Kaiser Permanente’s Medicare HMO health plan in California has received a 4.5 out of 5 stars rating from the Centers for Medicare & Medicaid Services (CMS) for 2026, tying for the highest score in the state. The plan serves more than 1.4 million Medicare Advantage members.
“Kaiser Permanente continues to lead the nation in quality measures, which reflects our ongoing commitment to improving health outcomes for our Medicare Advantage members, some of whom have complex health conditions,” said Mike Bowers, FACHE, interim president of Kaiser Permanente’s Northern California region. “Through a combination of high-quality care, affordability, and coordination across specialties we are providing our patients with needed support to lead healthy lives.”
The organization’s Medicare HMO plan has consistently earned either 4.5 or 5 stars since 2011.
“Our dedicated clinical teams provide our Medicare Advantage patients with seamless, personalized care that enables them to live full and active lives,” said Maria Ansari, CEO and executive director of The Permanente Medical Group. “Kaiser Permanente’s Medicare Advantage California Plan is also highly rated on many measures, including colorectal cancer and breast cancer screening.”
Each year, CMS evaluates Medicare Advantage and prescription drug plans based on several categories such as patient experience, access to care, customer service, and management of chronic conditions.
Additionally, Kaiser Permanente recently received recognition from the National Committee for Quality Assurance (NCQA), which awarded its Northern California Medicare and commercial plans five stars for overall patient experience and clinical quality—the highest possible rating. Kaiser Permanente Northern California has achieved this distinction ten times and is among only 11 health plans nationwide to earn a perfect score.
