Executive Summary

(Keep this section concise and scannable, approximately 6–12 lines. Present the diagnosis → impairment → functional limitation → skilled need → specific request → expected outcomes chain.)

• Clinical context: [Primary diagnosis with onset/trigger and ICD-10 code]
• Functional impact: [What the patient cannot do safely or independently]
• Medical necessity: [Why skilled therapy and/or specific equipment is required; why unskilled care or standard devices are insufficient]
• Explicit request: [Therapy discipline(s) with frequency/duration/total visits] and/or [Equipment item(s) with essential features]
• Top measurable outcomes: [Outcome #1 with target and timeframe]; [Outcome #2]; [Outcome #3]; [Outcome #4 if applicable]
• Clinical urgency: [Fall risk / Aspiration risk / Pressure injury risk / Contracture risk / Time-sensitive window] (Include only if documented clinical urgency exists)

Appeal Details

(Include this section only for appeals.)

• Denial reference: [Payer denial reference number and date]
• Denial reason quoted: [Payer-stated rationale]
• Point-by-point rebuttal: [Evidence-based response referencing attached evaluations, outcome measures, and guidelines]

Clinical Diagnoses and Relevant History

(Include only conditions that materially affect function, safety, therapy complexity, or equipment selection.)

• Primary diagnosis(es): [Diagnosis with ICD-10 code]
• Relevant secondary conditions: [Diagnoses with ICD-10 codes] (Include only if they affect function or intervention/equipment selection)
• Onset/exacerbation/surgery/injury date: [Date]
• Baseline vs. current function: [Prior level of function compared to current status in ADLs, mobility, communication, swallow, or work/school tasks]
• Relevant medications/procedures/precautions: [List] (Include only if they directly affect therapy or equipment)
• Environment and supports: [Home layout, caregiver availability, school or work demands] (Include only if relevant to the request)

Functional Status and Impairments

(Present objective findings first, then task-level function. Use the most persuasive measures relevant to the requested services or equipment. If a test was not feasible, state why and the plan to obtain baseline measures.)

Objective Impairments

• Strength/ROM/tone: [Key measurements by region and laterality]
• Balance/fall metrics: [Test name and result, assistive device used]
• Gait/mobility: [Speed, distance, tolerance, transfer status, device or bracing used]
• Fine motor/coordination: [Standardized or observational findings]
• Cognition/communication: [Screening or assessment results pertinent to therapy or equipment training]
• Swallow/nutrition: [Clinical or instrumental findings relevant to safety]
• Skin/orthopedic/other: [Pressure risk areas, contracture risk, wounds, precautions]

Functional Limitations and Safety Risks

• ADLs/IADLs: [Tasks the patient cannot do or performs unsafely; level of assistance required]
• Mobility/transfers: [Bed, chair, toilet, car transfers; gait; stairs; assistance level and devices]
• Communication/participation: [Expressive, receptive, or participation barriers impacting daily life]
• Swallow/feeding: [Diet level, aspiration indicators, supervision needs]
• Safety risks: [Falls / Aspiration / Skin breakdown / Contractures / Caregiver injury risk with brief context]
• Participation restrictions: [School access, work duties, community integration] (Include only if directly tied to limitations above)

Prior Treatments and Response

(Include for continued care requests, appeals, and equipment requests where prior equipment history is relevant. If records are unavailable, note this and attribute information to patient or caregiver report.)

• Therapy to date: [Dates, frequency, setting, adherence] with measurable response: [Key outcome changes]
• Home program: [Exercises or strategies attempted, adherence, barriers]
• Prior equipment/AT: [Item(s), fit or performance issues, safety concerns, why no longer meets needs]

Medical Necessity Rationale for Skilled Therapy

(Include when requesting therapy services. Explicitly state why skilled intervention is required and why unskilled care alone is insufficient.)

• Skilled needs: [Ongoing assessment, intervention progression, safety management due to medical complexity, specialized techniques requiring clinical judgment]
• Caregiver training: [Training that requires therapist assessment, cueing calibration, and verification of carryover]
• Maintenance/prevention rationale: [Expected decline without skilled care and why periodic skilled intervention remains necessary] (Include only if goal includes maintenance or prevention of decline)
• Frequency/duration justification: [Severity and complexity, risk level, dose needed for measurable change, caregiver training needs, time-limited windows]

Proposed Therapy Plan

(Organize by discipline requested. Include SMART goals that are primarily functional. Repeat this block for each requested discipline.)

[Discipline: PT / OT / SLP]

• Setting: [Outpatient / Home health / School / Inpatient rehab / Telehealth]
• Evaluation date: [Completed eval date / Planned eval date if requesting evaluation authorization]
• Frequency and duration: [Sessions per week] for [Total weeks]; Total visits: [Number]
• Treatment focus: [Intervention categories with patient-specific targets]
• Goals (SMART):
  • [Goal 1: Baseline → Target, Measurement method, Timeframe]
  • [Goal 2: Baseline → Target, Measurement method, Timeframe]
  • [Goal 3: Baseline → Target, Measurement method, Timeframe]
• Reassessment interval: [Timeframe and tools]
• Discharge/transition criteria: [Objective criteria for discharge or transition to lower level of care]

Equipment Request

(Include only when requesting equipment or assistive technology, or when equipment is integral to the therapy plan. Repeat this item block for each requested device.)

Item #[Number]: [Device description and model]

• HCPCS code: [Code]
• Quantity: [Number]
• Accessories/options: [List each separately if essential or separately billable]
• Face-to-face encounter date: [Date]
• Device evaluation/trial: [Dates and clinicians involved]
• Medical necessity rationale: [Functional problem the device solves; why standard or less costly alternatives are insufficient; why each requested feature is required tied to impairment, safety, or fit requirement]
• Prior equipment/trial results: [Findings and limitations leading to current selection]
• Training plan: [Patient and caregiver training outline and verification of safe use]
• Anticipated duration of need: [Timeframe]
• Expected measurable benefits: [Outcomes tied to function, safety, or participation]

Expected Outcomes and Prognosis
