🪜 Step-by-step
- Read the denial reason carefully - coding error versus coverage exclusion lead to different fixes.
- Ask your provider to correct or resubmit claims where billing codes were wrong.
- File an internal appeal within deadlines (usually 180 days), attaching medical necessity evidence.
- Request a full copy of your file and plan rules the insurer used against you.
- If internal appeal fails and involves over $1,000 or clinical judgment, request external independent review through your state.
