Unspecified purulent endophthalmitis, left eye

This code describes an acute inflammatory condition of the internal structures of the left eye, characterized by the presence of pus. It signifies a severe intraocular infection that can lead to significant vision loss if not promptly treated. The "unspecified" nature indicates that the specific causative organism is not documented.

Use this code when documentation clearly indicates purulent endophthalmitis affecting the left eye, but the etiology (e.g., bacterial, fungal) is not specified. This typically occurs in emergency settings or when initial cultures are pending. Supporting documentation includes ophthalmology notes detailing signs of intraocular inflammation, hypopyon, vitritis, and left eye involvement.

• Ensure laterality is accurately documented; this code is specific to the left eye.
• If the causative organism is identified, a more specific code from the H44.0- series should be used (e.g., H44.012 for panophthalmitis, left eye).
• Always sequence this code after any underlying cause of the endophthalmitis, if known and documented (e.g., post-surgical complication, penetrating injury).
