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).

ELIZABETH KORN, APRN, LMFT appears in the CMS NPPES registry as a Marriage & Family Therapist provider holding APRN, LMFT credentials at 56 FRANKLIN ST, WATERBURY, CT, 06706, with a listed phone of (203) 709-6000. NPI 1649495722 was issued on 04/16/2007.

Marriage & Family Therapist is a high-volume specialty nationwide, with 87,139 enrolled providers across 55 states and an average of 217 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.
