Description
Cryosurgical ablation of the kidney (also called cryosurgery, cryotherapy, or cryodestruction) is the use of extreme cold to destroy cancer cells while preserving the surrounding healthy tissue.
Radiofrequency ablation (RFA) is a type of treatment for malignant renal tumors. This technique uses heat to destroy cancerous cells.
Criteria
Cryosurgical ablation of renal cell carcinoma may be considered medically necessary for select patients with small renal cell carcinoma less than or equal to 4cm when ANY ONE of the following criteria is met:
- Individuals who are considered high-risk surgical candidates; or
- Individuals with renal insufficiency, as defined by a glomerular filtration rate of less than or equal to 60 ml/min/m2; or
- Individuals with a solitary kidney.
Cryosurgical ablation is considered not medically necessary for renal cell carcinoma that does not meet the above criteria.
