Medical necessity criteria and coverage guidance for pediatric kidney transplantation for non‑Medicare health plans affiliated with Centene/AZ Complete Health, applicable to members under 18 years of age.
Updated GFR criterion for ESRD from ≤ 15 mL/min/1.73m2 to < 15 mL/min/1.73m2 to align with KDIGO and OPTN guidance.
Added CKD stage 4 criterion: GFR < 30 mL/min/1.73m2 in members expected to reach ESRD.
Contraindication I.B.2 (HIV) updated to require documented CD4 > 200 cells/mm3, absence of active AIDS‑defining opportunistic infection, and current effective ART.
Coverage and Medical Necessity Criteria
Initial transplant candidacy (medical necessity)
Covered when ALL of the following are met:
Derived from policy criteria and KDIGO/OPTN guidance
Patients with GFR > 30 who are rapidly progressing should be referred for evaluation.
See HIV‑specific node for required HIV documentation.
These conditions allow consideration of transplant in virologically/immunologically controlled HIV.
Candidate selection
Candidates must meet disease severity and contraindication rules:
Referral for transplant evaluation should be considered for rapidly progressing patients even if GFR > 30.
HIV allowed only if documented CD4 >200, no active AIDS‑defining infection, and on effective ART.
The following conditions are listed as contraindications to pediatric kidney transplantation. Active infection that is not properly treated is a contraindication, with the specific exception of hepatitis C virus when managed per guidance. HIV is a contraindication when there is a detectable viral load unless all of the following are documented: CD4 cell count > 200 cells/mm3, absence of active AIDS‑defining opportunistic infection, and the member is currently on effective antiretroviral therapy (ART). Active malignancy with a high risk of recurrence or death related to cancer is excluded. Recent cerebrovascular events are excluded: stroke within the past 6 months or transient ischemic attack within the past 3 months.
Transplantation is considered not medically necessary for pediatric members who do not meet the advanced renal disease thresholds required for candidate selection. Specifically, candidates must meet one of the disease severity criteria (either ESRD with GFR < 15 mL/min/1.73m2 or CKD stage 4 with GFR < 30 mL/min/1.73m2 in members expected to progress to ESRD). In addition, transplantation is not medically necessary for members who have any of the contraindications listed in this policy (see contraindications).
Contraindications and Conditions That May Result in Denial
Providers must confirm the absence of the listed contraindications or supply documentation demonstrating the condition has been treated, is controlled, or has appropriate specialist clearance prior to authorization.
Required documentation to support medical necessity
Include required supporting documentation with the authorization request. Insufficient or missing documentation may lead to denial.
- Clinical records confirming absence or effective treatment of active infection (culture results, treatment notes)
- For HIV+ patients: most recent viral load and CD4 count, documentation of absence of AIDS‑defining opportunistic infections, and proof of current effective ART regimen
- Oncology records showing cancer status, staging, treatment history, and risk assessment for recurrence if prior malignancy exists
- Neurology/cardiology consult notes or clearance for recent stroke, TIA, or myocardial infarction
- Cardiology evaluation for active symptomatic cardiac disease and formal clearance if indicated
- Vascular surgery or specialist notes documenting management of peripheral arterial disease
- Behavioral health and social work assessments addressing adherence potential and caregiver support
- Substance use evaluation, treatment records, and evidence of stability/engagement in treatment when applicable
- Hepatology documentation for cirrhosis and multidisciplinary plan if combined transplant under consideration
- Laboratory evidence for anti‑glomerular basement membrane antibody levels and nephrology interpretation
Required Evaluation and Pre-Transplant Assessment
Multidisciplinary evaluation and cardiology clearance required
A comprehensive multidisciplinary pre‑transplant evaluation is required; the cause of ESRD should be determined when possible and cardiology evaluation/clearance is required for active cardiac disease or after myocardial infarction.
- Multidisciplinary evaluation recommended for candidate selection
- Determine cause of ESRD when possible to inform post‑transplant management
- Cardiology evaluation required for active symptomatic cardiac disease; cardiology clearance required after myocardial infarction
Document GFR, contraindication status, and evaluation/clearance
Documentation must demonstrate advanced renal disease using GFR values: ESRD defined as GFR < 15 mL/min/1.73m2 or CKD stage 4 with GFR < 30 mL/min/1.73m2 when the member is expected to reach ESRD; records should also show absence of contraindications and required candidate evaluations (e.g., cardiology clearance, HIV labs and ART documentation).
- GFR values supporting ESRD: GFR < 15 mL/min/1.73m2
- CKD stage 4: GFR < 30 mL/min/1.73m2 with expectation to progress to ESRD
- Evidence of absence of listed contraindications and results of multidisciplinary evaluation (e.g., cardiology clearance, HIV CD4/viral load, ART)
Provider Requirements, Prior Authorization, and Billing Guidance
Obtain prior authorization using referenced procedure/HCPCS codes
Prior authorization is implied for pediatric kidney transplantation and associated donor/procurement and implantation services; use the referenced CPT and HCPCS codes when seeking authorization and submitting claims.
No step therapy specified; preemptive transplant recognized
No step therapy or sequencing requirements are specified by this policy; preemptive (living donor) transplantation is recognized as the preferred option when appropriate and feasible.
- Policy does not mandate prior dialysis or other sequencing before transplant
- Preemptive transplantation from a living donor is preferred when feasible

Policy Definitions
Background and Scope
Kidney transplantation is the preferred treatment for pediatric patients with advanced chronic kidney disease or end‑stage renal disease because it improves survival, quality of life, and growth—outcomes that are particularly important in children. When feasible, preemptive transplantation from a living donor is preferred. Candidates should undergo multidisciplinary evaluation and, when possible, determination of the cause of ESRD to inform candidacy and perioperative planning.
Transplant Center Expectations
Center must follow KDIGO/OPTN guidance; accreditation expectations implied
Policy references KDIGO and OPTN guidance for candidate evaluation and implies transplant center accreditation expectations; specific center certification (e.g., FACT) is not enumerated but adherence to guideline‑based evaluation is expected.
- Referenced sources: KDIGO 2020 guideline and OPTN educational guidance for patient referral
- Implied expectation that transplant centers follow guideline‑based evaluation and established accreditation standards
