Poisoning by oth drugs acting on muscles, assault, subs

This code signifies a subsequent encounter for a patient who has experienced poisoning due to a drug primarily affecting muscle function, where the poisoning was intentionally inflicted by another person (assault). It indicates that the patient is receiving ongoing care related to the initial toxic exposure.

Use this code when documenting follow-up visits, readmissions, or continued treatment for a patient previously diagnosed with poisoning from a muscle-acting drug due to an assault. This applies to scenarios where the acute phase of the poisoning has passed, but the patient still requires medical attention for its effects or complications.

• Always pair this code with an external cause code (e.g., Y07.-) to fully describe the circumstances of the assault.
• Ensure the "D" seventh character is appropriate for a subsequent encounter; use "A" for initial and "S" for sequela.
• Verify the specific drug involved and its primary action to confirm it falls under "drugs acting on muscles."
