Marie Chun Yu, BSN-RN/PRESIDENT appears in the CMS NPPES registry as an Emergency Registered Nurse provider holding BSN-RN/PRESIDENT credentials at 137 KNOLL RD, Boonton, NJ, 07005, with a listed phone of (973) 394-0899. NPI 1700020393 was issued on 04/27/2009.

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 Emergency Registered Nurse providers operate outside Part D entirely.

Emergency Registered Nurse is a narrow specialty nationwide, with 4,350 enrolled providers across 54 states and an average of 710 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
