What This Code Means
D13.4 is the ICD-10-CM diagnosis code for benign neoplasm of liver. A noncancerous tumor growing in the liver. D13.4 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D13.4 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Confirm benign histology; hepatic cancers require malignant neoplasm codes.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D13.4 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Confirm benign histology; hepatic cancers require malignant neoplasm codes
- •Document if the tumor is causing hepatic dysfunction or mass effect on adjacent structures
