When a decision for an assessment has been made, an organization may want to complete the assessment, to indicate that the determination is final and the decision can be used in further processing, such as making benefit payments. Determination-based assessments can be marked as complete in Decision Assist to facilitate this. At least one decision must exist in order to mark a determination as complete. Completed determination-based assessments cannot be updated. However, change of circumstance processing allows new determinations to be made over time for the same determination-based assessment.
