Toxic effect of manganese and its compounds, acc, sequela

This code signifies the long-term or residual effects resulting from an accidental exposure to manganese or its compounds. These sequelae can manifest as neurological impairments, such as parkinsonism-like symptoms, cognitive deficits, or psychiatric disturbances, occurring after the acute phase of toxicity has passed.

Apply this code when documenting chronic conditions or permanent damage directly attributable to a past, unintentional manganese poisoning. This is appropriate for patients presenting with persistent symptoms years after an acute exposure, or when a diagnosis of manganism is established as a consequence of accidental intake or inhalation.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., G21.8 for other secondary parkinsonism).
• Ensure documentation clearly links the current condition to a past accidental manganese exposure.
• Do not use for acute toxicity or intentional poisoning; specific codes exist for those scenarios.
