Poisoning by oth antihypertensive drugs, self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from an intentional overdose of antihypertensive medications other than ACE inhibitors, calcium channel blockers, or beta-blockers. The poisoning was a deliberate act of self-harm, and the current encounter is not the initial treatment for the acute event.

This code is appropriate for subsequent encounters where a patient is being managed for the sequelae of an intentional self-poisoning with antihypertensive drugs not specified elsewhere. Examples include psychiatric evaluations following stabilization, management of organ damage (e.g., kidney injury) resulting from the overdose, or follow-up for persistent hypotension.

• Always sequence this code after the primary diagnosis for the specific complication or reason for the encounter.
• Do not use this code for the initial acute poisoning event; use the appropriate initial encounter code (T46.5X2A) instead.
• Ensure documentation clearly specifies "intentional self-harm" and "subsequent encounter" to support the use of this specific subcategory.
