ROBERTO ALDARONDO, M.D. appears in the CMS NPPES registry as a Contractor provider holding M.D. credentials at 30 CALLE PROGRESO, AGUADILLA, PR, 00603, with a listed phone of (787) 891-3838. NPI 1437130549 was issued on 11/07/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ALDARONDO 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 6,908 prescription claims written by this provider, covering 309 Medicare beneficiaries and totaling roughly $172K in drug spend, split 7% brand-name and 93% generic by claim count, with an opioid prescribing rate of 0.5%. 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.

Contractor is a mid-sized specialty nationwide, with 8,680 enrolled providers across 54 states and an average of 927 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.
