Toxic maculopathy, right eye

This code signifies damage to the macula of the right eye caused by exposure to a toxic substance. This maculopathy can lead to impaired central vision, affecting tasks like reading and recognizing faces. The toxic agent could be a medication, environmental chemical, or other harmful substance.

Apply this code when documentation clearly indicates maculopathy in the right eye resulting from a toxic etiology. This typically involves a history of exposure to a known or suspected toxic agent and ophthalmological findings consistent with macular damage. Supporting documentation includes physician notes detailing the toxic exposure, visual acuity changes, and funduscopic examination findings.

• Ensure the documentation specifies "right eye" to support laterality.
• Always code the underlying toxic agent first, if known and applicable, using an external cause code (T36-T65) to fully describe the etiology.
• Differentiate from other forms of maculopathy (e.g., age-related, degenerative) by confirming the toxic origin.
