Squamous blepharitis right lower eyelid

This code describes an inflammatory condition of the right lower eyelid margin, characterized by the presence of scales or crusts. It indicates a specific type of blepharitis, differentiating it from ulcerative or parasitic forms. The inflammation primarily affects the skin and lash follicles of the eyelid.

Use this code when documentation clearly specifies squamous blepharitis affecting the right lower eyelid. This diagnosis is typically made upon visual inspection during an ophthalmological or optometric examination. Supporting documentation should include findings such as scaling, crusting, or erythema localized to the right lower eyelid margin.

• Ensure the documentation specifies "squamous" blepharitis; if not, a more general blepharitis code may be appropriate.
• Verify the laterality and specific eyelid (upper/lower) are clearly documented to select the most precise code.
• Do not confuse with ulcerative blepharitis (H01.01-) or parasitic blepharitis (H01.03-), which have distinct clinical presentations and coding.
