Conjunctival concretions, left eye

This code describes the presence of small, hard, yellowish-white deposits, often calcified, embedded in the conjunctiva of the left eye. These concretions, also known as lithiasis or concretio conjunctivae, are typically benign and can be asymptomatic or cause irritation.

Apply this code when documentation specifically indicates conjunctival concretions are present in the left eye. This diagnosis is often made during a routine eye examination or when a patient presents with foreign body sensation or irritation. Supporting documentation should clearly specify the affected eye.

• Ensure the laterality is accurately documented as "left eye" to support this specific code.
• Do not confuse this with foreign body sensation without actual embedded concretions.
• If concretions are bilateral, a separate code for the right eye (H11.121) and an unspecified code (H11.123) would be used, or a bilateral code if available for the condition.
