Arizona Complete Health Pediatric Kidney Transplant Policy Update

Coverage and Medical Necessity Criteria

Initial transplant candidacy (medical necessity)

Covered when ALL of the following are met:

Overall: Candidate is a pediatric member (age < 18) and meets advanced renal disease criteria and does not have any listed contraindications.

Derived from policy criteria and KDIGO/OPTN guidance

Advanced renal disease (one required): 1) End-stage renal disease (ESRD) with GFR < 15 mL/min/1.73 m2 OR 2) CKD stage 4 with GFR < 30 mL/min/1.73 m2 in members expected to reach ESRD.GFR < 15 or GFR < 30 with expectation to progress

Patients with GFR > 30 who are rapidly progressing should be referred for evaluation.

Absence of contraindications: No active untreated infection (except hepatitis C when managed), no uncontrolled HIV unless HIV-specific criteria met, no active high‑risk malignancy, no recent stroke or TIA within specified windows, no active symptomatic cardiac or peripheral arterial disease without appropriate evaluation/clearance, ability to adhere to post‑transplant regimen with caregiver support, no active substance use disorder affecting decision‑making, no decompensated cirrhosis unless candidate for combined liver‑kidney transplant, and no elevated anti‑GBM antibodies.

See HIV‑specific node for required HIV documentation.

HIV-specific requirements (if applicable): When HIV infection is present, all of the following must be documented: CD4 cell count > 200 cells/mm3; absence of active AIDS‑defining opportunistic infection; and member is currently on effective antiretroviral therapy (ART).CD4 > 200

These conditions allow consideration of transplant in virologically/immunologically controlled HIV.

Candidate selection

Candidates must meet disease severity and contraindication rules:

Age: Member is pediatric (age < 18 years).

Renal disease severity: ESRD with GFR < 15 mL/min/1.73 m2 OR CKD stage 4 with GFR < 30 mL/min/1.73 m2 in members expected to reach ESRD.GFR thresholds

Referral for transplant evaluation should be considered for rapidly progressing patients even if GFR > 30.

Contraindications absent: Does not have any contraindications listed in policy, including: active untreated infection (except managed hepatitis C), HIV without meeting HIV‑specific criteria, active high‑risk malignancy, stroke within past 6 months or TIA within past 3 months, active symptomatic cardiac disease without cardiology evaluation/clearance (cardiology clearance required after MI), active symptomatic peripheral arterial disease not managed, inability to adhere to regimen despite caregiver support, active substance use disorder affecting decision‑making, decompensated cirrhosis unless for combined transplant, and elevated anti‑GBM antibodies.

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.

Documentation Required

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

Required Evaluation and Pre-Transplant Assessment

Prior Authorization

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

Documentation Required

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).

Provider Requirements, Prior Authorization, and Billing Guidance

Prior Authorization

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.

50300, 50320, 50323, 50325, 50327, 50328, 50329, 50360, 50365, 50547
HCPCS S2152 (global transplant/procurement/transplant‑related services)

Step Therapy

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

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

Note

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
