WCB Alberta C913: Opioid Treatment Agreement

This two-page agreement is signed by the prescribing physician and the worker when opioids are prescribed for non-malignant pain on a WCB-Alberta claim beyond the short term. By signing, the worker accepts 11 conditions, from a single prescriber and pharmacy to random urine drug screening, and agrees to take part in function-improving programs and cooperate with return-to-work efforts.

Who completes it

The worker reads and signs the 11 conditions, and the chosen physician, the designated opioid treatment provider, co-signs; both names, the place and the date are recorded.

Submitting and payment

How to submit it
Send the signed agreement to WCB-Alberta for the claim file; under WCB's opioid policy, the written agreement must be on file before long-term opioid therapy begins.

Good to know

  • The form is meant for opioids prescribed for non-malignant pain more than 12 weeks after injury, while WCB's 2023 policy treats pain lasting usually beyond four weeks as long-term therapy.
  • The worker agrees not to use over-the-counter opioids such as 222's and Tylenol No. 1, or alcohol and other mood-modifying drugs unless the physician agrees.
  • Lost or early-finished prescriptions are not replaced early; the worker waits for the next prescription, and breaking the conditions can end opioid prescribing.
  • Once long-term therapy starts, WCB policy requires a progress report within four weeks and every three months, covering dose, function, pain intensity and opioid-related harms.
