Objectives: This cross-sectional study compared the healthcare expenditures associated with multimorbidity (having ≥2 chronic conditions) versus no multimorbidity among older United States (US) adults (aged ≥ 50 years) with self-reported pain in the past 4 weeks. Methods: This research used data from the 2018 Medical Expenditure Panel Survey. Adjusted linear regression models evaluated group differences in various annual healthcare expenditures. Results: Descriptive statistics indicated multimorbidity was associated with all personal characteristics (p < 0.05) except gender and smoking status (p > 0.05). Multimorbidity had 75.8% greater annual total health expenditures (p = 0.0083), 40.6% greater office-based expenditures (p = 0.0224), 100.6% greater prescription medication costs, (p = 0.0268), yet 47.3% lower inpatient expenditures (p = 0.0158), and 56.6% lower home healthcare expenditures (p < 0.0001) than no multimorbidity. Discussion: This study found greater healthcare expenditures among older US adults with pain and multimorbidity, which captures the financial burden of comorbidity in this population.
