Insulet Corp. reported much better than expected fourth quarter results, following on Dexcom Inc.’s report of earlier than expected coverage decision from CMS for its just-approved G7 continuous glucose monitor. Insulet (NASDAQ:PODD) soundly beat Wall Street’s expectations for quarterly revenue by $38 million, bringing in $332 million instead of the anticipated $332 million, driven by strong uptake of its Omnipod tubeless insulin pump.
