ROBERT BRUN, PA appears in the CMS NPPES registry as a Physician Assistant provider holding PA credentials at 102 GREGOR MENDEL CIR, GREENWOOD, SC, 29646, with a listed phone of (864) 229-2663. NPI 1134407398 was issued on 07/21/2011. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what BRUN 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 309 prescription claims written by this provider, covering 226 Medicare beneficiaries and totaling roughly $7K in drug spend, split 4% brand-name and 96% generic by claim count, with an opioid prescribing rate of 16.2%. 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 96.0864/100 for the 2023 performance year (Quality 92.1728), compared with the national average of 83.1.

Physician Assistant is a high-volume specialty nationwide, with 149,975 enrolled providers across 56 states and an average of 790 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
