Seeing duplicate charges from Labcorp on your statement? You’re not alone. Labcorp double billing is a common issue many patients face—and in most cases, it can be resolved quickly once you know what to do.
Common Reasons for Duplicate Charges
If you notice two charges from Labcorp, here are the most likely causes:
- Test Split Across Different Bills
Sometimes Labcorp splits multiple tests into separate invoices—even if they were done at the same visit. - Insurance Adjustment Delays
If your insurance was billed but didn’t respond quickly, Labcorp may send you a direct bill to avoid delays. - Duplicate Lab Orders
If a provider accidentally ordered the same test twice, you might see separate charges. - Technical Glitch or Billing Error
Like any large system, occasional errors can occur in billing software.
What to Do First
- Compare Both Bills or Charges
Look at the invoice numbers and dates—are they identical or slightly different? - Call Labcorp Billing Support
📱 (800) 845-6167
Ask for clarification and request a review of your account. - Gather Documentation
Have your invoices, insurance explanation of benefits (EOB), and dates of service ready. - Request a Refund or Adjustment
If it’s a confirmed duplicate, Labcorp will typically process a refund or remove the extra charge.
How to Protect Yourself
- Always save a copy of your lab bill and receipt
- Check your insurance provider’s billing status
- Use a credit card so you can dispute payments if needed
- Monitor your account for changes or refund confirmations
