Simultaneous Liver Kidney Transplantation
Kidney transplant as part of a simultaneous liver kidney (SLK) transplantation is considered medically necessary when criteria for liver transplantation are met and when one of the following are met:

• The individual has acute renal failure secondary to either hepatorenal syndrome or acute kidney injury; either of which have required at least 6 weeks of dialysis therapy; or
• The individual has chronic kidney disease with a measured creatinine clearance of less than or equal to 30cc/min; or
• The individual has prolonged acute kidney failure or kidney failure of unknown cause and a renal biopsy showing fixed renal damage.

Not Medically Necessary:

Kidney transplantation for conditions other than end stage renal disease is considered not medically necessary.

Kidney transplantation as part of a simultaneous liver kidney (SLK) transplant is considered not medically necessary, if one of the above SLK criteria is not met.

Note: For multi-organ transplant requests, criteria must be met for each organ requested. In those situations, an individual may present with a concurrent medical condition which may be considered an exclusion or a comorbidity that would preclude a successful outcome, but would be treated with the additional organ transplant. Such cases will be reviewed on an individual basis for coverage determination to assess the member’s candidacy for transplantation.

General Individual Selection Criteria

In addition to having one of the clinical indications above, the member must not have a contraindication as defined by the American Society of Transplantation in Guidelines for the Referral and Management of Patients Eligible for Solid Organ Transplantation (2001) listed below.*

Absolute Contraindications- for Transplant Recipients include, but are not limited to, the following:

1. Metastatic cancer
2. Ongoing or recurring infections that are not effectively treated
3. Serious cardiac or other ongoing insufficiencies that create an inability to tolerate transplant surgery
4. Serious conditions that are unlikely to be improved by transplantation as life expectancy can be finitely measured
5. Demonstrated patient noncompliance, which places the organ at risk by not adhering to medical recommendations
6. Potential complications from immunosuppressive medications are unacceptable to the patient
7. Acquired immune deficiency syndrome (AIDS) (diagnosis based on Centers for Disease Control and Prevention [CDC] definition of CD4 count, 200cells/mm³) unless the following are noted:
   1. CD4 count greater than 200cells/mm³ for greater than 6 months
   2. HIV-1 RNA undetectable
   3. On stable anti-retroviral therapy greater than 3 months
   4. No other complications from AIDS (for example, opportunistic infection, including aspergillus, tuberculosis, coccidioidomycosis, resistant fungal infections, Kaposi’s sarcoma or other neoplasm)
   5. Meeting all other criteria for kidney transplantation

Discussion/General Information

Approximately 37 million Americans were reported to have chronic kidney disease (CKD), with nearly 118,000 requiring initiation of treatment for kidney failure known as end stage renal disease (ESRD) each year (CDC, 2021). There was a steady rise in the rate of ESRD from 1980 to 2011; the incident rate of ESRD has started to decline. As of December 2021, the Organ Procurement and Transplantation Network (OPTN) reported that there were 97,958 Americans on the wait list for kidney transplantation and, in 2020, a total of 22,817 kidney transplants were performed (OPTN, 2021). According to data from the OPTN, for individuals receiving primary kidney transplants between 2008 and 2015, the 1-, 3- and 5-year survival rates were 97.1%, 92.9% and 86.3%, respectively.

A kidney transplant involves the surgical removal of a kidney from a deceased or living donor and implantation into a recipient. A donor left kidney is usually transplanted to the right iliac fossa with the renal artery anastomosed end-to-end to the hypogastric artery and the renal vein end-to-side to the common iliac vein. The ureter is implanted into the bladder and (under special conditions) a uretero-ureteral anastomosis or ureteropyelostomy may be performed.

Hepatorenal syndrome is a severe complication of liver cirrhosis or other severe liver disease. Features of hepatorenal syndrome are renal dysfunction caused by abnormalities in the arterial circulation and the vasoactive systems, resulting in renal vasoconstriction and renal insufficiency. There are two types of hepatorenal syndrome. Type I hepatorenal syndrome occurs when renal function is rapidly reduced and has an ominous prognosis which is usually reversed by liver transplantation. Type II hepatorenal syndrome occurs when renal failure does not progress rapidly. It can be quite difficult to distinguish these two conditions in individuals with severe liver disease. Liver transplantation is the recognized treatment for hepatorenal syndrome (Davis, 2005; Marik, 2006).

Concern has been raised since the introduction of the MELD (model for end-stage liver disease) prioritization for liver transplant that some recipients that undergo combined liver and kidney transplantation may have reversible renal failure. To address this issue, the American Society of Transplantation and American Society of Transplant Surgeons met in March 2006 to review post-MELD data on the impact of renal function on liver waitlist and transplant outcomes and the result of simultaneous liver kidney transplantation. This committee issued a consensus statement with regard to simultaneous liver-kidney (SLK) transplantation summarized below (Davis, 2007):

• In the setting of chronic kidney disease, a measured creatinine clearance of less than or equal to 30cc/min was considered the appropriate threshold for SLK transplantation.
• In the setting of acute renal failure secondary to hepatorenal syndrome or acute kidney injury, renal dysfunction requiring dialysis reflects a decreased capacity for renal recovery and SLK transplantation is considered appropriate. The committee through consensus established a six (6) weeks dialysis duration threshold prior to SLK transplantation.
• In individuals with prolonged acute kidney failure or kidney failure of unknown cause and a renal biopsy showing fixed renal damage (e.g. greater than 30-50% glomerulosclerosis, arteriolar hyalinosis, tubular atrophy, interstitial fibrosis) SLK may be medically necessary.
• In the setting of acute renal failure including hepatorenal syndrome not requiring dialysis, SLK transplantation was not felt to be medically necessary or appropriate. In reaching this consensus, the committee determined that liver transplant recipients with a glomerular filtration rate (GFR) of less than 30cc/min had a 1-year post-transplant survival of 81.5% and only 25/1648 (1.5%) of these recipients were listed for kidney transplant within a year of liver transplantation.

The 2020 Kidney Disease Improving Clinical Outcomes (KDIGO) clinical practice guideline on evaluation and management of candidates for kidney transplantation, developed by an international group of experts, recommended that individuals with chronic kidney disease who are expected to reach end-state kidney disease be considered for kidney transplantation, except for individuals with the following conditions:

• Multiple myeloma, light chain deposition disease or heavy chain deposition disease unless they have successfully received a curative treatment;
• AL amyloidosis with significant extrarenal involvement;
• Decompensated cirrhosis (these individuals can be considered for SLK);
• Severe irreversible obstructive or restrictive lung disease; and
• Severe uncorrectable symptomatic cardiac disease determined by a cardiologist to preclude transplantation.

In addition, the KDIGO guideline recommends that kidney transplant evaluation be delayed for individuals with the following conditions until they have been satisfactorily managed:

• Unstable psychiatric disorder or current substance abuse disorder that affects decision-making and puts the individual at an unacceptable level of post-transplant risk;
• Ongoing health-compromising behavior;
• Active infection that is not properly treated (excluding hepatitis C);
• Active malignancy other than indolent and low-grade cancers;
• Active symptomatic cardiac disease that has not been evaluated by a cardiologist;
• Active symptomatic peripheral arterial disease;
• Recent stroke or transient ischemic attack;
• Active peptic ulcer disease, diverticulitis, acute pancreatitis, gallstone or gallbladder disease or inflammatory bowel disease;
• Acute hepatitis; or
• Severe hyperparathyroidism.

In 2017, United Network of Organ Sharing (UNOS) implemented policy changes for SLK transplantation based on changes the UNOS/Organ Procurement and Transplant Network (OPTN) board recommended. The decision was made based on subjective criteria to implement the new SLK allocation policy to standardize utilization for SLK. Individuals meeting the SLK allocation policy are defined based on the following criteria: sustained kidney injury with estimated glomerular filtration rate (eGFR) < 60 mL/min for 90 days or more with a final eGFR <30 mL/min.  (UNOS, 2022)

Controlled HIV infection is not considered a contraindication to kidney transplant (Chadban, 2020). In 2019, Zheng and colleagues published a meta-analysis of studies on outcomes after kidney transplantation in HIV-positive individuals. The meta-analysis included 27 cohort studies and 1670 case series published between July 2003 and May 2018. The authors found a pooled 1-year survival rate of 97% and a 5-year survival rate of 94%.
