D1330Oral Hygiene Instructions

What This Code Covers

D1330 covers individualized oral hygiene instruction provided to a patient. This includes demonstrating proper brushing technique, flossing, use of interdental brushes, water flossers, tongue cleaning, and other home care aids. The instructions are tailored to the patient's specific needs based on their clinical findings. This is a separate service from the prophylaxis and evaluation.

Billing Guide

Bill this code when:

• Dedicated, individualized oral hygiene instruction is provided
• The instruction goes beyond what is routinely included in a preventive visit
• The session includes hands-on demonstration of brushing, flossing, or other techniques
• The instruction is documented with specific home care recommendations

Do not bill this code when:

• Brief oral hygiene reminders are given as part of a routine prophy visit
• No specific instruction session is documented
• The hygienist simply tells the patient to brush and floss without individualized guidance
• The payer bundles oral hygiene instructions into the prophylaxis code

Insurance and Denial Prevention

Key Payer Rules:

• Many payers consider oral hygiene instructions part of the prophylaxis and will not reimburse D1330 separately
• Some Medicaid programs cover D1330 for children and patients with special needs
• When covered, frequency is typically limited to one or two sessions per year
• Documentation must show the instruction was a distinct, dedicated service

Common Denials and How to Respond:

• Bundled with prophylaxis → Most payers consider oral hygiene instruction part of the prophy. If a separate extended session was provided, appeal with documentation.
• Not a covered benefit → Verify coverage. Provide the service as part of routine care if not reimbursable.
• Frequency exceeded → Check the plan's limit and date of last instruction session.
