The first 48 hours are for getting organized

You do not need to write the whole appeal today. Read the notice twice, once for the reason and once for the deadline, and start one file for everything.

Mark the deadline

Put the filing deadline on your calendar the same day you read the notice.

Start one folder

Put the denial letter, EOB, doctor letter, records, and every call note in one place.
