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).

CONNOR PATTERSON, M.D. is a Procedural Dermatology Physician provider practicing in FREDERICKSBURG, Virginia, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1548475189. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry. Provider information is self-reported to CMS and updated monthly.

CONNOR PATTERSON, M.D. appears in the CMS NPPES registry as a Procedural Dermatology Physician provider holding M.D. credentials at 1985 JEFFERSON DAVIS HWY, FREDERICKSBURG, VA, 22401, with a listed phone of (540) 373-6647. NPI 1548475189 was issued on 05/14/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what PATTERSON 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 1,602 prescription claims written by this provider, covering 529 Medicare beneficiaries and totaling roughly $511K in drug spend, split 10% brand-name and 90% generic by claim count.

Procedural Dermatology Physician is a narrow specialty nationwide, with 679 enrolled providers across 48 states and an average of 664 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.
