The National Clinician Consultation Center (NCCC) Offers Free and Confidential Resources for Clinicians

The National Clinician Consultation Center (NCCC) offers free, confidential point-of-care tele-consultation to any U.S. based clinicians seeking guidance on substance use evaluation and management, hepatitis C, and HIV/AIDS prevention and management. For 30 years, the NCCC has established itself nationally as a consultation and educational resource that helps clinicians of all experience levels and practice settings.

Through its six tele-consultation lines, the NCCC aims to be an easily accessible “one-stop shop” in supporting the delivery of care that is evidence-informed, person-centered, and promotes health equity:

  • The Substance Use Warmline (855-300-3595) offers guidance on substance use evaluation, management, overdose prevention strategies, and treatment of co-morbid conditions, including chronic pain and co-occurring psychiatric disorders.
  • The HIV/AIDS Warmline (800-933-3413) provides decision support on questions about HIV antiretroviral medications, drug resistance, testing, and HIV/HCV co-infection.
  • The Perinatal HIV/AIDS Hotline (888-448-8765) addresses topics regarding the care of HIV‐positive pregnant people and their infants.
  • The Hepatitis C Warmline (844-437-4636) offers advice on screening, staging, monitoring, and treatment for hepatitis C.
  • The PrEPline (855-448-7737) provides guidance on the initiation and management of pre-exposure prophylaxis as an HIV prevention option.
  • The PEPline (888-448-4911) offers advice on bloodborne pathogen exposure evaluation and management, including occupational and non-occupational exposures to HIV, hepatitis B and

All lines are staffed by a multidisciplinary team of expert primary care and specialist-trained physicians, advanced practice nurses, and specialty clinical pharmacists with over 500 years of collective professional experience across these fields. The NCCC has received consultation requests from clinicians of varied backgrounds and experience levels, including nurses, physician assistants, pharmacists, and primary care as well as specialty physicians.  The NCCC has assisted providers in rural and urban locations across the U.S.  Callers rate NCCC consultations very highly on usefulness and quality, and also note the NCCC’s value and role in helping to achieve positive patient outcomes. NCCC consultants are available Monday through Friday, 9 AM to 8 PM Eastern Time (with the exception of the Perinatal HIV Hotline which is available 24/7).
