CATHY SHRADER, MD appears in the CMS NPPES registry as a Legal Medicine provider holding MD credentials at 9131 PISCATAWAY RD STE 450, CLINTON, MD, 20735, with a listed phone of (301) 868-6700. NPI 1174615934 was issued on 09/29/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SHRADER 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 1,628 prescription claims written by this provider, covering 484 Medicare beneficiaries and totaling roughly $412K in drug spend, split 45% brand-name and 55% 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 99.153/100 for the 2023 performance year (Quality 100, Cost 97.1768), compared with the national average of 83.1.

Legal Medicine is a narrow specialty nationwide, with 1,067 enrolled providers across 51 states and an average of 2,821 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.
