How This Tool Works
PlainInsurer grades insurance companies on an A through F scale based on:
- Complaint Ratio — NAIC complaint volume normalized by premium volume (Market Conduct Annual Statement data)
- Claim Denial Rate — CMS Transparency in Coverage data showing how often claims are denied
- Prior Authorization Score — CMS Medicare Advantage data on prior auth approval rates
All data is publicly available from government sources. See our methodology page for details on scoring calculations.
