Summary & Overview
HCPCS M1351: Suicide Safety Plan Initiation and Follow-up
HCPCS Level II code M1351 designates initiation, review, or update of a suicide safety plan in collaboration with the patient and clinician, with a required review within 120 days of initiation. This code captures a focused behavioral health intervention intended to reduce immediate suicide risk and document ongoing safety planning activity tied to a clinical encounter. Nationally, accurate use of this code supports coordination of care across outpatient behavioral health, primary care behavioral health integration, and emergency services, and informs quality measurement and resource allocation for suicide prevention efforts. Key payers in scope include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarks and coding guidance context, payer coverage considerations, clinical context for when the code applies, and operational notes on documentation timing and encounter alignment. The publication also outlines policy-relevant points that affect billing and quality tracking for suicide prevention services, and highlights practical implications for clinical documentation, care coordination, and follow-up scheduling. Data not available in the input is noted where specific payer policy details, associated taxonomies, and ICD-10 linkage would typically be listed.
Billing Code Overview
HCPCS Level II code M1351 documents that a suicide safety plan was initiated, reviewed, or updated in collaboration with the patient and their clinician either concurrent with or within 24 hours of a clinical encounter, and that the plan was reviewed and updated within 120 days after initiation. The service type is behavioral health safety planning and follow-up case management focused on suicide risk mitigation. The typical site of service includes outpatient behavioral health clinics, primary care behavioral health integrations, emergency departments, and other clinical settings where suicide risk assessment and safety planning occur.
Clinical & Coding Specifications
Clinical Context
A 32-year-old patient presents to an outpatient behavioral health clinic for follow-up after initial psychiatric intake that identified active suicidal ideation with intent. The patient is seen by a licensed clinical social worker or psychiatrist for a scheduled or urgent visit. During the encounter the clinician conducts a structured safety assessment, collaborates with the patient to create or update a written suicide safety plan, and reviews crisis contacts, means restriction, warning signs, coping strategies, and follow-up care. The safety plan is reviewed with the patient during the visit and documented in the chart; the plan is subsequently reviewed again within 24 hours (by phone or secure message) or updated jointly within 120 days if clinical change warrants. Typical workflow steps: intake or triage identifies risk → clinician completes risk assessment and engages patient in collaborative safety planning → plan is documented and provided to the patient (printed or electronic) → clinician arranges follow-up, notifies supports as appropriate, and documents any 24-hour or 120-day review/update.
