Your Medicare Advantage Chronic Special Needs Plan (C-SNP) is tailored to help you receive specialized care for your specific health condition. But what happens when that changes? Most people maintain C-SNP eligibility while they’re on Medicare, because most of the conditions are lifelong — but not all of them are. And many Medicare Advantage plans change at least slightly each year.
If you’re newly eligible for a plan, concerned you may no longer be eligible, or worried about potential plan changes in 2027, read on to find out how to maintain the coverage you need next year.
Can you lose eligibility for a C-SNP?
Yes, there are a few ways you can lose eligibility for a C-SNP, but losing eligibility isn’t very common. Here are three scenarios in which you can lose C-SNP plan eligibility.
- If you don’t provide all required information within the carrier’s timeframe after enrollment, your application expires. Most plans have an enrollment team that reaches out to get verbal or written attestation that you have the chronic condition. They confirm this through your healthcare provider. Your doctor needs to respond to the carrier (usually within 60 days) to complete your application. If the carrier can’t confirm your condition, you’ll be dropped from the C-SNP.
- C-SNP plans are meant for people with chronic conditions, most of which last for life. If your plan requires active management for your condition and you no longer need that kind of care, you could lose eligibility. For instance, you may have diabetes that gets resolved well enough that you no longer need full-time management, or you fully recover from a stroke.
- If you move out of the area where the C-SNP is located, you lose the plan. You’ll have to find a new plan in your location.
What happens if you lose C-SNP eligibility?
If you aren’t eligible for your C-SNP anymore, your plan will send you a written notice within 10 days of determining that you don’t meet eligibility requirements. If you think you should still be eligible, follow these steps:
- Reapply with a broker to regain eligibility (often you have between 30 days and six months, depending on the carrier)
- Reach out to your carrier to understand their appeal process.
- Talk with your doctor and get a signed statement saying you’re actively managing your qualifying condition.
- If you still lose your coverage, you’ll have a Special Enrollment Period during which you can change your Medicare plan. The Special Enrollment Period begins when you lose C-SNP eligibility and lasts through the end of that month and for two months afterward.
Before you lose your plan, review your health status and different Medicare plans to understand which new plan would be best for you. You can change to:
- A standard Medicare Advantage plan,
- A different C-SNP if you qualify,
- Original Medicare with a Part D drug plan.
Can you enroll in a C-SNP anytime?
When you’re diagnosed with an eligible chronic condition, you qualify for a C-SNP enrollment period. This means you can enroll any time during the year – you don’t have to wait for Annual Enrollment. You’ll have an initial enrollment period for each chronic condition that qualifies.
One note to remember: Your C-SNP initial enrollment period only lasts until you enroll in a plan. Once you’ve chosen a plan, you’ll have to stick with it until the next Annual Enrollment Period (October 15 to December 1) or Medicare Advantage Open Enrollment (January 1 to March 31).
How C-SNP plans can change year to year
Your Medicare Advantage C-SNP plan is offered by a private insurance carrier, and many carriers update their plans each year. Carriers make changes based on rising healthcare costs, government funding they receive, drug costs, and contracts with local healthcare providers. This could mean you’ll have changes to:
- Provider networks,
- Out-of-pocket costs for services,
- Monthly premiums, annual deductibles, and out-of-pocket maximums,
- In-network pharmacies,
- Drug formularies,
- Specific C-SNP benefits like meal delivery, grocery cards, or transportation benefits.
To understand your plan changes in 2027, make sure to look over your Annual Notice of Change (ANOC). Your carrier will send your ANOC in September with all the information you’ll need to determine if your current plan is right for you.
What to do if your C-SNP situation changes
Being diagnosed with a chronic condition can be stressful. It’s not the time to worry about whether your health plan is going to support your new care needs. If you’ve recently become eligible for a C-SNP plan, lost eligibility, or your plan is undergoing major changes, you don’t have to figure out your next steps alone.
