Hypopyon, unspecified eye

This code describes the presence of hypopyon, which is an accumulation of white blood cells (pus) in the anterior chamber of the eye, indicating severe inflammation or infection. It specifically applies when the affected eye is not documented or cannot be determined.

Use this code when the medical record clearly states the presence of hypopyon but does not specify whether it affects the right, left, or both eyes. This often occurs in initial assessments or when laterality is not explicitly documented.

• Always strive for laterality specificity (e.g., H20.051 for right eye, H20.052 for left eye, H20.053 for bilateral) if documented.
• This code should be used as a last resort when laterality is truly unknown or unspecifiable.
• Code an underlying cause of the hypopyon, such as endophthalmitis or severe uveitis, if documented.
