Poisoning by anticoagulants, intentional self-harm, init

This code signifies a patient presenting with adverse effects from an anticoagulant medication, where the ingestion or administration was a deliberate act of self-harm. The "initial encounter" indicates that this is the first time the patient is being seen for this specific poisoning event, requiring active treatment.

Use this code when a patient is admitted to the emergency department or hospital due to an overdose of anticoagulants, such as warfarin or heparin, with documented intent of self-harm. This applies when the patient is actively receiving medical management for the toxic effects of the anticoagulant.

• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
• Remember to also code any specific manifestations of the poisoning (e.g., hemorrhage, organ damage).
• Do not use this code for accidental poisonings or adverse effects from therapeutic use; those require different codes.
