Meningococcal retrobulbar neuritis

This code describes inflammation of the optic nerve behind the eyeball (retrobulbar neuritis) specifically caused by a meningococcal infection. It indicates a neurological complication directly resulting from Neisseria meningitidis involvement.

Use this code when documentation clearly states retrobulbar neuritis as a sequela or manifestation of a confirmed meningococcal disease. The patient's medical record should specify the infectious agent as meningococcal.

• Always sequence the underlying meningococcal infection code first, followed by this code for the neurological manifestation.
• Ensure documentation explicitly links the retrobulbar neuritis to meningococcal etiology; avoid using for unspecified or other infectious causes.
• Distinguish from other forms of optic neuritis (e.g., demyelinating, autoimmune) which have different code assignments.
