Health insurance denial & claim adjustment codes

What health insurance denial code 205 means on your EOB

A fee tied to a discount card. Worth comparing against what the drug costs with no insurance at all — sometimes cash wins.

What usually causes it

• A discount card was used rather than the benefit.
• A processing fee applied.
• The benefit may have been cheaper.

The documents that decide it

• Your receipt showing the card used.
• The benefit price for the same fill.
• The cash price.

What to do next

Ask the pharmacy to run all three prices: benefit, discount card, and cash. They are often materially different.

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.
