Poisoning by anticoagulants, assault, initial encounter

This code signifies a patient presenting with adverse effects resulting from the intentional administration of an anticoagulant with the intent to harm. The poisoning is due to an assault, and this code is used for the initial phase of treatment for the acute toxic effects.

Apply this code when documentation clearly indicates that an anticoagulant was forcibly or deceptively given to a patient by another individual, leading to poisoning. This is appropriate for the initial hospital visit or encounter where the poisoning is first diagnosed and treated.

• Ensure the documentation explicitly states "assault" as the intent of the poisoning.
• Verify that the substance involved is an anticoagulant; do not use for other drug classes.
• The "A" at the end indicates an initial encounter, meaning this is for the active treatment phase.
