ReferenceAbout Medicare Enrollment IDs

A Medicare Enrollment ID (ENRLMT_ID) is a 15-character public identifier assigned by the CMS Provider Enrollment, Chain and Ownership System (PECOS) when a provider, supplier, or organisation enrols in Medicare. Each row reflects one enrolment record: a single NPI can hold multiple enrolments across provider types, states, or supplier categories. Data here is mirrored from the quarterly public PECOS enrolment file published on data.cms.gov.
