Poisoning by chloral hydrate group

This code signifies an adverse effect resulting from the ingestion or exposure to chloral hydrate or related compounds. It encompasses both accidental and intentional overdoses, as well as therapeutic misadventures leading to toxic effects. The poisoning can manifest with central nervous system depression, respiratory depression, hypotension, and cardiac arrhythmias.

Use this code when documentation clearly indicates a patient's signs and symptoms are directly attributable to chloral hydrate poisoning. This includes cases of acute intoxication, overdose, or adverse reactions to prescribed chloral hydrate. Supporting documentation should detail the substance involved, the route of exposure, and the resulting clinical presentation.

• Always code the specific manifestation of the poisoning (e.g., coma, respiratory failure) in addition to this code.
• Distinguish between poisoning (adverse effect due to incorrect use or overdose) and adverse effect in therapeutic use (E-code required).
• Review documentation carefully to identify if the poisoning was accidental, intentional self-harm, or assault, and assign the appropriate E-code.
