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).

Houman Tamaddon, M.D. appears in the CMS NPPES registry as a Vascular Surgery Physician provider holding M.D. credentials at 1350 WALTON WAY, Augusta, GA, 30901, with a listed phone of (706) 774-7022. NPI 1609096585 was issued on 04/26/2007. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Tamaddon 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 528 prescription claims written by this provider, covering 173 Medicare beneficiaries and totaling roughly $80K in drug spend, split 16% brand-name and 84% generic by claim count, with an opioid prescribing rate of 11.6%. 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.

Vascular Surgery Physician is a narrow specialty nationwide, with 4,215 enrolled providers across 53 states and an average of 205 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.

Before you book an appointment

Use this federal record as your verification checklist, not as a recommendation.

  • Confirm the NPI record is current in the official CMS registry — providers update their own NPPES details, and moves can lag. Verify this NPI
  • Check the active license and any disciplinary history with the Georgia medical board — federal registration is not a license check. Credential verification guide
  • Weigh a second option: compare this provider with a nearby Vascular Surgery Physician peer on Medicare volume and prescribing patterns. Compare providers
