Anesthesia Coding Practice Test

In anesthesia coding, you bill the base anesthesia code that matches the procedure, then add modifiers for the patient’s status and any additional documented services.

For transurethral resection of the prostate, the base anesthesia code is 00914, which covers anesthesia for prostate/genitourinary procedures. The patient has hypertension and Parkinson’s disease, which are systemic diseases, placing him at ASA physical status II; therefore you attach the modifier P2 to reflect this ASA II status.

In addition, because an anesthesia preoperative evaluation and management service was performed and documented for a patient with systemic disease, the code 99100 is added to account for the separate preoperative assessment.

Thus, combining 00914-P2 with 99100 best represents both the anesthesia for the TURP and the preoperative evaluation.

The other options don’t fit because they would either omit the preoperative evaluation (just the base code with ASA status) or omit the actual anesthesia service, or use a base code that corresponds to a different procedure or patient risk level.
