Poisoning by skeletal muscle relaxants, accidental, subs

This code signifies an accidental or unintentional poisoning specifically due to skeletal muscle relaxants, also known as neuromuscular blocking agents. It indicates that the patient is in the "subsequent encounter" phase of care, meaning they are receiving follow-up treatment for the initial poisoning event. This category of drugs affects muscle function and can be dangerous if misused or taken accidentally.

Use this code when documenting follow-up care for a patient who has experienced an accidental overdose or exposure to a skeletal muscle relaxant. This would include scenarios where the patient is being monitored for residual effects, undergoing rehabilitation, or receiving ongoing treatment related to the initial poisoning. It applies after the initial acute phase of treatment has concluded.

• Always use in conjunction with an external cause code (V00-Y99) to specify the circumstances of the poisoning.
• Ensure the "D" seventh character is appropriate for a subsequent encounter; "A" is for initial, "S" for sequela.
• Verify the specific drug involved is a skeletal muscle relaxant/neuromuscular blocking agent to ensure accurate code selection.
