Overview

Billing in Infectious Disease

A practical view of what makes this specialty unique.

Infectious Disease (ID) billing involves managing complex, often chronic conditions like HIV/AIDS, hepatitis, and antibiotic-resistant infections, with a heavy emphasis on infusion therapies and careful medication management. Our ID billing service is designed to handle these complexities, from prolonged E&M consultations to the intricate coding and prior authorization requirements for long-term antibiotic and antiviral infusions. We ensure accurate reimbursement for all services, allowing you to focus on combating serious infections.

Coding

Coding complexities we watch closely

Modifier usage, documentation rules, and specialty-specific payer edits.

Complexity checklist
  • Infusion coding based on duration and drug type (chemotherapy vs. non-chemotherapy).
  • Coding for prolonged services (99417) when extensive time is spent with a patient.
  • Correct coding for HIV testing and counseling (G0432, G0433).
  • Billing for resistance testing (87900-87904).
Denial triggers

Insufficient documentation for high-level E&M or prolonged services.

Missing prior authorization for long-term IV antibiotics.

Incorrect coding of infusion time or units of drug.

Billing for drugs not covered under medical benefit (e.g., some oral antivirals).

Lack of medical necessity for specialized ID testing.
