Colorado Hospital Liens vs. Health Plan Subrogation

A young man visiting Colorado from the East Coast went to a Denver-metro emergency room twice in a matter of days. The bills came to roughly $39,000. He had health insurance the entire time. Weeks later he learned that the hospital had filed a lien against his injury claim — not a bill, a lien — for the full $39,000, without ever sending a claim to his health plan.

He was stunned. He shouldn't have been the only one. Under Colorado law, that lien should not have existed.

This article is about the two very different claims that come out of a Colorado personal injury settlement — a hospital lien and a health plan's reimbursement claim — and why treating them as the same thing costs injured people real money. They are governed by different statutes, they carry different protections, and the amount each one collects can differ by a factor of ten on identical facts. Nothing here is legal advice, and Colorado's rules do not travel: every state writes its own lien and subrogation law.

Two claims on the same settlement, two different rulebooks

Colorado's subrogation statute, C.R.S. § 10-1-135, is genuinely protective. It says a health plan may seek reimbursement out of your settlement only if you have first been fully compensated for all of your damages, and that any policy language saying otherwise is void as against public policy. It requires the plan to absorb a proportionate share of your attorney fees and costs. It bars the plan from being named as a co-payee on your settlement check.

Then subsection (10)(b) says the statute does not modify hospital lien rights under C.R.S. § 38-27-101.

That single clause is the most consequential sentence in this area of Colorado law and almost nobody explains it to clients. A hospital lien sits outside the protective statute. No made-whole requirement. No sharing in your attorney fees. It attaches to the net amount payable to you out of any recovery, at full billed charges, and it stays there.

Which means the single most valuable thing that can happen to an injured person's settlement is often not a negotiation at all. It is moving a claim from one statute to the other.

A $39,000 lien that should never have existed

Section 38-27-101(1) is a precondition, not a suggestion. Before a lien is created, a licensed hospital treating someone injured by another person's negligence must submit its reasonable and necessary charges to the property and casualty insurer and to the primary medical payer of benefits identified by or for the patient — billed in the same manner the hospital bills patients who were not injured by someone else. Subsection (2) permits a lien only where no payers of benefits were identified due to lack of insurance.

Subsection (9) defines "payer of benefits" expansively: an insurer, an HMO, a health benefit plan, a PPO, an employee benefit plan, or any other insurance policy or plan. There is no in-network requirement and no exception for out-of-state coverage. A visitor's East Coast plan is a payer of benefits.

And the legislature attached a consequence. Subsection (7) lets a person subjected to a lien in violation of the section sue to recover two times the amount of the lien.

This structure arrived in 2015 through Senate Bill 15-265, and its sponsorship is worth noticing. As the Colorado Court of Appeals recorded in Garcia v. Centura Health Corp., 2020 COA 38, the bill was sponsored by Republican Senator Bill L. Cadman and Democratic Representative Dickey Lee Hullinghorst. The bill summary described its purpose without much decoration: require a hospital to submit its charges to the patient's payer of benefits before a lien for hospital care is created. Two legislators, two parties, two chambers, one patient-side fix. A great deal of legislation gets built out of somebody's specific bad experience, and the impulse to fix it is not the property of either party.

Why you may never learn the lien was filed

Hospital liens are filed with the Colorado Secretary of State, in the same system that holds UCC filings. Section 38-27-102 requires the hospital to file written notice there before any judgment or settlement, and — separately — to mail a copy by certified mail, return receipt requested, within ten days, to the injured person at the last address they gave the hospital, to their attorney if known, to the alleged at-fault party if known, and to that person's insurance carrier if known.

In twelve years of handling these claims, I have very rarely received an actual lien filing in the mail. That is worth saying plainly, because it reframes the risk. The common failure is not a hospital that refuses to withdraw an improper lien. It is a lien nobody ever finds — quietly encumbering a settlement, and in the meantime sitting on a credit report as an unpaid balance for care that insurance would have covered.

There is a wrinkle here that cuts in the patient's favor. In Wainscott v. Centura Health Corp., 351 P.3d 513 (Colo. App. 2014), the court held that substantial rather than strict compliance satisfies the § 38-27-102 filing and notice formalities — minor technical defects do not invalidate an otherwise valid lien. But the court anchored that holding to a specific condition: a lienholder substantially complies when it gives timely actual notice to those against whom it seeks to enforce the lien. Read the other direction, the hospital's own safe harbor depends on the notice having actually arrived.

Note also what Wainscott did not address. It was decided in 2014, before the amendments, and it concerned the § 38-27-102 formalities — not the § 38-27-101(1) requirement to bill identified insurance before creating a lien at all. That requirement is a condition on the lien's existence, and the legislature paired it with an express remedy. Wainscott itself reasoned that when a statute plainly declares the consequence of noncompliance, that signals an intent to require strict compliance.

What the letter actually does

The fix on that $39,000 file was not elaborate. A letter to the hospital at the address on the lien filing, stating that the patient had health insurance. Then a phone call to the billing department providing the policy information. The lien was withdrawn, the client's record was cleared, and the charges went to his health plan.

The reason such a short letter works is subsection (3). If a hospital is notified of a payer of benefits after it creates a lien, it must make good-faith attempts to submit the charges to that payer, billed the same way it bills non-tort patients. Identifying the insurance is the operative act. It converts the hospital's position from "no payers were identified" — the only condition under which a lien may exist — into a live statutory duty to bill.

We do invoke the double-damages exposure in that letter. We are generally not trying to collect on it. There is legitimate plaintiff-side practice treating these as freestanding wrongful-lien claims for statutory damages, and Colorado's appellate courts have taken those claims seriously — in Garcia v. Centura Health Corp., 2025 CO 15, the Colorado Supreme Court twice relieved a wrongful-lien claimant of broad discovery demands, reminding the district court that statutory damages in such cases are established by law. That is a real avenue and lawyers who pursue it are doing something worthwhile.

Our reasoning for the other road is narrower. A client came to us about an injury. The lien is an obstacle to resolving that injury claim, and turning the obstacle into a second lawsuit adds years and a new defendant without delivering what the client came for. A statute you never sue on still has teeth: the exposure is real, the billing department knows it is real, and that is usually enough.

The made-whole gate and the fee reduction nobody mentions

On the health-plan side, § 10-1-135 contains two mechanics most injured people have never heard of.

The presumptions run on coverage limits

Under subsection (3)(d)(I), if you recover less than the total coverage available, you are presumed to have been fully compensated — so reimbursement survives. If you recover an amount equal to the total coverage available across all liability and UM/UIM policies, you are presumed not to have been fully compensated. And under subsection (4)(b), if the recovery does not fully compensate you, the plan has no right to repayment at all. Not reduced. None.

To invoke that, subsection (4)(a)(II) requires notice to the plan within 60 days of receiving each recovery, including the amount and source of the recovery and the applicable coverage limits. A confidentiality provision in the settlement agreement is unenforceable as to that required disclosure. We send those notices as a matter of course on policy-limits settlements, because that is precisely where the presumption is worth invoking. In twelve years I have never had a plan demand the arbitration the statute permits. What happens more often is that the deadline passes without a response.

The plan pays a share of your legal fees

Subsection (3)(c) reduces whatever the plan can recover by its proportionate share of the attorney fees and expenses incurred in obtaining the recovery, based on the ratio of those fees and expenses to the recovery. This happens by operation of law, not by negotiation. If fees and costs together come to 35% of the recovery — an illustration, not our rate — then a plan asserting $8,000 collects roughly $5,200. Run the ratio in your own fee agreement against the plan's number and you will see what the statute is worth to you.

Where the money actually lands: a $50,000 illustration

Consider a composite of a common file — an illustration of how the math works, not a case result. A $50,000 settlement. A chiropractor holding roughly $3,000 on an informal agreement with the patient. A health plan that paid about $8,000 toward an ambulance, an emergency room visit, imaging, and an orthopedist. Costs on a pre-suit soft-tissue file like this run modestly: $10 for the traffic crash report and roughly $450 to $550 for medical records and imaging, or about $2,000 more if bills or records need expert review.

The $8,000 is the same $8,000 in all three columns below. What changes is only which legal regime governs it.

The spread between the best and worst column is about $8,000 on a $50,000 case — roughly sixteen percent of the gross, decided by which statute applies rather than by anything about the injury, the treatment, or the negotiation. If you want the fuller picture of how a settlement becomes a net check, we walk through it in how much of a personal injury settlement you actually keep.

Where these protections stop: self-funded plans, Medicare, Medicaid

Section 10-1-135 is a state insurance statute, and that limits its reach in ways most articles on this subject skip.

The dividing line is not geography. It is whether the plan is fully insured or self-funded. In FMC Corp. v. Holliday, 498 U.S. 52 (1990), the United States Supreme Court read ERISA's deemer clause to exempt self-funded employee benefit plans from state laws regulating insurance, while holding that insured plans remain subject to indirect state regulation because the insurance company issuing the policy is still an insurer. So a fully insured plan issued in Colorado is bound by § 10-1-135 through its insurer. A self-funded plan — what most very large employers run — is not, regardless of where the employee lives or works.

That is the hardest version of this problem I encounter. I have spent a week tracking down the vice president of benefits at a Fortune 500 self-funded plan only to be told the plan could not reduce and would not, in part because recovery had been contracted out to a vendor compensated on a percentage of what it collects. I have sat at mediation while a former judge got the employer's in-house counsel on the phone, and the answer was still no. The client had given that company forty years. Worth understanding why: with many self-funded plans the person you finally reach has no authority to reduce, and the entity with authority has no financial incentive to. That is a structure, not a personality.

Two further carve-outs. Subsection (2)(c)(II) writes a program of medical assistance under the Colorado Medical Assistance Act and the children's basic health plan out of the definition of "payer of benefits" entirely. Medicare operates under its own federal framework for reimbursement purposes. None of those are governed by the subrogation mechanics described above.

Medicare deserves a separate note on the hospital lien side, because it has been genuinely contested. Divisions of the Colorado Court of Appeals split on whether Medicare counts as a patient's "primary medical payer of benefits" that a hospital must bill before creating a lien, and the question went up to the Colorado Supreme Court. If you are a Medicare beneficiary facing a hospital lien, that is a point to have current counsel check rather than something to settle from an article.

The handshake bill the statute ignores

Which brings us to the $3,000 chiropractor — the item with the least legal machinery attached and, for that reason, often the least reducible.

An informal agreement between a provider and a patient is not a hospital lien; § 38-27-101 reaches licensed hospitals. And a treating provider is not a payer of benefits, so § 10-1-135's made-whole gate and fee-sharing formula do not touch it either. It is a contract. Where we have notice of one, we advise the client on their options, and in practice those balances are usually paid in full or negotiated down slightly.

That is the honest shape of Colorado law here, and it is close to the opposite of what most people would guess. The legislature built careful protections around the institutional claims — the hospital that skips your insurance, the health plan that wants repayment before you are made whole — and left the small handshake balance almost entirely to the relationship between a patient and their provider. Knowing which of your bills is which, before the settlement check is cut, is most of the work. Consistency of treatment matters here too, for reasons we cover in what a gap in treatment costs you in Colorado.
