Lattice degeneration of retina, right eye

This code represents a specific type of peripheral retinal degeneration characterized by a network of thin, red lines that resemble a lattice, often associated with atrophic holes or tears. It primarily affects the right eye and increases the risk of retinal detachment due to its predisposition to retinal breaks.

Use this code when documentation explicitly states "lattice degeneration of the retina" affecting the right eye. This diagnosis is typically made during a dilated fundus examination by an ophthalmologist. Supporting documentation should include findings such as characteristic lattice lesions, atrophic holes, or pigmentary changes in the right eye.

• Always specify laterality (right, left, or bilateral) when documenting and coding retinal conditions.
• Do not confuse with other types of retinal degeneration, such as paving-stone degeneration or retinoschisis.
• If a retinal detachment or tear is also present, code the detachment/tear first, followed by the lattice degeneration as an associated condition.
