An underpayment is when a payer pays less than the contracted allowed amount for a service. Because the claim was paid — just not fully — underpayments often slip by unnoticed unless payments are compared against the expected fee schedule.
They can result from loading errors on the payer side, incorrect adjustments, or bundling that was not warranted.
Why it matters for billing
Underpayments are quiet revenue leakage: the claim shows as paid, so no one works it. Comparing every payment to the contracted allowed amount surfaces the gap, and those dollars are often fully recoverable through a straightforward appeal.
