Poisoning by smooth muscle relaxants

This code signifies an adverse reaction or overdose due to medications classified as smooth muscle relaxants. This includes both accidental and intentional poisonings, leading to various systemic effects depending on the specific agent and dosage.

Use this code when documentation clearly indicates a patient's condition is a direct result of poisoning by a smooth muscle relaxant. This applies to scenarios such as an overdose of antispasmodics, bronchodilators, or uterine relaxants. Supporting documentation should specify the substance involved and the nature of the poisoning (e.g., accidental, intentional).

• Always code the manifestation of the poisoning first, if applicable, followed by this code.
• Distinguish between poisoning (adverse effect due to overdose or wrong substance) and adverse effect in therapeutic use (E-code required).
• Ensure the documentation specifies a "smooth muscle relaxant" to differentiate from other drug classes.
