What 32997 covers
Total lung lavage washes an entire lung to remove accumulated material from the air spaces, most commonly in a patient with pulmonary alveolar proteinosis. In a controlled operating-room setting, the lung being treated is isolated while the other lung is ventilated; warmed saline is introduced and drained in repeated cycles. A thoracic surgeon or pulmonologist typically performs the lavage with anesthesia support. The procedure treats a whole lung rather than a focal lesion or an individual airway.
Report the service when the operative record supports therapeutic lavage of the entire lung, including the indication, side treated, lung-isolation approach, and lavage performed. For bilateral treatment, CMS recognizes modifier 50 and pays the bilateral procedure at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. The 0-day global period includes same-day preoperative and postoperative care. Medicare does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.

How to choose
- 32999Unlisted px lungs & pleura
- Use 32997 when the service is whole-lung lavage. Consider 32999 only when the lung or pleural procedure performed is not accurately represented by a specific listed code.
- 32960Therapeutic pneumothorax
- 32960 describes therapeutic pneumothorax. It does not represent saline washing and drainage of an entire lung.
- 32994Lung tumor ablation
- 32994 describes percutaneous cryoablation of a pulmonary tumor. It targets a focal tumor rather than washing an entire lung.
- 32998Lung tumor ablation
- 32998 describes percutaneous radiofrequency ablation of a pulmonary tumor. Use 32997 for therapeutic whole-lung lavage, not focal tumor ablation.
32997 billing questions
When is 32997 appropriate instead of a lung tumor ablation code?

How should bilateral lavage be reported?
When both lungs are treated, report the bilateral service with modifier 50. CMS pays the bilateral procedure at 150%.
What documentation supports 32997?
Document the therapeutic indication, the side or sides treated, lung isolation, and the lavage performed. The record should make clear that the service involved whole-lung washing rather than a focal airway or tumor procedure.
How does the multiple-procedure reduction affect 32997?
For procedures performed in the same session, CMS pays the highest-valued procedure in full and other procedures at 50%. Which procedure receives the reduction depends on the relative values of the services reported.
Can an assistant or co-surgeon be reported for this procedure?
Medicare does not pay an assistant at surgery for 32997. Co-surgeons and team surgery are not permitted.
What care is included in the global period?
