About coding orbit varix
The ICD-10-CM code for orbit varix is I86.8 (Varicose veins of other specified sites). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on I86.8.
Within I86, choose I86.8 (Varicose veins of other specified sites) only when documentation doesn't support a more specific option: sublingual varices (I86.0), scrotal varices (I86.1), pelvic varices (I86.2), Vulval varices (I86.3) and gastric varices (I86.4).
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.
