Simple chronic conjunctivitis, left eye

This code signifies a persistent, non-infectious inflammation of the conjunctiva in the left eye, characterized by symptoms such as redness, irritation, and discharge lasting for an extended period. It represents a mild, long-standing form of conjunctivitis without severe complications or specific infectious agents.

Apply this code when documentation clearly indicates chronic conjunctivitis affecting only the left eye, described as "simple" or non-specific. This is appropriate for conditions like allergic conjunctivitis or irritant conjunctivitis that have become chronic. Supporting documentation should specify the chronicity and laterality.

• Ensure documentation specifies "chronic" and "left eye" to differentiate from acute or bilateral forms.
• Do not use if an underlying infectious agent (e.g., bacterial, viral) is identified; use more specific codes for those conditions.
• Consider codes for allergic conjunctivitis (H10.1-) if an allergen is identified as the cause of the chronic inflammation.
