H0524-003 Medicare Plan Guide: Primary Care Coverage in 2026

Key Takeaways

• H0524-003 is a Kaiser Permanente Medicare Advantage HMO plan identifier serving five California counties; always verify your ZIP code eligibility and confirm plan details in official documents before enrolling.
• The plan reports $0 premiums, deductibles, and copays for in-network primary and specialist care, plus a $699 yearly out-of-pocket maximum, but you must still pay your Part B premium separately.
• As an HMO, this plan requires using in-network providers; confirm your doctor's network status directly with their office and the insurer, as directories can be outdated and out-of-network care may not be covered.
• Supplemental benefits include dental, vision, hearing, fitness programs, and a $50 quarterly OTC allowance, but each has limits and caps that you should review in the Evidence of Coverage.
• Your primary care physician coordinates all care and referrals in an HMO; use your $0 annual wellness visit to review health goals, medications, screenings, and vaccines tailored to your age and risk factors.
• Plan costs and coverage change yearly, and third-party listings can be outdated; always cross-check reported benefits against Medicare Plan Compare and official plan documents for your specific situation.

If you have seen the code H0524-003 on a Medicare notice, plan listing, or insurance card, you are probably wondering what it means. It is a plan identifier tied to Kaiser Permanente Senior Advantage LA, Orange Co., a Medicare Advantage HMO with prescription drug coverage. The code matters because it tells you which plan you are on, and that shapes how you get primary care, wellness visits, and preventive screenings.

Many people search this code when they are comparing plans, checking benefits, or asking whether their doctor is in the network. This guide explains what H0524-003 is, what 2026 listings report about its costs and benefits, and how to confirm the details for your own ZIP code. It also covers how primary care fits into a Medicare Advantage HMO and how to plan your preventive care. Plan details can change every year, so always verify facts with official plan documents.

What Is H0524-003?

H0524-003 is a CMS plan identifier for an individual Medicare Advantage (Part C) HMO that includes prescription drug coverage. Insurers call this type of plan an MAPD. The same code may also appear as H0524-003-0 or H0524-003-000 in third-party listings.

The code breaks down into simple parts:

• H0524 is the contract number that CMS assigns to the insurer's plan contract.
• 003 is the plan benefit package number under that contract.
• The final digits (such as -0) often mark a plan segment, which relates to a specific service area.

Knowing this helps you avoid mixing up similar plans. Two plans from the same insurer can look alike but have different premiums, networks, and benefits. The plan number is the most reliable way to tell them apart.

Who Can Enroll and Where Is the Plan Offered?

Third-party 2026 listings report that this plan serves five California counties: Los Angeles, Orange, Kern, San Bernardino, and Ventura. Eligibility generally requires the following:

1. You must have both Medicare Part A and Medicare Part B.
2. You must live inside the plan's service area.
3. You must meet any other enrollment rules that CMS and the plan set for the year.

Availability can vary by ZIP code and plan year. Before you rely on any listing, check the plan's service area on Medicare Plan Compare or with the insurer directly. Also note that this plan is tied to California counties. If you live in Florida, you would look at Medicare Advantage options offered in your own area instead.

2026 Costs Reported for H0524-003

Third-party listings for 2026 report the figures below. These numbers can change, so treat them as a starting point and confirm them in the official Evidence of Coverage.

The $699 maximum out-of-pocket amount is a yearly limit on covered in-network Part A and Part B services. It does not cap your premiums, care the plan does not cover, or all of your drug spending. Prescription costs depend on the plan's formulary and coverage rules.

Supplemental Benefits Reported for 2026

Beyond basic Medicare coverage, listings report several extra benefits. The exact limits and covered services vary, so check each one before you count on it.

• Prescription drug coverage through the plan's formulary
• Dental, vision, and hearing benefits
• Fitness benefit and health education programs
• Over-the-counter allowance, reported at $50 every three months in one 2026 listing

These extras can add real value, but they often come with limits, such as annual caps or approved product lists. Read the fine print in the plan documents so you know what is and is not covered.

How an HMO Affects Your Primary Care

H0524-003 is an HMO. In general, that means you use the plan's network of doctors and facilities. Some services may need a referral or prior authorization. Emergency and urgent care follow different access rules, so review the Evidence of Coverage for details.

An HMO works best when you have one main doctor who knows your history. Your primary care physician coordinates your care, orders screenings, manages prescriptions, and refers you to specialists when needed. If you want to understand how that role works, read about how to use a Medicare HMO for better primary care. It also helps to know whether you need a referral with a Medicare HMO in 2026.

The listings say the plan covers primary care and specialist visits with a $0 copay. That sounds simple, but a $0 copay only applies to in-network care. Seeing an out-of-network provider can lead to higher costs or no coverage at all. That is why checking your doctor's network status is one of the most important steps you can take.

How to Check Whether Your Doctor Is In-Network

Follow these steps before you enroll or use your benefits:

1. Get the exact plan name and number. Use H0524-003 so you do not confuse it with another plan.
2. Search the provider directory. Use the insurer's online directory for your county.
3. Call the doctor's office. Ask whether they accept this specific plan today. Directories can be out of date.
4. Confirm with the plan. Call member services to verify network status in writing if you can.
5. Check prior authorization rules. Ask which services need approval before you go.

Using Your Annual Wellness Visit Well

A $0 annual wellness visit is one of the best values in Medicare. It is a chance to review your health, set goals, and catch problems early. It is not the same as a full physical exam, and many people mix them up.

To get the most from your visit:

• Bring a list of all medicines and supplements.
• Write down symptoms, even minor ones.
• Ask about screenings that fit your age and risk level.
• Review your vaccines and family history.
• Discuss sleep, mood, diet, and activity.

To learn more, see what happens during an annual wellness visit and the common Medicare wellness visit mistakes to avoid.

Preventive Care Matters More Than the Plan Code

A good plan is only useful if you use it. Preventive care helps you find problems early, when they are easier to treat. Many Medicare-covered preventive services are reported at $0 in-network on this plan, but you should confirm each one.

Common preventive steps include:

• Blood pressure and cholesterol checks
• Diabetes screening
• Cancer screenings, based on age and risk
• Vaccines
• Bone density and fall-risk reviews

Our guides on making preventive care work for your health and which screenings adults should get every year can help you plan.

Understanding Medicare Star Ratings

Medicare rates plans on a five-star scale. The ratings look at care quality, member experience, and customer service. A Kaiser Permanente 2026 Star Ratings document exists for contract H0524. However, the available excerpt does not give a reliable numeric rating for this specific plan. Check the current plan-level rating on Medicare Plan Compare before you decide.

Common Mistakes When Reviewing a Medicare Plan Code

People often make avoidable errors when they research a plan number. Watch for these:

• Relying only on third-party listings. They can be outdated. Use official plan documents as your final source.
• Ignoring the service area. A plan may not be offered where you live.
• Assuming $0 means free everything. Copays apply only to in-network, covered services.
• Skipping the drug formulary. Your medicines may have restrictions or tiers.
• Forgetting the Part B premium. You still pay it in addition to any plan premium.
