Ulcerative blepharitis right eye, unspecified eyelid

This code signifies an inflammatory condition of the right eyelid margin characterized by ulceration, typically due to bacterial infection (e.g., staphylococcal). It involves the base of the eyelashes and can lead to crusting, redness, and discomfort. The "unspecified eyelid" component indicates that the specific upper or lower eyelid affected is not documented.

Use this code when documentation clearly states ulcerative blepharitis affecting the right eye, but does not specify whether it's the upper or lower eyelid. This diagnosis is often made during an ophthalmological examination based on visual inspection and patient symptoms. Supporting documentation would include notes detailing ulceration, inflammation, and laterality.

• Ensure documentation specifies "ulcerative" blepharitis; simple blepharitis (H01.00-) or squamous blepharitis (H01.02-) are distinct.
• Verify laterality (right eye) is explicitly stated. If left eye, use H01.014; if bilateral, use H01.015.
• If the specific eyelid (upper or lower) is documented, use a more precise code from the H01.01- subcategory (e.g., H01.011 for right upper eyelid).
