About coding varicocele
The ICD-10-CM code for varicocele is I86.1 (Scrotal varices). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I86.1.
Within I86 (varicose veins of other sites), I86.1 is specifically for scrotal varices. Related codes cover sublingual varices (I86.0), pelvic varices (I86.2), Vulval varices (I86.3), gastric varices (I86.4) 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 729 (Other Male Reproductive System Diagnoses with CC/MCC, relative weight 1.0544) and DRG 730 (Other Male Reproductive System Diagnoses without CC/MCC, relative weight 0.6597), in MDC 12 (Diseases and Disorders of the Male Reproductive 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.
