Evidence status: CURRENT BINDING AMENDMENTS EFFECTIVE MARCH 21, 2025. Washington amended key chronic-pain rules in 2025 to make testing and tapering language more explicitly patient-centered.
Biological testing cannot be treated as a standalone punishment mechanism
WAC 246-919-920 now states that biological specimen testing should not be used in a punitive manner. It should be interpreted with other clinical information to inform and improve patient care. The rule also states that physicians should not dismiss patients from care based on a biological specimen test result alone.
Agreement violations require a documented response
If a patient violates the written agreement, the physician must document both the violation and the physician’s response, together with the rationale for any change in the treatment plan.
Tapering is not automatic
WAC 246-919-950 now begins by stating that not all chronic-pain patients need their opioid prescriptions tapered. When tapering or referral for substance-use-disorder evaluation is considered, the rule directs the physician to rely on medical decision-making and patient-centered treatment.
When tapering must be considered
The current rule identifies circumstances including a patient request, deterioration in function or pain, noncompliance with the written agreement, indications for other treatment modalities, evidence of misuse or diversion, severe adverse events or overdose, unauthorized dose escalation, or dose escalation without improvement in pain or function.
Why this matters to Contract for Care
Washington still mandates the written agreement, but its current rules reject a simplistic reading in which every test result or contract problem automatically means dismissal. Clinic agreements that impose automatic consequences should therefore be classified as clinic rules unless the binding regulation itself requires that particular consequence.
Physician-assistant rule
The parallel physician-assistant periodic-review rule, WAC 246-918-870, contains the same nonpunitive-testing and no-dismissal-on-test-result-alone language.

Evidence boundary: These safeguards do not erase Washington’s written-agreement requirement. They constrain how parts of the monitoring and treatment-response system are described and applied.
