Health insurance denial & claim adjustment codes

What health insurance denial code 209 means on your EOB

Explicitly not billable to you. If you received a bill for this, that is the finding.

What usually causes it

• The provider's contract prohibits collecting from you.
• A subsequent payer may be billed instead.
• The amount is a contractual adjustment.

The documents that decide it

• Your EOB showing this code.
• Any bill you received.
• The provider's network status.

What to do next

The code says the provider cannot collect this from you. Send the EOB to their billing office.

This page explains what a code means. It is information, not advice — it does not tell you whether your specific claim should have been paid, and it is not legal, medical, or insurance advice. Your plan documents and your denial notice govern your situation.
