Life in San Francisco is fast and vibrant, but navigating health insurance can be stressful, especially if you are managing current or chronic medical needs. The good news is that under the Affordable Care Act (ACA), all plans must cover preexisting conditions — but the choice can still be confusing. Here’s what you need to know, and how to easily navigate the decision.

Use a Trusted Health Insurance Agency

The state’s official marketplace is called Covered California. However, it can be tricky to navigate. To buy the best health insurance for people with preexisting conditions in San Francisco, many prefer to use a certified agency such as Health for California — think of the official marketplace as a supermarket, while an agency is your personal shopper and expert guide.

Health for California shows exactly the same plans and prices found on the official marketplace, but it curates them for you in a much more user-friendly and easy-to-navigate format. Its services are completely free to you as the customer. Through the agency, you can:

     Compare plans: View offerings from multiple insurers in one go.

     Get personalized advice: Agents can analyze your specific needs to recommend the best option, saving you hours of research.

     Simplify your application: Get assistance with every step of the application, including checking whether you are entitled to premium subsidies or Medi-Cal.

     Get year-round support: They can help you with issues long after you have enrolled.

How to Buy Insurance for Preexisting Conditions Through Health for California

Here’s how to find the right plan if you’re managing a preexisting condition:

1. Start With Your ZIP Code

Visit Health for California and enter your San Francisco ZIP code. This ensures you only see listings available in your local area.

2. Provide Basic Information

You’ll need to enter details such as your age and household size, your annual income — to calculate subsidy eligibility — and whether you currently have insurance. These details allow Health for California to show personalized options and pricing.

3. Compare Plans Side by Side

Once your quotes appear, you can assess coverage levels, prices and benefits. Plans are categorized into four tiers — bronze, silver, gold and platinum.

4. Speak with a Certified Agent

This is a key advantage of Health for California. Call and speak with a knowledgeable agent, who will review the options with you to narrow down your best options. They will consider things like your preferred doctors in San Francisco, any current medication and your medical history, making the advice completely personalized to you.

5. Complete Your Enrollment

The agent will walk you through the final application, ensuring all information is correct so you get the maximum financial benefit.

Understanding Health Insurance Plan Comparisons

When choosing between options, there are two key things to understand — plan types and different tiers within those.

Health Insurance Plan Types

The type you choose determines the overall rules of your cover. Different networks control how you access care and which doctors you can see. 

Plan Type

Description

Pros

Cons

Health Maintenance Organization (HMO)

Requires you to choose a primary care doctor and get referrals for specialists

Lower costs, coordinated care

Limited provider network and less flexibility

Preferred Provider Organization (PPO)

Lets you see any doctor, even out-of-network, without referrals

Maximum flexibility, especially for those who see multiple specialists

Higher premiums and out-of-network costs

Exclusive Provider Organization (EPO)

Covers only in-network care but doesn’t require referrals

Lower cost than PPO, simpler than HMO

No coverage for out-of-network providers, except emergencies

Point of Service (POS)

Similar to HMO but allows limited out-of-network options

Flexibility plus coordination

Can be confusing, with mid-range costs

If you already have trusted specialists in San Francisco managing your preexisting needs, a PPO plan may suit you best.

Health Insurance Plan Tiers

For San Francisco residents, where medical costs can be higher than the national average, deciding which tier to take is a crucial decision. This is what the different levels mean:

Plan Tier

Ideal For

Monthly Premium

Deductible

Out-of-Pocket Costs

Bronze

Healthy individuals with few medical visits

Lowest

Highest

High

Silver

Balance coverage for moderate use

Moderate

Moderate

Moderate

Gold

Regular doctor visits or prescriptions

Higher

Lower

Low

Platinum

Frequent medical care or chronic conditions

Highest

Lowest

Very low

For people managing ongoing health situations, silver or gold plans typically offer the best combination of affordability and comprehensive coverage. If you need a lot of medical care, a platinum plan may be the best value. However, speaking to a Health for California agent will give you peace of mind that an expert has reviewed your choices with you, including both plan type and plan tier.

Does All Insurance Cover preexisting Conditions?

Yes, all ACA-compliant options are guaranteed issue plans. That means you cannot be denied based on your medical history, nor can insurers charge you more because of it. Treatment for your requirements must be included.

A preexisting condition is any health issue you have now or have had in the past, for which you have had symptoms or treatment, with or without a formal diagnosis. Common examples include:

     Diabetes

     Asthma or COPD

     Cancer — in remission or treatment

     Heart disease

     High blood pressure

     Anxiety or depression

     Sleep apnea

The Centers for Medicare and Medicaid Services estimates up to 50% of Americans have such a condition. Before the ACA, insurers could deny coverage or raise premiums for these individuals, but such practices are now prohibited.

If you have a preexisting condition, you can be assured that choosing a plan via Health for California will fully cover your needs.

When to Enroll for Health Insurance

Every year, there is an open enrollment period for people wishing to sign up for or change their health insurance. For most Californians, this period runs from November through the end of January. During this period, you can switch plans, add or remove dependents, apply for subsidies or renew your coverage.

If you miss open enrollment, you may still qualify for special enrollment if you experience certain life changes, such as:

     Losing your current coverage.

     Moving to San Francisco from another area.

     Getting married, divorced or having a baby.

     A change of income that affects your eligibility for a subsidy.

Health for California’s system automatically checks if you qualify for special enrollment, making it easy to apply at any time you’re eligible.
