WASHINGTON — Maryland residents purchasing individual health insurance coverage under the Affordable Care Act can expect to pay higher premiums next year.

The Maryland Insurance Administration has approved rate increases that are expected to affect roughly 96,000 people who buy Silver plans through the state’s health insurance exchange.

The administration approved a 27 percent increase for CareFirst BlueCross Blue Shield for its HMO plan and a 24 percent increase for its PPO plan.

That’s on top of a more than 31 percent increase approved for HMO plans and a 52 percent hike for PPO plans approved in August.

A nearly 21 percent increase has been approved for Kaiser Permanente.
