CIGNA has introduced a new series of dental HMO plans the insurer says places an even greater emphasis on affordability and promoting wellness by covering more preventative dental care services.

Under the new plans, for example, up to four routine cleanings a year (two at no cost and two for a minimal copay), are covered when recommended by a dentist and children are covered for two fluoride treatments a year to help prevent tooth decay.

Dr. Miles Hall, chief dental clinical director for CIGNA, said the Bloomfield, Conn.-based insurer is also changing some aspects of plan rules to make it easier for clients to schedule preventative dental care. To do so, the insurer is doing away with a requirement that cleanings be done at least six months apart.

The new plans also cover teeth whitening and continue to include preventative features such as no age limitation on sealants, no referrals needed for orthodontic care or care by a network pediatric dentist for children under 7, and coverage for procedures to help detect oral cancer early.
