ICD-10 Code H04.521 – Eversion of right lacrimal punctum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H04.521 – Eversion of right lacrimal punctum
What it is
H04.521 identifies outward turning of the right lacrimal punctum, the small opening that drains tears from the eye. This malposition can interfere with normal tear drainage.
Clinical signs
Typical findings include punctal eversion on exam and symptoms related to poor tear drainage, such as tearing or ocular irritation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents eversion of the right lacrimal punctum. It may be appropriate for ophthalmology visits, preoperative assessment, or follow-up when the abnormal punctal position is the condition being addressed.
Code it only when the right side is clearly identified. If the note describes punctal malposition without laterality, check documentation before assigning H04.521.
Do not use for
Do not use this code for left-sided or bilateral punctal eversion, or for general tearing without documented punctal eversion. Check documentation if the finding is described differently.
Coding tip
Verify laterality in the ophthalmology note, because punctal disorders are coded by side and the wrong laterality changes the code.
