What This Code Means

I82.601 is the ICD-10-CM diagnosis code for acute embolism and thrombosis of unspecified veins of right upper extremity. A sudden blood clot in the veins of the right arm or hand. I82.601 sits in the ICD-10-CM chapter for diseases of the circulatory system (i00-i99), within the section covering diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified (i80-i89).

I82.601 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
