Toxic effect of mercury and its compounds, acc, sequela

This code signifies the long-term or residual effects resulting from an accidental exposure to mercury or its compounds. These sequelae can manifest as chronic neurological, renal, or gastrointestinal issues that persist after the acute phase of poisoning has resolved.

Apply this code when documenting conditions that are a direct consequence of a past, unintentional mercury poisoning event. This includes chronic kidney disease, peripheral neuropathy, or cognitive impairment definitively linked to a prior accidental mercury exposure.

• Always use in conjunction with a code describing the specific sequela (e.g., a code for chronic kidney disease).
• Ensure documentation clearly links the current condition to a past accidental mercury exposure.
• Do not use for acute mercury poisoning; this code is exclusively for residual effects.
