Anesthesia Coding Practice Test

The main concept here is that anesthesia coding reflects the procedure, the patient’s ASA physical status, and any extra service due to high-risk preoperative conditions. For a radical perineal prostatectomy, the procedure-specific anesthesia code is 00904. The patient has severe systemic disease (CAD, hypertension, COPD), which corresponds to ASA Physical Status 3, so you add the modifier -P3 to indicate ASA-PS 3. Because these significant systemic diseases increase intra- and preoperative risk, there’s an additional anesthesia service captured with 99100. So the correct combination is the procedure code 00904 with the ASA status modifier -P3, plus 99100 to reflect the extra risk-related anesthesia evaluation/monitoring. The other options use different base procedure codes or omit the ASA status or the extra 99100 service, which is why they’re not appropriate here.
