About I86.3
I86.3 is the ICD-10-CM diagnosis code for Vulval 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), I86.3 is specifically for Vulval varices. Related codes cover sublingual varices (I86.0), scrotal varices (I86.1), pelvic varices (I86.2), gastric varices (I86.4) and varicose veins of other specified sites (I86.8).
Don't report I86.3 together with the conditions in its Excludes1 note: vulval varices complicating childbirth and the puerperium (O87.8) and vulval varices complicating pregnancy (O22.1-).
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 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 760 (Menstrual and Other Female Reproductive System Disorders with CC/MCC, relative weight 1.0129) and DRG 761 (Menstrual and Other Female Reproductive System Disorders without CC/MCC, relative weight 0.7041), in MDC 13 (Diseases and Disorders of the Female 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 female 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 456.6 (Vulval varices).
