About coding venous angioma
The ICD-10-CM code for venous angioma is Q28.3 (Other malformations of cerebral vessels).
Within Q28, choose Q28.3 (Other malformations of cerebral vessels) only when documentation doesn't support a more specific option: arteriovenous malformation of precerebral vessels (Q28.0), other malformations of precerebral vessels (Q28.1), arteriovenous malformation of cerebral vessels (Q28.2), other specified congenital malformations of circulatory system (Q28.8) and congenital malformation of circulatory system, unspecified (Q28.9).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
