CPT® Code 76818

A fetal biophysical profile (BPP) is a comprehensive assessment performed during pregnancy to evaluate the well-being of the fetus. This procedure utilizes ultrasound imaging to measure several critical parameters, including the volume of amniotic fluid, fetal breathing movements, gross body movements, and fetal muscle tone. The BPP is particularly significant as it aids in predicting the presence or absence of fetal asphyxia, which is a condition that can lead to inadequate oxygen supply to the fetus, and it also assesses the risk of fetal death during the antenatal period. The procedure is typically conducted when the mother presents with a full bladder, which enhances the clarity of the ultrasound images. During the examination, an acoustic coupling gel is applied to the skin of the lower abdomen to facilitate the transmission of ultrasound waves. A transducer is then placed against the skin and moved back and forth to locate the fetus and assess cardiac activity. Additionally, the position of the placenta may be noted during this general examination. Following this initial assessment, the ultrasound is used to evaluate the amniotic fluid volume, observe gross fetal movements and tone, and assess fetal breathing movements. A non-stress test (NST) may also be performed concurrently, which involves monitoring the fetal heart rate for a minimum of 30 minutes to gather further insights into fetal well-being. The results of the BPP are quantified into a biophysical score (BPS), which helps in determining the risk of fetal asphyxia and fetal death. The physician is responsible for reviewing the ultrasound images, interpreting the NST results, calculating the BPS, and providing a written report of the findings. The specific CPT® code 76818 is designated for instances where the BPP is performed in conjunction with the NST, while code 76819 is applicable when the BPP is conducted without the NST.
