B-Natriuretic Peptide
Policy Number: MP-142
Latest Review Date: August 2024
Category: Laboratory
POLICY:
The measurement of plasma brain natriuretic peptide (BNP) or N-terminal proBNP (NT-proBNP) may be considered medically necessary for any of the following indications:
- Diagnosis of heart failure in a patient with dyspnea; OR
- Differentiating dyspnea due to heart failure from pulmonary disease, especially when the etiology of dyspnea is unclear; OR
- Establishing a prognosis or disease severity in patients diagnosed with chronic heart failure; OR
- Monitoring response to treatment for heart failure to achieve optimal dosing of guideline directed medical therapy
Plasma brain natriuretic peptide (BNP) or N-terminal proBNP (NT-proBNP) testing is considered investigational for all other indications, including risk assessment.
DESCRIPTION OF PROCEDURE OR SERVICE:
Brain natriuretic peptide (BNP) is a 32-amino acid polypeptide cardiac neurohormone. It is secreted by the ventricles of the heart in response to volume expansion and pressure overload. The peptide was first isolated from a porcine brain in 1988 and later from the cardiac ventricles of porcine, rat and humans. BNP is biologically active as a hormone. N-terminal proBNP (NT-proBNP) is cleared passively from the body and is not biologically active. Both will show elevated levels in the presence of heart failure. The half‐life of BNP is much shorter than NT‐proBNP, which explains why NT‐proBNP serum values are higher than BNP values, even though both molecules are released in equimolar proportions.
Although kidney failure, pulmonary embolism, pulmonary hypertension, sepsis, and lung problems can cause high BNP levels, the most widely investigated use for BNP has been in heart failure. BNP release appears to be in direct response to ventricular volume stretch and pressure overload. Measurement of BNP is a highly sensitive and moderately specific method of differentiating heart failure from other non-cardiac causes of dyspnea. BNP testing is often performed in the emergency room when there is suspicion of heart failure so treatment can be started as soon as possible.
KEY POINTS:
This policy has been updated with literature review performed through August 1, 2024.
Summary of Evidence
When combined with other clinical information, BNP and NT-proBNP levels are useful in establishing or excluding the diagnosis of congestive heart failure in patients with acute dyspnea. Another clinically significant use of BNP and NT-proBNP measurement is when used in the presence of acute coronary syndrome. Patients can be identified as at high and low risk for adverse outcomes so treatment should be adjusted accordingly. The evidence is sufficient to support that the technology, when used for the purposes of diagnosis and evaluation of congestive heart failure as defined in this evidence review, results in an improvement in net health outcomes.
BNP and NT-proBNP concentrations can be skewed in patients who suffer from comorbidities including diabetes, renal failure, obesity, coronary artery disease, valvular heart disease, pulmonary hypertension, and sepsis. The value of measuring natriuretic peptides in this population cannot be proven beneficial and medically necessary. A biological variation of BNP should not be interpreted strictly as there is random fluctuation noted and the results should not be directly transferred into clinical practice. More accurate studies are needed to prove the utility of this technology at this time to support the measurement of plasma brain natriuretic peptide (BNP) or N-terminal proBNP (NT-proBNP) in risk stratification. The evidence is insufficient to support that the technology results in an improvement in net health outcomes when used for risk stratification.
Practice Guidelines and Position Statements
American College of Cardiology Foundation (ACCF)/American Heart Association (AHA)
Guidelines from the American College of Cardiology Foundation (ACCF) and the American Heart Association (AHA) list, as a class I recommendation, the use of BNP or NT-proBNP values in the diagnosis of heart failure in ambulatory patients with dyspnea, especially when the diagnosis is uncertain, as well as their use in establishing the prognosis or disease severity in ambulatory patients with chronic heart failure. The guidelines assign a class IIa recommendation to the use of BNP or NT-proBNP in determining optimal dosing for select ambulatory patients who are clinically euvolemic and are undergoing medical therapy in a well-structured heart-failure management program.
For hospitalized/acute patients, the ACCF/AHA guidelines list as a class I recommendation the use of BNP or NT-proBNP in the diagnosis of acutely decompensated heart failure, especially when the diagnosis is uncertain, as well as the use of BNP or NT-proBNP and/or cardiac troponin in establishing the prognosis or disease severity of acutely decompensated heart failure in such patients. However, the guidelines state that the usefulness of BNP or NT-proBNP in guiding therapy in hospitalized/acute patients with acutely decompensated heart failure has not been well established.

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.
