Before we start, who are you?
Same data either way. The difference is what the tool puts in front of you, and how it talks about what it finds.

What does the documentation actually support?

Search any ICD-10-CM code against the CMS-HCC V28 model, build a patient scenario, and see exactly how hierarchy, interactions, and the payment HCC count change the result.

CMS-HCC V28 PY2027 FACTORS CODER VIEW

Find a diagnosis

Type an ICD-10 code or part of a description. 8,299 codes map to a V28 payment HCC; everything else returns no risk weight.

Patient

Segment and demographics set the base factor before any diagnosis is counted.

Scenario

Codes you have added. Hierarchy suppression and interactions are shown, never applied silently.

    Where did my old HCC go?

    V24 was retired on 1 January 2026. Enter a V24-era HCC number to see where its codes landed in V28.

    Educational tool. Code only what the record supports. Risk adjustment coding must reflect conditions documented, assessed, and managed at a face-to-face encounter in the data collection year. This tool does not determine medical necessity and is not coding, billing, legal, or clinical advice. Payment figures are illustrative: real capitation depends on county benchmark, bid, star rating, and plan-specific factors. Hierarchy is applied only for verified severity families and is shown, not hidden. Verify against the official CMS model software before relying on any result.
