Retroactive Medicaid: can a provider bill for rides taken before approval?
Retroactive eligibility lets Medicaid cover services as far back as three months before the month a person applied, if they would have qualified then. Rides in that window can be billed once coverage posts, after the provider refunds whatever the rider paid. For applications filed from January 1, 2027 onward, the window drops to one month for adults in the expansion group and two months for all other groups.

The rule today, and the change in 2027
Under 42 CFR 435.915, a state must make Medicaid effective no later than the third month before the month of application, for anyone who received covered services in that period and would have qualified had they applied then. States may start coverage on the first day of a month. That lookback applies even if the person died before the application was filed.
Section 71112 of Public Law 119-21 shortens it. The change applies to applications made on or after January 1, 2027, the first day of the first quarter after December 31, 2026.
| Application date | Adults in the expansion group | Everyone else |
|---|---|---|
| Before January 1, 2027 | Up to 3 months before the application month | Up to 3 months before the application month |
| On or after January 1, 2027 | The month before the application month | The second month before the application month |
As an example, an expansion adult who applies in March 2027 can be covered back to February 1, 2027. A disabled adult outside the expansion group who applies the same month can be covered back to January 1. If a state gives retroactive CHIP coverage, it cannot reach further back than the second month before the application either.
What CMS says about rides in that window
CMS’s transportation guide is direct: states must process and pay claims for covered services received during the retroactive period, and that includes necessary transportation, whether the state treats rides as a medical service or an administrative activity. It covers cases where the service was already paid for. The provider may first need to return the member’s money, then claim from the state. No payment is owed for a ride that cost the member nothing, such as one from family, friends, or a public agency.
Billing a past ride, step by step
- Confirm you were enrolled on the trip date. Indiana’s retroactive policy applies only if the provider was enrolled when it gave the service. Delaware requires enrollment as a fee-for-service provider to submit the claim.
- Refund the rider. Indiana requires providers to return the member’s payments right away, though a company’s normal refund routine (for example, monthly checks) is acceptable.
- Get authorization after the fact. Indiana accepts retroactive prior authorization requests up to 12 months from the date the member’s Medicaid card is issued, marked as due to retroactive eligibility. For brokered trips, Indiana sends providers to Verida for claim instructions.
- Bill the right payer. In Indiana, most retroactive months are paid through fee-for-service, even for members who later join a health plan.
- Watch the clock. Under federal rules a claim is due within a year of the trip, and each state writes its own exception for retroactive cases. Indiana, for example, accepts these claims up to one year after the eligibility award, so check your state’s timely filing limit.
Riders with a pending application
A rider waiting on a decision is a private-pay rider for now. Indiana lets a provider charge someone who lacked coverage on the trip date, provided the person was told and agreed in writing, but if retroactive coverage comes through later, the provider has to bill Medicaid and pay the member back. Keep dated receipts for every trip, and ask riders to tell you when they are approved. Medicaid redetermination causes the mirror image of this problem: coverage that ends, then comes back.
Refunds without the mess
When a rider you charged turns out to be covered, HealthRide handles full or partial refunds with the reason recorded, and each payment and refund stays matched to its trip in one ledger. See payments.
Frequently asked questions
- Is retroactive coverage available in every Medicaid program?
- No. Some programs start coverage no earlier than the application month. In Indiana, the Healthy Indiana Plan (other than HIP Maternity) and the Package C children's plan both work that way, so a trip before the month of application cannot be billed to either. Iowa's section 1115 waiver keeps retroactive months only for pregnant women, children under 19, and certain nursing facility residents.
- Must a rider who paid before approval get a refund?
- Yes, if you bill Medicaid for the trip. CMS says operating retroactive payment may require the provider to return money collected from the member before claiming. Indiana makes it mandatory: once a provider learns of retroactive eligibility, it must return the member's payments for covered services in that period and then bill the state.
- Can a ride given before the application was approved still be paid?
- It can. Indiana lets transportation providers serve applicants before eligibility is decided, with no guarantee of payment. If the member is later found eligible back to the trip date, the provider can be paid, prior authorization can be requested after the fact, and for fee-for-service members the provider asks the broker, Verida, how to submit the claim.
- Does the 2027 change apply to children?
- Yes. Starting with applications filed January 1, 2027, anyone outside the expansion adult group, children included, can be covered back to the second month before the application month. States that give retroactive CHIP coverage face the same two-month limit.
- What if the ride is past the normal filing deadline?
- Check your state's exception for retroactive cases. Indiana accepts claims more than 180 days after the service if they arrive within one year of the eligibility award, with the note "Retroactive eligibility. Please waive timely filing." Illinois allows 180 days from the date the eligibility update appears in its system, with an override request form.
