Horseshoe tear of retina without detachment, left eye

This code signifies a specific type of retinal break, characterized by a U-shaped or horseshoe-shaped tear in the retina of the left eye. Importantly, this tear has not yet progressed to a full retinal detachment, meaning the neurosensory retina remains attached to the retinal pigment epithelium.

This code is appropriate when documentation clearly indicates a horseshoe tear of the retina in the left eye without any associated retinal detachment. This typically occurs during an ophthalmological examination, often following symptoms like flashes or floaters, where fundoscopy or optical coherence tomography (OCT) confirms the tear's presence and the absence of detachment.

• Ensure documentation specifies "without detachment" to differentiate from codes indicating retinal detachment.
• Verify laterality; this code is specific to the left eye.
• Do not confuse with atrophic holes or operculated tears, which have distinct ICD-10-CM codes.
