Hereditary optic atrophy

This code describes a group of inherited disorders characterized by progressive degeneration of the optic nerve, leading to vision loss. It encompasses various forms of hereditary optic neuropathy, such as Leber's hereditary optic neuropathy (LHON) and dominant optic atrophy (DOA). The condition typically presents with bilateral, symmetrical vision impairment, often starting in childhood or adolescence.

Use this code when documentation confirms a diagnosis of hereditary optic atrophy, based on clinical findings, family history, and/or genetic testing. This code is appropriate for patients presenting with progressive, unexplained vision loss with a suspected or confirmed genetic etiology affecting the optic nerve. Supporting documentation should clearly indicate the hereditary nature of the optic atrophy.

• Differentiate from acquired optic neuropathies; this code is specifically for hereditary forms.
• Review documentation for specific type of hereditary optic atrophy (e.g., Leber's, dominant) if known, as more specific codes may exist within the H47.2x category.
• Code any associated visual disturbances or blindness separately if applicable and documented.
