Pre-Exposure Prophylaxis (PrEP), Post-Exposure Prophylaxis (PEP), and Other HIV Prevention Strategies: Billing and Coding Guide

Developed by NASTAD, updated in 2023

Health departments and other medical providers are billing Medicaid, Medicare, and private insurers for services related to HIV prevention. The counseling services needed for the treatment and discussion of lab tests are intensive. This guide describes the procedure and diagnosis codes that are accepted by public and private insurance, along with specific requirements for some Current Procedural Terminology (CPT®) billing codes. It also describes some of the challenges in obtaining reimbursement for testing, counseling, linkage to care, and adherence services.

The goal of this guide is to provide up-to-date information and best practices for coding, billing, and denial resolution for PrEP and PEP services. Health department staff are encouraged to share this resource with grantees, community partners, and other health care providers billing for HIV prevention services.
