Pseudomembranous conjunctivitis, left eye

This code signifies an inflammatory condition of the conjunctiva characterized by the formation of a false membrane on the surface of the eye, specifically affecting the left eye. This pseudomembrane is composed of fibrin, inflammatory cells, and necrotic epithelium, which can be peeled away.

Apply this code when documentation explicitly states "pseudomembranous conjunctivitis" and specifies the left eye as the affected anatomical site. This condition is often associated with severe bacterial or viral infections, such as diphtheria or adenovirus.

• Ensure the documentation clearly distinguishes between pseudomembranous and membranous conjunctivitis, as they are distinct conditions.
• Always verify the laterality (left eye) is explicitly stated in the clinical notes.
• Code any underlying infectious agent if identified and documented, using an additional code.
