D0389Intraoral Tomosynthesis - Bitewing - Image Capture Only

What This Code Covers

D0389 covers intraoral tomosynthesis - bitewing - image capture only. This procedure produces diagnostic images that help the dentist identify decay, bone loss, and other conditions not visible during a clinical exam. The images become part of the patient's permanent record and may be required for treatment planning documentation.

Billing Guide

Bill this code when:

• The specific imaging described by D0389 is performed and documented

Do not bill this code when:

• The images are retaken solely due to technical error at the same visit
• A different imaging type or field of view was actually captured
• The image was captured but not of diagnostic quality and must be repeated
• The procedure is better described by D0369 (Maxillofacial MRI capture and interpretation)
