T82.211A is a billable diagnosis code used to specify a medical diagnosis of breakdown (mechanical) of coronary artery bypass graft, initial encounter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

T82.211A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like breakdown (mechanical) of coronary artery bypass graft. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit". The 7th character should be used when the patient is undergoing active treatment regardless if new or different providers saw the patient over the course of a treatment. The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Patient Education


Coronary Artery Bypass Surgery

In coronary artery disease (CAD), the arteries that supply blood and oxygen to your heart muscle grow hardened and narrowed. You may try treatments such as lifestyle changes, medicines, and angioplasty, a procedure to open the arteries. If these treatments don't help, you may need coronary artery bypass surgery.

The surgery creates a new path for blood to flow to the heart. The surgeon takes a healthy piece of vein from the leg or artery from the chest or wrist. Then the surgeon attaches it to the coronary artery, just above and below the narrowed area or blockage. This allows blood to bypass (get around) the blockage. Sometimes people need more than one bypass.

The results of the surgery usually are excellent. Many people remain symptom-free for many years. You may need surgery again if blockages form in the grafted arteries or veins or in arteries that weren't blocked before. Lifestyle changes and medicines may help prevent arteries from becoming clogged again.
