Re: [Patient Full Name] (DOB: [MM/DD/YYYY]); Member ID: [Member ID]; [Claim or Prior Authorization Reference]; Request: Permanent [dorsal column SCS / dorsal root ganglion (DRG) stimulation] implantation; Planned site of service: [Ambulatory Surgery Center / Hospital Outpatient / Inpatient]

Dear [Medical Director / Utilization Management Reviewer],

[Executive Summary] (State the conclusion upfront in one concise paragraph: Permanent SCS is medically necessary to treat the primary pain diagnosis and chronicity. Establish that SCS is requested as a late-resort therapy after appropriate conservative treatments failed, were not durable, or are contraindicated. Affirm that multidisciplinary and psychological screening is completed with no contraindications, or explicitly state if pending. Include trial dates and key success metrics: percent pain relief, functional improvement, and medication changes. Conclude by stating that permanent implantation is requested to maintain these gains toward defined functional goals.)

Clinical Indication and Diagnostic Basis

Working diagnosis: [Primary diagnosis driving SCS request] (Use specific neuropathic descriptors when accurate, e.g., radicular pain, allodynia, hyperalgesia.)

Target pain: [Anatomic location(s)], [laterality], [dermatomal or distribution pattern]

Duration and course: [Onset date or approximate period], [course: persistent / progressive / fluctuating], [impact on ADLs, work, sleep]

Pertinent objective findings: [Neurologic deficits], [allodynia or paresthesia on exam], [gait or functional findings] (Include only clinician-observed findings.)

Relevant imaging and diagnostic studies: [Study type and date] — [concise relevant findings] (Reference attached reports. If results exist but are not yet available, state: "Report dated [date] referenced; copy pending." Do not infer unstated findings.)

Prior procedures and surgical history: [Procedure(s) and date(s)], [outcomes and durability], [complications] (If a surgical opinion is required for coverage but not yet obtained, state: "Surgical evaluation pending; permanent implantation request should be deferred until completed.")

Conservative Care Summary

(Provide a structured, dated account of modalities tried. Distinguish chart-verified dates from patient-reported dates. Tie contraindications to specific clinical rationale.)

• Physical therapy / Exercise-based rehabilitation:
  • Dates and duration: [Start–End; frequency; total visits] [Chart-verified / Patient-reported]
  • Program: [Spine stabilization / McKenzie / graded activity / HEP]
  • Adherence: [Good / Variable / Limited] [Reason if limited]
  • Response: [Baseline vs post-PT pain or function scores], [percent change]
  • Reason stopped: [Plateau / Worsened pain / Not durable / Contraindicated due to [clinical reason]]
• Medications: (List by class with dose, duration, response, and reason discontinued)
  • NSAIDs: [Agent(s), dose, duration, response, adverse effects, reason stopped]
  • Neuropathic agents: [Gabapentinoids / SNRIs / TCAs: agent, dose, duration, response, reason stopped]
  • Opioids: [Agent(s), MME/day baseline and current], [duration], [taper attempts], [adverse effects]
  • Other analgesics: [Muscle relaxants, topicals, others as applicable]
  • Contraindications: [e.g., CKD precluding NSAIDs; QTc prolongation with TCA; SUD risk] with date and source
• Interventional procedures:
  • [Procedure type]: [Date(s)], [levels/side], [percent pain relief and duration], [reason further intervention not indicated]
• Behavioral pain therapy:
  • Type: [CBT / ACT / Biofeedback / Pain psychology]
  • Dates and duration: [Sessions and timeframe]
  • Engagement: [Good / Limited], [barriers if any]
  • Response: [Validated measure or functional change]
• Other modalities: [TENS / acupuncture / chiropractic / bracing]: [Dates], [response], [reason discontinued]

Surgical evaluation: [Consultant name, specialty, date, conclusion] (Include only if corrective surgery was considered. State whether further surgery is not indicated and why, or if evaluation is pending.)

Multidisciplinary and Psychological Screening

Evaluator: [Discipline], [Name], [Credentials], [Date]

Assessment methods: [Clinical interview / MMPI-2-RF / PHQ-9 / GAD-7 / ORT / other validated tools]

Key findings: [Patient understanding of therapy and maintenance burden], [mood and anxiety screening results with management plan if indicated], [substance use disorder screening status], [realism of expectations], [coping skills and adherence capacity]

Conclusion: [No psychological contraindications identified / Contraindications identified with mitigation plan] (State "cleared" only if formal evaluation occurred. If only screening questionnaires were completed, document exactly that. If screening is incomplete, state: "Permanent implantation not being requested until psychological screening is completed.")

Patient education documented: [Role of trial vs permanent implant], [expected partial pain relief with emphasis on function], [risks and complications], [long-term device maintenance and follow-up requirements]. Patient preferences align with treatment goals and patient can participate in required follow-up.

SCS Trial Summary and Outcomes

Trial procedure: [Dates and total duration], [Lead approach: percutaneous / surgical], [Number of leads and contacts], [Anatomic lead levels], [Coverage approach: paresthesia-based / paresthesia-free], [Setting], [Complications: none / describe] (Reference attached operative note.)

Outcomes — baseline vs trial:

• Pain intensity ([NRS / VAS] 0–10): Baseline [X] → End-of-trial [X]; [X]% improvement in target pain
• Functional outcome ([ODI / RMDQ / patient-specific activity]): Baseline [score or tolerance] → End-of-trial [score or tolerance]; [Net change]
• Analgesic use: Opioid [MME/day baseline → end-of-trial]; Adjuvants [baseline → end-of-trial]; [Net change]
• Tolerability: [Stimulation comfort], [sleep quality], [activity tolerance], [rehab participation]

Success determination: [Meets standard threshold: ≥50% reduction in target pain / Alternative pathway: ≥50% reduction in analgesic use with documented functional improvement] (If pain reduction is below 50% but function or medication use improved substantially, clearly document the rationale. If baseline metrics were not collected pre-trial, state this explicitly and use best-available alternative measures.)

Functional Goals for Permanent Implantation

(List 3–5 measurable, time-bound goals aligned with trial improvements. Specify the metric and measurement method.)

• [Goal 1: e.g., Increase walking tolerance to [distance or duration] within [4–12 weeks], measured by [patient log / 6MWT / clinic assessment]]
• [Goal 2: e.g., Improve standing tolerance to [minutes] for household tasks within [timeframe], measured by [patient report / ADL checklist]]
• [Goal 3: e.g., Reduce opioid use to [target MME or percent reduction] as clinically appropriate within [timeframe], monitored via PDMP]
• [Goal 4: e.g., Improve sleep quality to [target nights/week without pain awakening], measured by [sleep diary]]
• [Goal 5: e.g., Resume participation in [PT / HEP] [frequency] for [duration], measured by therapist documentation]

Follow-Up Plan

• Permanent implant approach: [Percutaneous cylindrical leads / Paddle leads]; Target: [Dorsal column / DRG]; Levels: [Planned levels]; Decision [finalized / pending]
• Perioperative management: [Anticoagulation plan], [infection prevention measures]
• Post-implant care: Wound checks at [7–14 days]; Programming at [weeks 1–2, weeks 4–6, and as needed]; Activity precautions for [X weeks]; Coordination with [PT / PM&R] for graded conditioning
• Medication management: [Conditional taper strategy if clinically appropriate] (No guarantee of opioid discontinuation; close follow-up planned.)
• Follow-up schedule: [Visit cadence over first 3–6 months], [contact for device issues]
