ICD-10 Code H44.432 – Hypotony of eye due to other ocular disorders, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.432 – Hypotony of eye due to other ocular disorders, left eye
What it is
This code identifies low intraocular pressure in the left eye caused by another eye disorder. It is used when the hypotony is a consequence of an underlying ocular condition, not a primary finding.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include a persistently low eye pressure and signs of the underlying disorder affecting the left eye.
When to use this code
Use H44.432 when the record states hypotony of the left eye and links it to another ocular disorder. The documentation should support both the low-pressure condition and its cause. If the cause is not specified, check documentation before assigning the code.
Do not use for
Do not use this code for hypotony of the eye without a documented ocular cause. It is also incorrect when the condition involves the right eye, both eyes, or a non-ocular cause.
Coding tip
Verify laterality and the documented underlying eye disorder before coding H44.432.
