Other diseases of jaws (M27)
The ICD-10 code M27 covers various diseases affecting the jaws that do not fit into more common categories. This section includes developmental disorders, inflammatory conditions, cysts, complications from dental treatments like root canal therapy, and implant failures specifically related to the jaw bones.
Healthcare professionals use the ICD-10 code for other diseases of jaws (M27) to classify conditions such as developmental jaw abnormalities like exostosis of jaw or torus mandibularis (M27.0), and inflammatory jaw diseases including forms of osteomyelitis and abscesses (M27.2). The code also includes alveolitis (M27.3), various cysts of the jaw (M27.4), and complications related to previous endodontic treatment such as root canal perforations and overfills (M27.5). Additionally, failures of endosseous dental implants like osseointegration failure or mechanical breakdown are coded under M27.6. More specific disorders like giant cell granuloma (M27.1) and other specified diseases, including fibrous dysplasia or cherubism (M27.8), fall within this category. When the exact diagnosis is unclear, M27.9 is used for unspecified jaw diseases, helping coders accurately capture diverse jaw-related conditions encountered in dental and medical practice.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
