ICD-10 Code I83.891 – Varicose veins of right lower extremity with other complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.891 – Varicose veins of right lower extremity with other complications
What it is
This code identifies varicose veins in the right leg when another documented complication is present, but the record does not specify a more exact complication code. Use it for symptomatic or complicated right-sided venous disease.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include visibly enlarged, twisted superficial veins in the right lower extremity with associated pain, swelling, skin changes, or another noted complication.
When to use this code
Use I83.891 when the provider documents varicose veins of the right lower extremity plus an additional complication, and no more specific ICD-10 option is recorded. It may apply when the note clearly links the complication to the right leg veins. Check documentation if the complication is not named.
Do not use for
Do not use this code for uncomplicated varicose veins or for disease in the left leg or both legs. If the documentation identifies a different, specific venous complication, code that condition instead.
Coding tip
Match the laterality and the documented complication exactly; if either is unclear, query the provider.
