Degenerative myopia with foveoschisis, left eye

This code describes a specific type of high myopia where the retina, particularly the fovea, begins to split or detach due to degenerative changes. This condition primarily affects the left eye and can lead to significant vision impairment. It is a progressive disorder often associated with severe axial elongation of the eyeball.

Use this code when documentation explicitly states degenerative myopia with foveoschisis affecting the left eye. This diagnosis is typically made by an ophthalmologist based on clinical examination, optical coherence tomography (OCT) imaging showing retinal splitting, and a history of high myopia. Ensure the laterality is clearly specified as left eye.

• Differentiate from other forms of myopic maculopathy; foveoschisis is a distinct finding.
• Confirm documentation specifies "degenerative myopia" as opposed to other types of myopia.
• Always verify the affected eye (left, right, or bilateral) to ensure correct laterality coding.
