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 Molecular Genetics 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).

John Howe, PHD appears in the CMS NPPES registry as a Clinical Molecular Genetics Physician provider holding PHD credentials at 333 CEDAR ST, New Haven, CT, 06520, with a listed phone of (203) 737-4237. NPI 1598898900 was issued on 03/14/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Howe 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 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 Clinical Molecular Genetics Physician providers operate outside Part D entirely.

Clinical Molecular Genetics Physician is a narrow specialty nationwide, with 105 enrolled providers across 26 states and an average of 268 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.

  • Confirm the NPI record is current in the official CMS registry, providers update their own NPPES details, and moves can lag. Verify this NPI
  • Check the active license and any disciplinary history with the Connecticut medical board, federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Clinical Molecular Genetics Physician peer on Medicare volume and prescribing patterns. Compare providers
