Poisoning by iminostilbenes, assault, sequela

This code signifies a long-term or residual effect resulting from a deliberate act of poisoning with iminostilbene-derived medications. These substances are primarily anticonvulsants and mood stabilizers, and the sequela indicates that the patient is experiencing lasting health problems directly attributable to the past poisoning event.

Apply this code when documenting a patient presenting with chronic or permanent conditions (e.g., neurological damage, organ dysfunction) that are a direct consequence of a previous iminostilbene poisoning that was determined to be an assault. This code is used after the acute phase of the poisoning has resolved, to describe the ongoing health issues.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., specific neurological disorder).
• Ensure documentation clearly links the current condition to a past iminostilbene poisoning and specifies the intent as assault.
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code with the 7th character for initial or subsequent encounter.
