The Republic of Ireland's contract is due to expire in the summer and so far the two parties have been unable to reach an agreement over fresh terms.
Despite admitting that sitting on the West Brom bench for large parts of the season has been "horrible", the 24-year-old has not ruled out the possibility of remaining at the Hawthorns.
"Apart from throughout January, when I played four or five games on the bounce, it has been horrible," said Cox. "You have just got to stick with it and now we have reached 40 points, hopefully I can get a bit more game time.
"We will sit down and discuss it. The club have the option to take up a further year of my contract at the end of this season.
"For me it is about waiting for the end of the season to come, waiting for the Euros and seeing if I am picked in the Ireland squad. If I am, I'll go out there and see what I can do and then see what the club's decision is. I'll see whether they want to keep me or whether I move on."
Cox joined the Baggies in 2009 from Swindon Town.
