CPT code 48556 represents the surgical explantation of a previously transplanted donor pancreas when the graft fails to function. This code captures a complex, high-acuity operative service most commonly performed in the inpatient hospital setting and is relevant to transplant programs, hospital billing departments, and payers managing post-transplant complications. Nationally, pancreas graft failure and subsequent explant procedures carry significant clinical and resource implications for transplant centers and payers, including intensive perioperative care and potential impacts on readmission and length-of-stay metrics. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for pancreas explantation, typical sites of service, common payer coverage considerations, and benchmarking topics including utilization patterns and reimbursement factors where available. The publication also summarizes common modifier usage and highlights areas where additional coding detail or diagnosis linkage is often needed. Data not available in the input is explicitly noted where applicable.
