Stephen Duncan, MD appears in the CMS NPPES registry as a Adult Reconstructive Orthopaedic Surgery Physician provider holding MD credentials at 740 S LIMESTONE, Lexington, KY, 40536, with a listed phone of (859) 323-5533. NPI 1578726873 was issued on 07/07/2008. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what Duncan 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 359 prescription claims written by this provider, covering 133 Medicare beneficiaries and totaling roughly $6K in drug spend, with an opioid prescribing rate of 25.1%. 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 100/100 for the 2023 performance year, compared with the national average of 83.1.

Adult Reconstructive Orthopaedic Surgery Physician is a narrow specialty nationwide, with 1,245 enrolled providers across 51 states and an average of 493 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
