Infectious Disease Billing Services for OPAT, HIV Care & Antimicrobial Infusion Coding
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.

HIV/AIDS Comprehensive Care Billing
Accurate billing for HIV management visits, viral load monitoring (87536), CD4 testing (86360), resistance testing (87900-87904), and PrEP/PEP counseling with Medicare and Ryan White program compliance.

Precise IVIG billing (J1459, J1460) with weight-based unit calculation, prior authorization management, and infusion time-based administration coding for ID conditions including CIDP, hypogammaglobulinemia, and severe infections.
Infectious Disease Coding Complexities That Trigger Claim Denials
From prolonged service time documentation to OPAT re-authorization cycles, these are the precision coding areas that most often determine ID practice reimbursement.
- 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).
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.
