DANIEL AYALA-ORTIZ appears in the CMS NPPES registry as a Student in an Organized Health Care Education/Training Program provider at 401 BICENTENNIAL WAY, SANTA ROSA, CA, 95403, with a listed phone of (707) 391-8779. NPI 1578918744 was issued on 04/25/2016. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what AYALA-ORTIZ 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 2,827 prescription claims written by this provider, covering 462 Medicare beneficiaries and totaling roughly $148K in drug spend, split 7% brand-name and 93% 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.

Student in an Organized Health Care Education/Training Program is a high-volume specialty nationwide, with 331,761 enrolled providers across 55 states and an average of 459 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
