H10.31

What This Code Means

This code describes sudden inflammation of the clear membrane covering the white part of the right eye, with the specific cause not identified. It's commonly known as pink eye and typically develops quickly with redness, irritation, and discharge.

Coding Tips

• •Verify documentation specifies the right eye; if both eyes are affected, use separate codes for each eye (H10.31 for right, H10.32 for left, or H10.33 for bilateral)
• •Use this code only when the provider documents acute conjunctivitis without identifying a specific cause; if a cause is documented (bacterial, viral, allergic, etc.), use the more specific code instead
