Hypopyon, left eye

This code indicates the presence of hypopyon, which is an accumulation of pus or inflammatory cells in the anterior chamber of the left eye. It is a sign of severe inflammation, often associated with infectious or sterile uveitis, corneal ulcers, or endophthalmitis.

Use this code when documentation clearly states the presence of hypopyon specifically affecting the left eye. This condition is typically diagnosed via slit-lamp examination and is often accompanied by other signs of ocular inflammation.

• Always specify laterality (left, right, or bilateral) when documented.
• Code the underlying cause of the hypopyon (e.g., uveitis, corneal ulcer) first, as the hypopyon is a manifestation of that condition.
• Do not use this code if the documentation only mentions general anterior chamber inflammation without specific mention of pus or inflammatory cells forming a layer.
