> Denial triage and appeal drafting for medical billing companies, practices, and utilization review teams. An 835 remittance file becomes a prioritized denial worklist, and the denials worth appealing become draft appeal letters and prior authorization requests.

## About EZAppeal

EZAppeal reads an 835 remittance file and sorts every denial by what to do next: appeal, corrected claim, rebill to the right payer, peer-to-peer, bill the patient, or not worth appealing. For the denials worth appealing, it drafts the letter from the denial and the clinical notes. It looks up the payer's published medical policy when one is on file, argues general clinical criteria (labeled as such) when not, and audits the draft's citations against the sources it was drafted from. EZAppeal never sends anything to a payer: the billing team reviews each letter and sends it.

## Key Facts

- Triages 835 (ERA) remittance files into a prioritized denial worklist; triage is free
- Drafts appeal letters and prior authorization requests
- Covers all major payers: UnitedHealthcare, Blue Cross Blue Shield, Aetna, Cigna, Humana, Medicare, Medicaid, Anthem
- Cites the payer's published medical policy when one is on file, and general criteria, labeled as such, when not
- Supports both outpatient and inpatient appeals
- HIPAA-compliant platform, with a Business Associate Agreement on every account
- Website: https://www.ezappeal.com

## How It Works

1. Upload an 835 remittance file for a prioritized denial worklist, or paste a single denial letter and the clinical notes
2. EZAppeal identifies the payer, procedure, and denial reason, and says whether an appeal is the right move
3. It matches the clinical evidence to the payer's medical policy criteria when a policy is on file
4. It drafts the appeal letter and audits its citations against the sources it was drafted from
5. The billing team reviews the letter and sends it on practice letterhead
