ICD-10 Code I83.812 – Varicose veins of left lower extremity with pain (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I83.812 – Varicose veins of left lower extremity with pain
What it is
I83.812 identifies varicose veins in the left lower extremity when pain is documented. Use it when the record shows enlarged, twisted superficial veins with left-sided leg pain attributed to the varicosities.
Clinical signs
Typical findings include visible or palpable dilated superficial veins, aching or heaviness in the left leg, and discomfort that worsens with standing. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents varicose veins in the left leg and specifically links them to pain. It is appropriate for outpatient, office, or hospital records when the diagnosis is confirmed in the assessment. If laterality or pain is unclear, check documentation before coding.
Do not use for
Do not use I83.812 for varicose veins without pain, or for venous disorders that are not documented as varicose veins. Do not assume left-sided disease if the record only says “varicose veins.”
Coding tip
Code the laterality and the pain only when both are explicitly documented.
