V24 HCC 84 (Archived Category) ICD-10-CM
HCC 84 is a payment category of the retired CMS-HCC V24 model, which last determined Medicare Advantage payment in 2025. The 27 ICD-10-CM codes below are its final mappings, kept for lookback analysis and RADV audit reference. Each code shows where it maps in the live V28 model; 6 of them no longer risk-adjust at all.

Questions About This Archived Category
Is V24 HCC 84 still paid?
No. The CMS-HCC V24 model last determined Medicare Advantage payment in 2025; from payment year 2026 the V28 model pays 100% of the risk score. This page exists for lookback analysis and RADV audit periods that predate the transition.
Where did these codes go in V28?
Each row above names the code's live V28 category, or marks it as having no V28 successor. The category-level picture, with destination counts for every V24 category, is on V24 to V28: What Changed.
