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).

FABRICIO ALARCON, M.D. is a Internal Medicine Physician provider practicing in GEORGETOWN, Delaware, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D.. NPI: 1134184278. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

FABRICIO ALARCON, M.D. appears in the CMS NPPES registry as a Internal Medicine Physician provider holding M.D. credentials at 2 LEE AVE UNIT 103, GEORGETOWN, DE, 19947, with a listed phone of (302) 856-4092. NPI 1134184278 was issued on 04/20/2006.

Medicare Part D records for calendar year 2023 show 19,872 prescription claims written by this provider, covering 915 Medicare beneficiaries and totaling roughly $1.7 million in drug spend, split 11% brand-name and 89% generic by claim count, with an opioid prescribing rate of 1.1%.

Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating.
