CRISTINA ORTIZ-DIAZ, DMD, MSD appears in the CMS NPPES registry as a Oral and Maxillofacial Surgery (Dentist) provider holding DMD, MSD credentials at 36 CARR 2 STE 301, VEGA ALTA, PR, 00692, with a listed phone of (787) 883-6234. NPI 1306256276 was issued on 05/01/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ORTIZ-DIAZ 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 1,716 prescription claims written by this provider, covering 505 Medicare beneficiaries and totaling roughly $11K in drug spend, split 2% brand-name and 98% generic by claim count, with an opioid prescribing rate of 2.8%. 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.

Oral and Maxillofacial Surgery (Dentist) is a mid-sized specialty nationwide, with 7,631 enrolled providers across 52 states and an average of 378 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
