ICD-10 Code H15.831 – Staphyloma posticum, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.831 – Staphyloma posticum, right eye
What it is
H15.831 identifies a posterior staphyloma in the right eye, meaning an outward bulging of the back wall of the globe. It is usually associated with elongation or thinning of the eye wall.
Clinical signs
Findings may include a posterior outpouching seen on eye examination or imaging, often in the setting of high myopia. Clinical features vary; refer to documentation.
When to use this code
Use H15.831 when the provider documents staphyloma posticum limited to the right eye. Code it for confirmed posterior staphyloma on exam, imaging, or specialist assessment. Check documentation if laterality is unclear or if the note only mentions myopia without staphyloma.
Do not use for
Do not use this code for unspecified eye laterality or for other types of staphyloma. Do not assign it when the record only describes refractive error or general retinal changes.
Coding tip
Verify that the documentation states “right eye” and “staphyloma posticum” before assigning H15.831.
