Multiple defects of retina without detachment, unsp eye

This code signifies the presence of several structural abnormalities within the retina, such as lattice degeneration, retinal holes, or tears, that are not associated with a retinal detachment. These defects can predispose an individual to future retinal detachment but currently do not involve separation of the neurosensory retina from the retinal pigment epithelium. The specific eye affected is not documented or is unknown.

Use this code when documentation indicates multiple retinal defects (e.g., multiple areas of lattice degeneration, multiple atrophic holes) without any evidence of retinal detachment. This code is appropriate when the physician's notes specify "unspecified eye" or do not clearly indicate laterality for the multiple defects. Documentation should clearly state the presence of multiple defects and explicitly rule out detachment.

• Do not use this code if a retinal detachment is also present; instead, code the specific type of detachment.
• Ensure documentation specifies "multiple" defects; a single defect would be coded differently.
• Avoid using this code if laterality (right or left eye) is clearly documented; use the more specific H33.331 or H33.332.
