Adhesions and ankylosis of bilateral temporomandibular joint

This code signifies the presence of abnormal fibrous bands (adhesions) and/or fusion (ankylosis) affecting both the left and right temporomandibular joints. These conditions restrict normal jaw movement, leading to pain, limited opening, and difficulty with mastication.

Apply this code when documentation explicitly states bilateral temporomandibular joint adhesions and/or ankylosis. This typically arises from trauma, infection, or inflammatory conditions affecting the joint. Supporting documentation should include imaging reports (e.g., MRI, CT) confirming the bilateral nature and the specific pathology.

• Ensure the documentation clearly specifies bilateral involvement; otherwise, use a code for unilateral involvement.
• Distinguish between adhesions and ankylosis, though this code covers both.
• Consider sequencing this code with an external cause code if the condition is due to trauma.
