Part D of the Ryan White HIV/AIDS Treatment Modernization Act of 2006 provides family centered care involving outpatient or ambulatory care (directly or through contracts) for women, infants, children, and youth with HIV/AIDS.
Grantees are expected to provide care, treatment, and support services or create a network of medical and social service providers, who collaborate to supply services.

Part D funds the following services:

• Family-centered primary and specialty medical care
  
• Support services
  
• Logistical support and coordination.

In addition grantees are to educate clients about research and research opportunities and inform all clients about the benefits of participation, and how to enroll in research.

The Title IV programs (now referred to as Part D) started in 1988 as the Pediatric AIDS Demonstration Projects. The projects originally served infected infants and children, infected pregnant women and their families. They provided supportive care to families to help infected children receive medical care. Beginning in 1994, Congress funded these projects under Title IV of the Ryan White Comprehensive AIDS Resource Emergency (CARE) Act. In 1999, in response to the alarming growth of HIV infected youth being identified, the HIV/AIDS Bureau (HAB) funded a Youth Initiative, which currently supports 17 youth specific programs across the nation. In 2006, Congress funded the Part D programs under Title XXVI of the Public Health Service Act as amended by the Ryan White HIV/AIDS Treatment Modernization Act of 2006.

The Part D program has improved access to a comprehensive system of health and social services for populations least able to cope with HIV/AIDS.

The FY 2007 appropriation was $70.6 million. Since 1994, the Part D Program and Pediatric AIDS Demonstration Program have provided more than $681.6 million in funding to States and communities.
