How we choose our network providers and hospitals
Kaiser Permanente uses the same quality, member experience, or cost-related measures to select practitioners and facilities in Marketplace Silver-tier plans as it does for all other Kaiser Foundation Health Plan (KFHP) products and lines of business, and uses the same geographic distribution consideration to select hospitals in Marketplace plans as it does for all other Kaiser Foundation Health Plan (KFHP) products and lines of business. The measures may include, but are not limited to, HEDIS/CAHPS performance, member/patient complaints, patient safety scores, hospital quality measures, and geographic need. Members enrolled in KFHP Marketplace plans have access to all professional, institutional and ancillary health care providers who participate in KFHP plans' contracted provider network, in accordance with the terms of the members' KFHP plan of coverage. All Kaiser Permanente Medical Group physicians and network physicians are subject to the same quality review processes and certifications.
A narrow network is defined as a tailored, tiered, or high-performance network that has 80 percent or less overlap with a health plan’s broadest network offered to a member in any type of plan offered by that health plan. Kaiser Permanente does not have a narrow network with respect to its Marketplace plans. Members enrolled in Kaiser Foundation Health Plan (KFHP) Marketplace plans have access to the same provider networks as members enrolled in all other KFHP plans.
