I often see when people sneeze, the colleagues suddenly respond with the word "Gesundheit".
My question is that, can we use "Gesundheit" when somebody is coughing? If not, is there any word for it?

No, not specific for coughing.
There is neither a word for it nor is it common practice for bystanders to comment any coughing, only in case you are really concerned about the cougher's condition.
As you figured out, a bystander's commit is usual for sneezing.
A current (last 10-20 years) "developement" of "Gesundheit!" from bystanders turns into "Entschuldigung." from the sneezer in business environment = where you disturb an unknown crowd, while being with friends, the "Gesundheit! - Danke." is common.
So you could derive a "Entschuldigung." as well from the cougher because he might have disturbed the bystanders.

As far as I'm aware, the word "Gesundheit" is only used when people sneeze. It's similar to "bless you" in English.
One explanation I heard is that it is possible to sneeze for unrelated reasons (binding light, dust in the nose), and expresses the wish that the person sneezing should be healthy.
I never heard of a word in response to coughing, neither German nor English.
"Gesundheit" is only used when someone sneezes
It's supposed to be a custom from the days of the Black Death in Europe. The "Knigge" , which is widely considered the reference for questions regarding good manners in Germany, claims that you should no longer use this expression (and politely pretend to have seen and heard nothing). However, this rule didn't prevail (yet?) and people continue to wish others "health" when they sneeze.
As an addition to Shegit's answer, if you hear someone saying "Gesundheit" as a reaction to coughing, it is most likely that this person mistook the coughing for a sneeze (or is not sure what it was)
For completeness, if someone says something totally not understandable, like using a lot of technical vocabulary, some people say "Gesundheit" sarcastically to point out that you spoke so unclearly or that the word sounds so complicated that you might as well just have sneezed.
