Poisoning by methaqualone compounds

This code signifies an adverse health effect resulting from the ingestion, inhalation, or absorption of methaqualone compounds, whether accidental or intentional. It represents a toxic reaction to this specific sedative-hypnotic drug, leading to various physiological disturbances.

Use this code when documentation clearly indicates a patient's condition is due to poisoning by methaqualone. This includes overdose, adverse effects from recreational use, or accidental ingestion. Supporting documentation should specify methaqualone as the causative agent.

• Always code the manifestation of the poisoning first, if applicable (e.g., coma, respiratory depression).
• Distinguish between poisoning (adverse effect due to improper use or overdose) and adverse effect in therapeutic use (E-code for adverse effect).
• Ensure documentation specifies "methaqualone" and not a general sedative or hypnotic.
