They denied it over paperwork. Not over your care.
Your insurer calls this “Administrative reason”. This page is about what that actually means and what you can do about it.
Nobody has decided anything about your treatment. A form didn't match. That is genuinely good news, because forms can be corrected.
Is this your denial? Look for these words on your letter
“missing information”“incorrect coding”“untimely filing”“duplicate claim”“invalid claim”
Not sure? Work out which denial you have →
The first thing to do. Ask the plan, in writing, exactly what is wrong and which plan provision they are relying on. Vague denials collapse when you make them be specific.
You are not a rare case
11,430,778
claims denied for this reason in the federal data — 18.5% of all categorised denials. This happens constantly, and it is beaten constantly.
Reason to keep going. The cheapest denial to overturn. Often a corrected claim from your provider's billing office fixes it faster than an appeal.
What to do about this denial
- Get the exact wording. Ask for the specific plan provision and clinical criteria relied on. The plan must supply it free of charge on request.
- Answer the reason given, not the diagnosis. An appeal that argues the wrong point fails even when the claim is good.
- Get your treating clinician to write the counter. Their letter carries far more weight than yours alone.
- Internal appeal first, then external review. Internal generally within 180 days of the denial; external generally within 4 months of the final internal denial.
Important for this denial type: external review covers denials involving medical judgement, experimental/investigational determinations, and rescission of coverage. A purely administrative or eligibility denial may not qualify for external review. That is not bad news — administrative denials are usually the easiest to reverse at the internal stage, because you are correcting a record rather than winning an argument. If the plan's reasoning turns out to involve medical judgement, external review is back on the table.
