What to do, step by step
Read the decision and the rules
Find the exact reason for the decision and the appeal instructions in the letter you received, along with any policy, handbook or plan rules that apply. Note the appeal deadline right away.
Gather your evidence
Collect documents that answer the stated reason: records, emails, letters from doctors or teachers, policy language, timelines. Evidence is what changes decisions.
Fill in your letter
Answer the questions above. Stay calm and factual, address the reason for the decision directly, and ask for a specific outcome.
Send it on time and keep proof
Submit the appeal the way the instructions say, before the deadline. Use a trackable method or get a confirmation, and keep a copy of everything you send.
Follow up and prepare for next steps
If you haven't heard back within the expected time, follow up in writing. Ask whether there's a hearing or a further level of appeal if the answer is no.
What if your appeal is denied or ignored?
Many decisions have more than one level of review. A denied first appeal can often be taken to a higher authority, such as a dean or provost, a higher level of the agency, an independent reviewer or a formal hearing. Your decision letter or the organization's policies usually explain the next step and its deadline.
If you don't get a response, follow up in writing, refer to the date you sent your appeal and ask when you can expect a decision. Keep a log of every contact. For insurance, government benefits or employment matters, a state agency or ombudsman may also be able to help.
For high-stakes decisions, such as losing a job, benefits, insurance coverage or your place at a school, consider getting help from a legal aid organization, a union representative, a student advocate or a patient advocate. Many offer free or low-cost assistance.

Re: Appeal of the denial of coverage for my knee MRI performed on August 18, 2026 — Claim number GS-2026-118406
Dear Appeals Committee, Golden State Health Plan,
I am writing to formally appeal the denial of coverage for my knee MRI performed on August 18, 2026, which was communicated to me on September 12, 2026. I respectfully ask that you review this decision for the reasons below.
The denial letter states that the MRI was not medically necessary because conservative treatment had not been tried first. That is not correct. As my enclosed records show, I completed six weeks of physical therapy and a course of anti-inflammatory medication before my orthopedic doctor ordered the MRI. My symptoms did not improve, and my doctor needed the MRI to determine whether I have a torn meniscus. Your plan's coverage policy for knee imaging allows an MRI when symptoms persist after at least four weeks of conservative treatment, which is what happened in my case.
I have enclosed the following documents to support my appeal: a letter of medical necessity from Dr. Karen Liu, my physical therapy records from June and July 2026, and a copy of the denial letter.
For these reasons, I respectfully ask that you reverse the denial and approve coverage for the MRI under my plan.
I would welcome the opportunity to discuss this appeal or to provide any additional information you need. Please send your decision in writing to the address above. Thank you for your time and careful consideration.
Sincerely,
Alex Morgan
Frequently asked questions
How do you start an appeal letter?
Open by stating exactly what you're appealing and when you were notified, with any reference number, then say you're asking for the decision to be reviewed. Putting this in the first sentence makes sure your letter is routed and logged as a formal appeal.
How long should an appeal letter be?
Usually one to two pages. Cover the decision, the reasons it should change and the outcome you want. Put detailed evidence in attachments rather than the letter itself, and refer to each one so the reviewer can find it.
What tone should an appeal letter have?
Respectful, calm and factual. Acknowledge responsibility where it's yours, correct errors politely and avoid accusations or emotional language. Reviewers are more likely to reconsider when the letter reads as reasonable and well documented.
Is there a deadline to appeal?
Almost always, and it can be short. Look for it in the decision letter, policy, handbook or plan documents. If you're close to the deadline, send your appeal on time even if you're still gathering documents, and say you'll send more.
Should I send my appeal by email or mail?
Follow the instructions in the decision letter. If you can choose, use a method that creates a record, such as an online portal, email with confirmation or certified mail, and keep copies of what you sent and when.
