A hospital-based infusion center inside UC San Diego Health's six-floor, 250,000-square-foot McGrath Outpatient Pavilion at 4250 First Avenue Suite 40, UC San Diego Health Infusion Therapy – Hillcrest delivers intravenous chemotherapy, biologics, and IV antimicrobials under academic-medical-center supervision. The pavilion sits directly adjacent to Hillcrest Medical Center at UC San Diego Health, which keeps infusion patients a short corridor away from the hospital for escalation of care during a reaction. Treatments include IVIG, monoclonal antibody therapy, post-transplant medications, iron infusions, and outpatient IV antibiotic regimens. Hospital-based billing runs through the facility-fee structure rather than a freestanding outpatient code, so insurance preauthorization is part of the intake workflow. Referrals route in from specialty and primary care providers including UC San Diego Health Internal Medicine – Hillcrest when chronic-condition patients need scheduled IV therapy. The most complex case the center handles is a multi-hour chemotherapy regimen staged with premedication, active infusion, and post-infusion monitoring for oncology patients referred from the Moores Cancer Center network.
