If the facilities are physically separate buildings from each other, whether on the same property or over multiple campuses, then they should be enrolled separately in NHSN. Each facility should have its own, unique NHSN OrgID. When a CCN is shared across multiple facilities, the CDC will aggregate the data from all applicable NHSN OrgIDs and will send to CMS under the single CCN for CMS reporting purposes. Each distinct facility should monitor HAIs and prevention efforts separately, for the purposes of accurate tracking and targeted infection control.
