Vitreous abscess (chronic), left eye

This code describes a chronic infection within the vitreous humor of the left eye, characterized by the presence of pus. This condition can lead to significant vision impairment due to inflammation and opacification of the normally clear gel-like substance filling the eye. It is a persistent or long-standing inflammatory process.

Use this code when documentation clearly indicates a chronic vitreous abscess affecting the left eye. Supporting documentation should include ophthalmological examination findings such as vitreous opacities, inflammatory cells, and evidence of infection, along with a physician's diagnosis of chronicity. This code is appropriate for ongoing management or follow-up of a long-term vitreous infection.

• Ensure the documentation specifies "chronic" to differentiate from acute vitreous abscesses.
• Verify laterality; this code is specific to the left eye.
• Code any underlying systemic infections or conditions contributing to the abscess as additional diagnoses.
