Poisoning by calcium-channel blockers, assault, sequela

This code indicates a long-term health problem or complication that has arisen as a direct result of a previous poisoning by calcium-channel blockers, where the poisoning was intentionally inflicted by another person. The patient is no longer in the acute phase of the poisoning but is experiencing residual effects.

Use this code when documenting a patient presenting with chronic organ damage (e.g., cardiac, renal), neurological deficits, or other lasting health issues directly attributable to a past assault involving calcium-channel blocker overdose. This applies when the acute poisoning event has resolved, and the current encounter addresses these persistent sequelae.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., I42.0 for cardiomyopathy).
• Ensure documentation clearly links the current condition to a past calcium-channel blocker poisoning by assault.
• Do not use for acute poisoning events; use the appropriate acute poisoning code with the 7th character 'A' or 'D'.
