What 47371 covers
A surgeon accesses the liver laparoscopically and applies a cryosurgical probe to freeze and destroy tumor tissue. Hepatobiliary surgeons and surgical oncologists typically perform this operation in an operating room when laparoscopic access and cryoablation are selected for treating hepatic tumor tissue. The service is distinct from liver wound repair and from ablation performed through an open or percutaneous approach.
The operative report should identify the laparoscopic approach, cryosurgical technique, and treated tumor site or sites. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 47370Liver tumor ablationLaparoscopic radiofrequency
- Both involve laparoscopic liver tumor ablation. Choose 47371 for cryosurgical freezing and 47370 for radiofrequency ablation.
- 47381Liver tumor ablationOpen cryosurgical approach
- Both use cryosurgery for liver tumor tissue, but 47381 is the open approach; 47371 is laparoscopic.
- 47383Liver ablationPercutaneous cryoablation
- Both use cryoablation, but 47383 is performed percutaneously. Report 47371 for laparoscopic access.
- 47382Liver ablationPercutaneous radiofrequency
- 47382 describes percutaneous radiofrequency ablation of a liver tumor. It differs from 47371 in both approach and ablation method.
47371 billing questions
How does 47371 differ from 47370?
Both describe laparoscopic liver tumor ablation, but 47371 involves cryosurgical freezing while 47370 uses radiofrequency energy. Match the code to the documented ablation method.
When would 47383 be reported instead?
47383 describes percutaneous liver cryoablation. Use 47371 when the surgeon performs the cryosurgical treatment laparoscopically.
Should modifier 50 be appended for tumors in both lobes?
No. CMS identifies bilateral adjustment as inappropriate for this code; the descriptor or anatomy does not support modifier 50.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
What should the operative note establish?
Document the laparoscopic approach, use of cryosurgical ablation, and the liver tumor site or sites treated. These details distinguish this service from radiofrequency ablation and from open or percutaneous cryoablation.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
