Anatomical Crown Exposure - CDT Code Guide
Overview
CDT Code D4231 refers to the anatomical crown exposure procedure, which is performed on one to three teeth or bounded tooth spaces per quadrant. This surgical service is typically employed in areas that are otherwise periodontally healthy, where there is a need to remove enlarged gingival tissue and supporting bone through ostectomy. The goal is to establish an anatomically correct gingival relationship, which can be crucial for both aesthetic and functional outcomes. This procedure is often necessary when excessive gingival tissue obscures the crown of the tooth, potentially affecting oral hygiene, aesthetics, or the fit of dental restorations. Dental professionals might consider this procedure in cases where gingival overgrowth is present due to medication, genetics, or other factors, and where traditional periodontal therapies are insufficient.
When to Use This Code
- When gingival overgrowth obscures the crown of the tooth affecting aesthetics or function
- In preparation for restorative dental procedures where proper crown exposure is necessary
- In cases of medication-induced gingival hyperplasia
- To correct anatomical discrepancies in gingival contour
- When traditional periodontal therapies are not sufficient to manage gingival overgrowth
Documentation Requirements
- Detailed clinical notes describing the periodontal health of the area
- Pre-operative and post-operative photographs
- Radiographic evidence supporting the need for bone removal
- Patient consent form acknowledging understanding of the procedure
- Documentation of any previous periodontal treatments
- Detailed charting of the teeth and areas involved
Billing Considerations
When billing for D4231, ensure that the procedure is justified by the clinical scenario and documented thoroughly. Be aware of any frequency limitations imposed by insurance carriers, and consider using appropriate modifiers if the procedure is part of a larger treatment plan. It is important to verify coverage with the patient's insurance provider, as some plans may have specific guidelines or restrictions regarding periodontal surgical services.
