CPT code 50370 designates the surgical removal of a previously transplanted donor kidney from a recipient because of graft rejection. This procedure is clinically significant given the complexity of transplant surgery, the high-acuity setting in which it is performed, and the downstream implications for patient morbidity, infection risk, and potential relisting for transplant. Nationally, management of failed renal allografts affects hospital resource use, surgical specialty workflows, and transplant program reporting.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines how coverage and coding practices intersect with clinical documentation and inpatient surgical care for explantation of renal allografts.

Readers will find concise benchmarks and coding context, an overview of payer coverage patterns where available, and clinical context for when CPT code 50370 is used. The piece summarizes typical sites of service, common clinical scenarios prompting explantation, and policy-relevant considerations for billing and hospital service lines. Data not available in the input is identified as such where applicable.
