Hemorrhage in optic nerve sheath, unspecified eye

This code signifies bleeding within the protective sheath surrounding the optic nerve, without specifying which eye is affected. This condition can lead to optic nerve compression and visual impairment.

Apply this code when documentation indicates a hemorrhage within the optic nerve sheath but does not specify laterality (e.g., "optic nerve sheath hemorrhage"). This is often diagnosed via imaging studies such as MRI or CT scans.

• Ensure documentation clearly states "unspecified eye" or lacks laterality for accurate code assignment.
• If laterality is known, use the more specific codes (H47.021 for right eye, H47.022 for left eye).
• Consider sequencing this code after the underlying cause of the hemorrhage, if identified and documented.
