Poisoning by irritant cathartics

This code signifies an adverse reaction or overdose specifically due to substances classified as irritant cathartics. These agents stimulate bowel evacuation through direct irritation of the intestinal mucosa, and their misuse or accidental ingestion can lead to significant gastrointestinal distress and systemic effects.

Use this code when documentation clearly indicates a patient's signs and symptoms are a direct result of poisoning by an irritant cathartic, such as senna, bisacodyl, or castor oil. This applies to both accidental and intentional overdose scenarios. The medical record should specify the substance involved and the resulting toxic effects.

• Always code the specific irritant cathartic if known, using an E-code from the E850-E869 series to identify the external cause.
• Do not confuse this with poisoning by saline or bulk-forming laxatives, which fall under different code categories.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, followed by codes for any associated manifestations (e.g., dehydration, electrolyte imbalance).
