Panophthalmitis (acute), left eye

This code signifies a severe, acute inflammation affecting all structures of the left eye, including the sclera, choroid, retina, and vitreous. It represents a widespread infection or inflammatory process within the entire eyeball.

Apply this code when documentation explicitly states acute panophthalmitis affecting the left eye. This diagnosis is typically supported by findings of diffuse inflammation, pain, vision loss, and potentially purulent discharge involving all ocular tissues.

• Ensure the documentation specifies "acute" and clearly identifies the "left eye" to support this laterality.
• Distinguish from endophthalmitis (H44.00-H44.009), which is inflammation of the intraocular fluids and membranes, not necessarily all structures.
• Code any underlying cause, such as a bacterial or fungal infection, as an additional diagnosis.
