ICD-10 Code H44.431 – Hypotony of eye due to other ocular disorders, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.431 – Hypotony of eye due to other ocular disorders, right eye
What it is
H44.431 identifies low intraocular pressure in the right eye caused by another ocular disorder. Use it when the chart links hypotony to an eye condition, not to surgery or trauma.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include a documented low intraocular pressure and signs of the underlying eye disorder affecting the right eye.
When to use this code
Use this code when the provider documents hypotony of the right eye due to a specific ocular disease, such as inflammation or another intraocular condition. The cause should be stated or clearly supported in the record. If the note does not identify the cause, check documentation before coding.
Do not use for
Do not use this code for hypotony after surgery or from eye trauma. If the record describes left eye or unspecified eye hypotony, choose the matching laterality code.
Coding tip
Always confirm the underlying ocular disorder and laterality, because H44.431 is specific to the right eye.
