Congenital malformation of vitreous humor

This code signifies a birth defect affecting the vitreous humor, the clear gel that fills the space between the lens and the retina of the eye. These malformations can include conditions like persistent hyperplastic primary vitreous (PHPV), vitreous cysts, or other structural anomalies present at birth. Such conditions can impair vision and may lead to other ocular complications.

Apply this code when documentation explicitly states a congenital anomaly of the vitreous humor. This typically involves findings from an ophthalmological examination, often including imaging like ultrasound, confirming a structural defect of the vitreous present from birth. It is appropriate for initial diagnoses and subsequent encounters related to the management of this specific congenital condition.

• Ensure documentation specifies "congenital" to differentiate from acquired vitreous conditions.
• Do not use for acquired vitreous opacities or detachments; these have distinct ICD-10-CM codes.
• Code any associated ocular malformations or visual impairments separately, if documented.
