Residual stage of angle-closure glaucoma, right eye

This code signifies the permanent damage or sequelae resulting from a past episode of angle-closure glaucoma affecting the right eye. It indicates that the acute phase of the disease has resolved, but residual effects, such as optic nerve damage or visual field loss, persist.

Use this code when documentation explicitly states "residual stage" or "sequelae" of angle-closure glaucoma in the right eye. This applies to patients who have undergone treatment for acute angle-closure glaucoma and now present with stable, non-progressive damage attributable to the prior event.

• Ensure documentation clearly specifies "residual stage" and laterality (right eye).
• Do not use for active or acute angle-closure glaucoma; those conditions have different codes.
• Consider additional codes for specific residual manifestations, such as visual field defects (e.g., H53.4x) or blindness (e.g., H54.x), if documented.
