Conjunctival concretions, bilateral

This code describes the presence of small, hard, yellowish-white deposits, often composed of epithelial cells and inspissated mucus, located within the conjunctiva of both eyes. These concretions, also known as lithiasis or calculi, are typically benign and often asymptomatic but can cause irritation.

Apply this code when documentation explicitly states the presence of conjunctival concretions affecting both eyes. This is commonly found during routine eye examinations or when a patient presents with foreign body sensation, irritation, or discomfort attributed to these deposits in both eyes.

• Ensure the documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Do not confuse with foreign body sensation without actual concretions; a distinct diagnosis of concretions must be present.
• Consider coding any associated symptoms, such as foreign body sensation (e.g., H57.1), if documented and clinically relevant.
