ICD10Data alternative
ICD10Data alternative for HCC coders
ICD10Data.com is one of the most popular free ICD-10-CM lookup tools on the web, but it has no HCC mapping at all. HCC Buddy is an ICD10Data alternative built for HCC and risk adjustment coders: it keeps the free code lookup, then adds current CY2026 V28 mapping, a historical PY2025 V24 reference, and V28 PY2026, complete context required. Public pages retain source-labeled coefficient references. Here is how they compare for coders who need the next layer.

Why coders look for an ICD10Data alternative
ICD10Data.com is a free reference tool designed for quick code lookups. It shows code descriptions, Includes/Excludes notes, and tabular hierarchy navigation. For Medicare Advantage work the next question matters more: does the code map, and what is the RAF value? ICD10Data has no HCC mapping at all, so a risk adjustment coder still needs a second tool. HCC Buddy was built for that coder: a current CY2026 V28 result and historical PY2025 V24 reference appear with each lookup, while source-labeled coefficient references remain available on public reference pages. See the CMS 2026 Model Software ICD-10 mappings.
HCC mapping changes the lookup
ICD10Data shows a code's description and clinical notes. HCC Buddy adds the available HCC category and model version. Public pages retain source-labeled coefficient references. The RAF tool shows a CMS-HCC V28 PY2026 member result only with the complete diagnosis set and member details and passing CMS source checks. Otherwise, it shows no score. For risk adjustment coders, that context is the difference between a basic lookup tool and a purpose-built coding platform. Both tools ultimately source their code descriptions from the same CMS ICD-10-CM code set.
Ad-free, with tools ICD10Data does not offer
ICD10Data is free but ad-supported, with display ads throughout the interface. HCC Buddy has no advertisements and adds Ask Buddy for coding questions, NPI provider lookup across 9.37M records, a drug reference, and a Chrome extension with a side panel and floating sidebar so coders can check ICD-10, HCC mapping, and NPI data without leaving their EHR tab. The extension keeps a Zero PHI posture: it never stores, logs, or transmits patient data.
Where ICD10Data is still the better fit
ICD10Data.com is completely free with no limits and no account required. It has been the go-to ICD-10-CM reference for years, is indexed by search engines for every code, and is excellent for quick one-off lookups by coders who do not need HCC mapping or risk adjustment tools. If you only need to look up a code description occasionally, ICD10Data is hard to beat. HCC Buddy is for the moment when the lookup needs to become a risk adjustment check.

Risk-adjusting code hub
Free lookup is fine. Mapped code depth is the real differentiator.
This directory exposes the billable V28 code pages that a basic free lookup tool does not organize around risk adjustment. It gives readers a direct bridge from comparison content into code-level HCC work.

See the mapping HCC Buddy does in one card
One ICD-10-CM lookup returns available risk-model mapping evidence in a single card. Current CMS-HCC V28 stays distinct from historical PY2025 V24, and code-level coefficients are source-labeled references, not member totals.
