Code Book source manifest
Descriptors come from the CDC/NCHS FY2026 tabular XML, and billable status comes from the CMS order file. CY2026 non-PACE CMS-HCC results use V28. Generic V24 is labeled as a historical PY2025 reference. ESRD and RxHCC use their own model versions, and PACE requires a separate blended calculation. Missing evidence stays pending instead of becoming a guessed value. For FY2025 code lookups, HCC Buddy keeps the October and April ICD-10-CM packages separate. The PY2025 V24 payment reference does not identify the code-set period.

If you need the current code book itself, download it from the agencies that publish it. HCC Buddy does not host the CMS zip and does not sell affiliate copies.
