ICD-10 Code I82.721 – Chronic embolism and thrombosis of deep veins of right upper extremity (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I82.721 – Chronic embolism and thrombosis of deep veins of right upper extremity
What it is
This code identifies a long-standing clot or embolus in the deep veins of the right upper arm or shoulder region. Use it when the condition is chronic, not acute, and documentation specifies the right upper extremity.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include arm swelling, pain, heaviness, or visible collateral veins, but the record should support chronic deep venous obstruction.
When to use this code
Use I82.721 when the provider documents chronic embolism or thrombosis involving deep veins of the right upper extremity. It may also apply when follow-up notes describe a persistent, established clot rather than a new event. Check documentation for laterality and chronicity.
Do not use for
Do not use this code for acute upper-extremity DVT, superficial vein thrombosis, or unspecified limb laterality. If the note does not clearly state chronic disease or right-sided involvement, check documentation.
Coding tip
Verify both chronicity and right upper-extremity location before assigning I82.721.
