Must health insurance companies submit rate filings each year?
In most cases, health insurance companies only need to submit a rate filing if they are requesting a change in rates. However, companies must submit rate filings for Medicare supplement plans even if they are not requesting a change in rates. In addition, health insurance companies must submit a certification each year for small group products, confirming that the rates charged during the past year complied with the law.
