Subject: Letter of Medical Necessity – Enteral Nutrition / Medical Food for [tube feeding formula / oral medical food / modular / supplies / pump]

Requested Start Date and Duration: [Start date, requested duration]

Dear [Utilization Management Reviewer / Medical Director]:

Executive Summary

[Primary diagnosis and functional nutrition impairment] (In 1–2 short paragraphs, connect the medical condition to the functional deficit—dysphagia with aspiration risk, malabsorption, inability to maintain weight, or metabolic/genetic disorder. State that the patient requires [tube-administered / oral] enteral nutrition to maintain weight and strength. Document that standard diet modification and oral alternatives have been inadequate, intolerable, or unsafe. Specify the exact product requested and anticipated duration.)

Diagnoses and Relevant History

• [Primary diagnosis]: [ICD-10 code] (Order by relevance to nutrition need.)
• [Secondary diagnosis]: [ICD-10 code] (Include only if it materially affects nutrition need, formula choice, or administration method.)
• [Additional relevant diagnoses]: [ICD-10 codes] (Include only if relevant.)

Relevant Surgical/Anatomic History: [Procedure(s) and dates—PEG/PEJ placement, bowel resection with length, anatomic anomalies]

Feeding Access: [Current access device type, size, placement date] (Include only if tube-fed.)

Allergies/Intolerances Impacting Formula Selection: [Severe allergy or intolerance requiring specialty formula] (Include only if applicable.)

Clinical Status and Functional Indication

[Functional basis for inability to meet nutrition needs normally] (Describe swallowing impairment, GI impairment affecting digestion/absorption, feeding safety concerns, and clear statement of inability to meet needs orally.)

• Swallowing/Feeding Safety: [VFSS/FEES results with date, aspiration/penetration findings, recommended consistencies] (Include only if applicable.)
• GI Function: [Motility disorder, malabsorption, obstruction, inflammatory disease, pancreatic/hepatic insufficiency, post-surgical physiology with diagnostic tests and dates]
• Objective Nutrition Data:
  • Weight trend: [Specific weights with dates; for pediatrics include percentiles and growth velocity; BMI if applicable]
  • Intake estimate: [Percent of estimated needs met orally, method of estimation] (If exact intake unknown, provide best estimate with data source.)
  • Tolerance/outputs: [Stool pattern, emesis frequency, hydration status with dates]
  • Pertinent labs/studies: [Labs with dates, endoscopy/imaging findings with dates] (Include only if they support nutrition need.)

Prior Alternatives and Tolerance Issues

(This section is critical for coverage. List each alternative attempted with dates and outcomes. If trials would be unsafe or contraindicated, document why instead.)

• Diet/Texture Modifications: [Date range, specific textures/strategies, outcome and clinical significance]
• Oral Supplements: [Product(s), amounts, date range, tolerance and outcomes] (Document symptoms—diarrhea, reflux/aspiration, glycemic instability, allergic reaction—with severity, timing, and clinical impact.)
• Standard Enteral Formulas Trialed: [Product(s), concentration, route, date range, volumes/rates, outcomes] (Detail intolerance symptoms and objective findings.) (Include only if applicable.)
• Rationale for Requested Product: [Tie formula characteristics to patient needs—peptide-based for malabsorption, amino acid for severe intolerance/allergy, disease-specific composition for metabolic disorders]

Requested Therapy

• Formula/Medical Food: [Brand name, product category (polymeric / peptide-based / elemental / metabolic formula / blenderized / modular), concentration, planned daily caloric/protein provision]
• Route and Access: [Oral / Tube—if tube: NG / GT / GJ / J-tube with device size and type]
• Administration Method: [Bolus / Gravity / Pump], [Continuous / Cyclic], [Rate in mL/hr, total daily volume, water flush regimen if applicable]
• Equipment and Supplies: [Pump with model if requested, feeding supply kits, tubing, syringes, replacement frequency and monthly quantities]
• Duration: [Temporary / Long-term / Indefinite] with rationale
• Pump Justification: [Reason gravity/syringe is inadequate—aspiration risk, severe reflux, required low infusion rate, dumping/glucose fluctuations, precise dosing needs] (Include only if pump requested.)
• Titration Plan: [Starting regimen, stepwise titration schedule, maximum daily goal] (Include only if titration planned.)

Medical Food Attestations

(Include this section only when requesting a product classified as a medical food for metabolic or genetic disorders.)

• Disease/Condition and Distinctive Nutritional Requirement: [Condition and specific nutrient profile required as determined by medical evaluation]
• Physician Supervision: [Affirmation of ongoing physician oversight and medical follow-up]
• Why Conventional Foods/Supplements Are Inadequate: [Explanation of why standard foods/supplements cannot meet the required nutrient composition safely or effectively]

Monitoring Plan

• Efficacy Monitoring: [Weight frequency, growth parameters if pediatric, hydration status, tolerance metrics, responsible clinician]
• Complication Surveillance: [GI symptoms, tube-site assessment, respiratory symptoms if aspiration risk]
• Laboratory Monitoring: [Labs and frequency if indicated] (Include only if clinically relevant.)
• Follow-Up Schedule: [Follow-up cadence with treating clinician/RD/specialty clinic, criteria for regimen adjustments]

Attachments

(List documents attached or available upon request with dates.)

• [Recent clinic note(s)]
• [Registered Dietitian assessment/nutrition care plan]
• [Swallow study report if applicable]
• [Operative/procedure notes]
• [Growth chart or weight trend summary]
• [Pertinent laboratory results]
• [Discharge summary if relevant]
• [Signed prescription/order for formula/equipment/supplies]

Attestation and Signature

I attest that the above-requested enteral nutrition/medical food, supplies, and equipment are medically necessary to treat the patient's condition and are part of an active plan of care under ongoing medical supervision. The information provided is accurate to the best of my knowledge and will be updated if additional details become available.
