Asks your plan to explain how it set the allowed amount for out-of-network care, to reprocess the claim if the method was wrong, and to pay the difference.

This one is for a specific kind of coverage
It is written for the coverage tagged above. If you have a different kind (for example Medicare or Medicaid instead of a job-based or individual plan), it may cite the wrong rules. Check what kind of coverage you have and use the letter written for it.
When to use this, and what it is not
When to use this. Use this when your plan paid an out-of-network claim but allowed far less than the provider charged and you cannot tell how it chose that figure. Have your Explanation of Benefits and the provider's bill beside you.
This is a template, not legal advice. Read it, change anything that is not true for you, and send it only when you are satisfied. Your notice and your plan document control.

Re: Appeal: out-of-network allowed amount too low Plan: [Name of the health plan] Member ID: [Member ID] Claim or reference number: [Claim or reference number]
To the reviewer:
I am appealing how [Name of the health plan] processed claim [Claim or reference number] for [The care or drug that was denied] from [Doctor, hospital or pharmacy] on [Date of the care] (member ID [Member ID]). The provider charged [Amount the provider charged]. The plan allowed [Amount the plan allowed] and paid [Amount the plan paid]. I ask you to reprocess the claim using a correct allowed amount, pay the additional amount that results, and send me a new Explanation of Benefits.
The explanation I received was: [What the Explanation of Benefits says about how the amount was set] I believe the allowed amount is too low because: [Why you think the allowed amount is too low]
Please explain in writing how the allowed amount was calculated. I ask for the method used (for example a fee schedule, a percentage of a Medicare rate, or a usual and customary rate), the fee schedule or data source and its date, and the plan provision that sets the method. My plan documents say: [What your plan documents say about paying out-of-network care] If the plan used a method different from the one its documents describe, I ask you to reprocess the claim using the documented method.
Under the federal claims and appeals rules, including Title 29 of the Code of Federal Regulations (CFR), sections 2560.503-1 and 2590.715-2719 (for individual coverage, 45 CFR 147.136), I am entitled to a full and fair review. I ask that someone who was not involved in the first decision, and who is not that person's subordinate, decide this appeal and give no deference to the first decision. Please consider every document and comment I send.
Please send me your decision in writing within the time the rules allow. If the plan keeps the same amount, I will pursue every further review available to me, including a complaint to the agency that regulates my plan.
Enclosures: 1. Copy of the Explanation of Benefits 2. The provider's itemized bill 3. The page of my plan document about out-of-network payment 4. Any quote or comparison I obtained
Sincerely, [Your name]
Before you send it
Send it to the appeals address printed on your denial notice, by a method that proves delivery, such as certified mail with a return receipt or the plan's online portal with a saved confirmation page. Keep a complete copy of the letter and everything you enclose, and write down the date and the method you used.
What to enclose
- Copy of the Explanation of Benefits
- The provider's itemized bill
- The page of my plan document about out-of-network payment
- Any quote or comparison I obtained
What happens next
- Your plan must decide within 60 days after it receives your appeal, because the care has already happened. If your plan has two appeal levels, each level gets 30 days. Check the date on your notice, which controls.
- Ask the provider's billing office in writing to hold the bill while you appeal; they are not required to. If the plan treats this claim as covered by the No Surprises Act, you owe only in-network cost sharing. Otherwise the provider may bill you the difference, and an unpaid bill can go to collections, so ask the provider or a legal aid office what happens if you do not pay before you withhold any payment.
- External review covers decisions that involve medical judgment, so a pure payment-amount dispute may not qualify. If the claim falls under the No Surprises Act, a denial or cost sharing that turns on those protections can go to external review. Check your notice for what it offers.
- If the plan keeps the amount, complain to the agency that oversees your plan. Complaints about an insurance company go to your state insurance department; complaints about a private employer plan go to the United States Department of Labor.
- If you are writing for someone else, tick "I am writing for someone else". The plan may require its own authorization form. See the letter "Name someone to act for you".

- Denial reason
Allowed amount too low
Your plan paid an out-of-network provider only part of the bill and says the rest is above its allowed amount. Check how the plan set that amount, whether surprise-billing protections apply, and what typical prices are in your area.
