"I think that today we will come to a unanimous decision to send the mission chiefs back to Athens. My point of view is that we should do that," Moscovici told reporters ahead of the Eurogroup meeting among the eurozone's finance ministers.
He argued that the review should be concluded "as soon as possible."
"This is the political decision that must be, in my view, taken today," the commissioner stressed.
The Greek economy has been severely strained for several years, because of the country’s multibillion debt accumulated after the 2008 world economic crisis.
Greece's main lenders, which include the International Monetary Fund (IMF), the European Central Bank (ECB) and eurozone nations, signed an agreement with Athens in the summer of 2015, approving a third bailout package worth about 86 billion euros ($97 billion at current exchange rate) in exchange for highly unpopular austerity reforms such as pension cuts and tax hikes.
Under two previous bailout programs, the last of which expired on June 30, 2015, Greece received about $270 billion from the IMF, the ECB and eurozone countries. The aid also came in exchange for austerity reforms.
The international creditors need to sign off on a review of the reforms before any further aid can be released to Greece.
