Vascular abnormalities of conjunctiva, unspecified eye

This code signifies the presence of an abnormal blood vessel condition affecting the conjunctiva, the clear membrane lining the eyelid and covering the white part of the eye. This can include conditions like telangiectasias, hemangiomas, or other malformations of the conjunctival vasculature. The specific type of vascular abnormality and the affected eye are not specified.

Use this code when documentation indicates a vascular abnormality of the conjunctiva but does not specify the exact nature of the abnormality or laterality. This is appropriate when the physician's notes describe a conjunctival vascular lesion without further diagnostic detail, or when the laterality (right, left, or bilateral) is not documented.

• Avoid using this code if the specific type of vascular abnormality (e.g., conjunctival telangiectasia) is documented; instead, use a more specific code from the H11.4- series.
• Do not use this code if laterality is specified; refer to H11.411, H11.412, or H11.413 for right, left, or bilateral involvement, respectively.
• Ensure the documentation clearly states the abnormality is of the conjunctiva, not other ocular structures.
