Anesthesia Coding Practice Test

The key idea is to code the anesthesia service based on the procedure performed and adjust for patient status and age. For a permanent transvenous pacemaker implantation (a procedure on the heart/great vessels), the appropriate base anesthesia code is 00530. The patient has severe atrial fibrillation, which places him in ASA physical status III, so you attach the modifier -P3 to reflect this severe systemic disease.

In addition, the patient is 72 years old, which meets the criteria for the extreme age code 99100 (anesthesia for patient over 70 or under 1 year). This code is added to reflect the patient’s age.

Therefore, the correct pairing is 00530-P3 with 99100. The other options use incorrect base codes for this procedure or incorrect modifiers, so they don’t fit the scenario.
