Completing the necessary forms is a key step in the process when applying for Medicare Part B. One of the forms you’ll encounter is Form HCFA L564, which plays a crucial role in verifying whether you have group health coverage under your employer’s insurance. This verification is important as it helps determine whether you are eligible for a delay in enrolling in Medicare Part B without facing penalties.

In this blog, we will guide you through the process of completing Form HCFA L564, including what each section requires and the common mistakes to avoid. You’ll also learn how to handle situations when your employer doesn’t cooperate with providing the necessary information.

What is Form HCFA L564, and Why Do You Need It?

Form HCFA L564, also known as the Request for Employment Information, is a document used to verify health insurance coverage based on current employment when applying for Medicare Part B (Medical Insurance). It is typically required for individuals who delayed enrolling in Medicare Part B because they had employer-sponsored health insurance.

As physical therapy doctors and clinic owners, understanding the intricacies of Medicare enrollment is essential for ensuring seamless healthcare transitions for your patients. This form plays a critical role in verifying group health coverage under an employer's insurance plan, which is necessary for applying for Medicare Part B during a Special Enrollment Period (SEP).

Role in Verifying Group Health Coverage

The CMS-L564 form serves as proof of active employer-sponsored group health plan coverage. It is completed in two parts: Section A by the individual and Section B by the employer. The employer must confirm the start and end dates of the group health plan coverage, ensuring that there have been no more than eight consecutive months without coverage. This documentation is necessary to avoid late enrollment penalties when applying for Medicare Part B during a SEP.

What Happens if You Fill In an Incomplete or Incorrect Form?

If the CMS-L564 form is incomplete or incorrect, it can lead to delays in Medicare Part B enrollment. This might result in gaps in health coverage, which can be problematic for patients requiring continuous care. Additionally, incorrect or missing information may lead to late enrollment penalties, increasing the cost of Medicare premiums. Therefore, it is essential to ensure that all sections of the form are accurately completed and submitted along with the CMS-40B application for Medicare Part B enrollment.

To get the form in PDF and for more detailed information on how to fill out and submit these forms, you can visit the CMS website or consult with a Social Security representative.

Let’s elaborate on the purpose of the Form CMS-L564 in detail.

Purpose of Medicare Form CMS-L564

Understanding the role of the Medicare Form CMS-L564 is essential for managing employee benefits and ensuring smooth transitions into Medicare coverage. Here's a breakdown of its purpose:

  • Verifies Group Health Plan Coverage Under an Employer

The CMS-L564 form serves as a tool to confirm that an individual has active employer-sponsored group health plan coverage. This is particularly important for employees who delay enrolling in Medicare Part B because they are covered under their employer's health plan.

  • Required for Delay in Medicare Part B Due to Employer Insurance

When employees choose to delay Medicare Part B enrollment due to ongoing employment and employer-sponsored health insurance, the CMS-L564 form is necessary. It provides proof that they were eligible to delay Medicare enrollment without penalty.

  • Documents Proof of Group Health Plan Coverage Based on Current Employment

This form is used to document proof of continuous group health plan coverage based on current employment. It is essential for processing Medicare enrollment applications, especially during the Special Enrollment Period (SEP) after retirement or loss of active coverage.

How It Works

  • Employer's Role: You must fill out a portion of the form to verify the patient’s employment and health insurance coverage details. This includes confirming the dates of health insurance coverage and verifying that the employee was actively working during that time.
  • Submission Process: Once completed, the form accompanies the Medicare enrollment application. It acts as proof that the individual had health insurance through an employer, justifying the delayed enrollment in Medicare.

By accurately completing this form, you ensure that Medicare recognizes your employer coverage and allows for a timely and penalty-free enrollment.

Completing Form CMS-L564 requires cooperation between the applicant and their employer. Each section has specific requirements that must be met to ensure the form is accepted.

Completing Section A: Applicant's Responsibility

As physiotherapy clinicians and clinic owners, understanding the Medicare Part B application process is essential for supporting patients who are verifying their employer health insurance. The CMS L564 form plays a key role in this process by confirming current employment health coverage. Here's how you can guide your patients in completing Section A effectively:

1. Applicant includes Employer’s Name and Address

When assisting patients with the CMS L564 form, ensure they accurately provide their employer's name and address. This information is necessary for verifying their employment status and health insurance coverage. For example, if a patient is still working or has a spouse with current employment health coverage, this step is important for the Medicare application process.

2. Separate Forms for Multiple Employers

If a patient has had multiple employers since turning 65, they will need to complete a separate CMS L564 form for each employer. This ensures that all relevant employment periods are documented and verified, which is important for determining their eligibility for Medicare benefits based on their employment history.

3. Provide Details Based on Primary or Spousal Insurance

If a patient is applying for Medicare based on their own employment, they should enter their details in Section A. However, if they are applying based on their spouse's employment, they will need to provide their spouse's name and employment details instead. This distinction is important because the form is used to verify health insurance coverage through either primary or spousal employment.

For more detailed instructions on filling out the CMS L564 form, you can refer to resources like CMS.gov, which provides comprehensive guidance on Medicare applications and employer health insurance verification for the Medicare Part B application process.

Understanding the process of completing Form CMS-L564 is essential when your employees apply for Medicare. This form verifies employer health coverage, ensuring a smooth enrollment process for Medicare benefits. Here's how to ensure accuracy in the employer's section:

1. Employer Verifies Group Health Plan Details

When completing Section B of the CMS-L564 form, you must verify the details of the group health plan. This information is necessary for verifying your health coverage and ensuring that the employee meets the requirements for Medicare enrollment.

2. Filling Out the Required Information

  • Coverage Status: Confirm whether the employee was covered under the group health plan.
  • Coverage Dates: Specify the start and end dates of the health coverage.
  • Employment Periods: Provide the duration of the employee's employment with the company.

Accurate completion of these details is essential for employer contribution verification and to avoid delays in processing the Medicare application.

  • W-2 Forms: These forms provide proof of employment and income, which can be linked to health insurance coverage.
  • Pay Stubs: Pay stubs often list deductions for health insurance premiums, serving as alternative proof of health coverage.
  • Health Insurance Cards: These cards are direct evidence of health insurance coverage.

  • Submit the Application: Include the secondary evidence with the Medicare application. Ensure all documents are complete and accurately reflect the period of employment and health insurance coverage.
  • Follow-Up: After submitting the application, patients can follow up with Medicare to confirm receipt of the documents and to check on the status of the application.

Some important tips will ease the process of L564 submissions for your patients.

Important Tips for Submitting Medicare Form CMS-L564

When submitting Form CMS-L564, patients have a couple of options. They can either visit their local Social Security office in person or mail the completed form along with the required documents, such as Form CMS-40B, to the Social Security Administration (SSA). 

It's important to note that online submission is not available for this form, so ask your patients to follow the correct procedure to avoid any issues with their Medicare Part B application.

How Accurate Should the Information Be?

Medicare Part B application accuracy is essential to prevent enrollment delays. Ensure that your patients have all up-to-date details, including their personal information, employment status, and health insurance coverage. This form is used to verify employment and health insurance coverage, which affects Medicare Part B enrollment and premium costs. Inaccurate information can lead to delays or even denial of benefits, so it's essential to double-check every detail.

Double-Checking Details to Avoid Errors and Delays

To prevent Medicare enrollment delays, your patients should thoroughly review forms before submission. Here are some steps to follow:

  • Personal Information: Ensure names, Social Security Numbers, and dates of birth are correct.
  • Employment Details: Verify employer names, addresses, and dates of employment.
  • Insurance Information: Confirm the start and end dates of health insurance coverage.

Form Submission Tips: Always ask the patients to submit the form with all required documents, such as Form CMS-40B, to ensure a smooth Medicare Part B application process.

Errors on Form CMS-L564 can result in delayed or denied enrollment. Let’s explore the common mistakes below.

Common Mistakes to Avoid When Filling Out Form HCFA L564

Common HCFA L564 mistakes can easily be avoided with a bit of extra attention. Here are some tips to help prevent form submission errors:

  • Missing Signatures

Ensure that your patient and the employer sign the form as required. Missing signatures can lead to delays or rejection of the Medicare application. 

  • Incomplete Information

One of the most common errors is omitting necessary details. Ensure that all fields are filled out accurately, including personal information, employment details, and health insurance coverage periods. Incomplete information can cause delays in processing the application, leading to Medicare enrollment delays. Common omissions include:

  • Employer Information: Ensure the employer's name, address, and contact details are correct.
  • Coverage Dates: Verify the start and end dates of health insurance coverage to avoid form submission errors.
  • Incorrect Dates or Coverage Information

Mistakes with coverage dates or incorrect employer information can derail the application process. Double-check that the dates of employment and health insurance coverage are accurate. Employers often make errors in listing the start date of the current insurance carrier rather than the actual start date of the group health plan. 

  • Missed Deadlines

Timeliness is crucial when submitting Form CMS-L564. Missing deadlines can result in delays or even a loss of your patient’s Special Enrollment Period eligibility. Tell them to start the process early to gather all necessary information and documentation well in advance. 

Employers play a key role in verifying coverage details and ensuring accurate information is provided. See below for more information.

The Role of Employers in Medicare Form CMS-L564

Understanding the role of employers in completing the Medicare Form CMS-L564 is essential for guiding your patients through the Medicare enrollment process. 

Employer’s Responsibility in Verification

Employers play a key role in the Medicare verification process by completing Section B of the CMS-L564 form. Employers provide details about the employee's health insurance coverage. It includes whether the individual is already covered under the employer's group health plan, the start and end dates of coverage, and the duration of employment.

Employers are responsible for:

  • Verifying Coverage: Confirming that the employee was covered under their group health plan.
  • Providing Coverage Dates: Specifying when the coverage began and ended.
  • Signing the Form: A company official must sign the form to validate the information.

This verification is essential for Medicare to process the application and ensure there are no gaps in coverage.

What Happens if Employers Don’t Cooperate

If an employer fails to complete or return the CMS-L564 form, it can lead to delays in the Medicare enrollment process. This might cause inconvenience for your patients, as they may need to provide additional documentation or wait longer for their Medicare coverage to begin. 

While there are no penalties for employers who do not cooperate, it is in the best interest of both parties to ensure the timely completion of the form to avoid any complications.

Employer Communication

To ensure smooth and timely completion of the CMS-L564 form, here are some tips for your patients:

  • Early Notification: Inform your employer well in advance that you need the form completed. This allows them sufficient time to gather the necessary information.
  • Clear Instructions: Provide your employer with clear instructions on how to fill out the form and where to return it. You can refer them to resources like Medicare.gov for additional guidance.
  • Follow-Up: Schedule a follow-up with your employer to confirm that the form has been completed and returned.

Risks of Incomplete or Incorrect Form Submission

Your patient submitting an incomplete or incorrect form can lead to several issues that impact both the patient's health coverage and financial situation. Let’s review what they are below:

  • Impact on Medicare Part B Enrollment
    • Delays in Coverage: Incomplete or incorrect forms can cause delays in Medicare Part B enrollment. This means patients may not have access to necessary medical services until the issue is resolved, potentially affecting their health outcomes.
    • Penalties and Denial: Errors in the form can result in Medicare Part B penalties. If the form is not completed correctly, patients might face denial of Part B enrollment or incur penalties for late enrollment. These penalties can increase premiums by up to 10% for each full 12-month period of delayed enrollment, which can remain in effect for as long as the patient maintains Part B coverage.
  • Financial Implications
    • Late Enrollment Penalties: Missing the enrollment period due to form errors can lead to financial costs. Patients may end up paying higher premiums for Medicare Part B, which can strain their budget.
    • Loss of Benefits: Delays or denial of enrollment can also mean missing out on benefits that Medicare Part B provides, such as coverage for outpatient services essential for ongoing care.

What are the Steps to Resolve Errors?

If errors are discovered in the submitted form or if employer details are missing, your patients can:

  • Contact the Employer: Reach out to the employer to correct any inaccuracies in the form. Ensure that all required information is filled out correctly, including employment dates and health insurance coverage details.
  • Amend the Form: If the form has already been submitted, contact the Social Security Administration to request guidance on how to amend it. They can provide instructions on submitting corrections or additional documentation.
  • Seek Assistance: If you're unsure about the process or need help resolving errors, consider consulting with a Medicare representative or a healthcare advocate who can guide you through the process.

By taking proactive steps to ensure the accuracy of the CMS-L564 form, you can help your patients avoid errors in HCFA L564 and the associated risks, ensuring they receive timely and uninterrupted Medicare Part B coverage.
