Poisoning by calcium-channel blockers, self-harm, sequela

This code signifies a long-term consequence or complication arising from an intentional self-harm attempt involving calcium-channel blocker poisoning. It indicates that the acute phase of the poisoning has passed, but the patient is still experiencing residual effects directly attributable to that event. These sequelae can range from organ damage (e.g., cardiac, renal) to neurological deficits or other chronic health issues.

This code is appropriate when a patient presents with a current health problem that is a direct result of a past intentional self-harm attempt via calcium-channel blocker overdose. This would apply to follow-up visits where the focus is on managing these chronic complications, rather than the acute poisoning itself. Examples include ongoing cardiac arrhythmias, kidney dysfunction, or neurological impairment stemming from the original poisoning.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Do not use this code for the initial acute poisoning event; use the appropriate acute poisoning code.
• Ensure documentation clearly links the current condition to the past intentional self-harm by calcium-channel blockers.
