The ten-digit identifier persists through changes such as name or address and carries no embedded specialty or location, so downstream teams need separate dated evidence for operational status.
Section 455.410 requires enrolled providers to be screened and brings ordering or referring physicians and other professionals into participating-provider enrollment, even when their role is not the billing event.
Under 42 CFR 482.12, the hospital's governing body determines eligible practitioner categories and appoints medical-staff members after considering the existing medical staff's recommendations.
CMS uses PECOS for Medicare enrollment and related maintenance; provider organizations still need separate evidence and authority for credentialing, privileging, and payer participation decisions.
42 CFR 455.436 requires Medicaid agencies to check defined providers and associated people against federal databases at specified points. Systems must preserve who, which source, when, and what followed.
42 CFR 482.22 permits a hospital to rely on certain distant-site credentialing and privileging decisions for telemedicine only through a defined written-agreement path. Reliance is governed, not automatic.
