A client walks in with a shattered ankle from a grocery-store fall. She has coverage through her own employer, she is also a dependent on her husband's plan, and because her hours were cut last year she picked up Medi-Cal as a backstop. Three cards in the wallet, $84,000 in charged medical bills, and a case that may top out at a $100,000 policy limit. Now three payers each want to be made whole out of the same recovery.
The instinct is to treat this as three liens stacked on top of each other. It is not. Coordination of benefits is a set of ordering rules that decides which plan pays first, which pays the balance, and — this is the part that matters at settlement — which one actually has a reimbursement claim against your client's tort recovery and how far that claim can reach. Read the order wrong and you will either double-count what you owe back or wave through a demand from a plan that paid nothing.
Order of payment is not order of reimbursement
Start by separating two questions that plaintiff lawyers routinely blur. The first is which health plan was primary for paying the medical bills as they came due. The second is which payer has a recovery claim against the third-party settlement. A plan can be primary for one and silent on the other.
Order of payment between two private group plans follows the coordination-of-benefits provisions written into the policies, which track the NAIC model that California carriers adopt. The employee's own plan is primary over a plan on which she is only a dependent. Between two plans covering the same child, the parent whose birthday falls earlier in the calendar year is primary — the birthday rule, not the older-parent rule. A plan covering someone as an active employee is primary over one covering the same person as a laid-off or retired worker. The secondary plan pays the difference between what the primary paid and the plan's own allowable amount, up to but not beyond the total charge. Two plans do not add up to 200% of coverage; coordination exists precisely to stop that.
Government payers sit outside those private provisions and have their own place in line. Medi-Cal is the payer of last resort by statute (Welf. & Inst. Code § 14124.90), so it pays only after private coverage is exhausted. Medicare is a secondary payer to any group health plan and to the liability settlement itself under 42 U.S.C. § 1395y(b). The practical effect is that the same $84,000 gets paid down by the primary plan first, mopped up by the secondary, and only the residue touches the public programs — which shrinks their reimbursement claims accordingly.
Only the payer that actually paid has a claim
This sounds obvious and is constantly ignored. A reimbursement or subrogation right attaches to benefits the plan paid, not to benefits it was eligible to pay. If the husband's plan was secondary and paid $6,000 as the balance after the primary's $40,000 contractual payment, its recovery interest is $6,000, not a share of the whole bill. Get an itemized payment ledger from each payer before you concede anything. I have seen a secondary plan's third-party recovery vendor send a demand built off the gross charges its member submitted, with no adjustment for the fact that the primary carrier had already paid most of it.
The number that anchors every one of these claims is the amount actually paid, not the amount billed. Under Howell v. Hamilton Meats & Provisions, Inc. (2011) 52 Cal.4th 541, a plaintiff's recoverable medical damages are capped at the sums accepted by the providers, not the higher chargemaster figures. The $84,000 in charges is a fiction once the plans applied their contract rates. That reality both limits your damages presentation and shrinks the pool any plan can claim from. When a hospital tries to escape those contract rates by asserting a lien on the recovery instead of billing the plan, that is a separate fight — see our discussion of the hospital bill write-down and what it does to the lien.
California's reimbursement caps do real work
For health care service plans and disability insurers governed by state law, Civil Code § 3040 is the statute to have open on your desk. It caps a plan's reimbursement out of a tort recovery in several ways at once. The reimbursement is reduced by a proportionate share of the attorney's fees and costs the plaintiff incurred to create the recovery — the common-fund principle written into statute. It is reduced further where the plaintiff was not made whole, and the plan's recovery cannot exceed a set percentage of the plaintiff's total recovery after those adjustments. In the classic three-payer scenario, applying § 3040 to each state-regulated plan independently often cuts the aggregate reimbursement demand by a third or more before you ever open a negotiation.
Section 3040 also bars a plan from recovering against the portion of the settlement allocated to pain and suffering or to losses the plan did not cover. That allocation is worth building into the settlement record. A clean apportionment between medical specials and general damages gives you a documented basis to tell each payer its claim reaches only the medical-expense slice.
ERISA self-funded plans break the pattern
Here is where the tidy state-law framework can collapse. A self-funded employer plan governed by ERISA is not bound by Civil Code § 3040, the made-whole doctrine, or California's common-fund rule if the plan document says otherwise. Under US Airways, Inc. v. McCutchen (2013) 569 U.S. 88, the written plan terms control an ERISA reimbursement claim; equitable defenses like made-whole and the common fund are only default gap-fillers that a clearly drafted plan can override. A well-drafted self-funded plan can demand first-dollar reimbursement with no reduction for your fees.
So the threshold move with any employer plan is to determine whether it is self-funded or fully insured. Request the plan document and the summary plan description, and look at whether claims are paid from employer assets or through an insurance contract. A fully insured plan, even one administered by a national carrier, is regulated by the state and § 3040 applies. Only genuinely self-funded plans get the ERISA override, and even then McCutchen requires the plan language to actually say so — silence still lets the equitable defaults back in. The analysis runs parallel for federal-employee plans, where FEHBA preemption under Coventry Health Care of Missouri v. Nevils (2017) 581 U.S. 87 can likewise displace state reimbursement limits.
Sequencing the payoffs at settlement
Resolve the claims in the order the settlement dollars would actually flow. Start with the payer whose claim is legally strongest and least reducible — usually a self-funded ERISA plan with tight recovery language — because that number is closest to fixed and tells you what is left for everyone else. Then work the state-regulated plans, where § 3040 reductions and made-whole arguments give you room. Handle the public programs on their own tracks: Medi-Cal reductions run through Ahlborn and Welf. & Inst. Code § 14124.72, and if a managed-care plan holds the Medi-Cal claim the analysis shifts, as covered in our piece on Medicaid MCO liens and the anti-lien limits. Medicare's conditional payments should be knocked down before the final demand issues rather than after, a point we develop in cutting down a Medicare conditional payment before final demand.
The made-whole argument is strongest exactly in the policy-limits case that opened this article. When $100,000 in available coverage cannot begin to compensate a permanent injury, no payer was repaid ahead of a fully compensated plaintiff, because the plaintiff was never close to whole. State-regulated plans yield to that reality by statute and doctrine. The self-funded plan may not have to — which is why you priced its claim first.
Closing observation
Multiple coverages look like a bigger repayment problem and usually are a smaller one. Coordination rules stop the bills from being paid twice, so the total paid across all plans rarely approaches the charged amount, and California's reimbursement caps shave the state-regulated share again on the way out. The one payer that can ignore all of that is the self-funded ERISA plan with airtight recovery language. Identify that plan on intake, price its claim first, and the rest of the file sorts itself in order.
