As part of the Centers for Disease Control and Prevention (CDC) Capacity Building Assistance (CBA) cooperative agreement, NASTAD released a Billing Coding Guide for HIV Prevention: PrEP, Screening, and Linkage Services. The guide, developed in collaboration with a coding consultant and the HIV Medicine Association, was updated in 2018. It assists health departments and other providers (such as health centers!) to navigate billing and reimbursement for HIV prevention services.
