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).

KARLYN HOWELL is a Maternal Newborn Registered Nurse provider practicing in FORT WAYNE, Indiana, according to the CMS National Plan and Provider Enumeration System (NPPES). NPI: 1164182432.

KARLYN HOWELL appears in the CMS NPPES registry as a Maternal Newborn Registered Nurse provider at 1234 E DUPONT RD STE 1, FORT WAYNE, IN, 46825, with a listed phone of (260) 425-6390. NPI 1164182432 was issued on 12/28/2021.

Maternal Newborn Registered Nurse is a narrow specialty nationwide, with 811 enrolled providers across 50 states and an average of 290 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.
