Sphygmomanometer/blood pressure apparatus with cuff and stethoscope

HCPCS code

Name of the Procedure:

Blood Pressure Measurement
Common names: Blood pressure check, BP measurement
Technical/Medical term: Sphygmomanometer usage (HCPCS code: A4660)


A blood pressure measurement is a routine procedure that determines the force of blood against the walls of your arteries. It involves using a sphygmomanometer (blood pressure apparatus), a cuff that is wrapped around your arm, and a stethoscope.


Conditions Addressed: Hypertension, hypotension, cardiovascular assessments, monitoring of chronic conditions like diabetes or kidney disease.
Goals: To diagnose, monitor, and manage blood pressure-related health issues and ensure effective treatment plans.



  • Headaches
  • Dizziness
  • Shortness of breath
  • Chest pain
  • Vision problems
  • Irregular heartbeat


  • Routine health check-ups
  • Monitoring existing hypertension or hypotension
  • Patients on medication affecting blood pressure
  • Post-surgical or critical care monitoring


Pre-procedure Instructions:

  • Avoid caffeine, exercise, and smoking 30 minutes before measurement
  • Use the restroom to empty the bladder
  • Sit quietly and relax for 5-10 minutes before the test
  • Wear a short-sleeved shirt for easy access to the upper arm

Diagnostic Tests: None required beforehand.

Procedure Description

  1. The patient sits on a chair with their back supported, legs uncrossed, and feet flat on the ground.
  2. The patient extends one arm on a flat surface at heart level.
  3. The healthcare provider wraps the cuff snugly around the upper arm.
  4. The provider inflates the cuff using a manual or automatic pump.
  5. As the cuff inflates, blood flow in the artery is momentarily halted.
  6. The provider places the stethoscope's diaphragm over the brachial artery.
  7. The air is gradually released from the cuff, and the provider listens for the first pulse sound (systolic pressure) and the last pulse sound (diastolic pressure).
  8. The measurements are recorded and interpreted.

Tools and Equipment: Sphygmomanometer, blood pressure cuff, stethoscope.
Anesthesia or Sedation: None required.


The procedure typically takes about 5-10 minutes.


Blood pressure measurements can be performed in various settings:

  • Doctor's office
  • Outpatient clinic
  • Pharmacy
  • Home using personal devices


  • General practitioners
  • Nurses
  • Medical assistants
  • Pharmacists (in some settings)

Risks and Complications

Common Risks:

  • Slight discomfort or pressure sensation from the cuff inflation. Rare Risks:
  • Bruising or soreness on the upper arm.


Expected Benefits:

  • Early detection and management of hypertension or hypotension.
  • Ongoing monitoring to adjust medications and treatment plans.
  • Insight into how lifestyle changes impact blood pressure.


Post-Procedure Care:

  • No special care required, normal activities can be resumed immediately. Recovery Time: Not applicable.


Other Options:

  • Ambulatory blood pressure monitoring
  • Home blood pressure monitoring with automated devices. Pros and Cons:
  • Ambulatory monitoring provides continuous readings over 24-48 hours but requires specialized equipment.
  • Home monitoring can offer frequent data points but requires patient training and adherence.

Patient Experience

During the Procedure: Patients may feel a tight squeezing sensation on their arm, which subsides quickly.
Post-Procedure: Typically, there is no pain or discomfort. If any soreness or bruising occurs, it resolves within a day or two. Pain management is generally unnecessary.
