Short answer
Short answer. Four layers usually matter: the at-fault driver's liability insurance answers first for your injuries, up to its limits, and your uninsured or underinsured motorist coverage can pay above that. Your MedPay, if you have it, pays medical bills regardless of fault, and health insurance pays bills under its own rules and may want repayment later.
The stack at a glance
| Layer | Whose policy | What it pays for | When it usually pays | Watch for |
|---|---|---|---|---|
| 1. Liability | The at-fault driver's | Your injuries and property damage, up to that policy's limits | At settlement or judgment, usually in one payment | Oklahoma minimums are $25,000 per person, $50,000 per accident, $25,000 property |
| 2. UM/UIM | Yours (and maybe your household's) | Your injuries when the other driver has no insurance, too little, or left the scene | After the liability layer is used up or missing | Bodily injury only. Notice rules before you accept limits |
| 3. MedPay | Yours, if you bought it | Reasonable medical expenses for you and your passengers, regardless of fault | As bills are submitted, under your policy's terms | Limits vary. Policy terms control |
| 4. Health coverage | Your health plan, Medicare or SoonerCare | Medical bills under the plan's or program's rules | As you get care | May ask to be repaid from your settlement |
The numbers on the left are the order of responsibility. They aren't the order bills get paid. Your health plan and MedPay often pay as you go, months before the liability insurer pays anything, and then the layers sort themselves out at the end.
Why the order matters to your claim
- Bills arrive before the settlement. The other driver's insurer doesn't pay your ER bill when it comes in. Using MedPay and health insurance keeps accounts out of collections while the claim is open.
- Some payers want their money back. A health plan, Medicare or SoonerCare may claim repayment from what you recover. That comes off the top, so it changes what reaches you.
- One step out of order can cost a layer. Accepting the at-fault driver's limits before handling the notice to your own UM insurer is the classic example.
Layer 1: the at-fault driver's liability insurance
This policy pays on behalf of the driver who caused the crash. For policies issued or renewed on or after April 1, 2005, Oklahoma's minimums are $25,000 for one injured person, $50,000 for everyone hurt in one accident and $25,000 for property damage (47 O.S. § 7-103(2)(b)). Drivers can buy more. Some drive with none.
Damage to your car is a separate part of the claim. See property damage and rental cars.
Layer 2: your uninsured and underinsured motorist coverage
Oklahoma auto policies include UM coverage unless the named insured rejected it in writing (36 O.S. § 3636(A), (G)). It also works as underinsured coverage: the statute counts a vehicle whose "liability limits ... are less than the amount of the claim" as uninsured (§ 3636(C)). It covers bodily injury, not your car (§ 3636(B)).
Two rules make the order matter here. Before you settle for the other driver's limits, written notice goes to your UM insurer by certified mail, and it has 60 days to respond. And the other driver's payment "shall not reduce or be a credit against" your UM limits (§ 3636(F)). See the underinsured settlement notice and uninsured and underinsured motorist claims.
Layer 3: MedPay
MedPay is optional. The Oklahoma Insurance Department lists it as an add-on and says it "pays for reasonable medical expenses if you or your passengers are injured in an automobile accident" (OID). Check your declarations page to see if you have it and how much.
If your insurer pays MedPay to you or a relative in your household, Oklahoma law says a policy term giving the insurer subrogation for that payment isn't "valid and enforceable" (36 O.S. § 6092). Passengers from other households can be treated differently.
Layer 4: health insurance, Medicare and SoonerCare
Health coverage pays your medical bills under its own rules, with your usual deductibles and copays. The catch comes later.
- Health plans often have repayment terms in the plan documents. What they can recover depends on the type of plan.
- Medicare is a secondary payer when auto or liability insurance is responsible. It can make a "conditional" payment when that insurer "has not made or cannot reasonably be expected to make payment ... promptly," and that payment is conditioned on reimbursement (42 U.S.C. § 1395y(b)(2)(B)(i)).
- SoonerCare has its own recovery rules. See medical bills after a wreck for the papers you may get and what to ask.
What to do now
- Collect the declarations page for every auto policy in your household, plus your health insurance card.
- Ask the at-fault driver's adjuster, in writing, for the policy limits.
- Give your providers your health insurance, and ask your own auto insurer whether you have MedPay.
- Keep a running list of who has paid what, and every letter asking for repayment.
- Don't sign a release until you know every layer that applies. See what to check before accepting a settlement.
How a lawyer helps with the coverage stack
Most people never need to know how these layers fit together until the day they do. A lawyer can find every policy, put the steps in the right order, handle notices and repayment claims, and make sure money that should reach you doesn't get lost between insurers.
Common questions
Should I use my health insurance after an Oklahoma City car wreck?
In many cases, yes. The other driver's insurer doesn't pay your ER bill when it comes in, so giving providers your health insurance keeps bills paid while the claim is open. Your plan may ask to be repaid from a settlement, so keep every letter it sends. Check with a lawyer if you're unsure.
Is the coverage order the order my bills get paid?
No. The layer numbers show the order of responsibility, not the order bills get paid. Your health plan and MedPay often pay as you go, months before the liability insurer pays anything, and the layers sort themselves out at the end.
Does my UM coverage pay before the at-fault driver's insurance?
Generally no. When the other driver has some insurance, UM works as the layer above their liability limits. Give your UM insurer written notice before you accept the other driver's limits.
