  • The limit on the quantity or dose of a requested drug
  • A requirement that a member try another drug before CHRISTUS Health Plan will pay for the requested drug
  • A decision on whether the member has or has not satisfied a prior authorization or other utilization management requirement

Part D Coverage Determination & Exception Decisions

For requests for benefits that do not involve exceptions, the Plan will provide notice of its decision within 24 hours after receiving an expedited request or 72 hours after receiving a standard request.

For requests for benefits that involve exceptions, the adjudication timeframes do not begin until the member’s prescriber submits his or her supporting statement to the Plan for review.

For payment requests, including payment requests that involve exceptions, CHRISTUS Health Plan Generation will provide written notice of its decision (and make payment when appropriate) within 14 calendar days after receiving a request.

If CHRISTUS Health Plan Generation coverage determination is unfavorable, the decision will contain the information needed to file a request for appeal/ redetermination with the Plan.
