99406/99407: the counseling minutes payers actually cover

Does 99406 or 99407 get paid?

Both codes are payable by Medicare and by most commercial and Medicaid plans, but payment depends on three things lining up: the counseling time actually documented in the note, a diagnosis code that supports tobacco-use counseling, and the payer's own frequency and eligibility rule for the benefit. None of the three is optional, and a mismatch on any one is the usual reason a claim denies rather than pays at face value.

CPT — the code set both codes belong to — is maintained and updated annually by the AMA's CPT Editorial Panel, the same body that governs every other procedure code on the claim 1Ref 1American Medical Association (2026).CPT® (Current Procedural Terminology).That CPT, including the smoking and tobacco-use cessation counseling codes 99406 and 99407 and their defining time thresholds, is maintained and updated annually by the AMA CPT Editorial Panel.. That matters here because the two codes are defined purely by counseling time, not by what was discussed or how the conversation went, so getting the tier right is a documentation habit, not a judgment call.

A useful gut-check before submitting the claim is whether a stranger reading only the note could identify which tier was billed and why, without seeing the code on the claim form itself. A note that says only "discussed quitting smoking" supports neither tier convincingly, because the tier follows documented minutes, not the fact that a conversation happened. Building that gut-check into the visit — writing the actual time spent as part of finishing the note, rather than reconstructing it later from how long the appointment was scheduled for — is what keeps the coding decision defensible months after the fact, if a payer or an auditor ever asks.

99406 vs 99407 — the counseling-time split

CPT distinguishes the two codes only by counseling time: 99406 is the intermediate tier, defined as more than three minutes up to ten minutes of counseling, and 99407 is the intensive tier, defined as more than ten minutes, with both time thresholds published in the same AMA CPT code set 1Ref 1American Medical Association (2026).CPT® (Current Procedural Terminology).That CPT, including the smoking and tobacco-use cessation counseling codes 99406 and 99407 and their defining time thresholds, is maintained and updated annually by the AMA CPT Editorial Panel.. Topic, outcome, or how much the patient engaged has no bearing on which code is correct — only the minutes documented do.

Billing 99407 for a conversation that actually ran short is the kind of mismatch a payer's own time-based review can catch on the note alone — the fix is documenting the actual minutes spent, not just writing "counseled on smoking cessation" and picking whichever code pays more.

A common, avoidable failure mode is an EHR template or smart-phrase that defaults to the same tier every time regardless of the actual conversation — one built to always populate the intensive tier is documenting a number nobody timed, which creates the exact mismatch a payer's review is built to catch, just automated instead of manual. The fix isn't necessarily abandoning templates; it's making sure whichever one is used still requires an actual minute count to be entered rather than defaulting silently to whichever code happens to pay more.

Pairing the code with a diagnosis that supports it

A claim for 99406 or 99407 needs a diagnosis that names tobacco use or dependence as the reason for the counseling — most practices reach for the nicotine dependence category or a tobacco-use-counseling code, chosen for the specific patient rather than copied from a template. ICD-10-CM is updated annually, with the current-year files published by CMS and NCHS, so a code copied from last year's note may not be the current one 2Ref 2Centers for Medicare & Medicaid Services (2026).ICD-10 Codes.That ICD-10-CM is the HIPAA-mandated diagnosis code set, updated annually with files published by CMS/NCHS, so the tobacco-use diagnosis paired with 99406/99407 should be confirmed against the current year's file..

Submitting the counseling code with an unrelated primary diagnosis and no tobacco-use code attached is effectively asking the payer to guess why the counseling happened — and payers that can't tell from the claim alone tend to deny it rather than infer it.

Billing counseling and an E/M visit on the same day

When the counseling happens during an office visit that also addresses another problem, 99406/99407 is reported in addition to the E/M code, not instead of it — but the E/M level still has to be independently justified by its own medical decision making or total time under the 2021 framework, separate from the counseling 3Ref 3American Medical Association (2023).CPT evaluation and management (E/M) revisions.That the 2021+ E/M framework sets office-visit levels by medical decision making or total time, used here to explain that a same-day E/M code billed alongside counseling still needs its own independent justification.. The note needs to show both: what supported the E/M level, and what was actually said during the counseling minutes being billed separately.

When the visit is genuinely just the counseling, with no other problem addressed, there's no separate E/M code to bill at all — reporting an E/M level built on nothing but the counseling conversation is the same tier mismatch as billing 99407 for a nine-minute conversation, just on the other code.

Checking coverage before you bill

Session limits and eligibility rules for tobacco-cessation counseling vary by payer and by plan, so confirming the current national and locality payment amount through CMS's public fee schedule lookup tool is worth doing before assuming a rate 4Ref 4Centers for Medicare & Medicaid Services (2026).Physician Fee Schedule Search.That CMS publishes a public fee schedule look-up tool showing the current national and locality payment amount for a code, used here as the method for confirming what 99406/99407 currently pay rather than assuming a rate., and checking whether a jurisdiction has published its own local coverage article on the topic through the Medicare Coverage Database is worth doing before assuming a frequency limit 5Ref 5Centers for Medicare & Medicaid Services (2026).Medicare Coverage Database (MCD) Search.That NCDs and MAC-specific coverage articles are searchable in the public Medicare Coverage Database, used here as the lookup method for jurisdiction-specific frequency or documentation rules for tobacco-cessation counseling..

If a specific patient has already used up a plan's covered sessions for the benefit period, that's not a reason to bill anyway and hope — for Medicare fee-for-service, giving the patient an Advance Beneficiary Notice before the visit is the mechanism for disclosing that the service is likely to be denied, so the patient can decide whether to proceed knowing they may owe the cost 6Ref 6Centers for Medicare & Medicaid Services (2026).Beneficiary Notices Initiative (BNI).That an Advance Beneficiary Notice is the mechanism for telling a Medicare patient in advance that a service is likely to be denied, used here for the case where a benefit's session limit for the period has likely already been met..

Reading the denial if it comes back unpaid

If a claim for 99406 or 99407 denies, the remittance carries a Claim Adjustment Reason Code that names the actual reason — a diagnosis mismatch, a frequency limit already met, or a bundling conflict with another same-day service each show up as a different CARC, maintained on a public list 7Ref 7X12 (2026).Claim Adjustment Reason Codes.That CARCs are the standard, publicly maintained code list explaining why a claim paid differently than billed, used here as the method for diagnosing which requirement caused a 99406/99407 denial.. Reading that code before resubmitting tells you which of the three requirements — time, diagnosis, or frequency — actually tripped the denial.

Resubmitting an unchanged claim and hoping it clears the second time wastes a billing cycle; resubmitting after fixing the specific element the CARC names is usually the faster path to getting paid.
