Hypotony of eye due to other ocular disorders, right eye

This code signifies abnormally low intraocular pressure (IOP) in the right eye, which is a consequence of another underlying eye condition. This hypotony is not due to surgical intervention, trauma, or inflammation, but rather a secondary effect of a different ocular pathology.

Apply this code when documentation clearly indicates hypotony of the right eye caused by a pre-existing or co-occurring ocular disorder, such as retinal detachment, chronic glaucoma with extensive damage, or certain degenerative eye diseases. Ensure the physician explicitly links the hypotony to a specific "other ocular disorder" in the right eye.

• Always code the underlying "other ocular disorder" first, as it is the primary cause of the hypotony.
• Distinguish this from hypotony due to surgical complications (H44.41-), trauma (H44.42-), or inflammation (H44.40-).
• Verify laterality; this code is specific to the right eye. Use H44.432 for the left eye and H44.433 for bilateral involvement.
