Posterior scleritis, left eye

This code signifies inflammation of the posterior sclera, the tough, white outer layer of the eye, specifically affecting the left eye. This condition can lead to pain, vision changes, and, if severe, retinal detachment or choroidal effusions.

Apply this code when documentation clearly indicates posterior scleritis diagnosed in the left eye. Supporting clinical notes should detail symptoms such as deep eye pain, vision loss, or signs observed during ophthalmoscopy, such as choroidal folds or serous retinal detachment.

• Ensure laterality is precisely documented; differentiate from right eye (H15.031) or bilateral (H15.033).
• Code any associated underlying systemic conditions (e.g., autoimmune diseases) as primary diagnoses if they are the cause of the scleritis.
• Distinguish from anterior scleritis (H15.02-) which presents with different clinical features and anatomical involvement.
