ICD10 code of Ameloblastoma and ICD9 code

Ameloblastoma is classified under the ICD-10-CM code D16.5 (Benign neoplasm of lower jaw bone) or D16.4 (Benign neoplasm of skull and face bones), depending on the specific location of the tumor. Under the older ICD-9-CM system, Ameloblastoma was typically coded as 213.1 for the lower jaw or 213.0 for the upper jaw/skull.

What exactly is Ameloblastoma?

Ameloblastoma is a rare, benign, but locally aggressive odontogenic tumor that arises from the cells involved in tooth formation. Although it is classified as benign, Ameloblastoma is notorious for its tendency to invade surrounding tissues, including the jawbone and, in rare cases, nearby soft tissues. Because of its high rate of recurrence, it requires careful surgical management.

How is Ameloblastoma diagnosed and classified?

Diagnosis of Ameloblastoma usually involves a combination of clinical examination, radiographic imaging (such as panoramic X-rays or CT scans), and a definitive biopsy. Pathologists classify Ameloblastoma into several histological subtypes, which can influence the surgical approach:

• Solid/Multicystic Ameloblastoma: The most common and aggressive form.


• Unicystic Ameloblastoma: Often presents as a single cyst; may have a better prognosis.


• Peripheral Ameloblastoma: Occurs in the soft tissues of the gums rather than the bone.


• Metastasizing Ameloblastoma: A rare variant where the tumor spreads to distant sites, typically the lungs.

What is the impact on the community?

Living with Ameloblastoma can be emotionally challenging due to the potential for facial disfigurement and the need for complex reconstructive surgeries. At DiseaseMaps.org, we have 29 community members who have shared their experiences, providing a space for those navigating the diagnostic and recovery phases to find support and shared knowledge.

Next steps
