Executive Summary

[Reviewer-ready synopsis in 3–6 sentences: chief problem and duration; working diagnosis or clinical concern; key positive findings and relevant negatives; prior management and studies; exact test requested; how results will change management] (Use precise dates. Ensure consistency with all sections below.)

Requested Service

  • Imaging: [Modality, body region with laterality, with/without contrast, sedation if needed, protocol details if relevant] – CPT/HCPCS: [Code(s)] (Include only for imaging requests.)
  • Laboratory/Genetic Test: [Test name as performed by lab, methodology if relevant, specimen type, performing lab name] – CPT/HCPCS: [Code(s)], Payer test ID: [If required] (Include only for lab/genetic requests.)

Diagnoses and Indications

  • Primary: [Diagnosis or indication] – ICD-10-CM: [Code]
  • Secondary: [Relevant diagnoses/comorbidities affecting necessity] – ICD-10-CM: [Code(s)] (Include only if they materially support necessity.)
  • Differential: [Diagnosis being ruled out] (Include only if directly supportive of request.)

Clinical Question

[Specific clinical question this test must answer] (One to three sentences. Must align with the requested service and diagnoses.)

Clinical Summary

  • Symptoms:
    • [Onset date and total duration]
    • [Progression, severity, and frequency]
    • [Red flags or urgent features] (Include only if present.)
    • [Functional impact] (Include only if relevant to criteria.)
  • Relevant History:
    • [Prior related diagnoses and pertinent comorbidities]
    • [Relevant surgical/procedural history]
    • [Medications affecting the test or safety]
    • [Family history/ancestry] (Include for genetic indications.)

    • [Pertinent positive findings]
    • [Key negative findings relevant to approval criteria]
    • [Focused neuro/MSK/phenotypic findings as applicable]
  • Prior Testing and Results:
    • [MM/DD/YYYY] – [Test/Study] – [Key result and interpretation]
    • [MM/DD/YYYY] – [Test/Study] – [Key result and interpretation]
    • [External records requested MM/DD/YYYY; pending receipt] (Include if applicable.)

Conservative Management

(Include for outpatient advanced imaging, especially MSK/spine. Provide dates, durations, and responses for each intervention.)

  • Physical therapy: [Start–End dates], [# sessions], Response: [Response]
  • Home exercise/activity modification/bracing: [Start–Reassessment dates], Response: [Response]
  • Medications: [Agent/class], [Duration with dates], Response: [Response or adverse effects]
  • Injections/procedures: [Type], [MM/DD/YYYY], Response: [Response]
  • Conservative therapy not performed: [Reason: contraindicated / red flags present / acute trauma / not required per policy] (Include only if conservative management was not attempted; must justify.)

Medical Necessity Rationale

  • [Why the test is needed now: failure of initial management, progression, new deficit, staging, treatment selection]
  • [Why lower-intensity alternatives are insufficient: prior nondiagnostic studies, clinical limitations]
  • [Why the requested modality best addresses the clinical question for this patient]
  • [Contrast justification and safety: renal function, allergy, pregnancy] (Include only if contrast requested.)
  • [Guideline or payer policy alignment] (Include if known.)
  • [Risk of delayed or denied testing] (Include if clinically significant.)

Expected Impact on Management

(Required. Map likely test outcomes to specific next steps. Avoid generic statements.)

  • If [result A], then [management/action A].
  • If [result B], then [management/action B].
  • If [negative/incidental finding], then [contingency plan].

Safety and Special Requirements

(Include only elements relevant to the requested test.)

  • Pregnancy status: [Status and precautions]
  • Renal function: eGFR [Value] on [MM/DD/YYYY] (Required if IV contrast planned.)
  • Contrast allergy: [History and premedication plan]
  • MRI safety: [Implants/devices, claustrophobia, sedation plan]
  • Genetic testing requirements: [Counseling/consent status, known familial variant, prior tumor testing]
  • Other safety considerations: [Anticoagulation, isolation, pediatric needs]
  • Items pending: [Elements to obtain prior to scheduling]
