EDGAR CASTILLO DANDREIS, MD appears in the CMS NPPES registry as a Medical Oncology Physician provider holding MD credentials at 6282 LINTON BLVD, DELRAY BEACH, FL, 33484, with a listed phone of (561) 495-8307. NPI 1396974135 was issued on 07/14/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CASTILLO DANDREIS 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 341 prescription claims written by this provider, covering 106 Medicare beneficiaries and totaling roughly $2.0 million in drug spend, with an opioid prescribing rate of 10.0%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 74.105/100 for the 2023 performance year (Quality 65.6301, Cost 60.0281), compared with the national average of 83.1.

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.
