If the patient is being admitted because she is going to deliver, then 644.13 is no longer appropriate since that code states "without delivery". If she is not yet 37 weeks gestation you could use 644.20 until the delivery happens, then it would be 644.21.

If the patient is at term, then you would use 650 according to the information in the ICD-9 book.
