KATHRYN LEWIS, M.D. appears in the CMS NPPES registry as a Radiation Oncology Physician provider holding M.D. credentials at 4920 N.E. STALLILNGS DRIVE, NACOGDOCHES, TX, 75961, with a listed phone of (936) 568-3493. NPI 1215920640 was issued on 08/31/2005. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what LEWIS 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 386 prescription claims written by this provider, covering 119 Medicare beneficiaries and totaling roughly $11K in drug spend, split 13% brand-name and 87% generic by claim count, with an opioid prescribing rate of 10.6%. 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. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 81.0567/100 for the 2023 performance year (Quality 89.0377, Cost 37.44), compared with the national average of 83.1.

Radiation Oncology Physician is a mid-sized specialty nationwide, with 6,018 enrolled providers across 52 states and an average of 186 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
