CMS modified NCD 342 for tobacco cessation counseling, effective January 9, 2026. Here's what billing teams need to know.
The Centers for Medicare & Medicaid Services updated its coverage policy for tobacco cessation counseling under NCD 342 in its Medicare system. This policy governs outpatient and inpatient counseling benefits for Medicare beneficiaries who use tobacco. The policy does not list specific CPT or HCPCS codes in the current document — but the coverage rules, session limits, and cost-sharing waivers have real billing implications your team needs to understand now.

CMS Tobacco Cessation Counseling Coverage Criteria and Medical Necessity Requirements 2026
CMS covers tobacco cessation counseling under the Additional Preventive Services benefit category. Coverage applies to outpatient and hospitalized Medicare beneficiaries — and three conditions must all be met.
First, the patient must use tobacco. CMS does not require a tobacco-related diagnosis. A patient who smokes but has no current signs or symptoms of a tobacco-related disease still qualifies. That's a broader medical necessity standard than most billing teams assume.
Second, the patient must be competent and alert at the time of counseling. Document this explicitly in the encounter note. If the patient is sedated, confused, or otherwise unable to engage in counseling, the service does not meet the CMS tobacco cessation counseling coverage policy criteria.
Third, the counseling must be furnished by a qualified physician or other Medicare-recognized practitioner. This is not a self-administered benefit. The practitioner must be Medicare-enrolled and eligible to bill Part B.
Once those three criteria are satisfied, CMS covers two counseling attempts per 12-month period. Each attempt allows up to four sessions — either intermediate or intensive. That gives you a total of eight sessions per 12-month period per beneficiary. Know this ceiling. Billing a ninth session will generate a claim denial.
The 12-month period is rolling, not calendar-year-based. Your billing team needs to check prior utilization before each new attempt begins. If a patient had a prior counseling attempt under a different provider, those sessions still count toward the beneficiary's annual limit.
CMS Tobacco Cessation Counseling Session Types and Medical Necessity Distinctions
CMS recognizes two session types under this coverage policy. Each has a defined time threshold, and the threshold matters for reimbursement.
Intermediate sessions run more than three minutes but less than 10 minutes. Intensive sessions run more than 10 minutes. The practitioner and patient can choose either type for any given session. CMS does not require you to escalate from intermediate to intensive — you can mix and match within an attempt.
The real issue here is documentation time. Your encounter notes must support the session length you bill. If you bill an intensive session but the note doesn't reflect more than 10 minutes of counseling time, you're exposed on audit. Build a documentation prompt into your templates now, before January 9, 2026 claims start flowing.
CMS Tobacco Cessation Counseling Exclusions and Non-Covered Indications
CMS is explicit about one non-covered scenario: inpatient hospital stays where tobacco cessation is the principal diagnosis.
If the primary reason a patient is admitted is tobacco use disorder, CMS will not cover tobacco cessation counseling services under that stay. The position is that inpatient admission is not a reasonable or necessary setting for delivering tobacco cessation counseling when that's the only reason for the stay.
This matters most for hospital medicine and utilization review teams. If you're assigning tobacco use disorder as the principal diagnosis on an inpatient claim, and counseling is the primary intervention, expect a denial. The service may still be covered outpatient — but not as the driver of an inpatient stay.
Tobacco cessation counseling delivered during an inpatient stay for a different principal diagnosis is not excluded. A patient admitted for a COPD exacerbation can still receive covered tobacco cessation counseling during that stay.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Tobacco user, outpatient, no tobacco-related diagnosis | Covered | Not specified in policy | Up to 8 sessions per 12-month period across 2 attempts |
| Tobacco user, hospitalized, principal diagnosis is not tobacco use disorder | Covered | Not specified in policy | Same session and attempt limits apply |
| Tobacco user, competent and alert, counseled by qualified Medicare practitioner | Covered | Not specified in policy | All three criteria must be met simultaneously |
| Inpatient stay where principal diagnosis is tobacco use disorder | Not Covered | Not specified in policy | CMS deems inpatient admission not reasonable/necessary for this purpose |
| More than 8 sessions in a 12-month period | Not Covered | Not specified in policy | Hard cap — additional sessions will deny |
| Counseling by non-Medicare-recognized practitioner | Not Covered | Not specified in policy | Practitioner enrollment and recognition required |
CMS Tobacco Cessation Counseling Billing Guidelines and Action Items 2026
| # | Action Item |
|---|---|
| 1 | Audit prior utilization before billing any new attempt. Check each beneficiary's tobacco cessation counseling history in the Medicare system before the first session of a new attempt. A patient who used sessions with another provider still hits the same eight-session annual cap. Billing without checking is how you generate preventable claim denials. |
| 2 | Document session duration in every encounter note. CMS distinguishes intermediate from intensive sessions by time — more than three but fewer than 10 minutes vs. more than 10 minutes. Your documentation must support the session type billed. Add a time-of-counseling field to your note template now. |
| 3 | Confirm the patient is competent and alert at the time of service. This is a hard coverage requirement, not a soft clinical preference. Note it explicitly in your encounter documentation. A brief statement — "patient was alert, oriented, and actively engaged in counseling" — is sufficient and protects your reimbursement on audit. |
| 4 | Verify practitioner eligibility before scheduling counseling. The counseling must be furnished by a Medicare-recognized practitioner. If a counselor on your staff is not Medicare-enrolled, their sessions do not qualify. Check enrollment status and scope before routing patients to any non-physician counselors. |
| 5 | Flag inpatient cases where tobacco use disorder is the principal diagnosis. Work with your utilization review team to identify any cases where tobacco cessation is the primary reason for admission. CMS will not cover tobacco cessation billing under those circumstances. If the patient needs tobacco cessation support, deliver it as an outpatient or as a secondary service during an admission for a different primary condition. |
| 6 | Apply the cost-sharing waiver correctly. Section 4104 of the Affordable Care Act waived Medicare coinsurance and the Part B deductible for this service for dates of service on or after January 1, 2011. If your billing system is still applying standard Part B cost-sharing to tobacco cessation counseling claims, correct that now. Medicare beneficiaries should not be charged coinsurance or the deductible for these services. |
| 7 | Talk to your compliance officer if you bill tobacco cessation across multiple settings. If your organization delivers tobacco cessation counseling in both inpatient and outpatient settings, the principal diagnosis rule creates real exposure. Your compliance officer should review how your team assigns principal diagnosis codes in cases where tobacco cessation is a significant part of the care plan. |

CPT, HCPCS, and ICD-10 Codes for Tobacco Cessation Counseling Under NCD 342
No Specific Codes Listed in Policy Data
NCD 342 does not enumerate specific CPT or HCPCS codes in the current policy document. CMS references claims processing instructions in Transmittal 3848 (Medicare Claims Processing Manual) for coding guidance.
Your billing team should pull the specific tobacco cessation counseling codes from your Medicare Administrative Contractor's guidance and from Transmittal 3848 directly. Don't assume your current charge capture reflects the correct codes without verifying against the transmittal.
If you're uncertain which codes to bill for intermediate vs. intensive tobacco cessation sessions under Medicare Part B, contact your MAC before the effective date of January 9, 2026. Getting the codes wrong is the fastest route to a claim denial that takes months to resolve.
The Cost-Sharing Waiver — Don't Leave Money on the Table
This section often gets overlooked, so it's worth calling out directly. CMS waived the Medicare coinsurance and Part B deductible for tobacco cessation counseling for services delivered on or after January 1, 2011. That waiver has been in place for over a decade.
If your billing system still applies standard Part B cost-sharing to these claims, you are incorrectly billing patients and potentially creating overpayment liability. Audit your system configuration. This is not a theoretical risk — it's an operational gap that shows up in practices that haven't touched their tobacco cessation billing workflow in years.
The waiver also matters for your patient financial counseling team. Make sure front-desk staff know that tobacco cessation counseling is a zero-cost-sharing benefit. Patients who think they'll be billed often decline the service. That's a missed preventive care opportunity and a quality measure miss if you're in a value-based arrangement.
