Toxic gastroenteritis and colitis

📋Clinical Description

This code represents inflammation of the stomach and intestines (gastroenteritis) and/or colon (colitis) caused by exposure to a toxic substance. This condition is typically acute and results from ingestion or contact with irritants, poisons, or certain medications, leading to symptoms like nausea, vomiting, diarrhea, and abdominal pain.

🎯When to Use

Use this code when documentation clearly indicates gastroenteritis or colitis due to a specific toxic agent, such as food poisoning from bacterial toxins, chemical irritants, or adverse reactions to ingested substances. The medical record should specify the toxic etiology rather than an infectious or allergic cause.

💡Coding Tips

Distinguish from infectious gastroenteritis (A00-A09) or allergic gastroenteritis (K52.2) based on documented etiology.
If the specific toxic agent is known, consider an additional code from T36-T65 to identify the substance.
Ensure documentation specifies "toxic" as the cause; otherwise, an unspecified gastroenteritis code may be more appropriate.
