H10.32

What This Code Means

This code describes sudden inflammation of the clear membrane covering the white part of the left eye and inner eyelid, with the specific cause not identified. It typically presents with redness, irritation, and discharge.

Coding Tips

• •Use this code only when the acute conjunctivitis is unspecified (cause unknown); if a specific cause is identified (bacterial, viral, allergic), use the more specific code instead
• •The code is laterality-specific for the left eye; ensure you have documented which eye is affected and use H10.31 for right eye or H10.33 for bilateral cases
