Neonatal-perinatal care at Kaiser Permanente Zion Medical Center includes Philip Mattson, MD, a board-certified pediatrician and neonatologist who practices at 4647 Zion Ave, San Diego, CA 92120, in the Allied Gardens medical campus. Mattson holds NPI 1134277098, earned his medical degree from the University of Minnesota Medical School, completed his pediatric residency at the University of California San Diego Medical Center, and pursued additional training in internal medicine through Kaiser Permanente Southern California. His clinical scope covers neonatal intensive care unit management, premature infant respiratory support, jaundice phototherapy protocols, feeding tube placement, and newborn metabolic and hearing screening within the Zion campus NICU. Post-discharge follow-up for premature infants includes coordinated pediatric dental assessments as enamel hypoplasia tracking begins, with referrals managed through practices such as BRSH+FLSS Pediatric Dentistry & Orthodontics in San Carlos for early childhood dental milestones. Kaiser Permanente Zion Medical Center operates as a 253-bed facility in the 92120 ZIP with integrated laboratory, imaging, and pharmacy departments under a single electronic health record system. Allied Gardens's position along the 8 freeway gives the neonatal unit a delivery catchment that extends across Del Cerro, San Carlos, La Mesa, and the broader East County, roughly three miles northeast of SDSU. Developmental and behavioral follow-up for NICU graduates presenting with feeding difficulties, sleep regulation concerns, or early signs of developmental delay coordinates through the Kaiser system and community-based practices including Family Wellness Center in Grantville for family support services. The Zion campus maintains a 24-hour emergency department and on-site pharmacy for neonatal and pediatric needs that require after-hours intervention.
