Do the insurance company owe me the remaining money on the entire settlement price after I settled on a case with the at-fault party's insurance?

The adjuster told me that he would pay all my medical bills, but only paid part of them. The total amount of the settlement was $15,688.32 (medical + pain and suffering). He gave me a check for $9500 and told me that he would pay my medical bills. He did not pay but $4032.30 on my medical.
