Update Dx to HCC Mappings for 2021, 2022, 2023

[dr00b]

Each year, CMS releases updated dx to HCC mappings as the diagnosis code-set evolves. The the files used in hccpy are copied directly from the public SAS models posted by CMS here. The SAS models are named like so: "2021 Midyear-Final-Model Software.zip".

In hccpy, the mappings from the SAS models are copied to the data dir. The "AllYearsCombined" mapping is a dedup'd combination of all the annual codesets released for a given model version. Below are examples for V24... F2421P1M.TXT F2421P2M.TXT F24_AllYearsCombined.TXT

Tasks:

• [x] Update 2021 V22 and V24 mappings to the finalized mappings.
• [x] Update 2022 V22 and V24 mappings to the finalized mappings.
• [ ] Update 2023 V22 and V24 mappings to use preliminary mappings.
• [x] Make sure the "AllYearsCombined" mappings are updated. The function utils.combine_dx2cc can help with this.
• [x] Update hccpy.HCCEngine.fnmaps to include any new files
