85.574/100 MIPS final score — 2.5 pts above the 83.1 national average
Quality, Cost, Promoting Interoperability, and Improvement Activities composite score for the 2023 performance year. Specialty: Surgery Physician. Quality dim: 82.9299. Cost dim: 65.3738.
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).
CARTER FREIBURG, M.D. appears in the CMS NPPES registry as a Surgery Physician provider holding M.D. credentials at 520 UPPER CHESAPEAKE DR, BEL AIR, MD, 21014, with a listed phone of (410) 879-2006. NPI 1720102288 was issued on 03/19/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what FREIBURG 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 146 prescription claims written by this provider, covering 70 Medicare beneficiaries and totaling roughly $47K in drug spend, split 49% brand-name and 51% generic by claim count. 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 85.574/100 for the 2023 performance year (Quality 82.9299, Cost 65.3738), compared with the national average of 83.1.
Surgery Physician is a mid-sized specialty nationwide, with 36,191 enrolled providers across 56 states and an average of 169 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.
