FRANK MAYER appears in the CMS NPPES registry as a Emergency Medicine Physician provider at 640 S STATE ST, DOVER, DE, 19901, with a listed phone of (302) 674-4700. NPI 1144857632 was issued on 03/24/2020. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what MAYER 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 135 prescription claims written by this provider, covering 99 Medicare beneficiaries and totaling roughly $4K in drug spend, split 8% brand-name and 92% generic by claim count, with an opioid prescribing rate of 12.6%. 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 98.0348/100 for the 2023 performance year (Quality 88.5219), compared with the national average of 83.1.

Emergency Medicine Physician is a high-volume specialty nationwide, with 64,398 enrolled providers across 56 states and an average of 352 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.

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.
