Quick answer
In many states, you can apply for Medicaid retroactively to cover medical bills incurred up to 3 months before your application. Contact your state Medicaid office to apply. If approved, Medicaid may pay for some or all of your outstanding bill.
Retroactive Medicaid Coverage
Many states allow retroactive Medicaid coverage for medical services received before you applied. This means if you received care in the past 3 months and were eligible for Medicaid at the time, you can apply now and Medicaid may pay the bill retroactively.
How To Apply
Contact your state Medicaid office or visit healthcare.gov to apply. You will need to provide proof of income, identity, and residency. Apply as soon as possible - the retroactive coverage window varies by state and may be limited.
What Happens After You Apply
If approved, Medicaid will notify the provider and apply coverage to eligible services. The provider will then rebill Medicaid for the covered portion. You may still owe a portion for services not covered by Medicaid.
