The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

ALEXANDER CARTRON, MD is a Dermatology Physician provider practicing in PHILADELPHIA, Pennsylvania, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: MD. NPI: 1639756281. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

ALEXANDER CARTRON, MD appears in the CMS NPPES registry as a Dermatology Physician provider holding MD credentials at 1528 WALNUT ST STE 950, PHILADELPHIA, PA, 19102, with a listed phone of (267) 273-1196. NPI 1639756281 was issued on 03/28/2021.

Medicare Part D records for calendar year 2023 show 492 prescription claims written by this provider, covering 164 Medicare beneficiaries and totaling roughly $518K in drug spend, split 14% brand-name and 86% generic by claim count.

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.
