Utilize AdvancedMD daily to work assigned aging reports, worklists, and claim hold queues efficiently
Document precise, professional accounts receivable notes regarding payer status, claim refilings, and expected resolution timelines
Collaborate with internal pathology coding and billing team members to resolve systemic billing blockers
