Official Description

Ambulatory blood pressure monitoring, utilizing report-generating software, automated, worn continuously for 24 hours or longer; including recording, scanning analysis, interpretation and report

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Ambulatory blood pressure monitoring is a diagnostic procedure designed to assess blood pressure variations over an extended period, typically 24 hours or longer. This method is particularly useful for capturing blood pressure readings during a patient's normal daily activities, providing a more comprehensive view of their blood pressure patterns outside the clinical environment. The procedure involves the use of a portable blood pressure monitoring device, which consists of a cuff that is placed around the upper arm and a compact digital machine that can be secured to a belt. This device is programmed to automatically inflate the cuff at predetermined intervals, measure the blood pressure, and record the readings. The continuous monitoring helps to identify potential issues such as white coat hypertension, where a patient's blood pressure may be elevated in a clinical setting due to anxiety, or nocturnal hypertension, where blood pressure remains high during sleep. Additionally, it allows healthcare providers to evaluate the effectiveness of antihypertensive medications by observing how blood pressure responds throughout the day and night. At the conclusion of the monitoring period, the device is returned to the healthcare provider, who utilizes report-generating software to analyze the collected data, interpret the results, and produce a comprehensive report. This report is essential for making informed decisions regarding the patient's treatment plan and ongoing management of their blood pressure.

1. Indications

Ambulatory blood pressure monitoring is indicated for several clinical scenarios, including:

  • Assessment of Hypertension: To evaluate patients with suspected hypertension or those with previously diagnosed hypertension to monitor blood pressure fluctuations throughout the day and night.
  • White Coat Hypertension: To determine if a patient experiences elevated blood pressure readings in a clinical setting due to anxiety, which may not reflect their true blood pressure levels in everyday life.
  • Nocturnal Hypertension: To assess blood pressure levels during sleep, identifying patients who may have elevated blood pressure at night, which can be a risk factor for cardiovascular events.
  • Medication Efficacy: To evaluate the effectiveness of antihypertensive medications by monitoring blood pressure responses to treatment over a continuous period.

2. Procedure

The procedure for ambulatory blood pressure monitoring involves several key steps:

  • Device Setup: The healthcare provider prepares the ambulatory blood pressure monitoring device, which includes a cuff and a digital recording unit. The cuff is fitted around the patient's upper arm, ensuring a snug but comfortable fit to obtain accurate readings.
  • Programming the Device: The device is programmed to take blood pressure measurements at regular intervals, typically every 15 to 30 minutes during the day and less frequently at night, depending on the specific protocol established by the healthcare provider.
  • Patient Instructions: The patient is instructed on how to wear the device, including guidance on daily activities to avoid interference with the monitoring process. They are advised to maintain their normal routine while wearing the device to ensure accurate data collection.
  • Monitoring Period: The patient wears the device continuously for the prescribed duration, which is usually 24 hours or longer. During this time, the device automatically inflates the cuff, records blood pressure readings, and stores the data for later analysis.
  • Device Return: After the monitoring period is complete, the patient returns the device to the healthcare provider. The provider then downloads the recorded data from the device for further analysis.
  • Data Analysis and Reporting: The healthcare provider utilizes report-generating software to analyze the collected blood pressure data, interpret the results, and create a comprehensive report detailing the patient's blood pressure patterns over the monitoring period.

3. Post-Procedure

After the ambulatory blood pressure monitoring procedure, the patient may resume normal activities immediately. The healthcare provider will review the generated report, which includes detailed information on blood pressure readings, variability, and any identified patterns. Based on the findings, the provider may discuss potential adjustments to the patient's treatment plan, including medication changes or lifestyle modifications. Follow-up appointments may be scheduled to further evaluate the patient's blood pressure management and overall cardiovascular health.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
GA Waiver of liability statement issued as required by payer policy, individual case
GZ Item or service expected to be denied as not reasonable and necessary
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
95 Synchronous telemedicine service rendered via a real-time interactive audio and video telecommunications system: synchronous telemedicine service is defined as a real-time interaction between a physician or other qualified health care professional and a patient who is located at a distant site from the physician or other qualified health care professional. the totality of the communication of information exchanged between the physician or other qualified health care professional and the patient during the course of the synchronous telemedicine service must be of an amount and nature that would be sufficient to meet the key components and/or requirements of the same service when rendered via a face-to-face interaction. modifier 95 may only be appended to the services listed in appendix p. appendix p is the list of cpt codes for services that are typically performed face-to-face, but may be rendered via a real-time (synchronous) interactive audio and video telecommunications system.
