Your health insurance denied a claim as billing or coding error. What it means, your deadline, and how to appeal.
Check my letter freeWhat it means
The claim has missing information or a coding mistake.
What to do
Call the provider's billing office and ask them to correct the claim and send it again.
You may not need a formal appeal: a corrected claim is often enough.
Your deadline
Most plans give you 180 days from the denial notice to file an internal appeal. Original Medicare gives 120 days from the Medicare Summary Notice, and Medicare Advantage plans 65 days from their decision. Check the date printed on your letter.
If the plan says no again
After a final denial from a marketplace or employer plan, you can ask for an external review by an independent reviewer within 4 months. If the reviewer decides for you, the plan must pay.
Ask for your claim file
You have the right to receive, free of charge, copies of the documents and the criteria used to decide your claim.
