If you are determined partially disabled by a Workman's Compensation physician can you also collect disability insurance?

It would depend on your disability insurance plan. Some plans exclude work-related disabilities. If your plan excludes work-related disabilities, then you would initially be denied through your disability insurance. You should still file a claim with them however. If your Worker's Compensation claim ends up being denied though, you could then forward a copy of the denial letter to your disability insurance carrier for review of possible approval. If your plan does not exclude work-related disabilities, then you would be able to file both claims. You would just want to make sure that when filing, each carrier knew about the other. Keep in mind, the benefit you receive through Worker's Compensation will be a direct offset to the benefit provided by the disability insurance.
