OPAT Billing Services: Outpatient Parenteral Antibiotic Therapy Claims Management

Frequently Asked Questions
How do the recent E/M (Evaluation & Management) changes and new codes affect infectious disease billing and documentation?
Infectious disease specialists provide many cognitive/consultative services (E/M-type). The recent CMS/CPT revisions (including G2211, add-on codes such as G0545, and updated documentation rules) require practices to update their documentation practices, including medical decision-making, time, and complexity, to avoid claims being undervalued or denied.
How can outsourcing infectious disease billing improve revenue?
When you outsource infectious disease billing to a team specializing in ID, you capture revenue in three specific areas that generalist billers miss: (1) OPAT and anti-infective J-code accuracy — including wastage documentation that recovers the full cost of partially used drug vials; (2) inpatient consultation coding at the correct complexity level for ID-specific cognitive work; and (3) G2211 add-on code capture on established patient visits. ID-specialized outsourced billing typically recovers 15–20% more revenue than generalist billing teams managing the same claim volume.
How do you improve reimbursement for OPAT and antibiotic therapy?
We optimize OPAT billing by coordinating E/M visits, infusion administration (CPT 96365–96366), and anti-infective drug J-code billing with accurate unit calculations and JW/JZ wastage documentation. This ensures you capture the full reimbursement for high-cost IV antibiotics while reducing denials and billing gaps across care settings.
Do you handle HIV and sepsis coding compliance?
Yes, we specialize in HIV and sepsis billing compliance. We ensure accurate E/M coding for HIV management, correct lab billing (CD4, viral load), and proper coordination with Ryan White Program requirements. For sepsis, we apply precise ICD-10 coding and severity sequencing (A41.x, R65.20, R65.21) to support medical necessity, prevent audits, and maximize reimbursement.
