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).

WEI SONG, M.D., PHD appears in the CMS NPPES registry as a Molecular Genetic Pathology (Medical Genetics) Physician provider holding M.D., PHD credentials at 200 W ARBOR DR, SAN DIEGO, CA, 92103, with a listed phone of (800) 926-8273. NPI 1306164157 was issued on 05/04/2010. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what SONG 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 Molecular Genetic Pathology (Medical Genetics) Physician providers operate outside Part D entirely.

Molecular Genetic Pathology (Medical Genetics) Physician is a narrow specialty nationwide, with 21 enrolled providers across 14 states, 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.
