Toxic maculopathy, unspecified eye

This code describes damage to the macula, the central part of the retina responsible for sharp, detailed vision, caused by exposure to toxic substances. This maculopathy is not specified as to the laterality of the affected eye. The toxic agent could be a medication, chemical, or other environmental toxin.

Use this code when documentation indicates maculopathy resulting from a toxic exposure, and the specific eye affected (right or left) is not documented. This diagnosis is supported by a history of exposure to a known or suspected toxic agent and clinical findings of macular damage.

• Always seek to clarify laterality (right, left, or bilateral) if not specified in the documentation to use a more specific code.
• Code the specific toxic agent (e.g., adverse effect of drug, poisoning) as an additional diagnosis, if known and documented.
• Do not use this code if the maculopathy is due to a hereditary condition, age-related degeneration, or other non-toxic etiologies.
