EVERETT — Group Health is notifying about 100 people in Snohomish County that some of their medical information was accidentally disclosed as part of mailing sent out last month.
The problem occurred when a letter from the cooperative was sent to heart disease and diabetes patients to notify them about additional treatment options.
Member numbers and medical conditions were mistakenly included in the address field of the envelope as part of a mailing sent to about 1,000 patients.
Group Health officials said no other personal information was disclosed. They called it an isolated incident. The medical cooperative has offered affected patients one year of free identity theft and credit monitoring protection.
