A letter of protection is usually an agreement connected to an injury claim where a provider may wait for payment until the case resolves, but the details vary.
It is a billing arrangement, not a guarantee that treatment is free or that a claim will succeed.
The basic idea is delayed payment
In some accident cases, a provider may treat now and agree to seek payment later from a settlement or claim process. The document is often called a letter of protection, or LOP. It can involve the patient, provider, and attorney, depending on the setup. The important point is that delayed billing does not erase financial responsibility. Ask who is responsible if the claim does not resolve as expected.
Read the financial responsibility language
Before signing, ask what services are covered, what rates are used, whether interest or fees apply, whether records will be sent to an attorney, and what happens if you stop treatment. A clinic should not rush this conversation. If you are still comparing billing paths, read getting care before a claim is settled. An LOP is one possible path, not a universal solution.

A chiropractor can explain its billing policy, but it should not act as your lawyer. USA.gov points consumers toward legal-aid resources, and private attorney advice may be needed for claim-specific questions. Ask your attorney, if you have one, how the LOP affects settlement distribution, medical bills, and your obligations. Keep a copy of the signed document with your records.
Use the LOP to clarify, not to over-treat
A delayed-payment arrangement should not replace clinical judgment. Ask what the first evaluation found, why visits are recommended, when progress will be reassessed, and what symptoms require referral. If the care plan changes, ask whether the LOP still covers the new services. Write down the billing route, who receives records, and who answers balance questions. Add one practical detail that proves the issue is current: the date you requested a record, the claim number you were given, the first work task you missed, the symptom that changed driving, or the exact document still missing. When you call, use a simple script: I was in a crash on this date, this symptom is affecting this task, this document is missing, and I need to know whether the visit can proceed. Then ask who needs the next document and by what deadline. Write down the person or department responsible for follow-up after the call. Save screenshots or emails that confirm the request, because portal messages and claim notes can disappear from memory quickly. That kind of detail is more useful than a long emotional summary. It helps the next office decide what belongs in the medical record, what belongs in billing, and what should be routed to insurance or legal help.
Your next clear action
Make a one-page file before the next call: crash date, your role in the crash, current symptoms, prior care, claim information, missing documents, and the one decision you need answered today. If severe, neurological, chest, breathing, abdominal, or rapidly worsening symptoms are present, choose urgent medical care first. Otherwise, call the office or insurer and ask one direct question at a time. Write down the representative's name, date, answer, and next deadline. Keep that note with your medical and billing records so every future conversation starts from the same facts. Write down what to bring, what to watch, and which symptom should change the plan.
When to seek urgent care
Do not wait on severe warning signs
Seek urgent medical care if you have severe or worsening pain, weakness, numbness, repeated vomiting, confusion, slurred speech, loss of consciousness, seizure, chest pain, trouble breathing, or other serious symptoms after a crash.
Practical checklist
Details worth gathering before you call
- Your auto insurance information and any claim number you have.
- The accident date, location, and basic crash details.
- Symptoms that showed up right away or appeared later.
- Any paperwork from urgent care, the ER, or another provider.
Questions people ask
Direct answers
Does a letter of protection mean I owe nothing?
No. It often means payment may be delayed or tied to a claim process. You need to understand what happens if the claim is denied, delayed, or settles for less than expected.
Can a chiropractor explain an LOP?
The office can explain its billing policy and what it asks patients to sign. Legal consequences should be discussed with an attorney or qualified legal resource.
Should I sign an LOP before the first exam?
Do not sign anything you do not understand. Ask what services it covers, what rates apply, who gets records, and what your responsibility could be.
