Where are the ICD-10 to HCC mappings located?
The ICD-9 and ICD-10 mappings of diagnoses to model the Hierarchical Condition Category (HCC) and the model software are available on the CMS Risk Adjustment website https://www.cms.gov/Medicare/Health-Plans/MedicareAdvtgSpecRateStats/Risk-Adjustors.html. CMS has also posted the PY2020 initial mappings and model software on that website.
