Step-by-Step Instructions for Submitting Physical Documentation
Submitting paperwork through postal mail requires strict adherence to formatting and tracking protocols to ensure accountability. Follow these sequential steps when sending physical correspondence to any Horizon address:
- Verify the Form Version: Ensure you are using the official 2026 version of any claim form, appeal application, or enrollment document. Outdated forms are automatically rejected.
- Include Identifying Information: Clearly write the member identification number, subscriber full name, and date of birth on the top right corner of every single page submitted.
- Organize Supporting Evidence: If submitting medical records for an appeal, arrange documents chronologically with a cover sheet detailing the total page count.
- Choose Tracked Shipping: For time-sensitive legal notices, appeals, or high-dollar claim disputes, utilize certified mail with return receipt requested through the United States Postal Service (USPS) or a comparable private courier.
- Retain Copies: Always keep a complete physical or digital copy of everything mailed, along with your delivery tracking receipt, until the matter is officially resolved by Horizon.
Important Operational Note: Digital Alternatives Preferred: Whenever possible, members and providers are strongly encouraged to upload documents directly through the secure Horizon Blue member portal or provider portal. Digital submissions bypass mailroom processing times and provide instant electronic confirmation of receipt, drastically reducing the risk of lost paperwork.
