HCPCS Level II code S2140 represents cord blood harvesting performed for allogeneic transplantation. This procedure is a key step in preparing donor-derived umbilical cord blood for hematopoietic stem cell transplantation, supporting treatments for hematologic malignancies, immunodeficiencies, and other marrow failure conditions. Nationally, proper coding of cord blood collection affects coverage determinations, transplant center billing workflows, and resource allocation for specialized collection services.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context, typical sites of service, and the role of S2140 in transplant care pathways. The publication summarizes payer coverage patterns, common modifier usage, and billing considerations where available.
