Poisoning by oth antihypertensive drugs, self-harm, sequela

This code signifies a long-term complication or residual effect resulting from a deliberate overdose of an antihypertensive medication other than those specifically classified elsewhere (e.g., ACE inhibitors, calcium channel blockers). These sequelae are the lasting health problems that persist after the initial acute poisoning event has resolved.

Apply this code when documenting chronic conditions or permanent damage directly attributable to a past intentional self-harm attempt involving an "other" antihypertensive drug. This is used for follow-up encounters after the acute poisoning has been treated, and the patient is presenting for management of the lasting effects.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, neurological deficit).
• Ensure documentation clearly links the current condition as a direct consequence of the past intentional self-harm poisoning.
• Do not use for the initial acute poisoning event; use the acute poisoning code with the appropriate seventh character for that encounter.
