ETAN MARKS, D.O. appears in the CMS NPPES registry as a Dermatopathology (Pathology) Physician provider holding D.O. credentials at 1300 NW 17TH AVE STE 130A, DELRAY BEACH, FL, 33445, with a listed phone of (866) 400-3376. NPI 1528301728 was issued on 04/05/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MARKS 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 Dermatopathology (Pathology) Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 77.2548/100 for the 2023 performance year (Quality 86.221, Cost 49.444), compared with the national average of 83.1.

Dermatopathology (Pathology) Physician is a narrow specialty nationwide, with 559 enrolled providers across 49 states and an average of 369 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.
