2025 ICD-10-CM code I25.7

Atherosclerosis of coronary artery bypass graft(s) and coronary artery of a transplanted heart with angina pectoris.

Adhere to the official ICD-10-CM coding guidelines published by CMS.Consult the most current version to ensure accurate and compliant coding practices.Consider additional codes to provide a more detailed clinical picture.

ICD-10 codes do not use modifiers.Modifiers are used with CPT and HCPCS codes.

Medical necessity is established by the presence of angina pectoris related to the diagnosed atherosclerosis in the bypass grafts and/or native coronary arteries.Documentation should support the severity of angina, the impact on the patient's quality of life, and the need for medical management.

The clinical responsibility lies with the cardiologist or cardiac surgeon managing the patient's angina and atherosclerosis.This includes diagnosing the condition, managing the patient's symptoms, and possibly recommending or performing further procedures.

IMPORTANT:Additional codes may be used to specify the type of atherosclerosis (I25.83 for lipid-rich plaque, I25.84 for calcified lesions), the presence of chronic total occlusion (I25.82), and associated factors like tobacco use (Z72.0), tobacco dependence (F17.-), or exposure to environmental tobacco smoke (Z77.22, Z57.31).Excludes codes I25.810, I25.811, and I25.812 (atherosclerosis without angina pectoris in various contexts).

In simple words: This code means that there's a hardening of the arteries in both the new blood vessels used to bypass blocked arteries (coronary artery bypass grafts) and in the arteries of a transplanted heart.This is causing chest pain (angina).

This code signifies atherosclerosis affecting both coronary artery bypass grafts and the coronary artery of a heart transplant, accompanied by angina pectoris (chest pain).The presence of angina pectoris is a critical component of this diagnosis.Additional codes may be necessary to specify the type of coronary atherosclerosis (e.g., due to calcified lesions or lipid-rich plaques) and to indicate other relevant conditions such as tobacco use or chronic total occlusion.

Example 1: A patient who underwent a coronary artery bypass graft (CABG) surgery years ago presents with recurrent chest pain (angina).Angiography reveals atherosclerosis in both the bypass grafts and the native coronary arteries of the heart.I25.7 is used to code this., A patient with a heart transplant experiences chest pain (angina).Cardiac catheterization confirms the presence of atherosclerosis in the transplanted heart's coronary arteries. I25.7 is coded, highlighting the unique challenge of atherosclerosis in a transplanted organ., A patient with a history of CABG and a heart transplant has stable angina for many years but recently experienced worsening symptoms. The physician diagnoses this as progressive atherosclerosis affecting both the bypass grafts and the native coronary arteries. I25.7, along with additional codes indicating the severity of the angina, is used in this case.

Detailed medical history, including past cardiac procedures (CABG, heart transplant), current symptoms (angina), and results of diagnostic tests (angiography, cardiac catheterization) are essential for accurate coding.Documentation should clearly establish the presence of angina and the location of atherosclerosis (bypass grafts and/or native coronary arteries).

** This code should only be used when angina pectoris is present.If atherosclerosis is present without angina, a different code should be used.Always refer to the latest official ICD-10-CM guidelines for clarification and updates.
