The results are recorded, scanned, analyzed, interpreted, and reported by the healthcare provider. This procedure is typically performed to assess blood pressure patterns and rule out white coat hypertension.

2. Official Description

The official description of CPT code 93784 is: ‘Ambulatory blood pressure monitoring, utilizing report-generating software, automated, worn continuously for 24 hours or longer; including recording, scanning analysis, interpretation, and report.’

3. Procedure

1. The healthcare provider or a technician fits the patient with an ambulatory blood pressure monitor.
2. The patient wears the device continuously for 24 hours or more while performing their daily activities.
3. The device automatically records blood pressure readings at regular intervals and stores the data.
4. The healthcare provider or a technician scans the recorded data and generates a report.
5. The healthcare provider reviews the scanning analysis, interprets the information in conjunction with the patient’s medical history and reported activities, and reports their findings.

4. Qualifying circumstances

Ambulatory blood pressure monitoring using CPT 93784 is typically performed for patients with suspected white coat hypertension, where blood pressure readings are higher in a healthcare setting but normal at home.

• Prescription for ambulatory blood pressure monitoring
• Date and duration of the monitoring period
• Scanned data and analysis of blood pressure readings
