Washington written opioid-treatment agreements, documented from the rule outward

Status: Washington evidence build reviewed through October 4, 2026. This library is for Washington patients, clinicians, attorneys, journalists, and researchers who need to distinguish what Washington itself requires from what an individual clinic, payer, or program adds.

Washington’s current legal baseline

Washington’s physician opioid-prescribing rules expressly require a written agreement for chronic-pain opioid therapy. WAC 246-919-910 makes the written agreement part of the chronic-pain treatment plan, and WAC 246-919-915 requires the physician to use a written agreement outlining the patient’s responsibilities.

Required agreement subject Current physician rule
Biological specimen testing The patient agrees to provide samples when requested by the physician.
Dose, frequency, lost prescriptions and early refills The agreement must address taking medication as prescribed and include a specific protocol for lost prescriptions and early refills.
Discontinuation The agreement must state reasons opioid therapy may be discontinued.
Single prescriber or clinic Chronic-pain opioid prescriptions must come from a single prescriber or single clinic, subject to the episodic-care rule.
Single pharmacy Chronic-pain opioid prescriptions are to be dispensed by a single pharmacy or pharmacy system whenever possible.
Alcohol / unauthorized substances The agreement must include the patient’s commitment not to abuse alcohol or use other medically unauthorized substances.
Violation consequence The agreement must state that violation may result in tapering or discontinuation of the prescription.
Medication security The patient must accept responsibility to safeguard medication and keep it secure.

Important 2025 patient-care safeguards

Washington amended the chronic-pain periodic-review and tapering rules effective March 21, 2025. WAC 246-919-920 now states that biological specimen testing should not be used punitively and that physicians should not dismiss patients from care based on a biological specimen result alone. WAC 246-919-950 now expressly says not all chronic-pain patients need tapering and requires patient-centered medical decision-making when tapering is considered.

Washington is actively revisiting the opioid rules in 2026

The Washington Medical Commission has an active rulemaking project covering WAC 246-919-850 through 246-919-985 and the parallel physician-assistant rules. The Commission describes the project as considering amendments to modernize language, clarify the rules, and align them with current practice. A September 28, 2026 opioid-prescribing workshop has already occurred, with additional opioid-rule and Chapter 246-919 workshops scheduled in October, November, and December 2026.

State and program records

Current Washington practice records

State rule versus clinic additions

Washington is stricter than many states because its rule itself mandates several agreement provisions. Even so, individual practices add materially broader conditions. Current Washington practice forms include fixed pill-count deadlines, one-hour specimen deadlines, zero-tolerance conduct provisions, cannabis prohibitions, extensive sedative prohibitions, no-show fees, work-participation requirements, fixed clinic dose ceilings, automatic discharge language, and specific pregnancy or sleep-apnea conditions. Those additional provisions must not be silently labeled statewide mandates.

If your Washington agreement is missing

Use the Washington Contract for Care submission guide. Blank copies are best. Preserve the complete agreement, revision date, clinic identity, testing/refill policies, and any addenda.

Evidence boundary: Washington requires a written agreement and specifies several mandatory subjects. That does not make every condition added by a clinic, insurer, workers’ compensation program, or other institution a universal Washington requirement.
