CPT code 47381 denotes open cryosurgical ablation of one or more liver tumors, a surgical ablative technique performed through an open abdominal approach. Nationally, this code captures complex operative management of hepatic neoplasms where cryoablation is selected for tumor destruction, often in settings where percutaneous or laparoscopic techniques are not suitable. The code matters for hospitals and surgical teams because it reflects a resource-intensive inpatient or operating-room procedure with implications for perioperative care, anesthesia, and post-procedural monitoring.
