How Medical Liens Differ From Reimbursement Claims

Medical liens are claims against your recovery by people or programs that provided or paid for your care. They come in two broad types. Some are true liens from treating providers, such as a hospital lien or a doctor who treated you on a lien.

Others are reimbursement claims from payers, such as a health plan, Medi Cal or Medicare. Each type follows its own rules, and those rules decide how much you must repay and whether the amount may shrink.

Medical Liens From Treating Providers

Some doctors and clinics treat injured people without upfront payment, in exchange for a lien on the future settlement. The provider then waits for payment from the recovery. These arrangements depend on a written agreement, so read it carefully before signing. It usually sets the rate and explains what happens if the case recovers little.

Hospitals have a separate statute. California’s Hospital Lien Act gives hospitals a lien on certain recoveries for emergency and ongoing care. After notice, a payer generally must honor that lien to the extent 50 percent of the recovery, after prior liens, can cover it. So hospital liens have a built in ceiling tied to the settlement size.

Health Plan Reimbursement

Health plans that paid for crash related care often seek repayment. For plans regulated by California, Civil Code section 3040 caps the lien. The text is on the California Legislature site. In general, the lien cannot exceed the amount the plan actually paid, and it shrinks by a share for attorney fees and costs and by the injured person’s share of fault in a judgment.

The statute also sets an outside limit. When a lawyer represents the injured person, the lien generally cannot exceed one third of the moneys due. Without a lawyer, the cap is generally one half. Those limits often reduce the repayment significantly.

Self Funded Employer Plans

Some employer plans are self funded and governed mainly by federal law. Those plans may follow their own plan language instead of Civil Code section 3040. As a result, the reimbursement rules can differ a great deal.

Ask the plan for its governing documents and a statement of what it paid. Then compare the plan’s reimbursement terms with the settlement amount, since some plans still agree to reduce their claim when asked in writing.

Medi Cal Recovery

Medi Cal can claim repayment for care it covered. California law reduces that claim by 25 percent for attorney fees when the beneficiary pays fees, and it also shares costs. The state also cannot recover more than the beneficiary’s net recovery after fees and costs. Report the claim to the Department of Health Care Services early.

Medicare Conditional Payments

Medicare may pay for crash related care while a liability claim is pending. The Centers for Medicare and Medicaid Services calls these conditional payments and expects repayment once a settlement, judgment or award occurs. A beneficiary must report the case to Medicare’s recovery contractor, which then sends a letter explaining the process.

Medicare claims need close attention, because they carry federal rules. So start the reporting process early, long before the case settles.

Workers Compensation Liens

When a work injury also involves an outside party, the employer or its insurer may claim a lien for benefits it paid. California’s Labor Code addresses that lien and how costs and fees come first in some cases. For more on that overlap, see California subrogation law.

Comparing Medical Liens and Payer Claims

  • Provider liens depend mostly on the written agreement
  • Hospital liens follow the Hospital Lien Act
  • State regulated health plans follow Civil Code section 3040
  • Self funded plans may follow federal rules and plan terms
  • Medi Cal and Medicare have their own recovery programs

Identifying the type of each claim is the first step, and the lienholder’s own letter usually says which kind it is. Then you can apply the right rule.

Disputing Medical Liens

Errors happen. A lien may include care for an unrelated condition, duplicate charges or bills from before the crash. So compare each line with your own treatment calendar.

Then send a written dispute listing each charge you challenge and why. Attach records that support your position, and ask for a corrected statement.

Requesting Final Amounts

Before settling, ask each lienholder for a written itemized statement. Check every charge against your records. Remove charges unrelated to the crash.

Then ask the lienholder to confirm in writing that the corrected figure is final, so no new charges appear after the settlement closes. Also ask whether the lienholder will accept a reduction, since many agree when the recovery stays small.

Keep every letter. For more on handling bills during the claim, see medical bills pending settlement.

Timing of Medical Liens

Lien resolution often takes longer than the settlement itself. Settlement funds may sit in a trust account while each lienholder confirms its final amount. That delay can frustrate injured people, yet it protects them from later demands. A lawyer can usually explain the expected timing for each lienholder at the start.
