Health insurance denial & claim adjustment codes

What health insurance denial code 19 means on your EOB

The plan says workers' compensation should pay. If your injury was not work-related, this is a factual dispute you can win with documentation.

What usually causes it

• The injury was recorded as work-related.
• A workers' comp claim exists for a different injury.
• The plan is defaulting to comp without evidence.

The documents that decide it

• How and where the injury occurred.
• Any workers' comp filing or denial.
• Your provider's intake record.

What to do next

If workers' comp already denied it, send that denial to your health plan — it usually resolves the dispute immediately.

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.
