Choosing the Right Health Plan During Open Enrollment
A guide for patients with rare and chronic conditions
Health Plan Types
HMO: Health Maintenance Organization
How it works
You must choose in-network doctors and usually need a referral from a primary care physician, or PCP, for specialists.
Pros
Usually lowest monthly premiums
Lower out-of-pocket costs
Strong care coordination when the network is good
Predictable cost structure
Cons for chronic or rare disease patients
Severely limited specialist networks
Referral bureaucracy
Difficulty accessing out-of-network experts
Appeals can be slower because decisions are tightly controlled
Rare disease centers often are not included
Best for: Patients with stable conditions who already have an established in-network team and do not require out-of-state specialty care.
PPO: Preferred Provider Organization
How it works
Allows in-network and out-of-network care with no referrals required.
Pros
Most flexible option
No referral barriers
Access to out-of-network specialists and academic medical centers
Ideal for multi-specialty care, rare disease evaluations, and second opinions
Cons for chronic or rare disease patients
Higher monthly premiums
Higher deductibles and coinsurance
Out-of-network coverage may still be expensive
Best for: Complex, rare, or unstable conditions; people who need access to specialists across multiple systems; and patients who frequently need second opinions.
POS: Point of Service
How it works
A hybrid of an HMO and PPO. It requires a PCP and referrals but allows out-of-network care at a cost.
Pros
More flexibility than an HMO
Some out-of-network options
Usually mid-range premiums
Cons for chronic or rare disease patients
Referral requirements slow everything down
Out-of-network benefits are often weak
Not ideal for high-complexity care
Best for: Patients whose care is mostly in-network but who want some options beyond an HMO.
EPO: Exclusive Provider Organization
How it works
Like a PPO but without out-of-network coverage except for emergencies.
Pros
Lower premium than a PPO
No referral requirements
Simpler than HMOs
Cons for chronic or rare disease patients
No out-of-network coverage, which creates a significant risk for rare disease care
Rarely contracts with specialty centers
Can trap patients in a narrow network
Best for: Patients whose entire care network is in-network and who do not anticipate rare disease referrals.
HDHP: High Deductible Health Plan
How it works
A plan with a very high deductible that may be eligible for a health savings account, or HSA.
Pros
Low premiums
HSA tax advantages
Can work for people who use very little care
Cons for chronic or rare disease patients
Almost never appropriate
You may have to pay thousands of dollars before the plan pays anything
Can create care delays
High upfront costs for medications, labs, and imaging
Best for: Individuals with excellent health and minimal healthcare use.
Not recommended for chronic illness or rare disease patients.
Factors You Must Evaluate
A. Insurance Network and Specialist Access
Look specifically for
Your current specialists
Academic medical centers
Rare disease centers of excellence
Neurology, rheumatology, immunology, gastroenterology, autonomic, genetic, and pain specialists
Red flags
A plan where specialty clinics bill as Tier 3 cost-share
Plans that exclude centers of excellence
Networks with only one rheumatologist or neurologist
B. Medication Coverage: Formulary Review
Checklist
Are your current medications covered?
Are they Tier 1, Tier 2, Tier 3, or specialty tier?
Are there quantity limits or step therapy requirements?
Do you need prior authorization for every refill?
Red flags
Plans where most of your medications are non-formulary
Tier 4 copays that exceed $150 to $400 per month
Mandatory step therapy before your current treatment
C. Durable Medical Equipment Policies
Important for patients using
Feeding tubes
Mobility aids
Continuous glucose monitors, or CGMs
Oxygen
Infusions, ports, or peripherally inserted central catheter supplies
Compression garments
Red flags
DME vendors restricted to a single supplier
Annual limits
Coverage only for temporary conditions
Non-coverage for wheelchairs or specialty mobility devices
D. Therapy Limits
Includes
Physical therapy
Occupational therapy
Speech therapy
Mental health care and psychotherapy
Red flags
Annual visit caps, such as 20 physical therapy visits per year
Non-covered conditions; many plans exclude chronic pain, ME/CFS, or EDS
Requirements for reauthorization every six to eight visits
E. Diagnostic Testing Flexibility
Patients who need ongoing testing should verify
Imaging policies for MRI, MRA, and CT scans
Genetic testing coverage
Specialized lab tests
Out-of-network flexibility for rare lab panels
Red flags
Experimental or investigational denials for necessary specialty tests
Only one or two contracted imaging centers
F. Out-of-State or Multi-State Care Needs
Relevant for patients receiving care from
Mayo Clinic
Cleveland Clinic
Stanford
Children's Hospital of Philadelphia, or CHOP
Rare disease or dysautonomia centers
Prioritize
PPO plans
Multi-state networks
Avoid
HMO plans
EPO plans
Regional plans with narrow networks
Exclusions and Limitations That Hurt You the Most
Avoid choosing a plan with these features when possible:
Annual caps on physical or occupational therapy
No out-of-network coverage when you rely on specialty care
Prescription exclusions for injectables, infusions, biologics, GLP-1 medications, migraine medications, or immunology medications
Coverage only for acute conditions
DME exclusions for chronic conditions
Lack of mental health parity
No coverage for telehealth or out-of-state telehealth
Plans filed under different states, such as ERISA plans filed in New York but sold in Colorado, because state protections may not apply
Choosing a Plan Based on Your Financial Reality
A. Understand the Four Financial Components
Premium: What you pay monthly
Deductible: What you must pay before insurance begins paying under the plan's terms
Copays and coinsurance: What you pay when you receive care
Out-of-pocket maximum: The most you can spend in a year on covered, in-network services that count toward the limit
For chronic illness patients, the out-of-pocket maximum is often the most important number.
B. Match a Plan to Your Financial Situation
If your healthcare use is very high
Choose a plan with:
A low deductible
A low out-of-pocket maximum
A higher premium
Why: You may reach the out-of-pocket maximum early, after which the plan may pay 100 percent of covered, in-network services for the rest of the plan year.
If you rely on many specialists across systems
PPO coverage
A large national network
A reasonable out-of-pocket maximum
Flexible telehealth and second-opinion benefits
If you use expensive medications, including biologics, infusions, or rare disease medications
Prioritize:
Plans that cover your medication
Specialty tiers with capped copays
No mandatory step therapy
Avoid plans with high coinsurance percentages. Ten to 50 percent of a $5,000 medication may be unaffordable.
If cash flow is a limitation
Look for a lower monthly cost with a still-reasonable deductible
Prefer copays instead of coinsurance
Look for predictable care costs
Avoid HDHPs unless truly necessary
If you have unstable symptoms or a risk of hospitalization
Focus heavily on:
The out-of-pocket maximum
Emergency department cost structure
Inpatient hospitalization copays
Access to specialists who can help prevent hospital admissions
How to Make a Decision
Step 1: List Your Non-Negotiables
Essential specialists
Medications
Durable medical equipment
Hospitals and health systems
Diagnostic needs
Step 2: Run Each Plan Through This Filter
Are my specialists covered?
Are my medications on the formulary?
Will my durable medical equipment be covered?
Is my hospital system in-network?
Does the plan offer out-of-network flexibility?
Does the plan have exclusions that directly affect me?
Can I afford the out-of-pocket maximum if I have a bad year?
Would I still have access to out-of-state or rare disease care?
If a plan fails more than two of these tests, eliminate it.
What to Do if All Your Plan Options Fail the Tests
A. Rank Your Medical Priorities in Order of Danger
Ask which failures would cause the most harm to your health or finances.
Medication access. If necessary medications are not covered or require step therapy, this is the biggest red flag. Lack of coverage for biologics, infusions, immunology medications, migraine injectables, cardiac medications, or GLP-1 medications can destabilize health quickly.
Specialist access. If losing your specialists could result in hospitalization, a severe flare, or delayed treatment, prioritize a plan that keeps the most critical specialists.
Hospital system access. If you rely on a specific hospital for neurosurgery, GI motility care, EDS surgery, or autonomic care, choose the plan that keeps that system in-network.
Out-of-pocket maximum. If you know you will reach the maximum, consider choosing the lowest one available even if the premium is higher.
DME and therapy coverage. Feeding tubes, wheelchairs, PT, OT, infusion supplies, CGMs, and home medical equipment must remain covered.
Diagnostic testing flexibility. If imaging or specialty labs are essential, prioritize the plan that covers the most options even if the network is limited.
You are choosing based on what would destabilize your health the fastest.
B. Pick the Plan With the Fewest Catastrophic Barriers
When all plans are bad, choose the one that avoids catastrophic outcomes such as:
Losing access to a life-sustaining medication
Losing your most important specialist
Being unable to afford care until reaching a $7,000 to $10,000 deductible
Losing non-negotiable DME or supplies
Lacking access to a hospital that can manage your specific disease
If a plan has flaws but is less likely to severely destabilize your health, it may be the least harmful option.
C. Prepare an Appeal Strategy Before the Plan Year Begins
If you are forced into a restrictive plan, prepare your appeal toolkit before January 1:
Letters of medical necessity from each specialist
Medical records documenting failed treatments for step therapy
Specialist notes supporting the need for out-of-network care
Rare disease guidelines supporting treatment at specialty centers
Prior authorization templates ready to submit
An organized medical binder or digital file system
This may increase your chances of approval after the new plan begins.
D. Use Employer Leverage if the Plans Are Unsafe
1. Request a one-off accommodation or exception
Ask human resources about:
A plan exception for a specialty medication
A disability-related accommodation under the ADA
An alternative formulary tier
A coverage exception for out-of-state specialists
2. Educate HR about plan deficiencies
Many HR departments do not understand rare disease, immunology, complex care coordination, or the effects of limited networks. Providing a specialist letter, medical summary, and formal accommodation request may shift the outcome.
3. Use the ADA or disability accommodation pathway
If a health plan removes coverage for a disability-related medication, restricts medically needed specialty care, or eliminates access to medically required equipment, you may be able to request workplace accommodations or file a disability discrimination complaint. Legal requirements vary; professional legal guidance may be necessary.
E. Evaluate External Options When Legally Allowed
1. Marketplace or ACA plans
Some families may be able to decline employer insurance and purchase coverage through a marketplace. Eligibility for financial assistance and affordability rules change over time. Review current federal and state requirements before making a decision.
2. Medicaid or Medi-Cal
Coverage may be available when income or disability-related eligibility requirements are met.
3. Dual coverage
A spouse's plan, Medicaid, or Medicare may sometimes serve as secondary coverage to fill gaps.
4. Patient assistance programs
These programs may help with high-cost medications that are not covered.
Important: Some ERISA employers may restrict dual enrollment or reimbursement for outside plans. This must be evaluated case by case.
F. If the Plan's Weakness Is Strictly Financial
Choose the plan with:
The lowest out-of-pocket maximum
The most predictable copays
The lowest coinsurance percentages
The best specialty medication coverage
Access to your highest-cost specialists
Avoid:
High-deductible plans
Coinsurance-based specialty tiers
Plans with no out-of-network coverage when you need specialists
Plans whose formularies exclude many of your medications
G. If All Plans Are Equally Harmful, Choose Based on Survival Priorities
Medication access
Out-of-pocket maximum
Access to your most critical specialist
Hospital network
DME and therapy limits
Diagnostic testing access
Medication access, specialist access, and the out-of-pocket maximum generally matter most. Other barriers may sometimes be addressed through appeals, peer-to-peer reviews, or exceptions.
H. Use This Tie-Breaker Question
Which plan gives me the best appeal pathway?
The original guide suggests the following general hierarchy:
PPO > POS > HMO > EPO > HDHP
Appeal rights and protections vary by plan type, funding arrangement, employer, state, and federal law. Review the actual plan documents and applicable rules.
