RE: Policy Number NUMBER appeal for claim denied. Claim number NUMBER

Dear Name of Claims Director,

I am writing to appeal the denial of authorization for [treatment/service] on [date of denial]. 

As you may know, [treatment/service] is an essential part of my [medical condition] treatment plan and has been recommended by my treating physician, [Name of Doctor].

I have included a copy of my medical records and test results, which demonstrate the need for this treatment. 

Without [treatment/service], my condition is likely to deteriorate, leading to more serious and costly medical problems in the future.

I am requesting that you reconsider your decision and authorize the [treatment/service] as soon as possible. 

I understand that my insurance plan may not cover the entire cost of this treatment, and I am willing to pay any applicable out-of-pocket expenses.

Thank you for considering my appeal. If you have any questions or require any additional information, please do not hesitate to contact me at [phone number] or [email address].
