Background and objectives New childhood cancer diagnoses require timely, complex care coordination and cause considerable logistic burden for families. We used renal tumors as a model to examine healthcare utilization and cost following new solid tumor diagnosis. Methods Children (ages 0–21) with International Classification of Disease (ICD) codes for renal malignancy and subsequent nephrectomy were identified from North Carolina Medicaid claims data (2014–2020). We stratified patients by duration of follow‐up, then quantified healthcare utilization and billing totals. Results Eighty‐one children met study criteria. Median age at diagnosis was 3 years (interquartile range [IQR]: 1–5). Median family monthly earned income was $0. One month following diagnosis, children cumulatively spent a median of 16 days receiving medical care (IQR: 10–20), 28 days at 3 months (IQR: 21–43), and 50.5 days at 1 year (IQR: 35–94.5). Children cumulatively spent a median 12 days as inpatients during the first 3 months (IQR: 7–17) and 13.5 days at 1 year (IQR: 8.5–37). Children cumulatively completed a median 12 outpatient encounters at 3 months (IQR: 7–17) and 26 at 1 year (IQR: 12–36). At 1 year, median Medicaid claim reimbursements for children with renal malignancy was $50,041 (IQR: $36,670–$80,734). Conclusion In examining healthcare utilization in children with renal tumor diagnoses, the substantial number of days spent in medical facilities greatly impacts the burden of care on families, especially for those with limited financial resources. Awareness of this logistic strain on families and careful planning to consolidate patient visits may improve the navigability of pediatric cancer regimens for families, particularly those with limited resources.
