Payment integrity and disputes

At Humana, we strive to offer our members high-quality healthcare at affordable rates. To achieve this goal, the Humana Provider Payment Integrity (PPI) department reviews claims payments for accuracy and requests refunds if claims are overpaid or paid in error.

Common reasons for overpayment include:

An issue regarding the coordination of member benefits

Duplicate payments

Fraud, waste and abuse detection

Incorrect provider reimbursement

Medical coding reviews

Medical record reviews

Member plan termination

Subrogation

Managing overpayments online

The overpayment application on the Availity Essentials portal can help you manage overpayments. You can:

Manage overpayment documentation and maintain case histories electronically

Reduce overpayment resolution time by managing overpayment requests from multiple payers

Request more information about or dispute an overpayment request.

Sign up for notifications when you have an overpayment

View overpayment inventory in real-time

The overpayment application is in the Availity Essentials portal under the claims and payments section. If you do not see the application, ask your organization’s Availity administrator to grant you the “Claim Status” role.
