Oth disorders of optic nerve, NEC, bilateral

This code signifies a non-specific disorder affecting both optic nerves that isn't better categorized by more precise ICD-10-CM codes. It indicates a bilateral optic neuropathy or dysfunction where the underlying etiology or specific type of optic nerve involvement is not clearly defined or falls outside other specific classifications.

Use this code when documentation indicates a bilateral optic nerve disorder that does not fit more specific diagnoses like optic neuritis, ischemic optic neuropathy, or optic atrophy. This code is appropriate for conditions such as bilateral optic disc edema of unknown etiology, or other generalized bilateral optic nerve dysfunctions where a more precise diagnosis is not yet established or available.

• Ensure documentation explicitly states the condition affects both optic nerves; otherwise, a unilateral code (H47.091 or H47.092) or unspecified code (H47.099) may be more appropriate.
• Avoid using this code if a more specific diagnosis for the bilateral optic nerve disorder is available (e.g., H46.02 for bilateral optic neuritis).
• Always review the medical record for any underlying systemic conditions that might be causing the optic nerve disorder, and code those primary diagnoses first if applicable.
