About coding intracranial angioma
The ICD-10-CM code for intracranial angioma is D18.02 (Hemangioma of intracranial structures).
Within D18.0 (Hemangioma), D18.02 is specifically for Hemangioma of intracranial structures. Related codes cover unspecified site (D18.00), of skin and subcutaneous tissue (D18.01), of intra-abdominal structures (D18.03) 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 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), in MDC 01 (Diseases and Disorders of the Nervous 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.
