BCBS takes the gold with an extensive health insurance provider network of 1.7 million. Kaiser’s network includes 39 hospitals, 737 medical offices, 23,656 physicians and 65,005 nurses. While Kaiser’s network is still large, it pales next to BCBS’ massive network.

Blue Cross Blue Shield Vs Kaiser Permanente: Cost

BCBS and Kaiser healthcare plans will vary in cost due to:

  • Age
  • Deductible
  • Health history
  • Health plan
  • State

Plan categories from both BCBS and Kaiser are available in bronze, silver, gold and platinum. The tiers dictate the cost of your coverage (not the quality of your care):

  • Bronze tier: Lower monthly premium but higher out-of-pocket costs
  • Silver tier: Average monthly payments. Lower out-of-pocket costs compared to bronze but higher than gold
  • Gold tier: Higher monthly payments but lower out-of-pocket costs
  • Platinum tier: Highest monthly payments with the lowest out-of-pocket costs.

BCBS and Kaiser also sell Medicare Advantage (Part C) plans, which combine Medicare Part A (hospital insurance), Part B (medical insurance), and sometimes Part D (prescription drugs). You will still be paying your premiums for Medicare parts A and B on top of your MA plan premium — however, Part A is typically free if you’ve paid Medicare taxes for at least 10 years. The average cost of an MA plan is $19 per month in 2022.

Blue Cross Blue Shield Vs Kaiser Permanente: Coverage Limits

Healthcare policy limits will vary between plans since different people have different needs, budgets and health concerns. Like any other health insurance company, BCBS and Kaiser are prohibited from setting a dollar limit on essential health benefits, which can include:

  • Ambulatory patient services
  • Emergency services
  • Hospitalization (surgery and overnight stays)
  • Laboratory services
  • Mental health and substance use disorder services

Blue Cross Blue Shield Vs Kaiser Permanente: Medical Loss Ratio

Medical loss ratio (MLR) is the revenue from member premiums received versus how much of it is used for medical care improvement. Insurance companies must spend at least 80% (individual plans) or 85% (group plans) of premium dollars on improvements. If the MLR falls below the requirement, the difference is refunded in the form of a rebate for policyholders.

In 2022, BCBS will issue MLR in several states, including Massachusetts, Texas, Minnesota and North Carolina. It is unknown whether Kaiser will be issuing rebates this year. The Kaiser Family Foundation does note that all insurance companies will be paying a total of $1 billion in rebates.

Open enrollment for buying a BCBS or Kaiser health plan through your state’s health insurance marketplace will run from November 1, 2022, to January 15, 2023 in most states. Health insurance coverage is still purchasable outside of the enrollment period but only if you experience a qualifying event, such as:

  • Giving birth to a child or adopting a child
  • Household income falling below the federal poverty level
  • Losing health coverage (spouse or domestic partner loses their job or dies)

Medicaid enrollment lasts year-round for qualified applicants and you can apply by contacting your state’s Medicaid department or enrolling through your state’s health insurance marketplace. Eligibility will vary by state but typically considers the following:

  • Age
  • Income level

How To File Claims With Blue Cross Blue Shield and Kaiser Permanente

In-network care does not require a claim to be filed by the insured for either company. Instead, doctors and medical facilities file claims with the insurance company on your behalf. However, medical services acquired out-of-network will require you to file a claim yourself.

BCBS members can submit claims electronically or by mail. Customers can use the Real-Time Claims web tool for electronic claims submissions or by signing up for the Electronic Data Interchange (EDI).

Kaiser Permanente members can submit claims by mail or by enrolling in the Electronic Data Interchange (EDI).

History of Blue Cross Blue Shield

Blue Cross was formed in 1929 as a partnership between Baylor University Hospital and its patients who were struggling financially. The administrators of the hospital wanted to make healthcare more affordable for some patients, many of whom were Dallas public school educators on restricted budgets. The initial payment plan set up by Baylor University Hospital consisted of a 50-cent prepay each month for up to 21 days of hospitalization per year. The success of the program leads to enrollment by employees in other professions across Dallas.

History of Kaiser Permanente

After World War II ended the shipyard workforce fell from 90,000 to 13,000. Only 12 of 75 medical group providers remained. On July 21, 1945, the Permanente Health Plan opened to the public to continue the health care delivery set up by Kaiser and Garfield. In 10 years, more than 300,000 people enrolled in Northern California with the support of two unions, the International Longshoremen’s and Warehousemen’s Union and the Retail Clerks Union.

In 1953, the name of the health plan and the hospitals were changed from Permanente to Kaiser Permanente. Even today, there are ties between the nonprofit Kaiser Foundation Health Plan and Hospitals and the Permanente Medical Groups.

If your health plan benefits include a prepaid prescription drug plan, you must use a Kaiser pharmacy to obtain drugs at plan prices.
