About I86.1

I86.1 is the ICD-10-CM diagnosis code for scrotal varices. It belongs to category I86 (varicose veins of other sites), block I80-I89 (diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified) and chapter 9 (diseases of the circulatory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

It is on the CMS list of diagnoses consistent only with male patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 456.4 (scrotal varices).
