ICD-10 Code I25.751 – Atherosclerosis of native coronary artery of transplanted heart with angina pectoris with documented spasm (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.751 – Atherosclerosis of native coronary artery of transplanted heart with angina pectoris with documented spasm
What it is
This code identifies atherosclerotic narrowing in a native coronary artery of a transplanted heart, with angina pectoris and documented coronary spasm. Use it when the record clearly links the symptoms to this specific transplant-heart coronary disease.
Clinical signs
Typical documentation may include angina symptoms, evidence of coronary artery disease in the transplanted heart, and confirmed spasm on testing or clinical assessment. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a transplanted heart with native coronary artery atherosclerosis plus angina pectoris and documented spasm. It is appropriate when the note explicitly states the transplant-related coronary disease and the spasm diagnosis. Check documentation if the record only mentions chest pain or unspecified coronary disease.
Do not use for
Do not use this code for angina without documented spasm, or for coronary disease not involving a transplanted heart. If the chart does not specify atherosclerosis of the native coronary artery, use a more accurate documented diagnosis.
Coding tip
Confirm that all elements are documented together: transplanted heart, native coronary artery atherosclerosis, angina pectoris, and documented spasm.
