Where liens come from
Three main sources. Providers who treated you on a lien basis rather than billing you at the time; health insurers or public programs such as Medi-Cal and Medicare asserting a right of reimbursement for what they paid; and hospitals asserting a statutory lien for emergency and ongoing care (Civil Code § 3045.1).
All of them are paid out of the settlement before you receive your share, which is why they can turn a satisfying gross figure into a disappointing net one.
Why treating on a lien is a double-edged arrangement
It gets you treatment you could not otherwise afford, and it can help you avoid a gap in treatment, which an insurer may point to when disputing an injury. It also often produces billed amounts well above what an insurer would have paid for the same care, and those full billed figures are what the lien claims. Read the lien agreement: check whether it makes you personally responsible for any balance if the case recovers little or nothing.
This matters twice over: the billed total inflates the apparent value of your claim, and then the lien claws that inflation back out of your net.
Reduction is normal and worth pursuing
Lien holders often agree to reductions, particularly where the settlement is small relative to the treatment, or where the alternative is protracted argument. Some liens are also limited by law: many health plan liens are capped and reduced for attorney fees and costs (Civil Code § 3040), and Medi-Cal cannot recover more than you receive after attorney fees and costs (Welfare and Institutions Code § 14124.78). Where the fee is calculated on the gross recovery, every dollar taken off a lien goes to you rather than the firm — which means you should ask directly what was negotiated and what was tried.
Ask for the settlement statement
Your attorney must promptly account to you in writing for funds held on your behalf (Rules of Professional Conduct, rule 1.15(d)(4)). Ask for a statement showing the gross figure and every deduction from it, read it, and question anything you do not recognize. Use the fee calculator to see how the deductions interact.
| Source | Typically arises when | Negotiable? |
|---|---|---|
| Treating provider on lien | You had no insurance or chose lien treatment | Often, sometimes substantially |
| Private health insurer or plan | They paid for treatment and claim reimbursement | Often; for many plans the lien is capped by law and reduced for fees and costs (Civil Code § 3040). Self-funded employer plans may follow federal rules instead |
| Public benefit program | Care paid by Medi-Cal or Medicare | Governed by specific rules (Welf. & Inst. Code § 14124.70 and following; 42 U.S.C. § 1395y(b)(2)) |
| Hospital statutory lien | Emergency and ongoing hospital care after an accident | Limited. The hospital must give written notice before payment, and the lien is paid only out of 50% of the recovery after prior liens (Civil Code §§ 3045.3, 3045.4) |
Common questions
Can I just ignore a lien?
Should I use my own health insurance instead of treating on a lien?
