YUN KYOUNG TIGER, M.D appears in the CMS NPPES registry as a Hematology (Internal Medicine) Physician provider holding M.D credentials at 200 1ST ST SW, ROCHESTER, MN, 55905, with a listed phone of (507) 284-2511. NPI 1578096269 was issued on 04/10/2017. Because NPPES data is self-reported by the provider and refreshed monthly, the address, phone, and specialty reflect what TIGER 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 46 prescription claims written by this provider, covering 18 Medicare beneficiaries and totaling roughly $226K in drug spend, split 33% brand-name and 67% 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.

Hematology (Internal Medicine) Physician is a narrow specialty nationwide, with 1,436 enrolled providers across 50 states and an average of 693 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.
