ICD-10 Code G50.1 – Atypical facial pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G50.1 – Atypical facial pain
What it is
G50.1 identifies atypical facial pain, a chronic facial pain syndrome that does not follow a typical nerve distribution. Use it when the record describes persistent facial pain without a clearer structural or dental cause.
Clinical signs
Clinical features vary; refer to documentation. Notes often describe persistent, poorly localized facial pain, sometimes aching or burning, with no consistent neurologic deficit or classic trigeminal neuralgia pattern.
When to use this code
Use this code when the clinician documents atypical facial pain, persistent idiopathic facial pain, or similar wording and no more specific diagnosis is established. It may also fit when workup excludes dental, sinus, or other identifiable causes. Check documentation if the record is vague.
Do not use for
Do not use G50.1 for trigeminal neuralgia, dental pain, sinus-related pain, or facial pain with an identified cause. If the chart names another condition, code that diagnosis instead.
Coding tip
Code G50.1 only when the provider explicitly documents atypical facial pain or an equivalent diagnosis after evaluation.
