Poisoning by calcium-channel blockers, assault, init encntr

This code signifies a patient presenting with adverse effects from calcium-channel blocker medication due to an intentional act of harm by another person. The patient is in the acute phase of treatment for this poisoning.

This code is appropriate when a patient has been deliberately administered an overdose of a calcium-channel blocker by another individual, resulting in toxic effects. It should be used for the initial visit or encounter where the poisoning is being evaluated and treated.

• Always assign an additional code for the specific manifestation of the poisoning (e.g., hypotension, bradycardia).
• Ensure documentation clearly states the poisoning was due to an assault, not accidental or self-harm.
• Verify the encounter is the "initial encounter" for this specific poisoning event.
