KALVIN LUNG, M.D., M.SC. appears in the CMS NPPES registry as a Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician provider holding M.D., M.SC. credentials at 675 N ST CLAIR ST 17TH FLOOR, CHICAGO, IL, 60611, with a listed phone of (312) 926-4230. NPI 1134735962 was issued on 09/17/2020.

Medicare Part D records for calendar year 2023 show 19 prescription claims written by this provider, covering 11 Medicare beneficiaries and totaling roughly $820 in drug spend. 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 94.1036/100 for the 2023 performance year (Quality 82.5938), compared with the national average of 83.1.

Thoracic Surgery (Cardiothoracic Vascular Surgery) Physician is a mid-sized specialty nationwide, with 5,062 enrolled providers across 52 states and an average of 128 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
