What to upload

Your denial letter

The letter that says your plan will not pay. It may be called a "notice of denial" or an "adverse benefit determination".

Or your EOB

The Explanation of Benefits your plan sends after a claim. It shows what was billed, what the plan paid and what you may owe. It is not a bill.

Have both? Add both, and every page. The codes are often on the back or the last page.

A PDF, a photo or a scan. PDF, JPG, PNG or HEIC, up to 20 MB each, 25 MB in all, and 5 files.

  • We read the text on the pages to find the dates, codes, plan type and deadline. We use it only to decode this letter.
  • If you do not save the result, we delete the file and the result 24 hours after you upload it.
  • No ad trackers on this page. We never sell your information or share it for advertising.

Free. No account needed.

By decoding, you agree to the Terms. We explain your letter; we do not give legal or medical advice.

No file? Type the denial reason or code yourselfYou get a shorter result: we can only explain what you type.

Short codes like 50, CO-50 or N115. On an EOB they are often in a "remarks" or "reason" column.

Copy a sentence or two. Leave out your name, member ID and other personal details.

We need it to work out your deadline.

If you do not save the result, we delete what you type 24 hours after you send it.
