JOSE ALONSO ALONSO, PSYCHIATRIST MD appears in the CMS NPPES registry as a Psychiatry Physician provider holding PSYCHIATRIST MD credentials at 728 PONCE DE LEON AVE, SAN JUAN, PR, 00919, with a listed phone of (787) 754-9720. NPI 1467434548 was issued on 11/15/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ALONSO ALONSO 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 22,648 prescription claims written by this provider, covering 1,033 Medicare beneficiaries and totaling roughly $458K in drug spend. 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.

Psychiatry Physician is a high-volume specialty nationwide, with 53,104 enrolled providers across 56 states and an average of 1,038 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.
