Board certification
Not published by CMS
CMS does not publish a per-provider board-certification field in NPPES. PlainDoctor does not have a reliable per-specialty certification rate to show for Clinical Neurophysiology Physician. Verify directly:
How MIPS and board certification work
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).
Mahmood Nasir, MD appears in the CMS NPPES registry as a Clinical Neurophysiology Physician provider holding MD credentials at 512 MARKET ST, Sunbury, PA, 17801, with a listed phone of (570) 286-9878. NPI 1497738934 was issued on 11/29/2005.
Medicare Part D records for calendar year 2023 show 2,275 prescription claims written by this provider, covering 141 Medicare beneficiaries and totaling roughly $386K in drug spend, split 21% brand-name and 79% generic by claim count, with an opioid prescribing rate of 56.3%.
Clinical Neurophysiology Physician is a narrow specialty nationwide, with 639 enrolled providers across 50 states and an average of 1,523 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.
