The physician assistant, having recognized the progression of a patient from the acute nonoperative or acute perioperative phase to the subacute phase shall develop an opioid treatment plan.

(1) If tapering has not begun prior to the six- to twelve-week subacute phase, the physician assistant shall reevaluate the patient. Based on effect on function or pain control, the physician assistant shall consider whether opioids will be continued, tapered, or discontinued.

(2) If the physician assistant prescribes opioids for effective pain control, such prescription must not be in a greater quantity than needed for the expected duration of pain that is severe enough to require opioids. During the subacute phase the physician assistant shall not prescribe beyond a fourteen-day supply of opioids without clinical documentation to justify the need for such a quantity.

(3) If a prescription results in the patient receiving a combination of opioids with a sedative medication listed in WAC 246-918-920, such prescribing must be in accordance with WAC 246-918-920.

(4) If the physician assistant elects to treat a patient with opioids beyond the six- to twelve-week subacute phase, the physician assistant shall document in the patient record that the patient is transitioning from subacute pain to chronic pain. Rules governing the treatment of chronic pain, WAC 246-918-855 through 246-918-905, shall apply.
