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.
Refund checks for overpayments can be mailed to:

Emergency room services

If you have any specific questions or concerns pertaining to this, please contact your Provider Education and Outreach Representative.
