The purpose of the NCCC program is to provide rapid, expert, and culturally competent clinical consultation and advice to health care team members on a wide range of HIV and HIV-related topics.

Pre-exposure prophylaxis (PrEP). Post-exposure prophylaxis (PEP). Treatment and management of Hepatitis B and C and HIV coinfections. Treatment and management of substance use disorders in people with or at risk for HIV. Perinatal HIV care and management. The NCCC provides expert consultation that demonstrates an understanding of the HIV epidemic in a variety of locations including: EHE jurisdictions. Rural areas. Areas disproportionately impacted by substance use disorders including opioid use disorder, and other co-morbidities. Communities where a large number of the people with HIV identify as a non-white racial or ethnic group. The goals for the NCCC align with those of the RWHAP Part F AETC Program, which are: Goal 1: Expand the number of health care team members providing HIV care and prevention services, including providers with different backgrounds or experiences. Goal 2: Expand the ability of health care team members to provide effective HIV care and prevention services. Goal 3: Improve health equity by integrating HIV care and prevention in primary care and other health care settings that provide services to underserved populations. Goal 4: Enhance the capacity of the AETC Program to train health care team members to serve people at risk for or with HIV.
