Part of: Build your case

Step 2 of 3 in the journey

Appeals are won on paper.
Gather it before you write.

The people who review an appeal read a file. Your job is to make sure that file contains what they need to say yes: what the plan relied on, what your records show, what your doctor says, and what the plan's own documents promise.

Not sure what to collect? Start with the claim file.
