Gingival Flap Procedure - CDT Code Guide
Overview
CDT Code D4240 refers to the gingival flap procedure, a surgical intervention in periodontics aimed at treating periodontal disease. This procedure involves the reflection or resection of a soft tissue flap to allow thorough debridement of the root surface and removal of granulation tissue. It is typically performed in cases with moderate to deep probing depths, loss of attachment, or when there is a need for enhanced access to the root surface and alveolar bone. The procedure may also be necessary for aesthetic reasons or to assess the presence of a cracked tooth or fractured root. Techniques such as open flap curettage, reverse bevel flap surgery, and modified Widman surgery may be included under this code. It is important to note that osseous recontouring is not performed in conjunction with this procedure.
When to Use This Code
- Presence of moderate to deep periodontal probing depths
- Loss of attachment requiring intervention
- Need for increased access to the root surface and alveolar bone
- Aesthetic considerations in periodontal treatment
- Assessment of potential cracked tooth or fractured root
Documentation Requirements
- Detailed periodontal charting showing probing depths
- Clinical notes on the necessity of the procedure
- Pre-operative and post-operative photographs if applicable
- Documentation of patient consent for surgical intervention
- Description of the specific surgical technique used
- Any concurrent procedures performed and their respective codes
Billing Considerations
Ensure that the procedure is justified by clinical findings such as probing depths and attachment loss. Be aware of frequency limitations imposed by insurance providers, and consider using modifiers when additional procedures are performed concurrently. Verify coverage with the patient's insurance plan as periodontal surgeries may have specific policy guidelines.
