Why do some ZIP codes get better Medicare Advantage benefits than others?
Answered by 6 licensed agents
Carriers file their plans by county and zip code and there are specific benchmarks (thresholds) that carriers (private companies administering the Medicare program (Parts A and B) must meet as a managed care organization. Each carrier files their cost to administer the plan and care for the members with the Medicare and if the government funding (in the form of rebates ) paid to the carrier exceeds the allowed threshold, they are required to return the excess in the form of "extra benefits" to the beneficiaries.
Example:
If you have ever seen a carrier give a Part B Rebate of $2-3 dollars and thought it was silly, it is because they can't keep the excess amount. They are required to return it to the members and the cost to purchase another benefit (cost per member per month) is more than the remaining amount of 2-3 dollars, they will give to the members in the form of a Part B Rebate.
Just like the Cost of Living (COL) is variable by geographical location, so are the cost associated with administering the plan of care and the Medicare benefits. Therefore, you will see different benefits (less, more, or better) from the same carrier and sometimes the same plan name in different areas of the state and country.
Great question that I'm sure other members also have and just haven't asked yet. Thank you!

The benefits available in each area can vary based on several factors, including Medicare financial support to the plan, local healthcare costs, provider contracts, competition between plans, and the needs of that particular market. Each carrier also weighs and uses these factors differently when designing its plans and benefits.
That is why someone in one county may have access to lower copays, better dental benefits, or other extras that are not available just a few miles away. And why two carriers serving the same county may offer very different benefits.
As an agent, I don't assume one area, carrier, or plan is automatically better. I look at what is actually available where you live and then compare the benefits, doctors, prescriptions, and overall fit for your healthcare needs.

The cost of living in one area can affect the cost of doctors' visits, hospitalization costs and malpractice insurance rates.
Regional and cultural factors like smoking, diet and exercise can affect the cost of healthcare in an area which then get passed to you the insured.
The number of providers like doctors, medical groups and hospitals can affect the ability for Advantage plans to offer good benefits.
All this effects the cost of a Medicare Supplement plan as well.
