Central giant cell (reparative) granuloma

This code represents a benign, non-neoplastic lesion of the jawbones characterized by a proliferation of multinucleated giant cells within a fibrous stroma. It is considered a reactive process, often occurring in response to local trauma or inflammation, and can cause bone destruction and expansion.

Use this code for documented cases of central giant cell granuloma affecting the mandible or maxilla. Supporting documentation should include pathology reports confirming the diagnosis, imaging studies (e.g., X-rays, CT scans) demonstrating the lesion's location and characteristics, and clinical notes detailing the patient's symptoms and findings.

• Differentiate from peripheral giant cell granuloma, which arises from the gingiva or alveolar mucosa and has a different ICD-9-CM code.
• Ensure the pathology report explicitly states "central" to support the use of this code.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, such as for biopsy or surgical excision.
