D3450—Root amputation, per root
After reading this article, you will understand when to bill for a root amputation and how to successfully code for the procedure being performed. Let's start by understanding the CDT description, which defines the use and purpose.
According to the CDT, a root amputation is considered an endodontic procedure in which removal of a single root is performed. Root(s) of the same tooth will remain in the patient's dentition even after the procedure is completed. This code is typically reported for a multi-rooted tooth, i.e., posterior molar.
Let’s discuss limitations and reasons for denial
• If an apicoectomy is performed in addition to the root amputation, reimbursement is limited to only one procedure, not both.
• If you bill an extraction in addition to the root amputation, reimbursement is limited to one procedure, not both, and it's usually the lesser fee that will be paid.
• Additional roots and teeth should always be reported separately.
• Ridge augmentation and bonegraft preservation should be reported separately.
Common coding errors
• Providing pre- and post-op x-rays.
• Failing to provide reasons of necessity.
• Failing to provide periodontal charting and a full set of x-fays within the last six months.
It is always recommended that you preauthorize dental treatment to ensure coverage.
