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 Neurological Surgery Physician. Verify directly:

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).

Troy Dawley, DO appears in the CMS NPPES registry as a Neurological Surgery Physician provider holding DO credentials at 222 E MEDICAL LN STE 100, West Columbia, SC, 29169, with a listed phone of (803) 935-8410. NPI 1154738326 was issued on 07/18/2014. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Dawley most recently submitted to CMS rather than a vetted directory listing, which is why patients should always confirm the practice is still at this location before scheduling.

Medicare Part D records for calendar year 2023 show 753 prescription claims written by this provider, covering 248 Medicare beneficiaries and totaling roughly $10K in drug spend, split 1% brand-name and 99% generic by claim count, with an opioid prescribing rate of 33.1%. These figures capture only Medicare Part D, commercial insurance, Medicaid, and cash-pay prescriptions are not included, and any drug-beneficiary cell under 11 is suppressed by CMS for patient privacy.

Neurological Surgery Physician is a mid-sized specialty nationwide, with 8,100 enrolled providers across 53 states and an average of 181 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.
