The ICD code M246 is used to code Ankylosis
Ankylosis or anchylosis (from Greek ἀγκύλος, bent, crooked) is a stiffness of a joint due to abnormal adhesion and rigidity of the bones of the joint, which may be the result of injury or disease. The rigidity may be complete or partial and may be due to inflammation of the tendinous or muscular structures outside the joint or of the tissues of the joint itself. Noma—a gangrenous disease still widespread among malnourished children living on the borders of the Sahara desert—can cause ankylosis of the maxilla and mandible, impairing the ability to speak and eat.
