MARK BALL, MD appears in the CMS NPPES registry as a Urology Physician provider holding MD credentials at 10 CENTER DRIVE RM 2-5942, BETHESDA, MD, 20892, with a listed phone of (240) 858-3700. NPI 1275783375 was issued on 09/25/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BALL 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 Urology Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 86.7926/100 for the 2023 performance year (Quality 86.467, Cost 72.0084), compared with the national average of 83.1.

Urology Physician is a mid-sized specialty nationwide, with 13,350 enrolled providers across 54 states and an average of 1,280 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.
