While Asian Americans experience disparate access to health services, little is known about the extent to which providers discriminate against Asian American patients. Further, research on Asian American health disparities tends to group Asian American ethnicities together, overlooking potential within-group differences. We deployed a field experiment to assess whether Asian American ethnic sub-groups experience discrimination in appointment scheduling. We further explored the impact of racial concordance between Asian patients and physicians. Overall, we did not detect significant differences in appointment offer rates between White and Asian American patients. However, we found that Asian Americans experienced longer wait times driven primarily by the treatment of patients of Chinese and Korean descent. Physician offices, surprisingly, offered concordant Asian patients appointments at significantly lower rates. The disparities Asian Americans experience relative to White Americans through longer waits for primary care appointments are not consistent across sub-groups. Increased attention to the unique experiences of people of Asian descent in accessing health services is warranted.
