ESTHER AMADOR-DEL VALLE, D.O. appears in the CMS NPPES registry as a Internal Medicine Physician provider holding D.O. credentials at 4300 ALTON RD, MIAMI BEACH, FL, 33140, with a listed phone of (305) 481-9776. NPI 1043475684 was issued on 07/23/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what AMADOR-DEL VALLE 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 prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal — many Internal Medicine Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 91.7963/100 for the 2023 performance year (Quality 67.7709, Cost 98.4077), compared with the national average of 83.1.

Internal Medicine Physician is a high-volume specialty nationwide, with 172,858 enrolled providers across 56 states and an average of 2,716 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.
