About
HCC Buddy puts ICD-10-CM references on your iPhone. Search by code or diagnosis name, open the code page, and check the edition before you continue your work.
Choose the ICD-10-CM edition separately from the HCC model and year. The starting choices follow your phone's local date. You can keep a specific edition or year selected for the reference you need.
Code pages start with separate cards for CMS-HCC V28, CMS-HCC V24, ESRD, PACE, RxHCC and HHS-HCC. Select one model when you want to focus. Cards label the applicable payment, benefit or calendar year. If a source is unavailable for your selection, the app says so.
Search guideline text and open official source links for more context. The Edition screen shows which reference you are using. Recent code lookups stay on your device and reopen with their saved ICD-10-CM edition.
Search provider records by name or NPI.
An internet connection is needed for reference lookups. HCC Buddy supports coding research and does not replace source guidelines or your coding judgment.
