Arcus senilis, bilateral

This code describes arcus senilis affecting both eyes. Arcus senilis is a benign, age-related corneal degeneration characterized by a white, gray, or bluish ring or arc around the limbus due to lipid deposits in the peripheral cornea. It typically does not affect vision.

Use this code when documentation explicitly states "arcus senilis, bilateral" or "corneal arcus, bilateral." This condition is commonly noted during routine ophthalmological examinations in older adults. Documentation should confirm the presence of the arcus in both eyes.

• Differentiate from arcus juvenilis, which occurs in younger individuals and may indicate hyperlipidemia.
• Ensure laterality is clearly documented (bilateral, right, left) to select the most specific code.
• This is a diagnosis code; no procedure code is typically associated with its identification.
