What documents do I need for an appeal?
Build your file once — reference it every time.
A strong appeal is usually a well-documented one. This checklist covers everything worth gathering, organized by where it comes from.

Not every appeal needs every item — use what's relevant to your specific situation.
Insurance documents
Medical documents
Provider & billing documents
Your own records
How to request an itemized bill
You have the right to ask for one
An itemized bill breaks down every charge by service and code — far more detail than a standard statement, and often essential for a strong appeal.
Your document tracker
- Denial letter — requested / received / not needed
- EOB — requested / received / not needed
- Medical records — requested / received / not needed
- Letter of medical necessity — requested / received / not needed
- Itemized bill — requested / received / not needed
- Plan document / SBC — requested / received / not needed
Tips for getting records quickly
Ask in writing
A written request (email or portal message) creates a timestamp and record of your request.
Know your rights
You generally have a legal right to your own medical records — most providers have a standard turnaround time.
Follow up if it's slow
If records don't arrive within the provider's stated timeframe, a polite follow-up call often speeds things up.
In Canada? What you gather depends on which plan you're appealing to.
Jump to the Canadian guide ↓Similar categories, different sources
The same four categories generally apply — insurance, medical, provider, and personal records — but where they come from differs.
Private or workplace plan
Your denial letter, EOB-style statement, and plan booklet come from your insurer or plan administrator — much like the U.S. documents above.
Provincial program
Correspondence and forms come from your provincial health ministry — medical records still come from your treating provider either way.

Common questions about appeal documents
Do I need every document on this list?
No — gather what's relevant to your specific denial. A coding error, for example, may need far less than a medical necessity dispute.
Is there a cost to request my medical records?
Sometimes a reasonable copying or processing fee applies, though rules vary by provider and location — ask when you make the request.
What if my provider won't write a letter of medical necessity?
Ask directly about their concerns — sometimes a different provider involved in your care is better positioned to write it.
Should I send originals or copies?
Generally send copies and keep your originals — insurers don't need to keep your only copy of anything.
