In short

Providers in Medicaid must take Medicaid's payment as full payment.
You can still owe a copay the plan sets.
Being unable to pay a copay does not wipe it out.

What this means

The federal rule for Medicaid says the state may only let providers in its program who take Medicaid's payment as payment in full. That payment is what the Medicaid agency pays plus any deductible, coinsurance or copay the plan requires you to pay [1]. So a provider in the program can't bill you for the rest of the charge [1].

You can still owe a copay that the plan requires. The rule also says that being unable to pay does not erase what you owe for that cost sharing [1]. The sources here do not cover bills from a provider that is not in Medicaid.

Your next step

Look at the bill and your Medicaid notice. Ask the billing office in writing to show what Medicaid paid and what copay they think you owe. The sources give no deadline.

Check it yourself

Your state Medicaid agency tells you which copays apply. If you got care from a provider outside Medicaid, the rule above may not apply — "Don't know yet".

Where this comes from (1)

[1] GovInfo · 42 CFR 447.15 Acceptance of State payment as payment in full · § 447.15 · checked 2026-11-06
must limit participation in the Medicaid program to providers who accept, as payment in full, the amounts paid by the agency plus any deductible, coinsurance or copayment required by the plan to be paid by the individual … An individual's inability to pay does not eliminate his or her liability for the cost sharing charge
