ICD-10 Code I87.1 – Compression of vein (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I87.1 – Compression of vein
What it is
This code identifies a condition where a vein is compressed by nearby structures, limiting normal blood flow. It is used when the provider documents vein compression as the diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include venous congestion, swelling, discomfort, or visible venous obstruction on imaging.
When to use this code
Use I87.1 when the record clearly states compression of a vein, such as from an anatomic structure or external mass. You may also use it when imaging or specialist documentation confirms venous compression as the cause of symptoms. Check the note for the specific vein involved if reported.
Do not use for
Do not use this code for arterial compression or for general venous insufficiency without documented vein compression. If the record only says edema, pain, or thrombosis, check documentation.
Coding tip
Code the documented cause of compression, when available, and verify laterality or site details in the chart.
