Arthralgia of temporomandibular joint, unspecified side

This code signifies pain in the temporomandibular joint (TMJ) without a specified underlying cause or laterality. It indicates a symptom of joint discomfort in the jaw, rather than a specific TMJ disorder.

This code is appropriate when a patient presents with TMJ pain, and the provider's documentation does not specify which side (left or right) is affected, or the pain is bilateral but the specific etiology is unknown. It should be used when the diagnosis is limited to arthralgia and no further diagnostic information is available at the time of coding.

• Avoid using this code if the laterality of the TMJ pain is documented (e.g., left, right, bilateral); instead, select a more specific code.
• Do not use this code if a more definitive diagnosis for the TMJ pain, such as internal derangement or osteoarthritis, is documented.
• Consider sequencing this code after a more definitive diagnosis if the arthralgia is a symptom of another condition.
