Corneal deposits in metabolic disorders, unspecified eye

This code signifies the presence of abnormal deposits on the cornea of an unspecified eye, which are directly attributable to an underlying systemic metabolic disorder. These deposits can affect corneal clarity and vision, and their composition varies depending on the specific metabolic disturbance.

Use this code when documentation clearly links corneal deposits to a metabolic disorder, but the specific eye affected is not specified. This diagnosis is appropriate when the ophthalmologist identifies corneal changes and the patient has a known or suspected systemic metabolic condition, such as cystinosis, mucopolysaccharidoses, or lipid storage disorders.

• Always code the underlying metabolic disorder first, as it is the primary etiology.
• Avoid using this code if the specific eye (right or left) is documented; instead, use the more specific H18.031 or H18.032.
• Ensure the medical record explicitly states the connection between the corneal deposits and a metabolic disorder; otherwise, consider codes for other types of corneal deposits.
