DESCRIPTION OF PROCEDURE OR SERVICE:
A biophysical fetal profile (BPP) is an ultrasonographic assessment of fetal well-being. During the ultrasound, certain behavioral patterns associated with a healthy fetus are documented. The test has five different components, each worth two points (See table below). Indicators such as amniotic fluid volume, fetal breathing, fetal heart rate, movement, and tone are evaluated. A score of 8 or 10 is reassuring, a score of 6 is suspicious and indicates a need for further evaluation, and a score of 4 or less is ominous and indicates a need for immediate intervention. A low score may also reflect the fetus’s behavioral state during the test, such as normal sleep or sedation from maternal use of narcotics or central nervous system depressants. However, a decreasing score has been well correlated with poor outcome and with increasing degrees of fetal acidemia.
A reactive or reassuring NST is defined as one with at least two accelerations in a 20-minute period above the baseline fetal heart rate of 15 beats per minute for 15 seconds. If a reactive pattern is not present at the end of the first 20 minutes, attempts may be made to arouse the fetus. Fetal rest periods, which are reported to be 30 to 40 minutes in duration, must be excluded for the fetus to demonstrate a reactive NST. A nonreactive NST without fetal heart rate decelerations may not indicate fetal jeopardy but may be an indication for further evaluation. This evaluation may include a biophysical profile (BPP).
The modified BPP consists of the nonstress test (NST) and the amniotic fluid index. It can be just as useful for fetal surveillance in patients at increased risk for poor perinatal outcomes and small-for-gestational-age infants.
Components of the Biophysical Profile |
||
Parameter |
Normal (Score = 2) |
Abnormal (Score = 0) |
Nonstress test |
Two or more accelerations of at least 15 bpm above baseline for at least 15 sec in 20 minutes |
Fewer than 2 accelerations of sufficient height and duration in 20 minutes |
Amniotic fluid volume |
At least 1 amniotic fluid pocket greater than or equal to 2 cm in vertical pocket or AFI of 5cm |
No 2 × 2-cm pockets or AFI <5.0 |
Fetal breathing movements |
1 or more episodes of rhythmic fetal breathing movements for at least 30 sec |
Less than 30 sec of fetal breathing |
Fetal body movements |
At least 3 limb or gross body movements |
Fewer than 3 limb or body movements |
Fetal tone |
Extremities in flexion at rest and at least 1 episode of extension of the extremity or spine with return to flexion |
Extension at rest or no return to flexion after movement |
NOTE: Scoring of the latter four components is done ultrasonographically in a 30-minute observation period. A total score of 8 to 10 is reassuring, a score of 6 is suspicious, and a score of 4 or less is ominous. |

AFI, amniotic fluid index (the sum of the largest vertical pocket in each of four quadrants of the uterus). |
KEY POINTS:
A literature review was conducted through February 8, 2024.
Summary of Evidence
There are many indications for antepartum fetal surveillance. Common noninvasive tests are non-stress tests (NST) and biophysical profiles (BPP). These tests reflect conditions that are associated with increased fetal morbidity and mortality. Conditions that lead to fetal hypoxia, uteroplacental insufficiency, and death are all indications of increased fetal surveillance. No absolute protocols have been established for increased fetal surveillance, but certain practices are accepted for given maternal-fetal risks. For example, weekly antenatal testing beginning the 32nd week of gestation is often performed in women with low to moderate risk, such as those with gestational diabetes, chronic hypertension, or mild preeclampsia. For women with a higher risk of abnormal outcome, earlier and more frequent antenatal testing may be indicated. The evidence is sufficient to determine that the technology results in a meaningful improvement in the net health outcome.

Practice Guidelines and Position Statements
The American College of Obstetricians and Gynecologists
ACOG published a practice bulletin in December 2016 regarding ultrasound in pregnancy. They state that indications for specialized examinations, such as the biophysical profile, include fetal growth restriction and multifetal gestation.
In 2021, ACOG updated Practice Bulletin 229 regarding antepartum fetal surveillance.
- “In growth-restricted fetuses, umbilical artery doppler velocimetry used in conjunction with standard fetal surveillance, such as NSTs or BPPS or both, is associated with improved outcomes (level A evidence)
- Abnormal results from an NST or a modified BPP generally should be followed by additional testing with either a contraction stress test or BPP. (level B evidence)
- Initiating antepartum fetal testing no earlier than 32 0/7 weeks of gestation is appropriate for most at-risk patients. However, in pregnancies with multiple or particularly worrisome high-risk conditions (e.g. chronic hypertension with suspected fetal growth restriction), testing might begin at a gestational age when delivery would be considered for perinatal benefit.
- When the clinical condition that prompted testing persists, the test should be repeated periodically to monitor for continued fetal well-being until delivery. If the maternal medical condition is stable and test results are reassuring, tests of fetal well-being (NST, BPP, modified BPP, or CST) are typically repeated at weekly intervals; however, in the presence of certain high-risk conditions, some investigators have performed more frequent testing, although the optimal regimen has not been established (level C evidence).”
The American College of Radiology
According to the ACR, “The BPP is the mainstay of fetal well-being evaluation and consists of four parameters variably sensitive to the acute exposure of the fetus to hypoxemia….. For those at risk for fetal demise, testing strategies usually evaluate one or more of the fetal well-being parameters at least weekly. For the well-being of those fetuses at highest risk for fetal demise, testing can often occur twice weekly or even daily, from the point of postnatal viability until delivery is indicated.”

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.
This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.
The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.
As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.
The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:
1. The technology must have final approval from the appropriate government regulatory bodies;
2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;
3. The technology must improve the net health outcome;
4. The technology must be as beneficial as any established alternatives;
5. The improvement must be attainable outside the investigational setting.
Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:
1. In accordance with generally accepted standards of medical practice; and
2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and
3. Not primarily for the convenience of the patient, physician or other health care provider; and
4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
