Adverse effect of coronary vasodilators, subs encntr

This code signifies an undesirable or harmful reaction experienced by a patient due to the therapeutic use of a coronary vasodilator medication, occurring during a follow-up visit or after the initial treatment phase. These adverse effects can range from mild to severe and are not due to an overdose or poisoning.

This code is appropriate when a patient presents for ongoing management or evaluation of a known adverse effect from a coronary vasodilator. This includes situations where the patient is being monitored for resolution of the adverse effect, or when the treatment plan for the adverse effect is being adjusted. It is used after the initial encounter for the adverse effect.

• Always sequence this code after the code for the specific adverse effect being treated.
• Ensure documentation clearly states the adverse effect is due to a coronary vasodilator and that it's a subsequent encounter.
• Distinguish from initial encounters (A), subsequent encounters (D), and sequela (S) by carefully reviewing the encounter type.
