Physician assistant Billie P Neal practices at Kaiser Permanente Zion Medical Center in Allied Gardens, San Diego, from the primary care clinic at 4647 Zion Ave in the 92120 ZIP. Her NPI is 1083730238, and she carries board certification under the physician assistant taxonomy, practicing within Kaiser's integrated model where PAs manage their own patient panels under physician oversight. The Kaiser Zion campus houses primary care, specialty medicine, a 24-hour emergency department, inpatient beds, surgical suites, and a CARF-accredited rehabilitation unit. Integrative approaches that complement conventional primary care operate nearby, and EverThrive Health in College Area offers acupuncture and naturopathic services for patients supplementing their Kaiser treatment plans. Allied Gardens' position between the I-8 freeway and Waring Road's neighborhood business strip means the Zion campus draws its patient population from the residential streets east of Zion Avenue, the Orcutt Avenue corridor, and the mid-century housing tracts that define this sub-community. Kaiser Permanente's closed-system pharmacy model means prescriptions written by Neal fill at the Zion campus dispensary under Pharmacy NPI 1396893111, and lab orders process through the building's own clinical laboratory. Physical therapy cases from her panel connect to Kaiser's rehabilitation department and extend to area providers including San Diego Physical Therapy in Grantville for patients carrying non-Kaiser coverage. The Zion facility's National Provider Identifier is 1013062769, registered under Kaiser Foundation Hospitals with a California facility license number PHY 18690 for the on-site pharmacy.
