Letter of Protection 2025: Treating on a Lien Explained

## What a Letter of Protection Does

A letter of protection, often abbreviated LOP, is a written agreement in which your attorney promises a medical provider that the provider will be paid from your eventual settlement. In exchange, the provider treats you now, even though you cannot pay at the time and may have no health insurance. The LOP effectively turns your future settlement into the funding source for your medical care.

For injured people without insurance, an LOP can be a lifeline. It allows access to surgeons, specialists, and diagnostic testing that would otherwise be out of reach. But an LOP is also a lien, and it carries real consequences for your final net recovery that you should understand before signing.

When a Letter of Protection Makes Sense

An LOP is most useful in specific situations:

1. **You have no health insurance** and need care that you cannot pay for out of pocket.
2. **Your health insurance refuses to cover** accident-related treatment until liability is determined.
3. **You need a specialist** who does not accept your insurance but will treat under a lien.
4. **You need documentation** of your injuries from a provider willing to support your claim.

In each of these cases, the LOP bridges the gap between needing care and having the money to pay for it.

The Cost Side of an LOP

The convenience of an LOP comes at a price. Providers who treat on a lien often bill at full retail rates rather than the discounted rates a health insurer would negotiate. Because there is no insurer pushing the price down, the balance owed at settlement can be far higher than it would have been through insurance.

This matters because every dollar of LOP balance reduces your net recovery. A surgery that an insurer might have settled for 8,000 dollars could generate a 25,000 dollar LOP balance. That difference comes directly out of your pocket at the end of the case.

Negotiating the LOP Balance at Settlement

The good news is that LOP balances are negotiable, often substantially. Providers who treat on liens understand that settlements are uncertain and that getting paid something is better than nothing. Effective negotiation strategies include:

• **Comparing the lien to insurance rates.** Show what the same care would cost through an insurer and argue the lien should approach that figure.
• **Applying the common fund doctrine.** Argue the provider should share in the attorney fees and costs that produced the [settlement](/settlement).
• **Showing the global picture.** When multiple liens compete for limited funds, providers accept reductions to ensure prompt payment.
• **Leveraging case risk.** If liability was disputed, the provider knows the recovery could have been zero.

A skilled [attorney](/lawyer) builds these arguments into a reduction request that can cut an LOP balance significantly.

How an LOP Affects the Disbursement

When your case settles, the LOP provider must be paid before you receive your share. The disbursement sequence typically runs:

1. Attorney fees and case costs.
2. Statutory and contractual liens with priority.
3. LOP balances, after negotiation.
4. The remaining net to you.

Because LOP balances can be large, addressing them early and negotiating them down is critical to a healthy net recovery.

Risks to Keep in Mind

An LOP carries risks beyond the higher cost:

• **Overtreatment concerns.** Some lien-based providers are criticized for excessive treatment. Defense attorneys may attack inflated lien-based bills, which can lower your overall case value.
• **Credibility issues.** A jury may view lien-based treatment with skepticism if it appears driven by litigation rather than genuine medical need.
• **No guarantee of full payment.** If your case value is low, you remain responsible for the balance the settlement cannot cover.

Choosing reputable providers and reasonable treatment protects both your health and your case.

Letter of Protection Versus Using Health Insurance

When you have health insurance, using it is usually cheaper than an LOP because of negotiated rates, even though your insurer will assert a subrogation claim. The insurer reimbursement is typically based on the discounted amount it actually paid, which is lower than full retail LOP billing. We compare these paths in detail in our article on health insurance versus liens, but the general rule is to use insurance when available and reserve LOPs for situations where insurance is not an option.

Protecting Yourself Before You Sign

Before agreeing to treat under a letter of protection:

1. Confirm the provider is reputable and the treatment is medically necessary.
2. Ask your [lawyer](/lawyer) to explain how the LOP will affect your net recovery.
3. Understand that you remain responsible if the settlement falls short.
4. Keep copies of the LOP and all itemized bills for later negotiation.
5. Confirm relevant deadlines under the applicable [statute](/statute).

The Bottom Line

A letter of protection opens the door to necessary care when you cannot pay upfront, but it shifts cost to the back end of your case in the form of a negotiable lien. Use LOPs wisely, choose providers carefully, and negotiate the balances hard at settlement to protect your net recovery.
