I83.811Varicose veins of right lower extremity with pain

I83.811 is the ICD-10-CM diagnosis code for varicose veins of right lower extremity with pain. 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 I83.81 (varicose veins of lower extremities with pain), I83.811 is specifically for varicose veins of right lower extremity with pain. Related codes cover left lower extremity with pain (I83.812), bilateral lower extremities with pain (I83.813) and unspecified lower extremity with pain (I83.819).

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.

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 changed in FY2018 (title revised).

Before ICD-10, this condition was coded in ICD-9-CM as 454.8 (varicose veins of lower extremities with other complications).
