Shield versus United Healthcare(R) versus Anthem Medigap Plans in California



These three make up probably 95% of the medigap market and for good reason.


A recent change in discounts has now made the playing field even more level.


How do we compare these three carriers to find the best value and what's the real difference in the day-to-day interaction with them?


With 25+ years experience across all three (and others), we'll bring you the full picture with our credentials here:



Let's cover these differences:


  • What's the difference between Shield, United Healthcare(R), and Anthem for medigap
  • Who is best priced with Shield versus United Healthcare(R) versus Anthem for supplements
  • How to quote Shield, United Healthcare(R), and Anthem for your situation
  • How to apply or switch medigap plans between Shield, United Healthcare(R), or Anthem

Let's get started!


What's the difference between Shield, United Healthcare(R), and Anthem for medigap

Before we jump into the differences, let's discuss how medigap levels the market.


The rules that govern how medigap plans work are Federal which means that a given plan (say the G plan - most popular) will walk and talk the same way regardless of the carrier.


  • Benefits are standardized across Shield, Anthem, and United Healthcare(R)
  • The doctor/hospital network is identical across all three carriers - any providers that takes Medicare
  • Medicare determines what is an allowable expense; carrier just picks up their share


So...the core process of medigap plans will be identical between the three carriers. This makes it so much easier to compare versus individual/family plans or Advantage plans.


Then what's different?


Pricing! It's amazing to us how wide the price spread can be for the exact same plan!


Identical benefits. Huge swings in pricing.



We'll look at this below.


Then there's just dealing with the carriers.


The customer service side of things is pretty comparable between the three.


Keep in mind that Medicare is a whole separate segment of the company. You can't really look at past interactions (CoveredCa, employer plans, etc) since those are almost different companies within each carrier.


Again...with 25+ years experience, we see very little different in customer service between the three for medigap plans.



As for the broad strokes:


  • United Healthcare(R) is the actual carrier. Your actual interaction will be with them for the health insurance piece of it.
  • Blue Shield is a non-profit carrier with decades experience in the Medigap.
  • Anthem Blue Cross is a separate carrier from Blue Shield and operates as a for-profit entity (no bearing on pricing as we'll see below).


Shield and Anthem are the two old players in the medigap market and United Healthcare(R) is just a nationwide juggernaut due to their marketing prowess.


In the end..it comes down to pricing! Let's go there.


Who is best priced with Shield versus United Healthcare(R) versus Anthem for supplements

We work with all three and we can't stress this enough.


You MUST quote the plans annually to make sure you're not overpaying for the exact same benefits.


There's an interesting situation where a given carrier is best priced for the same plan at one age but another carrier is better priced at a different age.


Some carriers try to focus on specific plans (G or N for example) as well.


Let's take some examples.


First, Los Angeles, age 65!


Okay...so United Healthcare(R) and Blue Shield are nearly identical at age 65.


Keep in mind that all three now have a $25/month first year "New to Medicare" discount.




Let's go up to age 70!


Wow. Shield is now almost $250/year more than United Healthcare(R)'s plan for the exact same benefits.


See why we have to be on top of this.


We can do the work for you. Just email us your date of birth and zip code or run your quote below. We'll run the numbers across all the major carriers.


The N plan (next most popular plan) is even more extreme in price swings!


That's almost $500/year difference between lowest/highest for the same plan.


And 10's of 1000's of seniors are probably paying this difference! They're all giant carriers with lots of members.


Again, our favorite pastime is helping people find savings for the same core benefits.


What about quoting yourself?


How to quote Shield, United Healthcare(R), and Anthem for your situation


We make this easy.


You can run your quote here across the major carriers (we'll send United Healthcare(R) separately and do a full proposal for you to make sure there's no better option).

More importantly, we'll hand-walk you through the process and help with any questions at ZERO cost to you.


Medicare has a language all its own so lean on our 25+ years experience.


We can technically apply for medigap plans (or changes) any time of the year.


Once we're outside our open enrollment window, it is subject to health but we can take advantage of the birthday rule to change plans to a equal or lesser plan.


That means if we're on a more expensive G plan say with Shield, we could move to United Healthcare(R) around our birthday.


We can help you take advantage at this and there's zero cost for our assistance!


It should be clear that with United Healthcare(R), Shield, and Anthem, it's really a question of pricing and the market needs to be re-quoted periodically to make sure we're not just lighting money on fire (examples above!!).

▸ Can I switch Medigap carriers in California without medical underwriting?
California's Birthday Rule generally allows you to switch to an equal or lesser-benefit Medigap plan within a 60-day window around your birthday each year, without answering health questions. This is a valuable California-specific protection not available in most other states.
▸ Does it matter which carrier I choose for a Medigap plan if the benefits are identical?

▸ Can I see any doctor with a Blue Shield, United Healthcare, or Anthem Medigap plan?
Generally, yes - most Medigap plans allow you to see any provider nationwide who accepts Medicare, regardless of which carrier issued your supplement policy. This is a key advantage over Medicare Advantage plans, which typically use restricted networks.
