ob coding situation

have a patient that is 37 weeks that started contorted and is dilated to a 5 and then labor stopped. Patient is being induced. In the hospital patients cannot be induced unless they are 39 weeks. LD has asked the obgyn what code he would use because the patient is not 39 weeks and he is doing and inductions. Can someone help me with a code for explaining the cervix stopped dilation that will explain the inductions?

Thank you
