ClassCheck doesn't support Michigan yet

Michigan is an independent-bureau state (CAM) with its own class codes and rating rules, not NCCI's.

In plain English: Michiganruns its own rating bureau instead of using NCCI, so class codes, code definitions, and rates are set by that bureau — not NCCI. Our class-code lookups and misclassification rules are built on NCCI's Scopes Manual, which doesn't line up cleanly with Michigan's system, so running our checker against a Michigan audit would give you unreliable results.

This may expand as we build out state-specific rule sets, so it's worth checking back or leaving your email below. In the meantime, you can still browse other states and the full class-code index.
