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).

ALEEN SHAH, PA-C is a Addiction Psychiatry Physician provider practicing in CRYSTAL LAKE, Illinois, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: PA-C. NPI: 1942612668. 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.

ALEEN SHAH, PA-C appears in the CMS NPPES registry as a Addiction Psychiatry Physician provider holding PA-C credentials at 145 S VIRGINIA ST, CRYSTAL LAKE, IL, 60014, with a listed phone of (815) 444-9999. NPI 1942612668 was issued on 05/29/2014.

Medicare Part D records for calendar year 2023 show 1,568 prescription claims written by this provider, covering 94 Medicare beneficiaries and totaling roughly $171K in drug spend, split 6% brand-name and 94% generic by claim count.

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.
