Poisn by unsp agents aff the cardiovasc sys, slf-hrm, sqla

This code signifies a long-term consequence or residual effect stemming from an intentional self-poisoning event involving an unspecified substance that primarily impacted the cardiovascular system. This means the patient experienced a previous overdose or toxic exposure, and now presents with a chronic or permanent condition directly attributable to that past event. The original poisoning was a deliberate act of self-harm.

Apply this code when documenting a current, ongoing health problem that is a direct result of a past intentional self-poisoning by a cardiovascular agent, where the specific substance is unknown. This is appropriate for follow-up encounters addressing chronic cardiac arrhythmias, cardiomyopathy, or other persistent cardiovascular damage clearly linked to a prior self-inflicted overdose.

• Always sequence this "S" (sequela) code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current cardiovascular condition to a past intentional self-poisoning.
• If the specific substance is known, a more precise T46.x2S code should be used instead.
