ICD-10 Code H15.04 – Scleritis with corneal involvement (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.04 – Scleritis with corneal involvement
What it is
H15.04 identifies scleritis that extends to the cornea. Use it when the chart documents inflammation of the sclera with corneal involvement, not simple redness or nonspecific eye pain.
Clinical signs
Typical findings include deep ocular pain, scleral redness, and signs of corneal involvement such as adjacent corneal inflammation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the clinician specifically documents scleritis with corneal involvement, or an equivalent diagnosis in the assessment. It is appropriate when the record shows both scleral inflammation and corneal extension, and you can support that wording from the note.
If the documentation only states scleritis without corneal involvement, code the more general condition instead. Check documentation when the corneal component is unclear, suspected, or mentioned only in imaging or referral notes.
Do not use for
Do not use H15.04 for isolated scleritis, episcleritis, or nonspecific conjunctival irritation. Do not assign it when corneal disease is present without documented scleritis.
Coding tip
Match the code to explicit provider wording; if corneal involvement is not stated, query or code the documented scleritis only.
