Poisn by oth agents aff the cardiovasc sys, slf-hrm, sequela

This code signifies a long-term health problem resulting from an intentional self-poisoning event where the substance primarily impacted the cardiovascular system. The patient has recovered from the acute poisoning but now experiences ongoing cardiovascular sequelae, such as chronic arrhythmias, heart failure, or other persistent cardiac dysfunction directly attributable to the original toxic exposure.

Use this code when documenting a patient presenting with a chronic cardiovascular condition that is a direct consequence of a past intentional self-harm poisoning. This applies to follow-up encounters for managing these persistent cardiac issues, long after the acute poisoning event has resolved. It indicates the enduring impact of the self-inflicted toxic exposure on the heart and circulatory system.

• Always assign this code as a secondary diagnosis, following the code for the specific cardiovascular sequela (e.g., I47.1 for paroxysmal supraventricular tachycardia).
• Ensure documentation clearly links the current cardiovascular condition to a past intentional self-harm poisoning event.
• The "S" seventh character indicates a sequela, meaning the residual effect of a past injury or illness. Do not use for acute poisoning.
