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).

CRAIG BOBSON, M.D is a Adult Medicine Physician provider practicing in MANTECA, California, according to the CMS National Plan and Provider Enumeration System (NPPES). Credentials: M.D. NPI: 1790772986. This profile includes practice location, specialty classification, and organizational affiliations from the CMS provider registry.

CRAIG BOBSON, M.D appears in the CMS NPPES registry as a Adult Medicine Physician provider holding M.D credentials at 1140 NORMAN DR, MANTECA, CA, 95336, with a listed phone of (209) 825-7748. NPI 1790772986 was issued on 10/03/2005.

Medicare Part D records for calendar year 2023 show 11,528 prescription claims written by this provider, covering 732 Medicare beneficiaries and totaling roughly $1.5 million in drug spend, split 14% brand-name and 86% generic by claim count, with an opioid prescribing rate of 1.6%.

Adult Medicine Physician is a narrow specialty nationwide, with 2,481 enrolled providers across 52 states and an average of 2,807 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.
