CPT® Code 93786

Ambulatory blood pressure monitoring, utilizing report-generating software, automated, worn continuously for 24 hours or longer; recording only

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, which can provide insights into their blood pressure behavior outside of a clinical environment. The procedure involves the use of a portable blood pressure monitoring device that is worn continuously, allowing for the collection of data at regular intervals. This continuous monitoring can help identify conditions such as white coat hypertension, where a patient's blood pressure may be elevated in a clinical setting due to anxiety, as well as nocturnal hypertension, which refers to elevated blood pressure during sleep. Additionally, it can evaluate the effectiveness of antihypertensive medications by monitoring how well they control blood pressure throughout the day and night. The device consists of a blood pressure cuff that is placed around the upper arm and a compact digital monitor that can be secured to a belt. The monitor is programmed to automatically inflate the cuff, measure the blood pressure, and record the readings at specified intervals. After the monitoring period, the device is returned to the healthcare provider, who utilizes report-generating software to analyze the collected data. It is important to note that specific CPT® codes are designated for different aspects of this procedure: code 93784 is used when recording, scanning analysis, and interpretation with a report are performed; code 93786 is for recording only; code 93788 is for scanning analysis and report only; and code 93790 is for a review of the procedure with interpretation and report.
