Summary & Overview
CPT 99474: Home Blood Pressure Monitoring with Clinician Review
CPT code 99474 represents a structured remote blood pressure monitoring service in which a patient records and reports paired blood pressure readings twice daily over 30 days and a clinician collects, averages, documents, and discusses the results. This code formalizes remote blood pressure data collection and clinician review as a billable service, supporting hypertension management outside traditional office visits and increasing adoption of home monitoring nationally.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical service captured by the code, typical sites of service, and which national payers recognize the service. The publication outlines expected use cases, operational elements needed to capture the service, and common billing considerations. It also highlights benchmarks and policy context relevant to remote physiologic monitoring and hypertension care, and points to where to find additional payer-specific coverage details.
This summary is intended to inform clinicians, billing professionals, and policy staff about the clinical scope and administrative framing of CPT code 99474, enabling more consistent documentation and payer engagement for remote blood pressure management.
Billing Code Overview
CPT code 99474 describes remote blood pressure monitoring in which the patient measures blood pressure using a validated device and transmits readings to the clinician. The patient takes two readings one minute apart twice daily over a 30-day period, yielding a minimum of 12 readings. The clinician collects the readings, calculates average systolic and diastolic blood pressures, prepares a report, and discusses a treatment plan with the patient.
Service type: Remote patient monitoring / home blood pressure monitoring
Typical site of service: Patient’s home, with clinician review and report preparation occurring in an outpatient clinic or other ambulatory care setting.
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a history of treated hypertension and stage 1 chronic kidney disease is instructed to perform home blood pressure monitoring over a 30-day period using a validated upper-arm device. The patient is asked to measure blood pressure twice daily, taking two readings one minute apart each time, and to record at least 12 readings during the 30-day monitoring window. The patient transmits the readings electronically via a patient portal or brings a written log to the clinic.
During the clinical workflow, a registered nurse or medical assistant collects and imports the home blood pressure data into the electronic health record. A licensed clinician (primary care physician, cardiologist, or nurse practitioner) reviews the transmitted readings, calculates the average systolic and diastolic values, prepares a concise report documenting the measurement protocol, averaged results, and interpretation, and then discusses a treatment plan with the patient (medication adjustment, lifestyle counseling, or ongoing monitoring). The encounter may occur as an in-person visit, telephone/telehealth follow-up, or an asynchronous message when the clinician reviews the compiled report and conveys management decisions to the patient.
