ICD-10 Code I83.899 – Varicose veins of unspecified lower extremity with other complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.899 – Varicose veins of unspecified lower extremity with other complications
What it is
This code identifies varicose veins in an unspecified lower extremity when the chart documents another complication, but not a more specific one. Use it when the affected leg is not named and the complication is not separately coded.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include visibly enlarged, twisted superficial veins with symptoms such as aching, heaviness, swelling, or skin changes when a complication is present.
When to use this code
Use I83.899 when the provider documents varicose veins in a lower limb and specifies an additional complication, but does not identify the side. This code fits records that support varicose veins with complication, yet lack enough detail for a more specific lower-extremity code.
If the note names the right or left leg, choose the laterality-specific code instead. If the complication is unclear, check documentation before coding.
Do not use for
Do not use this code for uncomplicated varicose veins or for varicose veins in a specified leg when laterality is documented. Do not use it when the condition is better described by another venous disorder; check documentation.
Coding tip
Confirm both the lower-extremity location and the documented complication before assigning I83.899.
