CPT codes for Cardiovascular medical billing

Blood flows through a network of vessels throughout the body, supplying oxygen and nutrients to specific cells and assisting in the elimination of metabolic wastes. The heart circulates blood in and out of the blood arteries.

Below are the most commonly used CPT codes for Cardiovascular medical billing:

  • CABG:

CABG also known as coronary artery bypass graft surgery or bypass surgery. It’s a surgical procedure to restore normal blood flow to an obstructed coronary artery.

PICC line is a catheter placed into a superficial, smaller vein. It can be placed in veins in the Basilic and Cephalic vein.

Central Line

A central venous catheter or central line is a catheter placed into a large vein. It can be inserted into neck veins, the Internal Jugular vein, the chest, the Subclavian or Anxillary vein, the groin, or the femoral vein.

  • Pacemaker and Defibrillator:

A pacemaker stimulates the heart to beat normally using electrical pulses. Pacemakers are used to treat rhythms that are too slow, fast, or irregular.

CPT Codes for Cardiovascular Medical Billing

Arrhythmias is the term used for abnormal heart rhythms.

Defibrillators An ICD (Implantable Cardioverter Defibrillator) monitors heart rhythms. Shocks are delivered if dangerous rhythms are sensed, it delivers. An ICD can help control life-threatening arrhythmias, especially those that can cause sudden cardiac arrest.

  • Angioplasty and stent placement

Angioplasty is a technique that widens or unblocks the blood arteries that supply the heart.

The stent is a small, metal mesh tube that expands inside a coronary artery. A stent is frequently inserted during or immediately following angioplasty. It aids in preventing the artery from contracting again.

Iliac artery

Tibial / Peroneal

  • Thoracic aortic aneurysm repair

To repair a thoracic aortic aneurysm with open chest surgery, the damaged part of the aorta is removed and replaced with a synthetic tube (transplant) that is sewed into place.
