You are really not providing sufficient facts for a response. However, generally if there is a judgment against your husband then yes wages can be garnished consistent with Florida's statute and subject to its limitations and exemptions.
To garnish wages, a creditor must usually have a court judgment. In many states, a husband is responsible for his spouse's medical debts, and a man is responsible to pay the cost of the birth of his child.
I always like to point out that when you took your wedding vows, you said you took each other "for richer, for poorer, in sickness & in health. Most states interpret that vow to mean that spouses must pay for each others medical bills, even if they didn't agree to them & even if they didn't know about them.
Hope this perspective helps!
This is a significant amount of money and merits seeing an attorney for a brief conference at least. You have not really provided sufficient facts to properly answer the general question but you may have a lot of defenses and arguments as to why you should not owe that amount of money over and above the insurance.
