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).

GREGG WELSH, DDS appears in the CMS NPPES registry as a Oral and Maxillofacial Pathology Dentistry provider holding DDS credentials at 38 SOUTH LA CUMBRE RD, SANTA BARBARA, CA, 93105, with a listed phone of (805) 692-8500. NPI 1790994341 was issued on 05/21/2007.

Medicare Part D records for calendar year 2023 show 216 prescription claims written by this provider, covering 56 Medicare beneficiaries and totaling roughly $1K in drug spend, with an opioid prescribing rate of 16.2%. 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.

Oral and Maxillofacial Pathology Dentistry is a narrow specialty nationwide, with 690 enrolled providers across 48 states and an average of 303 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.
