Poisn by unsp agents aff the cardiovasc sys, self-harm, subs

This code signifies a patient presenting for follow-up care after intentionally self-poisoning with an unknown substance that primarily impacted their heart and circulatory system. The initial acute phase of treatment has concluded, and the patient is now receiving ongoing management for the effects of the poisoning.

Apply this code when documenting subsequent encounters for patients who previously attempted suicide via an unspecified cardiovascular-acting agent. This includes follow-up appointments for cardiac monitoring, medication adjustments, or management of residual cardiovascular complications stemming from the self-harm event.

• Ensure documentation clearly indicates "intentional self-harm" and "subsequent encounter."
• Only use this code when the specific agent is unknown; if identified, a more specific T-code should be used.
• Always code the underlying mental health condition (e.g., depression) as an additional diagnosis.
