BROCK COOKMAN, D.O. appears in the CMS NPPES registry as a Internal Medicine Physician provider holding D.O. credentials at 1600 S 48TH ST, LINCOLN, NE, 68506, with a listed phone of (402) 483-3333. NPI 1427286681 was issued on 06/26/2009. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what COOKMAN 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 3,959 prescription claims written by this provider, covering 528 Medicare beneficiaries and totaling roughly $392K in drug spend, split 13% brand-name and 87% generic by claim count. 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 84.954/100 for the 2023 performance year (Quality 94.7896, Cost 55.0569), 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.
