Poisoning by other drugs acting on muscles, assault, sequela

This code indicates a long-term or residual effect resulting from a deliberate act of poisoning by a substance that affects muscle function, such as a neuromuscular blocker or muscle relaxant. The initial poisoning event was an assault, and the patient is now presenting with ongoing health issues directly attributable to that past event.

Apply this code when documenting a patient's current condition, which is a lasting consequence of a previous poisoning by a muscle-acting drug, where the poisoning was intentionally inflicted by another person. This would be used for follow-up visits or when the sequela is the primary reason for the encounter, long after the acute poisoning has been treated.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., muscle weakness, paralysis).
• Ensure documentation clearly links the current condition to a past poisoning by a muscle-acting drug and specifies the assault intent.
• Do not use this code for the acute poisoning event itself; this is exclusively for the long-term effects.
