Date of Request: [Date]

Request Type: [Initial / Resubmission / Appeal / Peer-to-peer requested]

Urgency: [Routine / Expedited] (If expedited, justify in the Medical Necessity Synopsis with specific risk of harm from delay.)

Patient: [Full name], [DOB], [MRN]

Insurance: [Plan name], [Member ID], [Group number]

Facility/Site of Service: [Facility name and address or NPI]

Ordering Clinician: [Name, credentials, specialty]

NPI: [Ordering clinician NPI]

Contact for Peer-to-Peer: [Phone], [Fax], [Best call times]

Requested Study

Modality: [MRI / CT / Ultrasound]

Protocol: [Anatomic region], [Laterality], [With contrast / Without contrast / With and without contrast], [Contrast type if known]

CPT Code(s): [CPT codes]

ICD-10 Code(s): [Primary diagnosis and symptom codes]

Clinical Question: [One sentence stating the target diagnosis to confirm or exclude and the clinical rationale] (Be specific about pathology and context; avoid generic statements.)

Medical Necessity Synopsis

[4–8 sentence narrative synthesizing the case for approval] (Include: chief complaint with onset, duration, and trajectory; key objective findings or explicit failure of conservative therapy with functional impairment; relevant prior testing and why inadequate; why this modality is needed now; and how results will change management. Embed specific dates, durations, and exam findings. Write as a single paragraph suitable for standalone review.)

Clinical History and Examination

Chief Complaint: [Primary symptom(s), location, laterality, distribution]

Timeline: [Onset date], [Course: improving / stable / worsening / recurrent], [Severity: pain score or equivalent], [Functional impact], [Night pain or episode frequency]

Relevant Medical History: [Problem-focused history affecting appropriateness, urgency, safety, or protocol] (Include prior surgery to region, malignancy history, infection risks, CKD, pregnancy status, implanted devices, or other factors influencing modality/contrast choice.)

Physical Examination: [Objective findings pertinent to region] (For spine/neurologic: motor strength by myotome, reflexes, dermatomal sensation, gait, straight-leg raise, bowel/bladder findings. For MSK: ROM, swelling, instability tests, tenderness. For abdominal/pelvic: localized tenderness, guarding, palpable mass. If exam not performed, state reason and reference other objective data with source and date.)

Pertinent Negatives: [Negatives relevant to approval criteria] (Document explicitly, e.g., absence of fever for infection concern, absence of bowel/bladder dysfunction for cauda equina.)

Conservative Management and Prior Evaluation

Non-Pharmacologic Therapy: [Physical therapy: supervised vs home, dates, visits, adherence], [Activity modification], [Bracing/orthotics], [Other therapies], [Response: improved / no change / worsened]

Pharmacologic Therapy: [NSAIDs/acetaminophen: duration and response], [Neuropathic agents], [Muscle relaxants], [Oral steroids], [Contraindications or intolerance] (Include start/stop dates and outcomes.)

Procedures/Specialist Care: [Injections], [Prior surgery], [Specialist evaluations], [ED visits] (Include dates and degree/duration of relief.)

Prior Imaging/Testing: [Modality, body part, date, key result] (State why insufficient: wrong region, too early, non-diagnostic, or does not address current question. If repeating imaging, specify clinical change prompting repeat.)

Summary Statement: [Explicit statement of persistence despite therapy] (Example: "Persistent symptoms despite [X weeks] of [specific therapy], resulting in [functional limitation].") (Avoid generic phrases without specifics.)

Red Flags

  • [ ] Suspected malignancy (history of cancer, unexplained weight loss): [Details with dates if present]
  • [ ] Suspected infection (fever, immunosuppression, IVDU, recent bacteremia): [Details if present]
  • [ ] Significant trauma or fracture risk (trauma, osteoporosis, chronic steroids): [Details if present]
  • [ ] Progressive or severe neurologic deficit: [Distribution, strength/reflex changes, dates if present]
  • [ ] Suspected cauda equina (urinary retention, saddle anesthesia, severe bilateral symptoms): [Details if present]
  • [ ] Severe unremitting night pain or pain at rest: [Details if present]
  • [ ] Other urgent/emergent indication: [Specify]

(If expedited, state why delay risks harm and what time-sensitive decision depends on imaging.)

Why This Modality

[Rationale for requested modality and protocol] (Justify based on diagnostic performance: MRI for soft tissue/neural detail and marrow/infection/neoplasm; CT for fracture/bony detail or acute hemorrhage; Ultrasound for vascular/soft tissue and dynamic assessment. State why alternatives are inadequate and why timing is appropriate now.)

How Results Will Change Management

  • If [positive finding] → [Specific action: surgical referral, procedural planning, targeted therapy, oncologic workup]
  • If [negative/benign finding] → [Alternative plan: continue conservative management, avoid invasive intervention, surveillance]
  • If [concerning incidental finding] → [Expedited workup or referral]

Contrast and Safety Considerations

(Omit this section entirely for non-contrast ultrasound or when clearly not applicable.)

Contrast Justification: [Clinical reason contrast is needed; why non-contrast is insufficient] (Mark "Not applicable" for non-contrast studies.)

Contrast Risk Screening: [Prior contrast reaction and severity], [Premedication plan if applicable], [Most recent creatinine/eGFR with date], [Pregnancy/lactation considerations]

MRI Safety: [Implants/devices and MRI-conditional status], [Claustrophobia/sedation needs], [Body habitus limitations] (If unknown, document "unknown—will confirm prior to scheduling.")
