Degenerative myopia with foveoschisis, bilateral

This code signifies a severe form of myopia characterized by progressive thinning and stretching of the retina, specifically affecting both eyes, and complicated by foveoschisis. Foveoschisis involves the splitting of retinal layers in the fovea, the central part of the macula responsible for sharp, detailed vision. This condition can lead to significant and irreversible vision loss.

Apply this code when documentation confirms a diagnosis of degenerative myopia affecting both eyes, with the specific complication of foveoschisis. This typically occurs in patients with high myopia (often greater than -6.00 diopters) and characteristic fundoscopic findings or optical coherence tomography (OCT) evidence of retinal layer splitting in the fovea.

• Ensure the documentation explicitly states "bilateral" involvement and confirms the presence of "foveoschisis" in the context of degenerative myopia.
• Differentiate from other myopic maculopathies, such as myopic choroidal neovascularization or myopic traction maculopathy without schisis.
• Sequence this code as a primary diagnosis when it is the main reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting treatment or prognosis.
