Glaucoma secondary to oth eye disorders, bi, stage unsp

This code signifies elevated intraocular pressure and optic nerve damage in both eyes, resulting from another underlying ocular condition. It represents a form of secondary glaucoma where the specific stage of the disease has not been documented.

Apply this code when documentation clearly indicates that glaucoma in both eyes is a direct consequence of another eye disorder (e.g., uveitis, intraocular hemorrhage, retinal detachment) and the physician has not specified the stage of the glaucoma. This code requires bilateral involvement.

• Ensure documentation explicitly states "bilateral" involvement.
• Always code the underlying eye disorder first, followed by this glaucoma code.
• If the stage of glaucoma is documented (e.g., mild, moderate, severe, indeterminate), use the more specific code from the H40.53 series.
