Summary & Overview

HCPCS S2053: Small Intestine and Liver Transplantation

HCPCS Level II code S2053 represents combined transplantation of small intestine and liver allografts, a complex, high-acuity surgical procedure performed at specialized transplant centers. This code captures bundled reporting for simultaneous small bowel and liver transplant services, relevant to tertiary care hospitals and transplant programs. Nationally, combined organ transplants are resource-intensive, carry significant clinical complexity, and have implications for coverage policy, prior authorization, and post-transplant care coordination.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of where this code is used clinically, typical sites of service, and the payer landscape relevant to coverage and claims processing. The publication summarizes benchmarks and utilization context when available, highlights common administrative considerations for billing and claims adjudication, and outlines policy updates or guidance that affect transplant services at a national level.

This summary provides clinical context for revenue cycle and policy teams, transplant program administrators, and payers seeking to align coding, coverage, and care pathways for complex multi-organ transplantation.

Billing Code Overview

HCPCS Level II code S2053 describes transplantation of small intestine and liver allografts. This procedure involves the surgical implantation of combined small intestine and liver donor organs to replace nonfunctional native organs.

Service type: Combined organ transplant surgery
Typical site of service: Inpatient tertiary care centers or specialized transplant hospitals

Clinical & Coding Specifications

Clinical Context

A 42-year-old patient with end-stage liver disease complicated by irreversible intestinal failure is evaluated for combined small intestine and liver allograft transplantation. The patient has progressive liver cirrhosis with portal hypertension and recurrent episodes of bacterial translocation, plus short bowel syndrome with total parenteral nutrition dependence and frequent catheter-related sepsis. Multidisciplinary transplant assessment confirms suitability for combined organ transplant. The clinical workflow includes pre-transplant evaluation (medical, surgical, nutritional, infectious disease, and psychosocial assessments), listing and organ allocation, preoperative optimization (vascular access, nutritional support, infection control), the operative procedure S2053 (simultaneous transplantation of small intestine and liver allografts) performed in an inpatient tertiary transplant center, immediate postoperative intensive care with immunosuppression initiation and infection prophylaxis, staged enteric reconstruction as indicated, and longitudinal outpatient transplant follow‑up with surveillance for rejection and complications.
