Retinal detachment with giant retinal tear, right eye

This code signifies a rhegmatogenous retinal detachment in the right eye that is specifically caused by a giant retinal tear. A giant retinal tear is a full-thickness retinal break extending 90 degrees or more around the circumference of the retina. This condition leads to separation of the neurosensory retina from the underlying retinal pigment epithelium.

Apply this code when documentation clearly indicates a retinal detachment in the right eye, and the etiology is identified as a giant retinal tear. This typically occurs following trauma or spontaneously. Supporting documentation should include ophthalmological examination findings, such as indirect ophthalmoscopy or optical coherence tomography (OCT) reports, confirming both the detachment and the presence and laterality of the giant retinal tear.

• Ensure the documentation specifies "giant retinal tear" and not just a large or multiple retinal tears, as this is a distinct clinical entity.
• Verify laterality; this code is specific to the right eye. Use H33.032 for the left eye and H33.033 for bilateral involvement.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, especially for surgical repair.
