ICD-10 Code H15.83 – Staphyloma posticum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.83 – Staphyloma posticum
What it is
H15.83 identifies a posterior staphyloma, which is an outward bulging of the back wall of the eyeball. It is typically associated with high myopia and structural thinning of the sclera.
Clinical signs
Clinical features vary; refer to documentation. Common findings include a posterior scleral outpouching on eye examination or imaging, often with myopic retinal changes and reduced visual acuity.
When to use this code
Use H15.83 when the provider documents staphyloma posticum or posterior staphyloma as the diagnosed condition. It may also fit when imaging or ophthalmology notes clearly confirm the deformity and link it to the encounter. Code the documented eye disorder, not just high myopia, unless the staphyloma is specifically stated.
Do not use for
Do not use this code for unspecified globe abnormalities or myopia alone. If the record does not clearly identify a posterior staphyloma, check documentation.
Coding tip
Look for the exact term “staphyloma posticum” or “posterior staphyloma” in the assessment or imaging report before assigning H15.83.
