Poisn by cardi-stim glycos/drug simlar act, self-harm, init

This code signifies a patient presenting with adverse effects from an intentional overdose of cardiac glycosides or similar heart-stimulating medications. These substances, often used to treat heart failure or arrhythmias, become toxic when taken in excessive amounts, leading to symptoms like nausea, vomiting, vision changes, and potentially life-threatening cardiac dysrhythmias. The "initial encounter" indicates the patient is actively receiving treatment for the acute poisoning.

Apply this code when documenting a patient's initial presentation and treatment for self-inflicted poisoning by medications such as digoxin, digitoxin, or other cardiac stimulants. This is appropriate for emergency department visits, inpatient admissions, or initial outpatient encounters where the primary reason for the visit is the acute management of the overdose.

• Ensure documentation clearly states "intentional self-harm" as the intent of the poisoning.
• Verify the specific substance involved is a cardiac-stimulant glycoside or drug of similar action.
• Confirm this is the patient's first encounter for this specific poisoning episode; subsequent care would use a different encounter character.
