BENJAMIN DIRKX, D.O. appears in the CMS NPPES registry as a Physical Medicine & Rehabilitation Physician provider holding D.O. credentials at 401 E CARRILLO ST, SANTA BARBARA, CA, 93101, with a listed phone of (805) 563-3307. NPI 1679875389 was issued on 12/01/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what DIRKX 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 1,883 prescription claims written by this provider, covering 304 Medicare beneficiaries and totaling roughly $82K in drug spend, split 4% brand-name and 96% generic by claim count, with an opioid prescribing rate of 36.7%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 67.9536/100 for the 2023 performance year (Quality 40.617, Cost 35.895), compared with the national average of 83.1.

Physical Medicine & Rehabilitation Physician is a mid-sized specialty nationwide, with 15,306 enrolled providers across 54 states and an average of 781 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline. Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. 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.
