JOHN STARLING, M.D. appears in the CMS NPPES registry as a MOHS-Micrographic Surgery Physician provider holding M.D. credentials at 2600 N MAYFAIR RD STE 810, MILWAUKEE, WI, 53226, with a listed phone of (414) 771-1122. NPI 1487773206 was issued on 03/29/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what STARLING 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 87 prescription claims written by this provider, covering 47 Medicare beneficiaries and totaling roughly $45K 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 82.0112/100 for the 2023 performance year (Quality 78.2022), compared with the national average of 83.1.

MOHS-Micrographic Surgery Physician is a narrow specialty nationwide, with 1,102 enrolled providers across 52 states and an average of 607 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.
