Request Summary

• Service requested: [Chiropractic spinal manipulation] (Include adjunctive services only if part of this request and documented.)
• CPT/HCPCS codes: [CPT codes] (98940/98941/98942 as appropriate; add E/M or therapy codes only if requested.)
• Total visits and schedule: [Frequency] x [Duration] = [Total visits] (e.g., "2x/week for 4 weeks = 8 visits")
• Primary diagnosis: [Diagnosis name] (ICD-10: [Code])
• Additional diagnoses: [Diagnosis name(s) with ICD-10 code(s)] (Include only if documented.)
• Key objective findings: [1–3 documented objective findings]
• Key functional limitations: [1–3 specific functional deficits with metrics]
• Response to care to date: [Brief summary of symptom, function, and objective trends]

Clinical Background & Diagnoses

[Onset and mechanism] (Acute injury, exacerbation, or chronic course; onset date/duration; symptom trajectory.)

[Pertinent past history] (Prior episodes, surgeries, osteoporosis risk, neurological history, or other factors affecting treatment. If unknown, state explicitly.)

[Prior conservative care and results] (Medications, PT, HEP, imaging, injections, other providers, and outcomes. If unknown, state this and note attempts to obtain records.)

Diagnoses: (Primary first with ICD-10 codes.)

• [Primary diagnosis] (ICD-10: [Code])
• [Secondary diagnosis] (ICD-10: [Code]) (Include only if documented.)
• [Additional diagnoses] (ICD-10: [Code]) (Include only if documented.)

Subluxation documentation: [Subluxation level and region] (Include if required by payer. Document supporting evidence: imaging [modality, date, levels] OR physical exam findings demonstrating at least two of: pain/tenderness, asymmetry/misalignment, ROM abnormality, tissue/tone changes—one must be asymmetry or ROM.)

Objective Clinical Findings

(Include only clinician-measured findings from encounter notes, outcome tools, or imaging reports. If any payer-required objective element is missing, obtain the data before finalizing this letter.)

• Imaging: [Modality, date, region, levels, key findings] (Cite attachment number. Omit if not obtained.)
• Neurologic findings: [Strength/reflex/sensation with levels and laterality] (Omit if not relevant.)
• Orthopedic tests: [Named tests and side/level-specific results]
• Physical exam for subluxation: [Pain/tenderness], [Asymmetry/misalignment], [ROM abnormality], [Tissue/tone changes] (Document at least two; one must be asymmetry or ROM.)

Quantified measures and trend: (Include only measures actually recorded. Remove unused rows.)

Measure	Baseline (date/value)	Current (date/value)	Trend
Pain scale [location]	[Baseline date]: [value]/10	[Current date]: [value]/10	[Improved / Stable / Worsened]
ROM [region]	[Baseline date]: [degrees or % normal]	[Current date]: [degrees or % normal]	[Improved / Stable / Worsened]
[Neurologic or orthopedic measure]	[Baseline date]: [value]	[Current date]: [value]	[Improved / Stable / Worsened]

Functional Impairment

[Work status and role] (Describe specific task limitations and any restrictions or accommodations.)

• Sitting tolerance: [minutes/hours]
• Standing tolerance: [minutes/hours]
• Walking distance: [distance/time]
• Sleep disruption: [nights/week and cause]
• Lifting/carrying: [weight limit]
• ADLs impacted: [specific activities and limitations]

Validated outcome measure: [Tool name (ODI/NDI/PROMIS PF/RMDQ)] – Baseline: [date]: [value]; Current: [date]: [value]; Target: [value] by [timeframe]. (If not collected, obtain before submission or state not available with explanation.)

Planned reassessment interval: [Every X visits or by date]

Care Delivered to Date & Response

Initial treatment date: [Date]. Total visits completed: [Count]. Average frequency: [e.g., 2x/week].

• Interventions provided: [Spinal regions treated], [Manual therapy if applicable], [Therapeutic exercise/home program], [Patient education]
• Response to care: [Subjective symptom changes], [Objective measure changes], [Functional improvements with metrics]
• Measurement gaps: [Acknowledge any dates lacking progress measures. Do not claim improvement without recorded data.]

Requested Treatment Plan

• Visits requested: [Number] over [Duration] at [Frequency] (e.g., "2x/week for 4 weeks = 8 visits")
• Taper schedule: [Describe cadence reduction if applicable]
• SMART goals:
  • [Goal 1: Functional task + metric; target value; timeframe]
  • [Goal 2: Functional task + metric; target value; timeframe]
  • [Goal 3: Functional task + metric; target value; timeframe] (Optional.)
• Effectiveness tracking: [Objective measures and reassessment dates/visit counts]
• Re-evaluation checkpoint: [After X visits or by date]. If no measurable improvement: [Modify plan / refer / discharge]

Medical Necessity Rationale

• Condition severity: [Summarize objective evidence—pain levels, ROM loss, neurologic/orthopedic findings, imaging—with dates]
• Functional impairment: [Work and ADL impact with specific metrics]
• Appropriateness of chiropractic care: [Brief rationale aligned with diagnosis and payer policy; note contraindications addressed]
• Frequency/duration justification: [Why requested schedule is the minimum necessary; why fewer visits are insufficient]
• Alternatives tried/considered: [Conservative options attempted and outcomes]
• Expected improvement: [Measurable goals, timeframe, and tools to verify progress]
• Active/corrective vs maintenance: [Explicitly state this is active/corrective treatment with documented or expected functional gains, not maintenance care]

Response to Denial

(Include only for appeal submissions. Omit entire section for initial authorization requests.)

• Denial reason: "[Exact denial reason quoted]"
• Response: [Point-by-point rebuttal citing encounter dates, objective findings, outcome scores, and attachment numbers]
