Treating on a Lien in Arizona: How Letters of Protection Work

You need treatment, you have no health insurance or a deductible you cannot meet, and the liability claim will not resolve for months. Treatment on a lien exists for exactly this gap, and it comes with terms worth understanding before you sign.

What a letter of protection is

It is a written agreement, usually signed by you and your attorney, promising that the provider will be paid from the settlement rather than billed to you now. The provider treats without payment up front and waits.

In exchange they take real risk. If the case fails or settles for less than the bills, they have a problem, which is why the arrangement is not offered universally and why the rates attached to it are what they are.

The rate question

Lien-based providers frequently bill at rates above what an insured patient’s plan would have paid for the same service. That is defensible given the risk and the delay, and it is also the single thing most likely to reduce what you actually take home.

Ask for the rate schedule before treatment begins. Ask whether the balance is negotiable at settlement, because it usually is, and the answer given at the start tends to be more honest than the answer given at the end.

How defence lawyers use it

Expect an argument that lien treatment was driven by litigation rather than by medical need, that the provider has a financial stake in the outcome, and that the billed amounts exceed reasonable value.

What answers it is an ordinary clinical record. Referrals from a treating physician rather than from a law office. Documented symptoms that justify the treatment. A course of care that ends when you improve rather than when the case does.

Where it sits against everything else

Liens are paid from the gross recovery before you receive anything, alongside health plan reimbursement claims and any statutory liens. On a case limited by the at-fault driver’s policy limits, the bills can approach the whole available amount.

This is why the net figure and the settlement figure are often very different numbers, and why the conversation about liens should happen before the case is close to resolving.

What to check before signing

Whether the balance is negotiable at settlement. What happens if the case fails or recovers nothing. Whether the provider will accept a reduction proportionate to a policy-limits outcome. Whether they report to credit agencies while the case is pending.

Get the answers in writing. A provider who is comfortable with a reduction later is usually comfortable saying so now.

Check your own coverage first

MedPay on your own auto policy pays medical expenses regardless of fault, with no deductible and no network. Plenty of Arizona drivers carry it without knowing, and using it is almost always better than treating on a lien for the same care.

Check the declarations page before you assume a lien is the only route. The two-year limitation period under A.R.S. § 12-542 sets the outer deadline for the claim, but treatment decisions get made in the first weeks and they are much harder to undo afterwards.
