Key Takeaways
-
Medicare covers a wide range of healthcare services, but some important limitations may affect your ability to access specific providers and treatments.
-
Understanding these restrictions can help you plan ahead and avoid unexpected healthcare costs or coverage denials.
Medicare’s Network Restrictions Can Limit Your Provider Choices
Medicare gives you access to a vast network of healthcare providers, but not all plans work the same way. The type of Medicare coverage you have plays a big role in determining which doctors and hospitals you can see without paying extra.
Original Medicare vs. Medicare Advantage Networks
-
Original Medicare (Part A and Part B): You can see any doctor or specialist that accepts Medicare. There are no restrictive provider networks, but some doctors may not take new Medicare patients.
-
Medicare Advantage Plans: These often use provider networks, such as HMOs or PPOs. If your plan has a network, seeing out-of-network providers may lead to higher costs or even complete lack of coverage.
What Happens If Your Provider Leaves the Network?
-
If your doctor leaves your Medicare Advantage plan’s network, you may need to find a new provider or pay higher out-of-pocket costs.
-
Some plans allow you to continue care for a limited time if you’re undergoing treatment, but this varies.
How to Protect Yourself
-
Always confirm that your preferred doctors and hospitals accept your Medicare plan before scheduling appointments.
-
Review your plan’s network annually, as providers can change from year to year.
Prescription Drug Coverage Isn’t Universal for Every Medication
Medicare helps cover prescription drugs, but that doesn’t mean every medication is covered. Your access depends on which drugs are included in your plan’s formulary (approved drug list) and the specific rules in place.
Formularies and Tiered Drug Pricing
-
Medicare Part D and Medicare Advantage drug plans use formularies, which are lists of covered medications.
-
Most formularies are divided into tiers, with lower-tier drugs costing less than higher-tier medications.
-
If your prescription is on a higher tier, you may have to pay more or request an exception to get a lower cost.
Prior Authorization and Step Therapy
-
Some drugs require prior authorization, meaning your doctor must get approval from your plan before prescribing them.
-
Step therapy means you may have to try a less expensive medication first before the plan covers a more expensive option.
-
If a medication you need isn’t covered, you may need to request an exception, switch medications, or pay out of pocket.
How to Ensure You Have the Coverage You Need
-
Check your plan’s formulary each year, especially during Medicare Open Enrollment from October to December.
-
Ask your doctor about alternatives if your prescription isn’t covered or requires additional steps.
-
Consider appealing a coverage decision if you believe your medication should be covered.
Medicare’s Coverage of Dental, Vision, and Hearing Care Is Limited
One of the biggest surprises for new Medicare beneficiaries is that routine dental, vision, and hearing services aren’t covered under Original Medicare.
What Medicare Covers
-
Dental: Medicare only covers dental care if it’s medically necessary, such as surgery related to a covered health condition.
-
Vision: Basic eye exams, prescription glasses, and contact lenses are not covered unless related to a medical condition like cataracts.
-
Hearing: Medicare does not cover routine hearing exams or hearing aids.
How to Get Coverage for These Services
-
Some Medicare Advantage plans include dental, vision, and hearing benefits, but coverage varies.
-
Standalone dental, vision, and hearing insurance plans are available separately.
-
Some state assistance programs or nonprofit organizations help cover these costs for eligible individuals.
Planning Ahead for These Expenses
-
Budget for out-of-pocket costs if you expect to need dental work, new glasses, or hearing aids.
-
Look into discount programs or payment plans to make these services more affordable.
-
Consider Medicare Advantage plans carefully if they include these benefits, and review what’s covered before enrolling.
Skilled Nursing and Long-Term Care Coverage Has Restrictions
Many people assume Medicare will cover nursing home care or long-term care needs, but this is one of the most misunderstood areas of coverage.
What Medicare Covers
-
Short-term skilled nursing care is covered only after a qualifying hospital stay of at least three days.
-
If you qualify, Medicare covers up to 20 days in a skilled nursing facility with no copay. From day 21 to day 100, you’ll owe a daily copayment.
-
After 100 days, Medicare does not cover any further skilled nursing facility care.
What Medicare Does Not Cover
-
Long-term custodial care, such as help with bathing, dressing, and eating, is not covered under Medicare.
-
If you need ongoing care that is not medically necessary, you may have to pay out of pocket or rely on Medicaid if you qualify.
Planning for Long-Term Care Needs
-
Consider long-term care insurance or savings options to cover potential costs.
-
Look into state Medicaid programs if you anticipate needing extended care in the future.
-
Explore home healthcare options that may allow you to receive care without entering a facility.
Make Sure You’re Covered Where It Matters Most
Understanding Medicare’s coverage limitations can help you avoid costly surprises and ensure you have access to the healthcare providers and treatments you need. Take time to review your plan annually, consider additional coverage options if necessary, and stay informed about changes that may affect your access to care.
