RICHARD LEWIS, M.D. appears in the CMS NPPES registry as a Neuromuscular Medicine (Psychiatry & Neurology) Physician provider holding M.D. credentials at 4915 NORTON HEALTHCARE BLVD STE 301, LOUISVILLE, KY, 40241, with a listed phone of (502) 394-6390. NPI 1710372396 was issued on 04/01/2015. 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 945 prescription claims written by this provider, covering 188 Medicare beneficiaries and totaling roughly $1.2 million in drug spend, split 16% brand-name and 84% generic by claim count, with an opioid prescribing rate of 1.2%. 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 100/100 for the 2023 performance year, compared with the national average of 83.1.

Neuromuscular Medicine (Psychiatry & Neurology) Physician is a narrow specialty nationwide, with 336 enrolled providers across 44 states and an average of 931 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
