The British doubles specialist has missed the whole season after being diagnosed with Hodgkin's lymphoma, a form of cancer, last December.
Hutchins underwent six months of chemotherapy at the Royal Marsden Hospital and was told he was in remission in July.
The 28-year-old returned to training immediately and he and Fleming, who has been playing with former Wimbledon champion Jonny Marray this year, will resume their partnership at the start of next season.
Hutchins told The Tennis Space: "I could play earlier but the plan is to return at the start of next year. One of the first things Colin said to me was, 'I'm going to be waiting for you, we've got unfinished business.'
"There's a long way to go with our careers and our partnership. We don't want to chop and change and play with other partners. We're a team who want to play together and we really feel as though we can push up the world rankings.
"We really want to push on and win a slam. That's really where we want to be, and that's our goal for the next few years.
"My ambitions haven't changed. When you're away from tennis, you have a lot of time to reassess your game. But I've always been a very ambitious person, I've always believed that we can get to the top of the rankings and be the number one team in the world."
Hutchins has stayed involved with tennis, organising a charity event at Queen's Club in June to raise money for the Royal Marsden and helping out as an analyst for the Davis Cup team.
He knows it will be a big moment when he plays a competitive match again, and he said: "I imagine it will be very emotional when we play again together.
"We've talked about it a lot this year. Not playing for a while has almost improved our understanding of each other and how we can get better as a team and benefit from each other's strengths.
"I've spoken very openly about my life and my illness and everything, and we've been very open with other, and that makes it easier when we talk about what we have been struggling with and what we need to work on."
