350.2
ICD-9-CMThis code describes persistent facial pain that does not conform to the typical patterns of other recognized facial pain syndromes, such as trigeminal neuralgia or temporomandibular joint dysfunction. It is characterized by a deep, aching, or burning sensation, often poorly localized, without objective sensory loss or autonomic features.
Use this code when documentation clearly indicates facial pain that is chronic, idiopathic, and lacks the specific diagnostic criteria for other classified facial pain conditions. It is appropriate when extensive workup has ruled out dental, sinus, neurological, or musculoskeletal causes.
