MARSHALL ALLEN appears in the CMS NPPES registry as a Case Manager/Care Coordinator provider at 650 HIGH ST, DANVILLE, KY, 40422, with a listed phone of (859) 236-2726. NPI 1851576920 was issued on 01/08/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ALLEN 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 Case Manager/Care Coordinator providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 60.2866/100 for the 2023 performance year (Quality 18.8133, Cost 99.7976), compared with the national average of 83.1.

Case Manager/Care Coordinator is a high-volume specialty nationwide, with 160,120 enrolled providers across 54 states and an average of 859 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.
