When Oral Hygiene Instruction Is More Than a Pep Talk
My office manager was inquiring about charging for oral hygiene instruction (OHI) at every recare appointment. We review and discuss OHI in great detail with every patient, but is this something that we can bill for?

AThe D1330 dental code applies to the services of “oral hygiene instruction” and was updated in 2025. It is intended for personalized, structured education and hands-on training that go beyond the routine oral hygiene guidance typically provided during a prophylaxis or periodontal maintenance visit. The D1330 can be applied when the clinician delivers in-depth instruction tailored to a patient’s particular needs.
Appropriate situations for billing D1330 include patients at high caries risk, those beginning orthodontic treatment, individuals with advanced periodontal diseases who require significant self-care changes, and patients with special needs or physical limitations that necessitate adaptive techniques. Examples include teaching modified brushing and interdental cleaning for a patient with gingival inflammation and recession, instructing a patient on care around braces or other appliances, demonstrating the use of an interdental brush for open embrasures, or explaining the correct use of a prescription antimicrobial or remineralizing agent.
Accurate, detailed documentation is essential when billing D1330. Because this service involves individualized and often measurable education, clinical notes should go beyond a generic template. On the date of service, document the specific reason the instruction was necessary, the oral hygiene challenges identified, and goals of the session. Record which techniques were demonstrated and why they were chosen. Include the method and sequence used during demonstrations. For example: “Demonstrated modified Bass technique with a soft bristled toothbrush for improved gingival margin cleaning due to buccal recession and localized inflammation” and note the patient’s response and competence with the technique.
List any products, aids, or prescription recommendations provided and explain their intended purpose. For instance, document if chlorhexidine rinse was recommended for short-term gingival healing and the instructions given for frequency and duration, or if a fluoride varnish, prescription fluoride toothpaste, or remineralization agent was supplied or prescribed for caries management. When special tools are introduced, such as interdental brushes, floss threaders, powered toothbrushes, water irrigators, or adaptive handles for patients with limited manual dexterity, note the size, model, or type demonstrated and the instruction provided for effective use.
If self-care goals or a follow-up plan were established, document those details. Examples include assigned daily routines, short-term adjunctive therapies, expected improvement timelines, and plans for reassessment at subsequent appointments. Also record any patient education materials given (written instructions, videos, product samples) and whether the patient demonstrated comprehension or technique mastery during the visit.
Insurance coverage for D1330 varies considerably. Many insurance carriers may consider oral hygiene instruction part of routine preventive care and therefore deny separate reimbursement, regardless of the depth or necessity of the instruction. Always verify benefits before billing: confirm whether the carrier recognizes D1330, how frequently it may be billed for the same patient, and whether supporting clinical notes need to accompany the claim. Inform patients in advance about the likelihood of coverage denial and any potential out-of-pocket costs so they can make an informed decision about proceeding.
