ICD Code G50.1

ICD code G50.1 is atypical facial pain, a chronic pain condition affecting the face that does not have a clear cause and does not fit the typical patterns of other facial pain disorders.

1. Persistent facial pain that does not have the characteristics of classical trigeminal neuralgia

2. Pain is poorly localized and does not follow the distribution of a single nerve

3. Pain is described as dull, aching, or nagging rather than sharp or electric

4. Duration of pain is continuous or nearly continuous, often lasting for months or years

5. No objective neurological deficit is found on examination

6. Pain is not associated with clinical or radiological evidence of a dental or sinus disorder

7. Other causes of facial pain, such as temporomandibular joint disorders or cluster headaches, have been excluded
