Conjunctival concretions, unspecified eye

This code describes the presence of small, hard, yellowish-white deposits, often referred to as concretions or lithiasis, located within the conjunctiva of an unspecified eye. These deposits are typically composed of degenerated epithelial cells and mucus, which can become calcified over time. While often asymptomatic, they can cause foreign body sensation, irritation, or corneal abrasion if they protrude.

Use this code when documentation indicates conjunctival concretions are present, but the specific eye (right or left) is not specified. This code is appropriate when the provider notes the presence of these deposits without further detail on laterality. Supporting documentation would include clinical notes describing "conjunctival concretions" or "lithiasis" without specifying the affected eye.

• Avoid using this code if the laterality (right or left eye) is clearly documented; instead, choose the more specific H11.121 or H11.122.
• This code is for the presence of concretions themselves, not for symptoms they may cause (e.g., foreign body sensation, irritation).
• Ensure the documentation explicitly states "unspecified eye" or lacks laterality information to justify using this code.
