Objectives: To estimate payments for the treatment of COVID-19 compared with that of influenza or viral pneumonia (IP), from the perspective of the US payer.
Study design: Retrospective cohort analysis.
Methods: Patients with COVID-19 during the period from October 1, 2020, to February 1, 2021, or IP during the period from October 1, 2018, to February 1, 2019, in the IBM MarketScan databases were identified. The index was defined as the date of the first COVID-19 or IP diagnosis. Patients with COVID-19 were stratified by severity. Variables for all patients included demographics and comorbidities at the time of index and duration of disease. IP and COVID-19 cohorts were matched using propensity scores, and inflation-adjusted all-cause payments (ACP), and disease-specific payments (DSP) for IP vs COVID-19 were estimated using generalized linear models.
Results: Matched cohorts included 6332 Medicare (female, 58.5%; mean [SD] age, 75.3 [7.6] years), and 397,532 commercially insured patients (female, 57.6%; mean [SD] age, 34.7 [16.7] years). ACP and DSP were significantly higher in the COVID-19 cohort vs IP cohort. Payments for severe/critical COVID-19 were significantly greater than those for IP, with adjusted marginal incremental DSP and ACP of $24,852 (95% CI, $21,573-$28,132) and $50,325 (95% CI, $43,932-$56,718), respectively. IP was significantly less expensive than moderate COVID-19 for commercial payers but not Medicare. IP was more expensive than mild COVID-19 for all payers.
Conclusions: Payments associated with severe/critical COVID-19 significantly exceeded those associated with IP. For Medicare, IP was more expensive than mild or moderate COVID-19. For commercial payers, IP was less expensive than moderate COVID-19 but more expensive than mild COVID-19.
