RE: Request for coverage of [requested item or service] for [patient name, DOB]

Request Type: [Prior Authorization / Exception Request / Appeal / Continuation-Renewal] [Reference numbers if applicable for appeal or continuation]

Dear [Utilization Management Reviewer or Medical Director]:

Request Summary

• Primary diagnosis: [Diagnosis name] [ICD-10 code if available]
• Key symptoms and functional impairment: [Symptom or impairment 1 in measurable terms]; [Symptom or impairment 2]; [Symptom or impairment 3] (Include only symptoms explicitly documented)
• Requested item or service: [Supplement / Medical food / Integrative therapy] - [Exact product or modality name]
• Proposed regimen: [Dose, frequency, duration or session plan]
• Why medically necessary now: [Patient-specific urgency and rationale]
• Expected outcomes: [Measurable targets linked to diagnosis and symptoms]

Clinical Problem Statement

[Primary diagnosis] with [relevant comorbidities affecting treatment selection or safety]. [Brief narrative linking diagnosis to clinical context.]

[Symptom burden and functional impairment with objective metrics such as validated scales, frequency counts, ADL limitations, work-school impact, weight trajectory, or other documented functional measures.]

[Pertinent clinical data including exam findings, lab results with dates and values, and nutritional assessment elements when applicable.] (Include only results explicitly available in the record. If key data is pending, state: "Lab ordered [date]; results pending. Coverage requested to avoid treatment delay because [clinical reason].")

Prior Treatment and Response

• [Intervention 1]: [Dose or intensity], [Dates-duration], [Response: benefit / partial / none], [Reason discontinued: adverse effects / ineffective / contraindicated / access barrier]
• [Intervention 2]: [Dose or intensity], [Dates-duration], [Response], [Reason]
• (Add additional interventions as documented)

(If new diagnosis with no prior treatment, state why conservative measures are inappropriate or insufficient.)

[Explanation of why standard alternatives are inadequate for this patient, citing clinical failure, contraindications, or patient-specific barriers such as swallowing limitations, malabsorption, intolerances, or adherence factors.]

Requested Intervention

• Category: [Supplement / Medical food / Integrative therapy]
• Product or service: [Brand or generic name, or modality] [Route if applicable]
• Quantity: [Units per month or total sessions], [Number of refills or authorization months]
• Start date and duration: [Start date] for [Authorization duration or range with reassessment milestone]
• ICD-10 code(s): [Diagnosis codes]
• CPT-HCPCS code(s): [Procedure codes] (Include only if known and required by payer)
• Dosing and administration: [Dose], [Frequency], [Route], [Timing], [Titration plan if any]
• For integrative therapies: [Session length], [Frequency], [Total sessions], [Reassessment point] (Include only if applicable)

Medical Necessity Rationale

[Clear linkage of diagnosis and pathophysiology or distinctive nutritional requirement to the requested intervention and expected clinical outcomes.]

[Why this option is required instead of lower-cost or standard alternatives, including patient-specific constraints, contraindications, drug-nutrient interactions, excipient allergies or intolerances, formulation requirements, or adherence considerations.] (If requesting a specific brand, justify distinguishing features necessary for this patient.)

This intervention is not experimental or investigational under current evidence. The requested duration and frequency are appropriate and not excessive. I am qualified to supervise this therapy.

[Brief evidence support citing 1-3 key references or guidelines, e.g., society guideline name and year, or pivotal trial author and year.]

Monitoring and Follow-Up Plan

• Clinical response tracking: [Symptom logs, validated scales, or frequency counts] assessed [interval]
• Objective monitoring: [Labs or measures] with [target values], [timing], and [safety parameters]
• Follow-up: [Next visit date or timeframe], monitored by [provider or team]
• Stop or modify criteria: [Thresholds for discontinuation or modification if inadequate response or adverse effects]

Modality-Specific Considerations

(Include only the subsection applicable to this request. Remove non-applicable subsections.)

For Supplements:

• [Indication linked to diagnosis with objective evidence such as lab deficiency, malabsorption risk, or dietary restriction]
• [Medication interaction review and safety considerations]
• [Brand-specific justification if required, naming the specific excipient allergy or intolerance]

For Medical Foods:

• [Disease or condition with distinctive nutritional requirement]
• [Why needs cannot be met by diet modification alone, with patient-specific barriers]
• [Administration method and medical supervision plan, including RD involvement if applicable]

For Integrative Therapies:

• [Target symptoms and functional goals]
• [Practitioner credentials, setting, and coordination with conventional care]
• [Escalation plan if response is inadequate]
• [Safety considerations or contraindications specific to this modality]

Attachments

• [Relevant progress notes]
• [Lab reports]
• [Registered Dietitian assessment] (If applicable)
• [Prior treatment documentation]
• [Denial letter and payer policy excerpt] (For appeals)

(This letter summarizes and cross-references the attached records.)

Closing

I am available for peer-to-peer review at [direct phone] during [availability window]. [Statement of urgency and clinical risk of delay if applicable.] Thank you for your prompt review.

Attestation: I am the treating clinician and attest that this request is medically necessary for the treatment of the patient's condition as described above.
