ICD-10 Code I25.758 – Atherosclerosis of native coronary artery of transplanted heart with other forms of angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.758 – Atherosclerosis of native coronary artery of transplanted heart with other forms of angina pectoris
What it is
This code identifies atherosclerotic narrowing in the native coronary artery of a transplanted heart, with angina that is not described as unstable or due to spasm. Use it when documentation links both the transplant heart and the specific angina type.
Clinical signs
Patients may have chest discomfort, exertional pain, or ischemic symptoms related to coronary artery disease in the transplanted heart. Clinical features vary; refer to documentation and any supporting cardiac evaluation.
When to use this code
Use this code when the provider documents atherosclerosis affecting a native coronary artery in a transplanted heart and specifies another form of angina pectoris. It fits records that clearly connect the coronary disease to the transplant heart. Check documentation if the angina type is unclear.
Do not use for
Do not use this code for unstable angina, vasospastic angina, or coronary disease not documented as involving a transplanted heart. If the record lacks the required specificity, do not assume this code.
Coding tip
Verify that both “transplanted heart” and the exact angina description appear in the note before assigning I25.758.
