Brandon, this is a standard automated denial by third-party administrators (TPAs) whenever an expense is flagged as 'weight loss'. Under IRS Revenue Ruling 2002-19, general weight reduction programs for cosmetic appearance are excluded from IRC Section 213(d), but treatments for medically diagnosed obesity or comorbid conditions are 100% deductible medical care.
The 5 Elements Your Letter of Medical Necessity (LMN) Must Contain: 1. Specific ICD-10 Diagnosis: The letter must state a formal medical diagnosis, such as E66.9 (Obesity, unspecified), E66.3 (Overweight) with comorbidity, or E11 (Type 2 Diabetes). It must never say 'lifestyle weight management'. 2. Objective Biometrics: Baseline BMI (e.g., BMI ≥ 30, or BMI ≥ 27 with hypertension/hyperlipidemia) and vitals recorded by the physician. 3. Medical Treatment Statement: Explicit language stating: *"Tirzepatide is prescribed as active medical treatment to mitigate the clinical progression of metabolic disease and cardiovascular risk factors, and is not for cosmetic purposes."* 4. Treatment Duration: Specific clinical timeframe (e.g., 12 months ongoing chronic therapy). 5. Physician Credentials: Licensed provider signature, state license number, and National Provider Identifier (NPI).
