This guide will help you understand why Labcorp bills are denied, how to fix the issue, and what steps to take next.
Why Was My Labcorp Insurance Claim Denied?
Here are the most common reasons:
- Out-of-network provider
- Missing pre-authorization
- Wrong billing code or patient info
- Policy doesn’t cover the test performed
- Incorrect insurance details submitted
Tip: Start by reviewing your Explanation of Benefits (EOB) from your insurer—it shows why the claim was rejected.
How to Fix a Denied Labcorp Claim
- Call Your Insurance Provider
Confirm the reason for denial and ask what needs to be corrected. - Review the Bill with Labcorp
Contact Labcorp Billing: (800) 845-6167. Ask them to verify submitted info like policy number, test code, or diagnosis. - File an Appeal
If the test should have been covered, your insurer will often allow you to submit an appeal with support from your doctor. - Get a New Invoice from Labcorp
Once the issue is resolved, request a corrected invoice or updated balance.
Will I Have to Pay Out-of-Pocket?
You might have to pay the bill yourself if:
- Labcorp was out-of-network for your plan
- Your plan didn’t cover the test
- The issue isn’t resolved with appeal
However, Labcorp may offer self-pay rates or payment plans to help reduce the burden.
