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 Neurology with Special Qualifications in Child Neurology 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).

Karla Cay-Martinez, M.D. appears in the CMS NPPES registry as a Neurology with Special Qualifications in Child Neurology Physician provider holding M.D. credentials at CARR 172, SALIDA 21 DE LA PR 52, SUITE D500, Caguas, PR, 00726, with a listed phone of (787) 653-0550. NPI 1396127551 was issued on 06/24/2015.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal, many Neurology with Special Qualifications in Child Neurology Physician providers operate outside Part D entirely.

Neurology with Special Qualifications in Child Neurology Physician is a narrow specialty nationwide, with 1,819 enrolled providers across 51 states and an average of 359 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.
