One of the first worries after a crash is the medical bills. The at-fault driver's insurer usually doesn't pay bills as they come in; it typically pays once, at settlement. So in the meantime, the bills usually go through your own coverage. Here is how I explain it. This is general information, not advice about your policy.

Your health insurance

In my experience, health insurance is usually the main way treatment gets paid for while an injury claim is pending. Give your providers your health insurance information, and keep copies of the explanation-of-benefits statements. Using your health plan can also mean the bills are paid at the plan's negotiated rates.

Medical payments coverage (med-pay)

Med-pay is an optional part of many auto policies. It generally pays medical expenses for you and your passengers up to a set limit, often regardless of fault. The details depend on your policy, so read the med-pay section and your declarations page. Med-pay can help with deductibles, co-pays, and bills your health plan doesn't cover.

Two things to know:

• Your insurer may want repayment. Many policies say the insurer is repaid from your later recovery against the at-fault driver.
• It can reduce UM. Under Insurance Code section 11580.2(e), a policy may reduce your uninsured motorist recovery by med-pay amounts paid or due.

Liens and reimbursement

• Health plans. Many health plans have a right to be repaid from an injury recovery. For plans subject to California regulation, Civil Code section 3040 limits the lien. It's generally capped at what the plan actually paid providers (with a different measure for capitated care) plus the reasonable cost of perfecting the lien. If you had an attorney, the lien generally can't exceed one-third of your recovery. Self-funded employer plans and government programs can be governed by different rules.
• Hospitals. Under Civil Code section 3045.1, a hospital that treats someone injured by another's wrongful act generally has a lien on the recovery for its reasonable and necessary charges. Related sections limit and regulate those liens.
• Government programs. Programs like Medi-Cal and Medicare have their own reimbursement rights. Tell your lawyer if either paid any of your bills.

Practical tips

1. Report the accident to your auto insurer and ask whether you have med-pay and how to use it.
2. Give providers your health insurance. Avoid letting bills go straight to collections, and ask about billing holds while a claim is pending.
3. Keep every bill, receipt, and explanation of benefits in one folder.
4. Don't sign a settlement or release until you understand who has to be repaid from it.

How I can help

Sorting out who gets repaid, and how much, is part of resolving an injury case. I handle injury cases on a contingency fee: no attorney's fee unless there is a recovery. Case costs may still apply, and every case is different. No outcome is guaranteed.
