Vitreous membranes and strands, unspecified eye

This code signifies the presence of abnormal fibrous tissue or strands within the vitreous humor of the eye, where the specific eye affected is not documented. These membranes or strands can be congenital or acquired, often resulting from inflammation, hemorrhage, or trauma. They may cause visual disturbances such as floaters or flashes of light.

Use this code when documentation indicates vitreous membranes or strands are present, but the medical record does not specify whether the condition affects the right, left, or both eyes. This is appropriate when the physician notes "vitreous membranes" or "vitreous strands" without laterality.

• Avoid using this code if laterality (right, left, or bilateral) is clearly documented; instead, choose a more specific code from the H43.3 subcategory.
• Ensure the documentation supports the presence of these structures and not other vitreous opacities like syneresis or asteroid hyalosis.
• If the vitreous membranes are secondary to another ocular condition, sequence the underlying condition first if it is the primary reason for the encounter.
