An independent medical group at 3900 Fifth Ave, Suite 200, Perlman Medical Group operates as a physician network of more than 1,000 primary care, specialty, and mental health providers serving San Diego County patients and employer members, and runs as a separate legal entity from the Perlman Clinic patient office directly downstairs. The network model means a member seeing an internist can schedule follow-up care with affiliated behavioral health providers including Dr. Kai MacDonald - Psychiatrist/Psychotherapist without rebuilding a referral chain outside the group. The Suite 200 address sits above the landmark Union Bank building corner of University and Fifth Avenue, where the group handles contracting and credentialing rather than walk-in patient visits. Members enrolled through the group reach musculoskeletal care at affiliated chiropractic offices such as Acru Health: Precision Chiropractic along with physical therapy, imaging, and labs through a single provider directory. The administrative workload here centers on contracting, credentialing, utilization review, and care coordination for the primary care, specialty, and behavioral health panels that make up a thousand-provider network - the infrastructure behind the appointment, not the appointment itself.
