ICD-10 Code H44.433 – Hypotony of eye due to other ocular disorders, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.433 – Hypotony of eye due to other ocular disorders, bilateral
What it is
This code identifies low intraocular pressure in both eyes caused by another eye disorder. It is used when the hypotony is secondary to an underlying ocular condition, not an isolated finding.
Clinical signs
Clinical features may include a soft eye, reduced intraocular pressure on exam, and vision changes. Findings depend on the underlying disorder; refer to documentation for the specific cause.
When to use this code
Use this code when the record states bilateral ocular hypotony due to another eye disease, such as postoperative or inflammatory eye pathology. The documentation should link the low pressure to the underlying ocular disorder. If the cause is not specified, check documentation before coding.
Do not use for
Do not use this code for hypotony without a documented ocular cause or when only one eye is affected. It is also not appropriate if the record describes a different condition with no confirmed hypotony.
Coding tip
Verify both laterality and the documented underlying eye disorder before assigning H44.433.
