Current understanding of medical debt among various income ranges and insurance carriers is limited. We analyzed median household incomes, insurance carriers, and medical debt of plastic surgery patients at a major metropolitan children's hospital. A retrospective chart review for zip codes, insurance carriers, and account balances was conducted for 2018-2021. All patients were seen by members of the Division of Pediatric Plastic Surgery at Ann and Robert H. Lurie Children's Hospital of Chicago. Blue Cross was reported separately among other commercial insurance carriers by the hospital's business analytics department. Median household income by zip code was obtained. IBM SPSS Statistics was used to perform chi-squared tests to study the distribution of unpaid account balances by income ranges and insurance carriers. Of the 6877 patients, 630 had unpaid account balances. Significant differences in unpaid account balances existed among twelve insurance classes (P < 0.001). There were significant differences among unpaid account balances when further examined by median household income ranges for Blue Cross (P < 0.001) and other commercial insurance carriers (P < 0.001). Although patients with insurance policies requiring higher out-of-pocket costs (ie, Blue Cross and other commercial insurance carriers) are generally characterized by higher household incomes, these patients were found to have higher unpaid account balances than patients with public insurance policies. This suggests that income alone is not predictive of unpaid medical debt and provides greater appreciation of lower income families who may make a more consistent effort in repaying their medical debt.
