6. Coordinate with Internal Billing Teams
They communicate with billing and coding teams to fix errors related to CPT codes, modifiers, or patient demographics that may cause rejections or payment delays.
7. Meet Daily Call and Productivity Targets
Medical billing companies set daily KPIs for AR callers. These include the number of claims followed up, resolution rate, and call documentation accuracy.
8. Address Patient Billing Queries
AR callers may interact with patients to explain balances, insurance denials, or coverage issues in some cases. This requires empathy and clear communication with the other people.
