Cigna and Kaiser Permanente are both major players in the Medicare insurance game. So how do these competitors stack up against one another, and which one might be the best fit for your needs? 

In this review, we’ll break down these two companies to help you decide which company offers the best Medicare plan for your needs.

Kaiser Permanente: Patient-Focused HMO Medicare Plans

The key difference between Cigna and Kaiser Permanente is that Kaiser Medicare plans tend to be more HMO-focused. While the company offers other types of Medicare Advantage (Medicare Part C) coverage, such as PPO (Preferred Provider Organization) plans, HMO (Health Maintenance Organization) plans are its bread and butter. 

An HMO Medicare Advantage plan tends to be more patient-focused and emphasizes preventive care with a team-oriented approach.

  • In an HMO plan, you’ll utilize a primary care physician (PCP) who you see for all initial appointments.
  • If the primary care physician decides additional tests are needed or that you need specialized care, they will coordinate with a team of specialists and other health care providers within the plan’s network to set you up with an appointment. 

HMO plans are a type of managed care designed to reward participating providers who achieve good health outcomes among their members. 

Kaiser Permanente owns its own health care facilities and employs their own doctors in some areas. It’s like a medical facility and health insurance plan all in one. 

Cigna, on the other hand, offers HMO plans, PPO plans and other types of Medicare Advantage plans and does not own its own health care facilities or employ its own doctors.
