## What is HCC Buddy?

HCC Buddy is an ICD-10-CM lookup and HCC coding reference for iPhone. Code search is free and works without an account.

LOOK UP A CODE
Search by code or diagnosis name. Check the description and billable status, then review Tabular instructions and official source links. Search Guidelines text or find provider records by name or NPI.

CHOOSE THE DATE AND EDITION
Start with today's date on your device, or choose a date of service. Review supported FY2025, FY2026 and FY2027 releases. FY2027 starts October 1, 2026. Choose the release that applies to your date of service and check for any April update.

KEEP HCC CONTEXT IN VIEW
Choose the HCC model and its year separately from the ICD-10-CM edition. CMS-HCC uses a payment year; HHS-HCC uses a benefit year. HCC categories are shown where verified mapping data is available for your selection. FY2027 HCC mappings remain pending.

SAVE CODES YOU RETURN TO
Sign in to save bookmarks and a code basket. Your HCC Buddy account also works on hccbuddy.com.

ASK BUDDY WHEN YOU NEED A SOURCE
Ask Buddy is optional and requires an account and acceptance of its model-processing notice. Reference mode covers code descriptions, billable status and Tabular instructions. HCC mappings and RAF scores are outside that mode. Available answers depend on the selected sources.

Check the source links shown with answers. Ask access and allowances depend on your account and plan; current access is shown in the app.

Internet access is required. HCC Buddy is a reference aid for coding work. Check official sources and use your coding judgment. HCC Buddy is not affiliated with or endorsed by CDC, CMS, HHS or the U.S. government.
