ICD-10 Code H44.411 – Flat anterior chamber hypotony of right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.411 – Flat anterior chamber hypotony of right eye
What it is
H44.411 identifies a flat anterior chamber with hypotony in the right eye. It means the front chamber of the eye is abnormally shallow or collapsed, usually because intraocular pressure is too low.
Clinical signs
Typical findings include a shallow or flat anterior chamber on examination and evidence of ocular hypotony. Clinical features vary; refer to documentation for the exact cause and associated eye findings.
When to use this code
Use this code when the record specifically documents flat anterior chamber hypotony in the right eye. It is appropriate for postoperative, traumatic, or other documented hypotony cases when the right eye is identified. Check documentation if laterality or the cause is unclear.
Do not use for
Do not use this code for hypotony without a flat anterior chamber, or for left eye or bilateral involvement. If the note does not clearly identify the right eye, check documentation.
Coding tip
Confirm laterality and the exact wording of the eye exam before assigning H44.411.
