Poisoning by oth antihypertensive drugs, assault, init

This diagnosis code indicates an intentional overdose or harmful exposure to antihypertensive medications, excluding ACE inhibitors, beta-blockers, calcium channel blockers, and diuretics, with the intent to cause harm to the patient (assault). The "initial encounter" signifies that the patient is receiving active treatment for the acute effects of this poisoning.

Use this code when documenting a patient presenting with symptoms of poisoning due to antihypertensive drugs, where the circumstances clearly indicate an assault. This applies to the initial hospital visit or emergency department encounter for the acute management of the overdose.

• Ensure documentation explicitly states "assault" as the intent of the poisoning.
• Verify the specific antihypertensive drug involved is not an ACE inhibitor, beta-blocker, calcium channel blocker, or diuretic.
• Confirm this is the first encounter for the acute phase of treatment; subsequent care would use a different encounter character.
