Rosacea conjunctivitis, unspecified eye

This code identifies an inflammatory condition affecting the conjunctiva, characterized by symptoms such as redness, irritation, and foreign body sensation, specifically linked to rosacea. It represents a manifestation of rosacea impacting the ocular surface, without specifying which eye is affected.

Apply this code when documentation confirms a diagnosis of rosacea conjunctivitis but does not specify laterality (e.g., "rosacea conjunctivitis" without "right," "left," or "bilateral"). This code is appropriate when the physician's notes indicate ocular involvement secondary to rosacea, such as chronic blepharitis, telangiectasias of the lid margin, or recurrent chalazia, all attributed to rosacea.

• Avoid using this code if laterality is documented; instead, choose the appropriate H10.821 (right eye), H10.822 (left eye), or H10.823 (bilateral) code.
• Ensure the medical record clearly links the conjunctivitis to rosacea, rather than other causes of conjunctivitis.
• Consider co-reporting with a code for the underlying rosacea (e.g., L71.9 for rosacea, unspecified) if not already documented as a primary diagnosis.
