Coetzer was named in the 15-man squad yesterday after recovering from a wrist injury which kept him out of the recent ICC World Cricket League and Intercontinental Cup fixtures against Ireland.
"I'm really excited about the challenges that lie ahead," Coetzer said. "This is an opportunity to show the character of this squad."
The squad includes seven centrally contracted players including Scotland's leading one-day international wicket-taker, Majid Haq.
Matt Machan, who was recently named Sussex young player of the year, will also make the journey to Dubai, along with wicketkeeper David Murphy who played a significant role in guiding Northamptonshire to the Friends Life t20 title as well as promotion to the LV= County Championship first division.
Also named are two of Scotland's emerging young talents, Michael Leask and Matthew Cross. Freddie Coleman is unable to make the tour due to university studies, while work commitments kept Calvin Burnett out of contention for selection.
Scotland will prepare with a 12-day tour to Sri Lanka before two warm-up games against the United States and Namibia in Dubai. They begin their qualification campaign against Bermuda on November 15. Six teams will qualify for next year's World Twenty20, which will be held in Bangladesh from March 16.
