Cysts found in the jaws and arising from epithelium involved in tooth formation. They include follicular cysts (e.g., primordial cyst, dentigerous cyst, multilocular cyst), lateral periodontal cysts, and radicular cysts. They may become keratinized (odontogenic keratocysts). Follicular cysts may give rise to ameloblastomas and, in rare cases, undergo malignant transformation. Most common follicular odontogenic cyst. Occurs in relation to a partially erupted or unerupted tooth with at least the crown of the tooth to which the cyst is attached protruding into the cystic cavity. May give rise to an ameloblastoma and, in rare instances, undergo malignant transformation. 526.0 is a specific code that can be used to specify a diagnosis 526.0 contains 20 index entries ICD-9-CM Diagnosis 526.1 Fissural cysts of jaw 526.1 is a specific code that can be used to specify a diagnosis 526.1 contains 15 index entries ICD-9-CM Diagnosis 526.2 Other cysts of jaws Saccular lesions lined with epithelium and contained within pathologically formed cavities in the jaw; also nonepithelial cysts (pseudocysts) as they apply to the jaw, e.g., traumatic or solitary cyst, static bone cavity, and aneurysmal bone cyst. True jaw cysts are classified as odontogenic or nonodontogenic. 526.2 is a specific code that can be used to specify a diagnosis 526.2 contains 8 index entries ICD-9-CM Diagnosis 526.3 Central giant cell (reparative) granuloma 526.3 is a specific code that can be used to specify a diagnosis 526.3 contains 4 index entries ICD-9-CM Diagnosis 526.4 Inflammatory conditions of jaw 526.4 is a specific code that can be used to specify a diagnosis 526.4 contains 19 index entries ICD-9-CM Diagnosis 526.5 Alveolitis of jaw A condition sometimes occurring after tooth extraction, particularly after traumatic extraction, resulting in a dry appearance of the exposed bone in the socket, due to disintegration or loss of the blood clot. It is basically a focal osteomyelitis without suppuration and is accompanied by severe pain (alveolalgia) and foul odor. 526.5 is a specific code that can be used to specify a diagnosis 526.5 contains 12 index entries ICD-9-CM Diagnosis 526.8 Other specified diseases of the jaws 526.8 is a non-specific code that cannot be used to specify a diagnosis ICD-9-CM Diagnosis 526.81 Exostosis of jaw 526.81 is a specific code that can be used to specify a diagnosis 526.81 contains 3 index entries ICD-9-CM Diagnosis 526.89 Other specified diseases of the jaws A fibro-osseous hereditary disease of the jaws. The swollen jaws and raised eyes give a cherubic appearance; multiple radiolucencies are evident upon radiographic examination. 526.89 is a specific code that can be used to specify a diagnosis 526.89 contains 14 index entries ICD-9-CM Diagnosis 526.9 Unspecified disease of the jaws 526.9 is a specific code that can be used to specify a diagnosis 526.9 contains 3 index entries
