How to Handle Insurance Claim Underpayment

Not all insurance disputes involve outright denials. Sometimes the insurer approves your claim but pays less than expected. This guide helps you identify and fight claim underpayments.

Signs of Underpayment

  • Your out-of-pocket cost is higher than expected
  • The insurer applied a different (lower) billing code than the provider submitted
  • The allowed amount seems unreasonably low
  • Multiple services were bundled into a single payment
  • Your deductible wasn't credited correctly

Common Causes

Downcoding

The insurer changes the billing code to a less expensive service. For example, coding an office visit as "brief" when your doctor coded it as "extended."

Bundling

The insurer combines multiple separate services into one payment, paying less than if each were paid individually.

Incorrect Allowed Amount

The insurer's contracted rate or usual and customary rate may be applied incorrectly.

Coordination of Benefits Errors

If you have two insurance plans, the primary and secondary may not coordinate correctly.

How to Dispute

  1. Compare the EOB to the original claim submitted by your provider
  2. Verify the billing codes match what your provider submitted
  3. Check that your deductible and out-of-pocket credits are accurate
  4. Call the insurer to request a detailed explanation of the payment
  5. If errors exist, ask the provider to submit a corrected claim
  6. File a formal appeal if the insurer refuses to correct the underpayment
  7. Escalate to your state insurance department if necessary

Frequently Asked Questions

What is downcoding?

Downcoding is when the insurer changes the billing code submitted by your provider to a less expensive code, resulting in lower payment. For example, changing a level 4 office visit (99214) to level 3 (99213). Your provider can appeal this with documentation supporting the original code.

How do I know if my claim was underpaid?

Compare your EOB to the claim your provider submitted. Look for differences in billing codes, check that the allowed amount matches your plan's fee schedule, and verify your deductible and coinsurance were applied correctly.
