaid as secondary with every billing office and the pharmacy.
- Ask about premium help the same month.
Where it starts: Apply for Medicaid and disclose the plan. Give both cards to every provider
What to gather
- Both insurance cards and your plan's summary of benefits
- Explanation-of-benefits statements for bills you have paid
- Names of every treating provider and the specialty pharmacy
How long: Nothing to wait for once Medicaid is active. Each provider registers the second payer the day you hand over the card.
What a yes looks like
Bills that show your plan's payment, then Medicaid's, and a patient balance of $0 on covered care.
What a no looks like, and the next move
A bill for a balance after both paid: call the Medicaid plan's coordination-of-benefits line and ask whether the provider participates.
Watch out
- Do not drop the private plan when Medicaid starts. The disability options often require you to keep it, and the network is yours.
- A doctor who takes your plan does not necessarily take Medicaid. Ask before each new provider.
- Medicaid can pay $0 on a claim your plan already paid well. The provider still cannot bill you the difference.
- For medically necessary treatment in another state, ask the plan and receiving hospital to arrange authorization and provider payment before travel. Emergency care, unsafe return travel, more available care elsewhere and customary cross-border care have federal protections.
- For qualifying American Indian or Alaska Native members, Medicaid cost-sharing exemptions depend on the regulation’s Indian-health-service conditions. Ask the Medicaid worker to check the exemption; IHS referred care has separate last-payer rules.
- An authorization decision is not the same as a completed agreement with the receiving hospital. Do not assume a pediatric provider-enrollment shortcut is already in force; have both offices confirm enrollment and payment arrangements.
The numbers and the rules
The arcane layer, kept on purpose. Checked September 10, 2026.
What it is worth
Copays and deductibles on Medicaid-covered care picked up, plus Medicaid-only extras. A participating provider takes Medicaid's payment as payment in full.
Covers: Secondary payment on Medicaid-covered care · Rides to treatment · Home nursing, equipment and personal care under EPSDT
Legal protection: A participating provider must accept Medicaid's payment as payment in full, even $0
What it costs the family: Depends on the Medicaid option.
The eligibility facts, as published
- Medicaid required
- yes
- Private insurance allowed
- yes
Decisions this site cannot make: Medicaid eligibility · Claim coordination
Expect friction on: Providers must bill both payers · A doctor who takes the plan may not take Medicaid
The trap: Dropping the private plan when Medicaid starts. The disability options often require you to keep it, and the network is yours.
What changes by state: Whether the state's children's range is open to an insured child (Georgia, Texas and California: yes) and how premium help is run.
