Ulcerative blepharitis right eye, upper and lower eyelids

This code signifies an inflammatory condition of the eyelid margins, specifically affecting the right eye's upper and lower lids, characterized by ulceration. It involves chronic inflammation of the eyelash follicles and meibomian glands, leading to crusting, scaling, and open sores along the lid margin.

Use this code when documentation specifies ulcerative blepharitis impacting both the upper and lower eyelids of the right eye. This diagnosis is typically supported by ophthalmological examination findings detailing ulcerations, inflammation, and crusting along the lid margins. It's appropriate for both initial encounters and subsequent care for this specific condition.

• Ensure documentation clearly specifies "ulcerative" blepharitis, as other forms exist (e.g., squamous, seborrheic).
• Verify laterality (right eye) and affected eyelids (upper and lower) are explicitly stated to support this specific code.
• Distinguish from H01.01B (left eye) or H01.01C (bilateral) when only the right eye is affected.
