Short lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT)
ICD-10 G44.05 is a billable code used to indicate a diagnosis of short lasting unilateral neuralgiform headache with conjunctival injection and tearing (sunct).
Short lasting unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT) is a rare primary headache disorder characterized by recurrent, brief episodes of unilateral head pain that can last from a few seconds to several minutes. The pain is typically severe and is often accompanied by autonomic symptoms such as conjunctival injection (redness of the eye) and tearing. SUNCT is considered a trigeminal autonomic cephalalgia, which means it involves the trigeminal nerve and is associated with autonomic features. The attacks can occur multiple times a day and may be triggered by various factors, including physical exertion, stress, or changes in temperature. Unlike cluster headaches, which can last for weeks or months, SUNCT episodes are much shorter in duration. Diagnosis is primarily clinical, based on the characteristic symptoms and exclusion of other headache types. Treatment options include preventive medications such as lamotrigine and indomethacin, as well as acute treatments like opioids or local anesthetics. Due to its rarity and specific symptomatology, accurate coding and documentation are crucial for proper management and reimbursement.
