Arthropathy of bilateral temporomandibular joint

This code signifies a non-inflammatory joint disorder affecting both temporomandibular joints (TMJs). It encompasses degenerative changes, internal derangement, or other non-inflammatory conditions leading to pain, limited range of motion, or dysfunction in both TMJs.

Apply this code when documentation clearly indicates an arthropathy affecting both the left and right temporomandibular joints. This is supported by physician notes detailing bilateral TMJ pain, crepitus, clicking, locking, or imaging findings consistent with degenerative changes or internal derangement in both joints.

• Ensure documentation specifies bilateral involvement; otherwise, use a code for unilateral or unspecified TMJ arthropathy.
• Distinguish from inflammatory conditions of the TMJ (e.g., M05.79) or other specific TMJ disorders (e.g., M26.62- for disc disorders).
• Code any associated pain (e.g., G89.11, G89.21) or other symptoms separately, if documented.
