DAVID CHOW, M.D. appears in the CMS NPPES registry as a Pain Medicine (Physical Medicine & Rehabilitation) Physician provider holding M.D. credentials at 2123 YGNACIO VALLEY ROAD, WALNUT CREEK, CA, 94598, with a listed phone of (925) 926-0195. NPI 1700823762 was issued on 05/31/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CHOW 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 157 prescription claims written by this provider, covering 70 Medicare beneficiaries and totaling roughly $13K in drug spend, split 11% brand-name and 89% generic by claim count, with an opioid prescribing rate of 42.0%. 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.

Pain Medicine (Physical Medicine & Rehabilitation) Physician is a narrow specialty nationwide, with 1,626 enrolled providers across 50 states and an average of 1,401 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.
