You can try, but our general experience is that anybody who tries to handle their case with the insurance company never comes out ahead on that. Their job is to minimize your climb and to pay you as little of an amount as possible, so they will use everything they can use against you.
Just remember, that’s how they’re being paid, that’s what they’re paid to do, that’s their job, to pay out as little as possible. They’re probably going to get a bonus at the end of the year based on how little the money they can pay out. So generally it’s not a good idea to try to handle your own client.
