About D18.03
D18.03 is the ICD-10-CM diagnosis code for Hemangioma of intra-abdominal structures. It belongs to category D18 (Hemangioma and lymphangioma, any site), block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within D18.0 (Hemangioma), D18.03 is specifically for Hemangioma of intra-abdominal structures. Related codes cover unspecified site (D18.00), of skin and subcutaneous tissue (D18.01), of intracranial structures (D18.02) and of other sites (D18.09).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 391 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCC, relative weight 1.2392) and DRG 392 (Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCC, relative weight 0.7645), in MDC 06 (Diseases and Disorders of the Digestive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 228.04 (Hemangioma of intra-abdominal structures).
