Each carrier submits enrollments to CMS as they are processed, and they receive an immediate response whether the client qualifies for the plan; if the client qualifies then the renewal commission rate is paid.  Once a month the carrier receives a report from CMS indicating the previous plan information for each enrollment previously submitted.  From that report the carrier will pay the additional commissions (True-Up) for the Initial and Unlike Plan Change enrollments.  The additional (True-Up) commissions are typically paid within 4-6 weeks of the first payment depending on the payment schedule of the carrier.
