ANTONIO ZAMORANO, D.O. appears in the CMS NPPES registry as a Adolescent Medicine (Family Medicine) Physician provider holding D.O. credentials at 1030 S GLENDALE AVE STE 200, GLENDALE, CA, 91205, with a listed phone of (818) 850-5667. NPI 1043482060 was issued on 03/31/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ZAMORANO most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 13,972 prescription claims written by this provider, covering 850 Medicare beneficiaries and totaling roughly $1.4 million in drug spend, split 12% brand-name and 88% generic by claim count, with an opioid prescribing rate of 2.6%. These figures capture only Medicare Part D — commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Adolescent Medicine (Family Medicine) Physician is a narrow specialty nationwide, with 261 enrolled providers across 44 states and an average of 2,881 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
