ICD-10 Code H15.05 – Scleromalacia perforans (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.05 – Scleromalacia perforans
What it is
Scleromalacia perforans is a rare, severe form of necrotizing scleritis with thinning of the sclera, often with little pain or redness. It can lead to visible uveal show through the weakened eye wall.
Clinical signs
You may see focal scleral thinning, bluish discoloration, and areas of avascular necrosis. Clinical features vary; refer to documentation, but the condition is often associated with minimal inflammation compared with other scleritis types.
When to use this code
Use this code when the record specifically documents scleromalacia perforans or clearly identifies this necrotizing scleral thinning. It is appropriate for ophthalmology notes describing the condition as a distinct diagnosis, not just generic scleral thinning. Check documentation if the chart only says scleritis or scleral ulceration.
Do not use for
Do not use it for nonspecific eye redness, simple scleral thinning, or other forms of scleritis without documentation of scleromalacia perforans. Do not assign it when the diagnosis is uncertain; check documentation.
Coding tip
Code the exact ophthalmic diagnosis stated by the specialist, because “scleritis” alone is not enough for H15.05.
