RYAN CONNOLLY, D.O. appears in the CMS NPPES registry as a Internal Medicine Physician provider holding D.O. credentials at 316 CALHOUN ST, CHARLESTON, SC, 29401, with a listed phone of (843) 724-2450. NPI 1659613297 was issued on 03/21/2013. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what CONNOLLY 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 334 prescription claims written by this provider, covering 104 Medicare beneficiaries and totaling roughly $38K in drug spend, split 20% brand-name and 80% 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 73.2438/100 for the 2023 performance year (Quality 73.0442, Cost 59.5152), compared with the national average of 83.1.

Internal Medicine Physician is a high-volume specialty nationwide, with 172,858 enrolled providers across 56 states and an average of 2,716 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.
