Poisoning by angiotens-convert-enzyme inhibitors, acc, init

This code signifies an accidental overdose or adverse reaction to an ACE inhibitor medication, such as lisinopril or enalapril, due to unintentional ingestion or administration. The patient is experiencing the initial effects and receiving active treatment for the poisoning.

Apply this code when a patient presents to an emergency department or clinic with symptoms of ACE inhibitor toxicity (e.g., severe hypotension, angioedema, hyperkalemia) resulting from an accidental ingestion or an unintentional overdose. This code is appropriate for the initial visit where the poisoning is being diagnosed and managed.

• Always assign an additional code for the specific manifestation of the poisoning (e.g., R03.1 for hypotension, T78.3XXA for angioedema).
• Ensure documentation clearly states the accidental nature of the poisoning and that it is the initial encounter for treatment.
• Distinguish from adverse effects of properly administered drugs, which would use a different code from the T36-T50 range with a 5th or 6th character indicating adverse effect.
