NATHAN HASHIMOTO, M.D. appears in the CMS NPPES registry as a Hospice and Palliative Medicine (Family Medicine) Physician provider holding M.D. credentials at 2201 N LAKEWOOD BLVD # D629, LONG BEACH, CA, 90815, with a listed phone of (000) 000-0000. NPI 1316998248 was issued on 05/15/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what HASHIMOTO 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 650 prescription claims written by this provider, covering 186 Medicare beneficiaries and totaling roughly $28K in drug spend, split 8% brand-name and 92% generic by claim count. 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 76.2631/100 for the 2023 performance year (Quality 62.7438, Cost 59.2967), compared with the national average of 83.1.

Hospice and Palliative Medicine (Family Medicine) Physician is a narrow specialty nationwide, with 784 enrolled providers across 51 states and an average of 2,070 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.
