Coverage for weight loss treatment and GLP-1 medications through Humana in Illinois typically falls under medical or pharmacy benefits. Weight loss treatment is not subject to the Mental Health Parity and Addiction Equity Act (MHPAEA), so coverage structures may differ significantly between plan types. Humana offers commercial, Medicare Advantage, and marketplace plans in Illinois, each with potentially different approaches to obesity management benefits.
Humana offers several plan types in Illinois that may include weight loss or obesity management benefits:
GLP-1 Medication Coverage: FDA-approved GLP-1 medications for weight management — such as semaglutide (Wegovy) and tirzepatide (Zepbound) — may be covered under Humana’s pharmacy benefit when prescribed for obesity. Prior authorization is commonly required, along with documentation of qualifying BMI criteria and medical necessity. Note that Medicare Part D generally does not cover weight loss medications, though this may be subject to change. Verify specific Medicare Advantage coverage with Humana.
Prior Authorization: Prior authorization is typically required for GLP-1 weight loss medications under Humana plans in Illinois. Confirm requirements and qualifying criteria with Humana before starting treatment.
Deductibles and Copays: Cost-sharing for weight loss services and GLP-1 medications varies by plan tier and pharmacy benefit design. Review your Summary of Benefits and Coverage for your specific cost-sharing obligations.

Referral requirements for weight loss treatment with Humana in Illinois depend on your plan type. HMO plans may require a referral from a primary care physician to access specialist weight management services. PPO plans often allow direct access.

Many Humana plans in Illinois may cover online weight loss treatment through telehealth platforms. Illinois telehealth parity laws may require that covered weight management services be available through telehealth comparably to in-person care.
