MO SB1596

Requires dental plans to maintain a minimum 85% dental loss ratio, meaning at least 85% of premiums must be spent on actual patient care rather than administrative costs or overhead

Mandates dental plans file annual dental loss ratio reports with the Missouri Department of Commerce and Insurance by March 1st of each year, using the same format as the 2013 federal dental loss ratio reporting form (CMS-10418)

Requires dental plans to issue pro rata rebates to enrollees by August 1st if the dental loss ratio falls below 85%, with the rebate amount equal to the excess spent on overhead/administrative costs

Excludes state-sponsored programs from these requirements, including MO HealthNet and the state children's health insurance program (CHIP)

Classifies failure to provide required rebates by unlicensed dental plans as an unlawful practice under Missouri's consumer protection statutes (section 407.020)
