D3330: Endodontic Therapy, Molar Tooth (Excluding Final Restoration)
Definition
D3330 is the CDT code for root canal treatment on a molar, not including the filling or crown placed afterward.
Why it matters for the front desk
Root canals are classified as basic services by some plans and major services by others, which changes the patient's share. Because the final restoration is billed separately, the patient often faces a root canal and a crown in quick succession, which can use up much of the annual maximum. Checking the plan's category, waiting period and remaining maximum before treatment helps the team present both costs together.
