What CABG ICD codes can I use?

There are quite a number of CABG ICD codes that you can select from, but we will focus on ICD-10 codes related to complications that arise from CABG.

Please note that the following codes have one of three specific terms:

  • Initial encounter: This means the patient receives active CABG-related complication treatment.
  • Subsequent encounter: This means the patient is in the recovery phase but is still being given routine care for their CABG-related complication.
  • Sequela: This means the patient is dealing with the late effects of a particular problem (CABG-related, in this case). Given this, ICD-10 codes with this label should be accompanied by two other ICD-10 codes, one of which should designate the sequela’s nature, while the other should describe the sequela (meaning its effects). 

Here are the CABG-related ICD-10 codes:

  1. T82.211A - Breakdown (mechanical) of coronary artery bypass graft, initial encounter

This ICD-10 code is meant to be used on a patient confirmed to have a coronary artery bypass graft that had a (mechanical) breakdown), and the patient is being actively treated for it. Normally, CABG involves the use of a heart-lung bypass machine, which is used to pump blood into the heart while the heart is temporarily stopped.

  1. T82.211D - Breakdown (mechanical) of coronary artery bypass graft, subsequent encounter

This is the same as Item 1, but this time, the patient is in the recovery phase and is being given routine care.

  1. T82.211S - Breakdown (mechanical) of coronary artery bypass graft, sequela

This is the same as Item 1, but this time, the patient is currently dealing with the effects of the coronary artery bypass graft breakdown.

  1. T82.212A - Displacement of coronary artery bypass graft, initial encounter

This is the same as Item 1, but this time, it’s for the displacement of a coronary artery bypass graft.

  1. T82.212D - Displacement of coronary artery bypass graft, subsequent encounter

This is similar to Item 2, but this time, it’s for a CABG displacement..

  1. T82.212S - Displacement of coronary artery bypass graft, sequela

This is similar to Item 3, but this time, it’s for the late effects of a CABG displacement.

  1. T82.213A - Leakage of coronary artery bypass graft, initial encounter

This is similar to Item 1, but this time, it’s for the leakage of a coronary artery bypass graft.

  1. T82.213D - Leakage of coronary artery bypass graft, subsequent encounter

This is similar to Item 2, but this time, it’s for a CABG leakage.

  1. T82.213S - Leakage of coronary artery bypass graft, sequela

This is similar to Item 3, but this time, it’s for the late effects of a CABG leakage.

  1. T82.218A - Other mechanical complication of coronary artery bypass graft, initial encounter

This is similar to Item 1, but this time, it’s for a kind of CABG mechanical complication that doesn’t have a specific ICD-10 code.

  1. T82.218D - Other mechanical complication of coronary artery bypass graft, subsequent encounter

This is similar to Item 2, but this time, it’s for a kind of CABG mechanical complication that doesn’t have a specific ICD-10 code.

  1. T82.218S - Other mechanical complication of coronary artery bypass graft, sequela

This is similar to Item 3, but this time, it’s for the late effects of a kind of CABG mechanical complication that doesn’t have a specific ICD-10 code.

Are these CABG ICD 10 codes billable?

Yes. All of these CABG-related ICD-10 codes are valid and billable.

Clinical information about CABG:

CABG is short for Coronary Artery Bypass Graft. This type of procedure is done to treat Coronary Artery Disease. Narrow coronary arteries characterize this disease due to fatty material build-up. These materials clog the arteries, lessening the amount of oxygen-rich blood entering the heart or blocking it completely. 

What CABG does is that it creates an alternate pathway by grafting a part of the artery to a healthy blood vessel. Healthcare professionals who perform this surgery will open up the chest and temporarily stop the heart so they can graft the blood vessels. A heart-lung bypass machine will be used to pump blood into the heart while the heart is temporarily stopped.

Synonyms include:

  • Complication of bypass graft
  • Mechanical complication due to coronary bypass graft
  • Mechanical complication of coronary bypass

Commonly asked questions

Are there any unbillable CABG ICD codes?

Yes. These CABG-related ICD-10 codes are not specific. This means that they don’t have the appropriate labels that can make them specific, like initial encounter, subsequent encounter, and sequela.

What are the symptoms of coronary artery disease that may warrant a CABG procedure?

People with coronary artery disease may experience/exhibit the following symptoms: feeling fatigued, having shortness of breath, they feel pain in their chest, they have palpitations, and they have abnormal heartbeats.

What are the risks of CABG Surgery?

CABG has life-threatening risks, just so you know. These include graft failure, bleeding (during and/or after surgery), blood clots, infections, and death.
