  Abstract: How has the increase in synchronous telemedicine services throughout the COVID-19 pandemic impacted patient health outcomes? Using 2018-2022q1 claims data from Optum’s de-identified Clinformatics®️ Data Mart Database, I examine differences in telehealth and face-to-face care for office and outpatient evaluation and management (E/M) service claims, where telehealth coding has been the most frequent. Telehealth usage is associated with higher likelihood of patient mortality and ER visit within 6 months of E/M service claim, where I find an average effect of 5 additional deaths and 13 additional ER visits per 1,000 patients in the post-March 2020 period. To explain observed differences in health outcomes across visit modalities, I model the physician-patient interaction as a costly information acquisition problem, where rationally inattentive physicians learn about the patient’s health status through costly signals. Estimated increases in information costs with telehealth usage range between 5 to 29 percent on average after March 2020. These findings quantify the consequences of using telehealth as a substitute for in-person care.
