Arcus senilis, right eye

This code describes arcus senilis, a benign, age-related corneal degeneration characterized by a white, gray, or bluish opaque ring in the periphery of the cornea. This specific code indicates the condition is present in the right eye. It results from lipid deposits in the corneal stroma and Bowman's membrane.

Use this code when documentation specifies arcus senilis affecting the patient's right eye. This is a common finding during routine ophthalmic examinations in older adults. Supporting documentation includes ophthalmologist notes detailing the presence and laterality of the corneal ring.

• Ensure laterality is clearly documented (right, left, or bilateral) to select the most specific code.
• Do not confuse with arcus juvenilis, which occurs in younger individuals and may indicate hyperlipidemia.
• This is typically a secondary diagnosis unless it is the primary reason for the encounter (e.g., patient presenting for evaluation of the corneal ring).
