Adverse effect of angiotens-convert-enzyme inhibitors, subs

This code signifies a harmful or unintended reaction to an ACE inhibitor medication that occurs during a follow-up visit or ongoing treatment. It indicates that the patient is experiencing an adverse effect, rather than an intentional overdose or poisoning, from a drug prescribed and taken correctly.

Apply this code when a patient presents for management of an adverse reaction to an ACE inhibitor, such as angioedema, persistent cough, or hyperkalemia, and this is not the initial encounter for the adverse effect. This is appropriate for subsequent visits where the adverse effect is being monitored, treated, or evaluated further.

• Always sequence this code after the code for the specific adverse effect (e.g., angioedema, cough).
• Ensure the "D" seventh character is appropriate for a subsequent encounter; "A" is for initial, "S" for sequela.
• Verify that the medication in question is indeed an ACE inhibitor to ensure accurate coding.
