Teladoc Health (NYSE: TDOC), a leader in the growing field of telemedicine, reported its first-quarter results on Tuesday. Revenue continues to grow at a brisk pace thanks to strong membership gains and increasing utilization rates. On the downside, Teladoc's net loss expanded during the quarter thanks to rising costs.

International subscription revenue more than doubled to $30 million. Consolidated visit-fee revenue grew 26% to $22.6 million. The bulk of the gains were driven by growth in U.S. paid visits. Organic revenue growth, which strips out the effects of acquisitions, was 23%. Total revenue of $128.6 million came in at the high end of management's guidance range. Gross margin declined by 470 basis points to 65.3%. The decline is attributable to the mix of revenue and the effect of acquisitions. Cash balance at quarter end was $480 million. Total debt was $563 million. Per member per month (PMPM) fees, which are paid to Teladoc each month by insurers, grew 3% to $1.03 when compared with the year-ago period. Management was quick to point out that this number is weighed down by the effect of acquisitions since it takes time for acquired members to grow comfortable using telemedicine services. Teladoc also acquired MedecinDirect during the quarter. This company, based in Paris, expands Teladoc's footprint in Europe. The company also stated that the go-live date for its recently announced Teladoc Telemedicine Services in Canada is scheduled for the third quarter of 2019. Looking beyond the financials, Teladoc's membership and usage numbers showed that the company continues to make good progress with adoption: U.S. paid membership grew 28% to 26.7 million. On an organic basis, U.S. paid membership growth would have been 23%. U.S. visit-fee-only access, which are consumers with access to Teladoc's network who are not fully covered by insurers, grew 7% to 10.2 million. Total global visits grew 75% to 1.06 million.

Our growth of over 3 million paid members in Q1 2019 through the health-plan channel is proof of our continued success.
