DOVER — Delawareans will have access to increased options on the health insurance marketplace for the second straight year, Insurance Commissioner Trinidad Navarro announced Thursday.

A total of 57 health plans and 12 dental plans will be offered by four insurers, including new carrier Celtic Insurance Company Ambetter Health of Delaware, Aetna Health, AmeriHealth Caritas and Highmark Blue Cross Blue Shield.

Nearly 35,000 residents purchased plans on the marketplace during last year’s open enrollment. After Advance Premium Tax Credits, premiums averaged $197. Almost 6,000 residents were eligible for a premium of $10 a month or less.

Enrollment numbers are expected to rise as Medicaid redeterminations continue following the end of the COVID-19 public health emergency. A special enrollment period for marketplace plans is available for those no longer eligible for Medicaid.

Open enrollment will take place from Nov. 1 through Jan. 15.

In addition, rates for regulated 2024 health, dental and small group insurance plans were also announced Thursday.

Celtic Insurance Company’s 24 new plans range in base cost, before premium tax credits or other subsidies, from $378 to $532. Aetna Health will increase rates by an average of 2%, with base rate for six plans ranging from $414 to $441.

AmeriHealth Caritas will decrease rates an average of 4.52%. Base rates for their six Marketplace plans will cost $300 to $416. Highmark requested a rate increase, and an average increase of 3.2% was approved after an initial increase request of 4.9%. Their 18 Marketplace plans have base costs between $274 and $654.
