Purpose of Request

[Initial prior authorization / Re-authorization / Appeal — specify level if appeal]

• Modality: [Music therapy / Art therapy / Dance-movement therapy / Animal-assisted therapy / Equine-assisted services / Horticultural therapy]

• Total requested visits/units: [Number]

This request meets medical necessity criteria: services address a diagnosed condition with associated functional impairment; require a qualified, skilled professional; are time-limited with measurable goals; are expected to improve function/symptoms or prevent deterioration with objective monitoring; and are delivered in the least restrictive, safe, and appropriate setting coordinated with the overall plan of care.

• [Comorbid diagnosis] [ICD-10 code]

Symptom Burden and Severity

[Clinical narrative describing onset, course, current severity, and relevant symptom clusters] (Distinguish patient-reported from clinician-observed findings)

• [Standardized measure name, date]: [Score] ([Patient-reported / Clinician-rated])
• [Additional measure name, date]: [Score] ([Patient-reported / Clinician-rated])

Functional Impairment

• ADLs/IADLs: [Impairments with concrete examples and baseline metrics]
• Work/School: [Attendance, performance; baseline metrics such as missed days/week]
• Sleep/Self-care: [Duration, quality, hygiene, nutrition with measurable indicators]
• Social participation: [Isolation, conflict, avoidance with participation metrics]
• Emotional/behavioral regulation: [Episode frequency, triggers, safety concerns]
• Physical function: [Mobility, balance, fatigue, pain scores] (Include if relevant to modality)
• Utilization markers: [ED visits, hospitalizations, crisis contacts with dates and counts]

Risk Status

[Current risk level and mitigation plan] (Include only if risk affects authorization or setting selection)

Prior and Current Treatments

• [Treatment type] — [Dates]; Response: [Response / Partial / Nonresponse]; [Reason stopped or ongoing]
• [Treatment type] — [Dates]; Response: [Response / Partial / Nonresponse]; [Reason stopped or ongoing]
• Current active treatments: [Psychotherapy modality and frequency], [Medication management], [Rehabilitation therapies], [Case management] (Clarify that the requested experiential therapy is adjunctive and coordinated with—not replacing—core treatments)
• Barriers to sufficient response with current plan: [Persistent symptoms despite adequate trials / Plateau / Engagement limitations with verbal therapies / Sensory-motor integration barriers / Trauma-related avoidance / Cognitive deficits] (Base on documented observations and measured lack of improvement)

Medical Necessity Rationale

Clinical Indication for the Requested Modality

[Explanation of why this modality is indicated for this patient] (Link modality mechanisms—nonverbal emotional processing, sensorimotor regulation, graded exposure, distress tolerance, social communication practice, engagement support—to patient's documented problems and functional goals)

Need for Skilled Professional Services

• Assessment, treatment planning, and goal alignment with overall plan of care
• Graded task design and titration; adapting interventions based on response and safety cues
• Monitoring and mitigating risk: [Dissociation / Panic / Behavioral dysregulation / Falls / Animal-participant safety] (Include risks relevant to modality)
• Objective progress tracking and documentation with standardized tools
• Interdisciplinary communication and care coordination

Alternatives Considered

• [Alternative treatment] — [Why insufficient or less appropriate at this time]
• [Alternative treatment] — [Why insufficient or less appropriate at this time]

Evidence Base

[Brief summary of relevant evidence for the modality in similar conditions/populations] (Include only if helpful for authorization; acknowledge mixed evidence where appropriate; emphasize individualized monitoring and defined endpoints)

Proposed Treatment Plan

Provider Qualifications

• Rendering clinician: [Name, degree, licensure], [Modality-specific credential: MT-BC / ATR-BC / R-DMT / HTR / PATH Intl. CTRI / Other], [Population-specific training]
• Team composition: [Roles and supervision structure] (Include for team-based modalities such as equine-assisted or animal-assisted services)

Treatment Structure

• Format and location: [Individual / Group], [Clinic / Farm / Community site]
• Safety model: [Screening protocols, infection control, animal welfare standards, fall prevention, emergency procedures] (Include elements relevant to modality)
• Key intervention components: [Brief description of planned techniques using clear, non-proprietary terms]

Frequency and Duration

• [Number] sessions/week; [Number] minutes/session; planned episode: [Number] weeks
• Re-evaluation at weeks [Number] and [Number]; total requested visits: [Number]
• [Justification for higher-than-typical intensity] (Include only if requesting above-standard frequency)

Measurable Goals

• [Goal tied to symptom measure]: [Reduce/Improve] [measure name] from [baseline] to [target] by week [number]
• [Goal tied to functional metric]: [Increase/Decrease] [attendance/participation/behavior frequency] from [baseline] to [target] by week [number]
• [Goal tied to behavioral or physical function]: [Tolerate/Complete/Demonstrate] [specific task] in [number] of [number] trials by week [number]

Outcome Measurement Plan

• Tools: [Standardized scales], [Functional checklists], [Attendance tracking], [Utilization markers]
• Measurement frequency: Baseline, every [number] weeks, discharge
• Response criteria: [Quantified improvement thresholds tied to goals]
• Discontinuation criteria: [Plateau by week number / Adverse events / Goal attainment] — triggers step-down, modification, or discharge

Progress to Date

(Include this section only for re-authorization requests or if treatment has begun)

• Treatment start date: [Date]; Sessions completed: [Number]; Attendance: [Percentage]
• Outcome measures: [Measure name]: [Baseline score] → [Current score]; [Functional marker]: [Baseline] → [Current]
• Goal status: Goal 1: [Met / Partial / Not met]; Goal 2: [Met / Partial / Not met]; Goal 3: [Met / Partial / Not met]
• Plan modifications: [Adjustments made and clinical reasoning]
• Continued medical necessity: Skilled intervention remains required because [progress occurring but goals not yet met / risk of deterioration without skilled services / maximum improvement not attained]

Care Coordination

(Include when multiple providers are involved)

• Providers and roles: [Names and credentials — therapist, prescriber, primary care, care manager, others]
• Communication plan: [Interval], [Format], [Recipients]
• Safety/crisis plan: [High-level summary] (Include for behavioral health cases; omit psychotherapy details)
