Out-of-pocket cost by cancer stage at diagnosis in commercially insured patients in the United States

Abstract

AimsOut-of-pocket (OOP) costs may constitute a substantial financial burden to patients diagnosed with cancer. Earlier stage diagnosis and treatment of cancers may promote decreased morbidity and mortality, subsequently also lowering costs. To better understand costs experienced by patients with cancer, OOP costs by stage post-diagnosis were estimated.Materials and methodsA retrospective analysis was conducted using Optum’s de-identified Integrated Claims-Clinical dataset with Enriched Oncology, which includes data from commercially insured members (June 1, 2015–July 31, 2020). Mean annual and cumulative OOP costs (co-pay + co-insurance + deductible) (2020 USD) were reported through a 3-year period post-cancer diagnosis among adult commercially insured members (not including Medicare Advantage members) diagnosed with staged breast, cervical, colorectal, lung, ovarian, or prostate cancer between January 1, 2016 and June 30, 2020 with continuous enrollment for ≥1-month post-diagnosis.ResultsA total of 7,494 eligible members were identified who were diagnosed with breast, cervical, colorectal, lung, ovarian, or prostate cancer. A greater proportion of OOP costs were incurred in year 1 post-diagnosis but remained relatively high through year 3 post-diagnosis. Cumulative mean OOP costs were as high as $35,243 (lung stage IV) per commercially insured patient by year 3 post-diagnosis and were generally higher among those diagnosed at later stages (III/IV) than those diagnosed at earlier stages (I/II) across all cancers.LimitationsGeneralizability of these results is limited to those with commercial health insurance coverage. Additionally, cancer staging was dependent on accuracy of staging as recorded in the electronic medical record and as determined by Optum’s proprietary algorithm using natural language processing.ConclusionCumulative mean OOP costs among commercially insured patients during the 3-year period post-cancer diagnosis were substantial and generally higher among those with later stage cancer diagnoses. Diagnosis of cancer at earlier stages may allow for more timely treatment and lessen patient OOP costs.
