OAKLAND, Calif. Oct. 7, 2022 – Kaiser Permanente’s Medicare health plan in California is once again among the nation’s best for providing high-quality, seamless care and outstanding service to its Medicare health plan members.

The Kaiser Permanente Medicare health plan in California received 5 out of 5 stars, the highest rating possible, according to the Centers for Medicare & Medicaid Services (CMS) annual Star Quality Ratings for 2023.

This is the 12th straight year Kaiser Permanente’s Medicare health plan in California has been rated 5 out of 5 stars.

“Kaiser Permanente is proud to be consistently rated among the best in the nation for providing high-quality care and service to our Medicare health plan members — and all of our members — throughout Northern California,” said Carrie Owen Plietz, FACHE, president of Kaiser Permanente’s Northern California region. “This 5-star rating reflects the unwavering commitment of our physicians, care teams and staff to keeping our members leading healthy and productive lives.”

The CMS Medicare Part C (health plan) and Part D (drug plan) 5-Star Quality Rating system is designed to help people compare health and drug plans based on quality and performance. Plans that receive 5 out of 5 stars in the annual ratings are recognized as excellent. Plans that receive 4 out of 5 stars are above average.

The Medicare health plans in every other Kaiser Permanente region in the U.S. have been rated 4.0 stars or higher from the Centers for Medicare & Medicaid Services for 2023. Kaiser Permanente provides care to 1.8 million Medicare members (out of 12.6 million members total) in 8 states and the District of Columbia.

“These ratings demonstrate the commitment of our physicians and care teams to providing excellent care and service to our patients,” said Richard S. Isaacs, MD, FACS, chief executive officer and executive director of The Permanente Medical Group. “Our clinical expertise combined with the high-quality care we provide is improving the health and well-being of our members and patients.”

Every year, CMS rates all Medicare Advantage health plans (Parts C and D) on multiple facets of care and service, including chronic conditions management, health maintenance, patient experience, customer service and pharmacy services. Kaiser Permanente’s star ratings demonstrate the value of our integrated health care delivery system, which brings a myriad of services together, in many cases all under one roof, and puts our patients at the center of care.

Enrolling in a Kaiser Permanente Medicare health plan

Medicare-eligible people can enroll in individual Medicare Advantage plans during the Medicare open enrollment period, which begins October 15 and runs through December 7, 2022. People who have a 5-star-rated Medicare health plan available in their area may take advantage of a special enrollment period to join or switch to that plan at virtually any other time of the year (one plan change allowed per special enrollment period).
