Vitreous abscess (chronic), unspecified eye

This code represents a chronic infection within the vitreous humor of the eye, characterized by the formation of an abscess. This condition involves the accumulation of pus and inflammatory cells in the gel-like substance that fills the posterior segment of the eye, leading to potential vision impairment.

Use this code when documentation clearly indicates a diagnosis of a chronic vitreous abscess without specifying laterality. This typically occurs in cases of persistent intraocular infection where the exact eye affected is not recorded. Supporting documentation would include ophthalmological exam findings, imaging reports, and physician notes confirming the chronic nature and presence of an abscess.

• Ensure the documentation specifies "chronic" to differentiate from acute vitreous abscesses.
• Avoid using this code if laterality (right or left eye) is documented; instead, select the more specific code.
• Look for associated conditions like endophthalmitis or penetrating eye injuries that may be the underlying cause and code them accordingly.
