X63: Intentional self-poisoning by and exposure to other drugs acting on the autonomic nervous system

The group of conditions coded under X63 pertains to the intentional self-poisoning by, and exposure to, other drugs acting on the autonomic nervous system. These conditions involve the deliberate misuse of drugs, medication or substances that affect the automatic functions of the body, such as heart rate, digestion, respiratory rate, salivation, perspiration, urination, and sexual arousal. Depending on the substance used, symptoms can range from behavioral changes, breathing difficulties, and alterations in heart rate and blood pressure, to severe systemic reactions such as seizures or unconsciousness. Progression can be rapid and potentially life-threatening. Overdose, toxicity or poisoning by these drugs can damage numerous systems in the body, including the cardiovascular, respiratory, digestive, and central nervous system. These conditions typically result from self-inflicted harm or suicide attempts, emphasizing the need for mental health awareness and support.
