What This Code Means
I83 is the ICD-10-CM diagnosis code for varicose veins of lower extremities. I83 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).
Header codes like I83 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for I83 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
