If you were hurt in a car accident in Santa Clarita and treated at Henry Mayo or Facey, the value of your case comes from five things. The amounts your medical providers were actually paid or are still owed, not the amounts on the bills. How long you treated and whether there were gaps. What the exams and the imaging found. What share of the fault lands on you. And how much insurance exists on both sides of the crash. Whether you treated at Henry Mayo Newhall Hospital or at Facey Medical Group does not change the value by itself. What the records say, and what was paid, does.
The part that surprises most people is the Howell rule, named for the California Supreme Court case that set it. A night in the Henry Mayo emergency room with a CT scan and X-rays might be billed at $11,000. If your health plan paid $2,600 under its negotiated rate and you owed a $250 copay, your medical damages for that visit are $2,850, not $11,000. California limits medical damages to what was actually paid or is still owed. Insurance companies start their valuation from the paid figures, so the number on the hospital bill is not the number anyone is negotiating over, and that one rule explains why two people with the same injury and the same hospital can have very different cases.
How is a car accident case valued in California?
The value is built from the paid medical expenses, the lost wages, future care if a doctor documents it, and non-economic damages for pain and for the limits on your daily life. That total is reduced by your percentage of fault. The result is then capped in practice by the other driver’s policy limits plus any underinsured motorist coverage you carry on your own policy.
Howell: the paid amount, not the number on the bill
Medical damages in California are measured by what the provider accepted as payment, or what is still owed. For a Santa Clarita client with employer health insurance, the Henry Mayo emergency visit, the follow up with a Facey primary care doctor, the orthopedic referral and the physical therapy will all be paid at negotiated rates that are a fraction of the billed charges. With Medi-Cal the paid amounts are lower still. The health plan or Medi-Cal then asserts a right to be repaid out of the settlement, which the lawyer negotiates down at the end.
Treatment on a lien works differently. If you have no health insurance and a provider agrees to treat you and wait for payment from the settlement, the full charge is owed, so the full charge is the claimed medical expense. The insurance company will then argue that the charges are above market and try to discount them. Either way, the lawyer needs the itemized bills and the payment ledgers from every provider, because the question of what was paid against what was billed is argued line by line.
Treatment duration and what the diagnostics show
Two cases with the same emergency visit can end up far apart because of what happens over the following months. Take a Canyon Country driver rear ended on Soledad Canyon Road, seen at Henry Mayo, X-rays negative, six weeks of physical therapy through Facey, discharged with full range of motion. Now take a Valencia driver in a similar crash on McBean Parkway with the same emergency visit, but pain radiating into the arm by the third week, an MRI showing a disc herniation pressing on a nerve root, an epidural injection, and a surgical consult in the fifth month. The second case is worth far more than the first, not because the crash was worse, but because the findings are objective and the treatment is longer and more invasive.
Gaps cut the other way. A person who stops treating for two months and then returns hands the insurance company an argument that the injury had resolved and something else caused the symptoms to return. Prior findings matter too. An MRI on a fifty five year old will usually show some degeneration, and the insurance company will say the disc was already damaged. California allows recovery for the aggravation of a pre-existing condition, so the answer is the Facey chart from before the crash showing no complaints for that part of the body, and the doctor’s note tying the new symptoms to the collision.
Your share of the fault
California is a pure comparative negligence state, which means every dollar of damages is reduced by your share of the fault. A rear end collision at a stop on Bouquet Canyon Road is usually entirely the other driver’s fault. A left turn at Newhall Ranch Road against a driver who was speeding might be assigned seventy percent to the other driver and thirty percent to you, and that thirty percent comes off everything, medical expenses included. The insurance company will also raise seatbelt use if the records say you were unbelted, as fault for the injuries a belt would have prevented. The Sheriff’s report from the Santa Clarita Valley station, or the CHP report for a freeway crash, is evidence on this question, not a ruling.
Policy limits and UM/UIM: the ceiling on the case
The most common reason a Santa Clarita case is worth less than the injury deserves is the insurance. The minimum liability policy in California under Vehicle Code section 16056 is $30,000 per person and $60,000 per accident. Take a Saugus driver with $24,000 in paid medical expenses, a herniated disc and an injection, hit by a driver carrying the minimum. The other driver’s policy pays its $30,000 and no more unless that driver has personal assets worth pursuing, which is rare. The next layer is the injured driver’s own underinsured motorist coverage under Insurance Code section 11580.2. With $100,000 in underinsured motorist coverage, her own insurance company pays up to $70,000 above the other driver’s $30,000. With none, the case stops at $30,000.
The ceiling moves up when the other vehicle was commercial. A delivery van or a tractor trailer on the 5 near Castaic usually carries a commercial policy, and interstate carriers must carry at least $750,000. A rideshare driver with a passenger, or on the way to pick one up, is covered by a $1 million policy. The lawyer identifies every policy early, because the valuation means nothing until the ceiling is known. One more limit applies. If you were driving your own uninsured car, Civil Code section 3333.4, which came from Proposition 213, bars non-economic damages even when the other driver was entirely at fault. Medical expenses and lost wages can still be recovered.
What the insurance company will argue about the Henry Mayo and Facey records
The adjuster reads the emergency chart for phrases such as no acute findings, ambulatory, and pain three out of ten, and quotes them as proof that the injury was minor. The discharge instructions that say to follow up with primary care in three to five days become a problem if the first Facey visit was three weeks later. A note that says the patient is improving at the fourth week is used to argue that you were healed at the fourth week, even if the next note says the pain returned. The insurance company will also request prior records for the same part of the body, and a Facey visit for back pain two years earlier will become the center of its position. None of these arguments ends a case, but each has to be answered with the full record.
What to do now if you are still treating
Keep every appointment and tell the doctor about every symptom, including the ones that seem minor. Ask for copies of the emergency discharge papers and any imaging reports. Send your lawyer your auto policy declarations page so the uninsured and underinsured motorist question is answered early. Do not accept an offer while you are still treating, because the value cannot be known until the treatment ends or a doctor says the condition is permanent. Keep a record of the days missed from work, with pay stubs, because lost wages are proven with documents.
Questions people ask next
Does it matter that I went to Henry Mayo instead of a doctor who works on liens?
No. Where you treat does not change the value. The findings, the duration and the paid amounts do, and an emergency visit the night of the crash is one of the strongest pieces of evidence that the injury is real.
Will my health insurance want money back from the settlement?
Yes. Health plans, Medi-Cal and Medicare each have a right to be repaid from the recovery. The lawyer negotiates those amounts down before the settlement is distributed.
When will I know what my case is worth?
When treatment ends or levels off, the records and ledgers are in, and every policy has been identified. That is when the demand goes out, and it is usually several months after the crash.
