Koeman has a clause in his contract that makes it easier to move to a new job, according to Marca.
The Dutch head coach played as a defender for Barcelona from 1989-1995 - making 192 appearances for the Catalan club during that period.
Affectionately nicknamed Tintin for his likeness to the cartoon character, Koeman enjoyed a prosperous stint in Spain: winning four La Liga titles and a European Cup.
The clause will allow clubs to enter negotiations with the Netherlands manager following the conclusion of next summer's European Championships.
"Agreements were reached in this regard [for Koeman to leave], but [teams] would have to pay to do so," Hoogma explained to Fox Sports.
"The success of the Dutch national team can help him, but I hope we finish this process and work together until the World Cup in Qatar," he noted.
"I hope we can work together for a long time because I think it's going very well."
However, Hoogma did admit that Koeman has always had his eye on the Barça hot seat.
"Ronald has always indicated that he wants to be a coach at Barcelona one day," he added.
"We'll see what happens."
