CMS Tobacco Cessation Counseling Coverage Policy Update (NCD 342): What Billing Teams Need to Know in 2026

The Centers for Medicare & Medicaid Services (CMS) has issued a modification to National Coverage Determination (NCD) 342, governing counseling to prevent tobacco use under Medicare. This update affects how outpatient and inpatient tobacco cessation counseling services are covered, billed, and reimbursed for Medicare beneficiaries. If your practice includes primary care, pulmonology, oncology, or any specialty treating Medicare patients who smoke, this policy directly affects your revenue cycle.

What NCD 342 Covers: CMS Tobacco Cessation Counseling Eligibility

Under NCD 342, CMS covers tobacco cessation counseling for both outpatient and hospitalized Medicare beneficiaries. Coverage is not limited to patients who already show signs or symptoms of tobacco-related disease — any Medicare beneficiary who uses tobacco qualifies, which is a meaningful distinction for preventive-focused practices.

Three conditions must be met for a claim to be covered:

1. The patient uses tobacco, regardless of whether they currently exhibit tobacco-related signs or symptoms.
2. The patient is competent and alert at the time counseling is provided.
3. Counseling is furnished by a qualified physician or other Medicare-recognized practitioner.

This benefit falls under the Additional Preventive Services benefit category under Medicare Part B.

Session Types, Frequency Limits, and the Per-12-Month Benefit Structure

Getting the frequency rules right is critical to avoiding claim denials. CMS allows 2 individual tobacco cessation counseling attempts per 12-month period per Medicare beneficiary. Each attempt may include a maximum of 4 sessions, meaning the total benefit caps at 8 sessions per 12-month period.

Sessions can be either intermediate or intensive — and the practitioner and patient choose which type applies:

• Intermediate: More than 3 minutes but less than 10 minutes
• Intensive: More than 10 minutes

One important operational note: a single attempt may include up to 4 sessions of intermediate or intensive counseling, but the policy does not allow mixing and exceeding that cap of 4 sessions per attempt. Billing teams should track attempt and session counts carefully per beneficiary to avoid hitting the annual limit prematurely or submitting claims beyond it.

What CMS Will NOT Cover Under NCD 342

The non-covered indication under this policy is specific and worth flagging in your utilization review process.

CMS will not cover tobacco cessation counseling services when tobacco cessation is the primary reason for an inpatient hospital stay. The policy states explicitly that inpatient hospital stays with a principal diagnosis of tobacco use disorder are not reasonable and necessary for the effective delivery of these services.

This means if a patient is admitted with tobacco use disorder listed as the principal diagnosis, tobacco cessation counseling billed during that stay will be denied. However, counseling provided to a hospitalized patient whose primary admission diagnosis is something else — a cardiac event, COPD exacerbation, lung cancer — can still qualify if the three eligibility conditions above are met.

Cost Sharing: Deductible and Coinsurance Waiver

This is one of the more beneficiary-friendly aspects of NCD 342 and worth communicating to your front desk and financial counseling teams.

Under Section 4104 of the Affordable Care Act, Medicare waives both the Part B deductible and coinsurance for covered tobacco cessation counseling services. This waiver has been in effect since January 1, 2011. Patients should not be billed for cost-sharing on claims that qualify under this benefit — doing so would create compliance exposure and patient satisfaction issues.

The Public Health Context Behind This Policy

Understanding why CMS maintains and refines this NCD helps billing teams explain its value internally and anticipate future updates.

Tobacco use remains the leading cause of preventable death in the U.S. More than 45 million adults currently smoke, and approximately 1,200 die prematurely each day from tobacco-related diseases. Direct medical costs attributable to smoking run approximately $96 billion annually, with another $97 billion in lost productivity.

For Medicare's population specifically, 4.5 million adults over age 65 smoke — and CMS has recognized that even older smokers benefit significantly from cessation support, reducing risk of death from coronary heart disease, COPD, lung cancer, and osteoporosis. The U.S. Department of Health and Human Services Public Health Service Clinical Practice Guideline on Treating Tobacco Use and Dependence (2008) underpins much of the clinical evidence base for this NCD.

Affected Codes

The updated NCD 342 policy document does not list specific CPT or HCPCS codes in its current version. For the applicable billing codes used to submit tobacco cessation counseling claims under this NCD, consult CMS Claims Processing Transmittal TN 3848, which contains the official claims processing instructions associated with this policy.

Your practice management system vendor or Medicare Administrative Contractor (MAC) can also confirm the correct codes for intermediate and intensive cessation counseling sessions applicable to your region and setting.
