ICD-10 Code I87.8 – Other specified disorders of veins (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.8 – Other specified disorders of veins
What it is
I87.8 identifies vein disorders that are documented but do not fit a more specific ICD-10 category. Use it when the provider describes an unusual or specified venous condition without a better code.
Clinical signs
Clinical features vary; refer to documentation. Findings may include venous pain, swelling, visible vein changes, or other signs of chronic venous disease when the record does not support a more specific diagnosis.
When to use this code
Use I87.8 when the clinician documents a named venous disorder that is not indexed elsewhere in ICD-10-CM. It may apply to localized or atypical venous abnormalities, provided the note supports a vein-related diagnosis. Check documentation if the record only describes symptoms without a confirmed disorder.
Do not use for
Do not use this code for varicose veins, venous embolism, thrombosis, or chronic venous insufficiency when a more specific code is available. Do not assign it for nonspecific leg swelling alone.
Coding tip
Match the exact provider wording to the index and code the most specific venous diagnosis supported by the chart.
