An EN (including a State VR agency acting as an EN) can elect to be paid under either the outcome payment system or the outcome-milestone payment system. The EN will elect a payment system at the time the EN enters into an agreement with us. (For State VR agencies, see § 411.365 .) The EN (or State VR agency) may periodically change its elected EN payment system as described in § 411.515 .
