ICD-10 Code C80.2 – Malignant neoplasm associated with transplanted organ (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C80.2 – Malignant neoplasm associated with transplanted organ
What it is
C80.2 identifies a malignant neoplasm that develops in, or is associated with, a transplanted organ. Use it when the record clearly links the cancer to the transplanted organ rather than to a native site.
Clinical signs
Clinical features vary; refer to documentation. You may see imaging, pathology, or transplant follow-up notes describing a new malignant lesion in the grafted organ, with confirmation that the tumor is associated with the transplant.
When to use this code
Use this code when the provider documents malignancy involving a transplanted organ and does not assign a more specific site-based code. It is appropriate when the chart states the cancer is in the transplanted organ or graft. Check documentation if the record only mentions transplant history without a current malignancy.
Do not use for
Do not use it for a past transplant without current cancer, or for malignancy in the native organ when the transplant is unrelated. If the documentation is unclear about the site or relationship, check documentation.
Coding tip
Confirm both the malignancy and the transplant relationship in the provider note before assigning C80.2.
