The former world number one is currently suspended following a positive test for a banned substance at last year's World Championships.
He attended a hearing in Amsterdam last weekend but will have to wait for three weeks to hear its outcome. It is entirely possible that the 31-year-old could be cleared of any wrong-doing, but a two-year ban – which in all likelihood will lead to his retirement – is also a possibility.
"He is obviously not under pressure of playing tournaments but he is definitely fit," Hansen told reporters during a training session at the Juara Stadium in Bukit Kiara on Monday.
"The dateline for the Indonesian Open is next week (April 21), so the longer the BWF panel takes to make a decision, the more datelines are missed.
"So we hope there will be a good decision soon.”
Meanwhile, the BWF confirmed that 34 individual quota places will be granted for the top men's singles shuttlers by May 5, 2016.
Aside from being ranked highly, in order to be eligible to participate in the 2016 Olympic Games, all players must feature in at least three tournaments counting towards world rankings during a one-year period starting on May 4 this year.
These tournaments include the Thomas and Uber Cups, Sudirman Cup, World Championships, Super Series, Grand Prix Gold, Grand Prix, International Challenge and any other BWF-sanctioned event.
