Eris Zagar, APRN appears in the CMS NPPES registry as an Oncology Clinical Nurse Specialist provider holding APRN credentials at 1 HOSPITAL DR, Columbia, MO, 65212, with a listed phone of (573) 882-8445. NPI 1538115506 was issued on 05/25/2006.

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 Oncology Clinical Nurse Specialist providers operate outside Part D entirely.

Oncology Clinical Nurse Specialist is a narrow specialty nationwide, with 211 enrolled providers across 39 states and an average of 435 Part D claims per prescriber, so the context for interpreting these metrics differs meaningfully from a primary-care baseline.
