Within a week of a collision you'll hear subrogation, policy limits, letter of protection, IME. They get used at you, quickly, by people who already know what they mean. Here they are in plain language, with the Spanish alongside, and a note on why each one actually matters to you.
Medical Payments coverage on your own auto policy. It pays your medical bills after a collision regardless of who caused it.
Why it matters: many people never use MedPay because they assume claiming on their own policy raises their rates or means admitting fault. It doesn't. It is the fastest, least complicated money available after a crash, and a lot of people pay out of pocket while it sits unused.
Coverage that pays medical costs and sometimes lost income no matter who was at fault.
Why it matters: California is not a no-fault state, so PIP is less common here than in other states. If you moved from a no-fault state, the policy you're used to may not be the policy you have.
Coverage on your policy that responds when the at-fault driver has no insurance, not enough insurance, or drove away.
Why it matters: this is the coverage that saves people in hit-and-runs, which are common in Oakland. If you were a passenger in an Uber or Lyft when it happened, note that California reduced the UM/UIM that rideshare companies must carry during the on-trip period effective January 1, 2026. Our rideshare page covers that.
An agreement where a provider treats you now and gets paid later, out of any settlement, instead of at the time of service.
Why it matters: a lien is how someone with no coverage and no money gets care after a crash. It is not free care. It is deferred payment, and you should understand what you're signing.
A letter from your attorney to a provider promising payment out of a future settlement. It is what makes lien-based treatment possible.
Why it matters: it's a promise about money, not about care. Your treatment shouldn't change because one exists, and if a provider's plan changes when one appears, that's worth noticing.
An insurer's right to be paid back out of your settlement for what it already spent on your behalf.
Why it matters: this is the one that surprises people at the end. If your health insurance paid for your care, it may have a right to reimbursement from whatever you recover. The settlement figure is rarely the amount that reaches you.
The maximum a policy will pay. Once reached, that policy pays nothing more, no matter what the real costs turn out to be.
Why it matters: California's minimum required liability coverage is low relative to what a serious injury costs. A driver can be fully at fault and still carry a policy far too small to cover what happened.
An examination arranged and paid for by an insurance company.
Why it matters: read the word "independent" carefully. That doctor is not your treating doctor and is not providing you care. It is an evaluation for the insurer, and it's reasonable to talk to a lawyer before attending one.
A California DMV form due within 10 days of any collision involving injury, death, or more than $1,000 in property damage. Filed regardless of fault, and separate from both the police report and the insurance claim.
Why it matters: nearly nobody knows about it, and missing it can put your driving privilege at risk. It's in our free Crash Kit.
The rule that being partly at fault does not automatically stop you from recovering damages.
Why it matters: people talk themselves out of getting examined because they think the crash was partly their fault. That's a legal question, not a medical one, and it has nothing to do with whether you should be looked at.
A stretch of time after a collision with no documented care.
Why it matters: this is the single most common argument used against injured people. If you felt okay for three weeks and then got worse, the record shows three weeks of nothing. That's why we push for an examination early even when you feel fine.
A written summary from a treating provider covering how the injury happened, what was found, what was done, and where things stand.
Why it matters: it's the document that gets read by people who never met you. Ours describes findings and dates. It does not argue, and it does not estimate what anything is worth.
The bundle an attorney assembles and sends to an insurer: records, bills, and the narrative report.
Why it matters: it's built from documents created weeks or months earlier. Nothing can be added retroactively, which is why what gets written down on day three matters so much.
Injury from rapid back-and-forth movement of the neck. Clinically it's called cervical acceleration-deceleration injury.
Why it matters: the word has been used dismissively for so long that people feel embarrassed saying it. The underlying injury is real, well described in the literature, and it frequently doesn't peak until 24 to 72 hours after the crash.
Damage to muscles, ligaments and tendons rather than bone.
Why it matters: it does not show up on a standard X-ray. "Nothing's broken" and "nothing's wrong" are different statements, and the emergency room is answering the first question, not the second.
How far a joint actually moves, measured in degrees.
Why it matters: this is the difference between "my neck hurts" and a measured finding recorded on a date and repeated over time. It's the most useful objective thing a treating doctor can put in your record, and it costs nothing but the time to measure it properly.
One thing this page won't do. Nothing here tells you what a claim is worth, and we won't estimate that for you at your visit either. We're your treating doctor, not an expert witness. What a case is worth is a question for a lawyer, and we don't take a fee from any of them.
Same-day appointments, seven days a week, downtown Oakland. In English or Spanish. Explaining this is free, whether or not you become a patient.
