Arcus senilis, left eye

This code describes arcus senilis, a benign, age-related corneal degeneration characterized by a white, gray, or bluish ring or arc around the iris. It results from lipid deposition in the peripheral cornea, typically bilateral, and does not usually affect vision.

Use this code when documentation specifies arcus senilis affecting the left eye. This condition is commonly observed during routine ophthalmic examinations in older adults. Ensure the medical record clearly indicates the laterality of the arcus.

• Confirm laterality; separate codes exist for right eye, bilateral, and unspecified.
• Do not confuse with arcus juvenilis, which occurs in younger individuals and may indicate hyperlipidemia.
• This is a diagnosis code; no procedure code is associated with its identification.
