Medical Coding Exam Prep

Answer: A - A pacemaker or pacing cardioverter-defibrillator that has pacing and sensing functions in three or more chambers of the heart is considered a multiple lead system. Pacemaker or cardioverter-defibrillator systems have electrical stimulation leads that help shock the heart into rhythm. Depending on the individual needs of the patient, some systems may have only one lead, while others may have two, three, or more electrical leads. Correct code selection depends on how many leads the system has.
