ICD-10 Code H15.039 – Posterior scleritis, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.039 – Posterior scleritis, unspecified eye
What it is
Use this code for inflammation of the posterior part of the sclera in an unspecified eye. It identifies posterior scleritis when the affected eye is not documented.
Clinical signs
Findings may include deep eye pain, decreased vision, and signs of posterior scleral inflammation on exam or imaging. Clinical features vary; refer to documentation.
When to use this code
Use H15.039 when the provider documents posterior scleritis and does not specify right or left eye. It is also appropriate when the record confirms posterior scleritis but laterality is unavailable. Code only when the diagnosis is clearly stated.
Do not use for
Do not use this code for anterior scleritis, nonspecific eye pain, or suspected disease without confirmation. If the eye is documented, choose the laterality-specific code instead.
Coding tip
Check the note for laterality and whether the diagnosis is confirmed, because H15.039 is for unspecified eye only.
