MAKARDHWAJ SHRIVASTAVA, MBBS appears in the CMS NPPES registry as a Medical Oncology Physician provider holding MBBS credentials at 625 N 6TH ST, PHOENIX, AZ, 85004, with a listed phone of (602) 406-8222. NPI 1871844258 was issued on 09/26/2012. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SHRIVASTAVA 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 214 prescription claims written by this provider, covering 47 Medicare beneficiaries and totaling roughly $608K in drug spend, split 29% brand-name and 71% 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.

Medical Oncology Physician is a narrow specialty nationwide, with 3,792 enrolled providers across 53 states and an average of 689 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.
