Generally speaking, you are entitled to temporary disability benefits while you cannot work from a work injury. This is ongoing until the doctor declares you have reached Maximum Medical Improvement. That means you've reached a point in your medical treatment where you've acheived full recovery, or you're not going to get better or worse and what is left is permanent disability. If you have perm disability left, that will be worth additional benefits. You should also have future medical care to control any flare-ups from this injury. in some instances, you may be entitled vocation retraining if your permanent disability prevents you from returning to your prior job.
In your scenario, it sounds like you are definitely not Max Med Imp (MMI). Since your employer closed up shop, I would think that the work comp adjuster is being unreasonable in cutting off your temp disability. I'm not positive because it depends on what State you're in. Regardless, virtually every work comp system is set up to give the injured worker the benefit of the doubt.
Call your adjuster to find out what is going on and feel free to ask them all your questions. Be sure to ask all the questions you need to ask so you can understand what is going on, especially the question about why you stopped getting temp disability checks.
Second source, check online to find out what state agency govern all work comp issues in your state and call them to find out what your rights are. You can double check what your adjuster told you with what this person tells you.
Last resort, consult with an attorney (or if this is too much for you, then this is probably your first resort). Do some research on this. Work comp attorneys get paid based on how much your permanent disability and future medical care gets settled for (in California it's 15%) no matter how much work they do to get to that point. There are some firms out there referred to as "mills". They just get injured workers in and out as soon as possible to get that payout. It makes their motives questionnable.
