iRhythm Technologies reported a 17% increase in revenue to $74.3 million for the first quarter of 2021, driven by Zio XT volume and Zio AT expansion. However, the gross margin decreased to 68.4% due to reduced Medicare reimbursement rates and COVID-19 pandemic related costs. The company is actively pursuing multiple paths to achieve better reimbursement rates and focusing on efficiency improvements.
Revenue increased by 17% to $74.3 million compared to Q1 2020.
Gross margin decreased to 68.4% from 74.7% in the same period last year.
Adjusted EBITDA was negative $5.2 million, an increase of $2.2 million compared to Q1 2020.

For the second quarter 2021, iRhythm expects sequential volume growth of approximately 4% over the first quarter of 2021 and OPEX to be approximately flat to first quarter 2021 with reductions in stock-based compensation and payroll taxes offset by increases in legal and consulting spending and hiring to support investments.
