Maine’s Bureau of Insurance will hold public comment sessions next month on proposed 10 percent premium increases for Anthem Blue Cross and Blue Shield’s individual policy holders.

Anthem submitted a filing last week proposing an average 9.7 percent increase in premiums for the more than 11,000 policyholders. The increase affects Mainers who buy their own individual coverage instead of getting health insurance through work or a government-sponsored program such as Medicare.

The increases would take effect in July and vary somewhat for the different Anthem plans, including  HealthChoice, HealthChoice Standard & Basic, Lumenos, HMO and HealthChoice HDHP.

The first session will be held from 5 to 7 p.m. March 14 at the University of Maine in Orono.

The second session will be held from 5 to 7 p.m. at the Wishcamper Center at the University of Southern Maine in Portland.

A formal public hearing will be held in early April before the state’s insurance superintendent rules on the rate increase.
