Poisoning by calcium-channel blockers, assault, subs encntr

This code signifies a patient presenting for follow-up care related to an intentional overdose of calcium-channel blockers, where the poisoning was inflicted by another person. The patient is no longer in the acute phase of treatment but is receiving ongoing management for the effects of the poisoning.

This code is appropriate for encounters such as follow-up appointments for cardiac monitoring, electrolyte imbalance management, or psychiatric evaluation after the initial acute care for an assault-related calcium-channel blocker poisoning. It should be used when the patient is receiving subsequent care for the sequelae of the poisoning event.

• Always assign an additional code for the specific adverse effects or complications resulting from the poisoning.
• Ensure documentation clearly supports that the poisoning was an assault and that this is a subsequent encounter.
• Do not use this code for initial encounters or for poisonings that were accidental or self-harm.
