About I83.201

I83.201 is the ICD-10-CM diagnosis code for varicose veins of unspecified lower extremity with both ulcer of thigh and inflammation. It belongs to category I83 (varicose veins of lower extremities), 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 I83.20 (varicose veins of unspecified lower extremity with both ulcer and inflammation), I83.201 is specifically for varicose veins of unspecified lower extremity with both ulcer of thigh and inflammation. Related codes cover of calf and inflammation (I83.202), of ankle and inflammation (I83.203), of heel and midfoot and inflammation (I83.204), other part of foot and inflammation (I83.205), of other part of lower extremity and inflammation (I83.208) and of unspecified site and inflammation (I83.209).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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.

The Medicare Code Editor expects this diagnosis only for patients age 15 through 124.

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 454.2 (varicose veins of lower extremities with ulcer and inflammation).
