Yi-Shan Lee, MD appears in the CMS NPPES registry as a Hematology (Pathology) Physician provider holding MD credentials at 1 BARNES JEWISH HOSPITAL PLZ, Saint Louis, MO, 63110, with a listed phone of (314) 362-5641. NPI 1295143675 was issued on 07/29/2014.

Medicare Part D prescribing data is not currently published for this NPI, which typically means the provider either wrote fewer than 11 Part D claims in the most recent reporting year, does not participate in Medicare, or practices in a specialty that rarely prescribes outpatient drugs. Absence of prescribing data is not a quality signal, many Hematology (Pathology) Physician providers operate outside Part D entirely. On the CMS Merit-based Incentive Payment System, this provider earned a Final Score of 79.3/100 for the 2023 performance year (Quality 71.5, Cost 59.5), compared with the 83.5 average among clinicians with a measured score.

Hematology (Pathology) Physician is a narrow specialty nationwide, with 747 enrolled providers across 46 states and an average of 617 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
