Quality, Cost, Promoting Interoperability, and Improvement Activities composite score for the 2023 performance year. Specialty: Geriatric Psychiatry Physician. Quality dim: 84.7241. Cost dim: 45.013.
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).
GEORGE GROSSBERG, MD appears in the CMS NPPES registry as a Geriatric Psychiatry Physician provider holding MD credentials at 1438 S GRAND BLVD, SAINT LOUIS, MO, 63104, with a listed phone of (314) 977-4829. NPI 1033135991 was issued on 07/14/2006. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what GROSSBERG 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 records for calendar year 2023 show 2,954 prescription claims written by this provider, covering 254 Medicare beneficiaries and totaling roughly $446K in drug spend. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 88.9211/100 for the 2023 performance year (Quality 84.7241, Cost 45.013), compared with the national average of 83.1.
Geriatric Psychiatry Physician is a narrow specialty nationwide, with 785 enrolled providers across 46 states and an average of 1,586 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.
