Mutual of Omaha boasts about paying 98% of Medicare Claims within 12 hours, meaning you don’t need to worry about claim status!

Then, there are household discounts up to 12% for beneficiaries that live with someone over 60 for at least a year. There is also a spouse discount for those with a spouse that has an active Medigap policy with the same Mutual company.

Of course, discounts vary by state. Either way, you can’t go wrong when you go with Mutual of Omaha.

  1. Two questions: (1) Can companies that offer supplement plans deny enrollment on the basis of pre-existing conditions? (2) I am thinking of switching from my Plan J (no longer offered) to a different plan. Is it still true that i can get a plan with the same or fewer benefits, but not one with more benefits? I have had original medicare since 2005. Thanks.

    1. Hi Mary! Thank you for your questions! 1) Yes, supplement companies can deny you coverage due to pre-existing conditions when enrolling outside of your Medigap Open Enrollment Period. 2) Plan J was discontinued because it essentially was the same plan as Plan F, which is the plan that offers the most benefits. You’re eligible to switch to Plan F or any other plan of your choice. However, unless you have state-specific rules that apply to Plan J, you will still have to answer health questions to switch to a different Medigap plan. You could be denied coverage due to a pre-existing condition. Keep in mind, not all carriers will deny you for the same reasons. Just because one carrier denied your coverage doesn’t mean all of them will. I would recommend giving us a call. We can pull all the plans in your area and determine if any pre-existing conditions you have will impact your approval odds. You may find that Plan F has a lower premium than your current Plan J.

  2. I am thinking of having knee replacement surgery. Right now I’m just getting shots every 3 months. They don’t last that long but they do help. My insurance is Humana Choice (PPO). Do you or can you tell me what my out of pocket cost will be if I have the surgery. Or a ball park number. I live in Waco, Tx. I just left my DR.s office. We talked about it and he told me to think about it. If I opt not to have the surgery I can continue with the shots. I would like to have some idea what it would cost me.

    1. Hi Diana! Humana Choice is an Advantage plan. The carrier is who determines how much you will pay out of pocket, it’s not standardized by the federal government like Medicare Supplement plans are. You will need to contact Humana directly to find out how much your out of pocket costs will be for knee replacement surgery. Unfortunately, there is no way for us to look it up for you.

  3. I know that many people still question is United Medicare Advisors a reputable company. Such rating may help better understand the market.

  4. My husband and I currently have Mutual of Omaha Plan G. Rates are going up 16%. Tried switching to Aetna. Was declined due to either my one med, flecainide or my ablation a year ago. Is there an insurance that we could get? Same plan but certainly lower premiums.

    1. Hi Judy! Some carriers will deny you for a reason that another carrier would not. Your best option is to give us a call so we can pull up all the carriers that offer Plan G in your area. Each carrier offers different plans in each state. Our agents will know which carriers will deny your policy for taking those medications & which carriers would approve your policy.

  5. Do these supplemental plans cover Milrinone since our Medicare plan has a $16.58 per day co-pay which we cannot afford

    1. Hi Cynthia! Is Milrinone administered at the doctors’ office? If so, that would probably be covered under Part B. I’m thinking the $16.58 is the 20% copay you’re left responsible for. If this is the case, then yes, a Medigap plan would cover that 20% copay. Any medication taken at home would be covered under Part D.

  6. My wife is 65 and will be as of 12/25/2018. we live in Idaho 6 months and Mississippi 6 months. Humana choice is what we currently have. half the time we are out of network with our insurance. looking for a F plan with 0 copay and deductible, could you please adise.

  7. My husband is retired military with Tricare for Life on both of us as secondary to our required by social security Medicare parts A&B. Who has the best supplement for us to cover dental, vision, hearing.

    1. Hi Joyce! That depends on many factors, like your location. If you give us a call, we’ll be able to collect the information needed to provide you with the carriers that offer dental, vision, and hearing in your area.
