When is the Revalidation deadline?

The deadline for provider revalidation is rapidly approaching! Providers who did not begin the enrollment/revalidation process by January 1, 2017 put themselves at serious risk for delayed payments, as revalidation may take several weeks.

Providers are urged to begin the process now, through the Online Provider Enrollment (OPE) tool, in order to complete the process and receive their approval before the new enrollment and claims management system, Colorado interChange, launches on March 1, 2017.

Providers who have not enrolled into the Colorado interChange and received their approval by March 1, 2017, will not be able to submit claims or PARs, receive payments, or verify member eligibility (until they are approved).
