H47.4 — Disorders of optic chiasm

Not billable

Is H47.4 billable?

No — H47.4 is a non-billable header code. H47.4 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 4 billable codes beneath H47.4.
