• Coordinate with our billing and clinical teams to resolve discrepancies and verify corrections.
• Develop and maintain payer-specific billing guides and staff checklists.
• Maintain patient confidentiality and follow company privacy and security procedures.

• Applied Behavior Analysis (ABA) billing experience strongly preferred.
• Ability to independently research and interpret payer-specific requirements.
• Strong attention to detail, written English, and organizational skills.
