The Action Comics and Superman: World of New Krypton writer revealed his plans on his spotlight panel at San Francisco's WonderCon, reports Robot 6.
He said that he had been unable to agree with the publisher over certain decisions but is not leaving DC on bad terms.
Rucka's exclusive contract with the publisher ended three years ago, though he continued working only for DC until recently.
The announcement has led to some uncertainty about the future of the Batwoman title that was planned to spin out of Rucka and JH Williams III's recent run on Detective Comics.
Williams admitted uncertainty about the future of the title on his blog, but assured fans that DC would not be dropping the character.
"I was afraid something like this was going to occur but held out hope that it wouldn’t happen," Williams wrote. "That DC and Greg could come to some sort of agreement, apparently not going to happen.
"So what does this mean for Batwoman and the project I've spent a decent amount of time and thought on? I don’t know. I do know that DC is firmly committed to this character from what I hear from them. So where does all of this leave us?
"I believe DC will want the character to continue somehow. In what form? I'm not sure, but she'll be back, I'm sure of it. This character has too much potential to just go by the wayside. So we should be hearing some sort of news at the appropriate time I assume."
Rucka said that he intends to continue working with Williams.
