California's Required Medical Protection in Auto Insurance
In California, the law does not mandate MedPay or Personal Injury Protection the way some no-fault states do. Instead, the state sets minimum liability limits that indirectly shape how injury costs are covered after a crash. Because California follows a fault system, the at-fault driver's liability coverage pays for others' medical expenses, while your own policy steps in only under specific conditions. Understanding which layer activates first can prevent surprise bills when an accident report is still open.

Sofia Martínez explains the interplay of California's required coverages, optional add-ons, and the limits that matter most when medical costs mount after a collision.
What the State Minimums Cover — and What They Do Not
California's Financial Responsibility Law requires drivers to carry liability insurance with these minimum limits:
- Bodily injury liability: $15,000 per person, $30,000 per accident
- Property damage liability: $5,000 per accident
- Uninsured motorist bodily injury: $15,000 per person, $30,000 per accident
- Uninsured motorist property damage: $3,500 per accident
These limits are the floor, not the ceiling. The uninsured motorist portion can cover your own medical treatment if the other driver has no insurance or hits you and flees, but only up to those sub-limits. For serious injuries, the minimums are often far below the cost of hospitalization, surgery, or rehabilitation.
How Medical Costs Get Paid After a California Crash
When an accident occurs in California, payment typically follows a sequence tied to fault and policy structure:
| Coverage Layer | Pays For | Key Condition |
|---|---|---|
| Your liability coverage | Other driver's medical bills when you are at fault | Your per-person and per-accident limits apply |
| Other driver's liability coverage | Your medical bills when they are at fault | Subject to their limits, not yours |
| Uninsured/underinsured motorist (UM/UIM) | Your injuries when the other driver lacks coverage | Must be included or rejected in writing in CA |
| MedPay / PIP (optional) | Your medical bills regardless of fault | Only if added to your policy |
| Health insurance | Remaining bills after auto coverage is exhausted | May seek reimbursement from any settlement |
Because California is a tort state, your own injury costs are not paid by a mandatory no-fault layer. Optional MedPay or PIP can fill that gap, but insurers must offer UM/UIM alongside liability, and you must reject it in writing if you decline.
Why the Minimums Often Fall Short
A single hospital stay for a crash-related injury can exceed the $15,000 per-person liability limit. When bills surpass those limits, your health insurance typically picks up the remainder — but only after the auto settlement or court judgment is resolved. In California, health insurers may exercise subrogation rights, meaning they can seek repayment from any recovery you receive from the at-fault party.
Choosing Limits That Reflect California's Cost of Care
Given the state's high medical costs and litigation environment, Sofia Martínez recommends reviewing liability and UM/UIM limits annually. Higher bodily injury limits protect your assets if you are sued, while stacked UM/UIM coverage can help when an underinsured driver causes your injuries. California allows you to select split limits or a single combined single limit, and the right choice depends on your risk exposure, driving frequency, and financial ability to absorb costs above the minimums.
