Anesthesia Coding Practice Test

The key idea is matching the anesthesia code to the surgical site and the patient’s ASA status. For a thyroidectomy, the procedure is in the neck, so the base anesthesia code that covers neck procedures is used, and you add the ASA status modifier to reflect the patient’s health. Here, the neck-area anesthesia code is 00320, and the patient is normally healthy, so you attach the ASA status modifier -P1. That makes the appropriate report 00320-P1. The other options don’t fit because: - 00160-P1 would correspond to a different anatomical site and isn’t the neck/thyroid code. - 01960-P3 implies a different procedure/site and a much sicker patient (ASA III), which isn’t accurate here. - 99100 is a sedation code, not the anesthesia service code for a thyroidectomy performed under general anesthesia.
