About coding stomach varix
The ICD-10-CM code for stomach varix is I86.4 (Gastric varices).
Within I86 (varicose veins of other sites), I86.4 is specifically for gastric varices. Related codes cover sublingual varices (I86.0), scrotal varices (I86.1), pelvic varices (I86.2), Vulval varices (I86.3) and varicose veins of other specified sites (I86.8).
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 299 (Peripheral Vascular Disorders with MCC, relative weight 1.5842), DRG 300 (Peripheral Vascular Disorders with CC, relative weight 1.0464) and DRG 301 (Peripheral Vascular Disorders without CC/MCC, relative weight 0.7133), in MDC 05 (Diseases and Disorders of the Circulatory 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.
