Two very different animals
Personal injury settlements attract claims from several directions, but they fall into a few families that behave very differently. Statutory liens are created by a specific law, such as a state hospital lien act or the federal Medicare Secondary Payer statute. Contractual reimbursement claims come from a health plan document, and when that plan is a self funded employer plan governed by ERISA, the federal statute changes the rules dramatically. Treating all of these the same way is how firms overpay.
Statutory liens: the rules are written down
A statutory lien lives and dies by its statute. A hospital lien act, for example, typically limits the lien to reasonable and necessary charges, imposes notice requirements, and often caps the lien as a share of the recovery or subordinates it to the attorney fee. Because the limits are in the text, the path to reducing the lien is to hold the holder to the statute: challenge unreasonable charges, enforce the cap, and insist on proper notice.
Government liens are their own category of statutory claim. Medicare conditional payments and Medicaid recovery each follow detailed federal and state frameworks with defined reduction and appeal procedures. They are powerful, but they are also bounded by rules you can use. Our Medicare and Medicaid and Medi-Cal pages walk through each.
ERISA plans: why they hit harder
A self funded ERISA plan is different because the federal statute can preempt state law. That matters enormously. Many of the defenses that limit other liens, such as state made whole rules and anti subrogation statutes, can be overridden by a self funded ERISA plan with the right language. The Supreme Court decisions in Sereboff and Montanile shaped how these equitable reimbursement claims work, including the requirement that the plan pursue an identifiable fund.
The result is that a self funded ERISA plan can, in the right circumstances, claim full reimbursement off the top. But two words carry all the weight: self funded and language. An insured plan does not get ERISA preemption in the same way, and even a self funded plan is only as strong as its actual document. That is why every ERISA claim starts with reading the plan, not the demand letter. See our ERISA and subrogation resolution page for how we test them.
The practical difference in one table of thinking
- Hospital lien. Governed by state statute. Reduce it by auditing charges, enforcing reasonableness, and applying statutory caps and notice rules.
- Medicare. Governed by the Medicare Secondary Payer statute. Reduce it by disputing unrelated charges and applying the procurement cost reduction, waiver, and compromise.
- Medicaid and Medi-Cal. Governed by state recovery law within federal Medicaid. Reduce it with the Ahlborn allocation and common fund principles.
- Insured health plan. Often subject to state made whole and anti subrogation rules, which create meaningful room to reduce.
- Self funded ERISA plan. Can preempt those state rules, so leverage comes from the plan document itself, whether it is truly self funded, and the timing and tracing rules from Montanile.
Why the distinction is worth money
If you treat an insured plan like an untouchable ERISA plan, you leave money on the table. If you treat a genuine self funded ERISA plan like an ordinary contract claim, you can mishandle a real obligation and expose the file. The reduction strategy has to match the lien type. Getting that classification right at the start is the highest leverage move in the whole process.
