ICD-10 Code H44.441 – Primary hypotony of right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.441 – Primary hypotony of right eye
What it is
H44.441 identifies abnormally low intraocular pressure in the right eye when it is documented as primary, meaning it is not coded as a complication or secondary to another eye disorder.
Clinical signs
Clinical features may include a soft eye on exam, reduced intraocular pressure, and possible visual disturbance. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents primary hypotony affecting only the right eye. It fits cases where the low pressure is the diagnosis itself and no separate cause is stated. If the record identifies a postoperative or traumatic cause, check documentation and code the documented condition instead.
Do not use for
Do not use H44.441 for hypotony that is clearly secondary to surgery, trauma, or another eye disease. Check documentation if the note describes bilateral involvement or a different eye.
Coding tip
Confirm laterality and whether the hypotony is primary before assigning H44.441.
