Before you mail it
- Check the back of the ID card. Humana Medicaid plans and some group plans print their own address. If the card shows a different box, use the card.
- Go electronic if you can. Payer ID 61101 through Availity Essentials or your clearinghouse. The acceptance report is your proof of timely filing.
- Corrected claim? Send it electronically with frequency code 7 and the original claim number. It still has to fit inside the original filing limit.
- Keep the tracking number for anything you mail.
Send us the list: payer, date of service, denial code and amount. No patient names needed. We will tell you which claims can still be fixed, which need an appeal, and which deadlines are close.
