A fetal non-stress test (NST) 59025 is a noninvasive test performed on pregnant women in order to monitor the fetal heart rate. A nurse will listen to and record the baby’s heartbeat while the baby is resting and while the baby is moving.  Not all pregnant women require an NST. It usually takes 20 to 40 minutes to complete an NST.

Common reasons as to why this test should be performed including:

Diabetes
High blood pressure
Small baby or baby not growing properly
Less active baby
Following an amniocentesis
Past mother’s due date

NSTs are usually performed once or twice a week. Usually done on the same day as your doctor’s visit.
