If a drug is not covered, - you can ask for an exception
The decision about what drugs are prescribed is between you and your doctor. Some drugs your physician prescribes may not be covered by the Canada Post drug plan, but coverage may be provided for alternative drugs that provide a similar benefit. If the drug you’ve been prescribed is not covered, you can ask your doctor to prescribe a drug from the list of covered drugs. You can also take a prescribed drug that is not covered, but you will have to pay the full cost for it. However, if you have a contraindication or if you have tried a drug on the covered list and it did not work for your medical condition, you can apply to have your drug covered by the drug plan. You can do this by asking your doctor to complete the Request for Drug Exception form, which is found on page two of the list of covered drugs. You are responsible for any expenses incurred for completing the form.

Prior authorization
Some drugs need to have prior authorization from Great-West Life before a claim can be reimbursed. If the drug you searched for requires ‘prior authorization’, you must:
  1. Obtain a copy of the "Request for Information" form, which can be downloaded by visiting Great-West Life’s website and looking under Client Services/Group Benefits Plan Members/ Forms.
  2. Complete the form. Some information must be provided by your physician.
  3. Pay any administrative costs charged by your physician for completing the form. The plan does not cover these costs.
  4. Return the signed and completed form to Great-West Life at the address shown on the form before or along with your first claim for the drug.
  5. You will receive a letter from Great-West Life confirming whether the drug has been authorized or not.
  6. If the drug is authorized, you can go to your pharmacy to have your prescription filled or submit your claim for reimbursement.
