What This Code Means
D18.03 is the ICD-10-CM diagnosis code for hemangioma of intra-abdominal structures. A benign blood vessel tumor found in organs or structures within the abdominal cavity, such as the liver, spleen, or intestines. D18.03 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D18.03 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Specify the organ involved in documentation when possible for clinical clarity.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for D18.03 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
