Ambulatory Blood Pressure Monitoring (ABPM)

Section: Diagnostic Medical
Effective Date: November 01, 2019
Revised Date: October 09, 2019
Last Reviewed: September 26, 2019


Ambulatory blood pressure monitoring is typically done over a 24-hour period with a fully automated monitor. This provides more detailed blood pressure information than a traditional reading obtained during office visits. The greater number of readings with ABPM ameliorates the variability of single blood pressure measurements and is more representative of the circadian rhythm of blood pressure compared to the limited number obtained during an office measurement.


Ambulatory Blood Pressure Monitoring (ABPM) maybe be considered medically necessary for ANY of the following indications:


  • Suspected white coat hypertension (WCH) with no evidence of end-organ damage;
    • The physician has performed at least three blood pressure measurements at least one (1) week apart in the office; and
    • Blood pressure measurements by non-physicians (e.g., nurse, technician) in the office have been done and stage one hypertension readings have been obtained but <180/110, not requiring immediate treatment with medications; and
    • Member has repeated blood pressure measurements at home over at least one (1) month, and the diagnosis of hypertension remains in question; or
  • Resistant hypertension in individuals who are being treated with three (3) or more medications; or Hypertensive individuals with hypotensive symptoms thought to be related to antihypertensive medications or neurological symptoms; or
  • For individuals whose symptomatology (paroxysms of excessive sweating, palpitations, apprehension) suggest episodic hypertension secondary to an adrenal tumor and office blood pressure measurements are repeated normal; or
  • For evaluation of syncope or near syncope when used in conjunction with a 24 hour Holter monitor to determine whether symptoms are the direct result of an arrhythmia; or
  • To investigate blood pressure changes in individuals nocturnal angina.

ABPM may be considered medically necessary in children/adolescents greater than or equal to age five (5) in ANY of the following settings:

  • Confirming the diagnosis of hypertension including differentiating true hypertension from “white coat” hypertension:
    • When office blood pressure measurements are in the elevated blood pressure category for one (1) year or more; or
    • When blood pressure measurements fall within the Stage 1 HTN category over three (3) clinic visits at least one (1) to two (2) weeks apart; or
    • When blood pressure measurements fall within the Stage 2 HTN category twice within one (1) week; or
  • Assessing symptoms related to suspected drug-related hypotension; or
  • Drug resistant hypertension; or
  • To assess effectiveness of hypertensive treatment; or
  • Children and adolescents with ANY of the following:
    • A history of aortic coarctation; or
    • A history of low birth weight; or
    • Chronic Kidney Disease (CKD) and structural renal abnormalities; or
    • Endocrine disorders associated with hypertension (e.g. Congenital adrenal hyperplasia, familial hyperaldosteronism, etc.); or
    • Genetic syndromes associated with hypertension (e.g. neurofibromatosis, Turner syndrome, Williams syndrome, sickle cell disease, etc.); or
    • Obesity; or
    • Sleep-Disordered Breathing (SDP); or
    • Type 1 Diabetes Mellitus (T1DM); or
    • Type 2 Diabetes Mellitus (T2DM).

ABPM in children and adolescents should be used by experts in the field of pediatric nephrology and pediatric cardiology who are experienced in its use and interpretation.

ABPM for any other indication is considered experimental/investigational and therefore, non-covered, due to lack of supporting published peer reviewed literature.

ABPM is considered experimental/investigational and therefore non-covered in ANY of the following situations because the medical literature does not support its use in these conditions:

  • For blood pressure monitoring of individuals with heart failure; or
  • For blood pressure monitoring of pregnant women who do not meet any of the criteria listed above; or
  • For diagnosing malignant hypertension. Under accepted guidelines, malignant hypertension requires urgent hospital admission for appropriate investigation and treatment; or
  • For individuals with an irregular cardiac rhythm (e.g., atrial fibrillation); or
  • For monitoring normal blood pressure readings in the medical setting of individuals with documented evidence of end-organ damage (e.g., nephropathy, electrocardiographical changes, left ventricular hypertrophy, angina, myocardial infarction, cerebrovascular accident, transient ischemic attack) or cardiovascular risk factors (e.g., diabetes mellitus, smoking, hypercholesterolemia); or

ABPM for more than 24 hours is considered not medically necessary.

Non-invasive assessment of central blood pressure (e.g., SphygmoCor System) is considered experimental/investigational and therefore non-covered.  The long-term efficacy has not yet been established.

Professional Statements and Societal Positions

Screening for high blood pressure in adults: U.S. Preventive Services Task Force (USPSTF) recommendation statement. 2015.

The USPSTF found convincing evidence that ABPM is the best method for diagnosing hypertension. Elevated ambulatory systolic blood pressure was consistently and significantly associated with increased risk for fatal and nonfatal stroke and cardiovascular events, independent of office blood pressure. For these reasons, the USPSTF recommends ABPM as the reference standard for confirming the diagnosis of hypertension.
