Bilateral temporomandibular joint disorder, unspecified

This code signifies a non-specific disorder affecting both temporomandibular joints (TMJs). It indicates a problem with the jaw joints on both sides, without further detail regarding the specific nature or cause of the dysfunction. This could encompass a range of symptoms such as pain, clicking, limited jaw movement, or tenderness.

This code is appropriate when documentation indicates bilateral TMJ involvement but lacks specific diagnostic details (e.g., osteoarthritis, internal derangement, myofascial pain). It is used when the provider has diagnosed a TMJ disorder affecting both sides but has not specified the exact type. Supporting documentation would typically include notes stating "bilateral TMJ disorder, unspecified" or similar phrasing.

• Avoid using this code if more specific diagnostic information for the bilateral TMJ disorder is available (e.g., M26.623 for bilateral TMJ osteoarthritis).
• Ensure documentation explicitly states "bilateral" involvement; otherwise, a unilateral or unspecified laterality code may be more appropriate.
• Query the provider for greater specificity if possible, as a more precise diagnosis often leads to a more accurate code.
