WALTER D'COSTA, D.P.M. appears in the CMS NPPES registry as a Radiology Podiatrist provider holding D.P.M. credentials at 2281 CLEVELAND AVE, SANTA ROSA, CA, 95403, with a listed phone of (707) 544-3337. NPI 1548336605 was issued on 11/28/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what D'COSTA 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 594 prescription claims written by this provider, covering 196 Medicare beneficiaries and totaling roughly $12K in drug spend, with an opioid prescribing rate of 5.7%. 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 0/100 for the 2023 performance year (Quality 0), compared with the national average of 83.1.

Radiology Podiatrist is a narrow specialty nationwide, with 23 enrolled providers across 14 states and an average of 302 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.
