D1320 is the CDT code for tobacco counseling for the control and prevention of oral disease. It covers a dedicated session in which the clinician discusses the patient's tobacco or nicotine product use and its effects on oral health, including periodontal disease, oral cancer risk, impaired healing, and staining. All tobacco and nicotine product types are covered under this code.

D1320 applies whenever a patient uses any form of tobacco or nicotine product and the clinician provides a dedicated counseling session. This includes cigarettes, cigars, pipe tobacco, chewing tobacco, snuff, and electronic cigarettes. The counseling must address the oral health impact of use and provide cessation guidance or referral.
Tobacco use is a significant risk factor for periodontal disease and impaired healing after treatment. For patients undergoing scaling and root planing or periodontal maintenance, tobacco counseling is clinically appropriate at each visit. Documentation of D1320 alongside periodontal codes demonstrates a comprehensive approach to disease management.
Patients with tobacco-related mucosal changes such as leukoplakia, nicotine stomatitis, or palatal erythema should receive formal counseling. Billing D1320 in these cases creates a documented record that cessation counseling was provided as part of the clinical response to the finding.
Many commercial dental plans do not include D1320 as a covered benefit. Some patients may have tobacco cessation coverage under their medical insurance instead. Before billing, verify dental benefits and also ask whether the patient's medical plan covers tobacco counseling as a separate benefit.
Some plans consider brief tobacco counseling to be included in the exam or cleaning fee. If the plan bundles D1320 with D1110 or D0120 on the same date, attach a narrative describing the counseling as a distinct, time-identified service with specific content beyond routine oral hygiene instruction.
If the patient record does not document current tobacco use, the payer has grounds to question the medical necessity of the counseling code. The clinical note must confirm the patient's tobacco use status and the type of product used before the counseling session is described.
Plans that cover D1320 often limit it to a set number of sessions per year. Verify the frequency allowed before billing multiple sessions in the same plan year.
Record the patient's current tobacco or nicotine product use: type of product, frequency of use, and duration of use history.
Document clinical observations connected to tobacco use: periodontal status, mucosal changes, staining, or other findings discussed during the session.
Describe what was discussed: oral health risks of tobacco use, cessation strategies reviewed, and patient's stated readiness to quit or reduce use.
Note any cessation resources, referrals, or pharmacotherapy discussions offered. A referral to a physician or cessation program strengthens the record.
Record the approximate time spent on the counseling session and identify the clinician who performed it.
