Time-based HCPCS Level II G codes used; service is considered a preventive health benefit covered without copayment/coinsurance/deductible as applicable under preventive benefits.
IBT consists of BMI screening, dietary assessment, and intensive behavioral counseling to promote sustained weight loss.
For purposes of Intensive Behavioral Therapy (IBT) coverage, services must be furnished in a primary care setting by a qualified primary care practitioner. A primary care setting is one that provides integrated, accessible care by clinicians accountable for a majority of personal health care needs and sustaining a patient partnership. The policy specifically excludes the following from being considered primary care settings: emergency departments, inpatient hospital settings, ambulatory surgical centers, independent diagnostic testing facilities, skilled nursing facilities, inpatient rehabilitation facilities, and hospices.
Services that are determined to be not medically necessary or that qualify as non-covered benefits are not payable. Providers may be prohibited from billing members for such services except in circumstances where the member has been informed and provided written agreement in advance to accept financial responsibility. Refer to provider participation agreements for applicable billing restrictions and balance-billing provisions.

- Prior authorization: Not applicable
Coverage and Billing Reminder
Behavioral counseling for obesity is covered when billed using the time-based HCPCS Level II G-codes for obesity-related counseling provided as time-based evaluation and management (E/M) services. When covered as a preventive health benefit under applicable plans, these services may be provided without member copayment/coinsurance and deductible per the member's preventive benefits.
- Applicable plans: Medicare Advantage and Commercial products
- Billing: time-based HCPCS Level II G-codes for obesity counseling
- Benefit: May be covered as preventive health benefit without cost-sharing as applicable
Documentation Requirements
Each IBT for obesity session must follow the USPSTF 5A approach (Assess, Advise, Agree, Assist, Arrange). Because this is a time-based service, medical record documentation must include time-qualifying statements that substantiate the duration of counseling that is part of the IBT service. Do not count time spent on activities outside this service.
- Document use of the 5As framework: Assess, Advise, Agree, Assist, Arrange
- Include time-qualified statements in the medical record to substantiate billed time
- Exclude unrelated activities from the documented session time
Denial and Member Billing Risk
If services are determined not medically necessary or are non-covered benefits, the claim may be denied. Providers should confirm member benefits and eligibility prior to rendering services. Providers may not bill members for non-covered services unless the member was informed in advance and agreed in writing to pay out-of-pocket; see participation agreement provisions for details.
- Non-covered or not medically necessary services: potential claim denial
- Verify member-specific benefits via provider call center before treatment
- Member balance billing allowed only with prior written member consent
Clinical background and policy scope
Obesity prevalence in the United States has risen substantially over recent decades; in the Medicare population more than 30% of men and women are obese, and obesity is associated with many chronic conditions including cardiovascular disease, musculoskeletal disorders, and diabetes. Medicare-defined IBT for obesity applies to adults with a BMI ≥ 30 kg/m2 and includes BMI screening, dietary (nutritional) assessment, and intensive behavioral counseling and therapy to promote sustained weight loss through high-intensity interventions addressing diet and exercise. Coverage is provided when counseling is furnished to competent, alert beneficiaries by qualified primary care practitioners (including specified physician specialties and qualified non-physician practitioners) in a primary care setting.
