Removal of a tooth that is partially covered by bone, requiring mucoperiosteal flap elevation and bone removal.
Get help with D7230 claims →Third molars that are partially erupted with bone covering a portion of the crown.
Impacted teeth associated with cysts, infection, or damage to adjacent teeth.
Impacted teeth that need to be removed as part of orthodontic treatment planning.
These are the denial reasons we see most often for D7230. Each one is preventable with proper documentation.
The payer reviews the radiograph and determines a different impaction classification. D7230 (partial bony) may be downgraded to D7220 (soft tissue) or upgraded to D7240 (full bony).
If sedation was used, the anesthesia code may be denied separately depending on the plan.
Some plans limit the number of impacted tooth removals per date of service.
Panoramic or periapical showing the impaction classification.
Document the position: mesioangular, distoangular, horizontal, vertical. Note how much bone covers the tooth.
Record flap design, amount of bone removed, tooth sectioning if performed, and closure.
The impaction code depends on how much bone covers the tooth. D7220 is soft tissue impaction (tooth is covered by gingival tissue only). D7230 is partial bony impaction (bone covers part of the crown). D7240 is complete bony impaction (bone covers the entire crown). The pre-operative radiograph determines the classification.
Payers frequently reclassify impaction levels after reviewing the radiograph. If you bill D7240 (full bony) but the radiograph shows the tooth is partially erupted through bone, the claim will be downgraded to D7230. Always classify the impaction based on what the radiograph shows, not based on the difficulty of the surgery.
In your operative note, describe exactly what you found: "Crown was covered by bone on the mesial, distal, and occlusal surfaces. A buccal flap was raised and approximately 4mm of overlying bone was removed with a surgical handpiece to expose the crown." This level of detail supports the impaction classification and makes downgrades harder for the payer to justify.
