PETER ROTHSTEIN, M.D. appears in the CMS NPPES registry as a Clinical Cardiac Electrophysiology Physician provider holding M.D. credentials at 10012 KENNERLY RD STE 300, SAINT LOUIS, MO, 63128, with a listed phone of (314) 692-2807. NPI 1598183543 was issued on 04/06/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what ROTHSTEIN 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 142 prescription claims written by this provider, covering 85 Medicare beneficiaries and totaling roughly $25K in drug spend, split 25% brand-name and 75% 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 96.3686/100 for the 2023 performance year (Quality 86.2339), compared with the national average of 83.1.

Clinical Cardiac Electrophysiology Physician is a narrow specialty nationwide, with 1,570 enrolled providers across 52 states and an average of 1,596 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
