Unspecified blepharitis right lower eyelid

This code signifies inflammation of the right lower eyelid margin, characterized by redness, swelling, and irritation, without further specification of the underlying cause or type of blepharitis. It indicates a general diagnosis of blepharitis affecting only the lower lid of the right eye.

Apply this code when the physician's documentation confirms blepharitis affecting the right lower eyelid, but the specific type (e.g., ulcerative, seborrheic, angular) is not identified. This is appropriate when the documentation explicitly states "unspecified blepharitis right lower eyelid" or similar phrasing lacking further detail.

• Ensure the documentation specifies "right lower eyelid" for accurate laterality and location.
• Avoid using this code if the physician provides a more specific diagnosis of blepharitis (e.g., ulcerative, seborrheic); instead, select the more precise code.
• If the blepharitis affects both upper and lower eyelids, or is bilateral, a different code will be required.
