Non-subscription Slate flossers and floss head refills are HSA/FSA approved!

An LMN, or Letter of Medical Necessity, is like a doctor’s note. It’s issued by a healthcare provider to outline the medical reasons why a particular product or service is medically necessary for an individual's health, and qualifies your purchase to be HSA/FSA eligible. LMNs demonstrate that an expense is needed to diagnose, treat, or alleviate a medical symptom, rather than for general health or wellness purposes.

If you want to use your HSA/FSA funds to purchase Slate's products, you’ll need a Letter of Medical Necessity (LMN), and we’ve partnered with Sika to help you with this.

Certain products are eligible for purchase with HSA/FSA funds if they treat, cure, prevent, diagnose, or alleviate a medical need. For instance, items like bandaids are always eligible as they serve a solely medical purpose. However, there are “dual-eligible” products that can be used for general health and wellness or for specific medical purposes—if recommended by a healthcare provider based on your individual needs. Take iron supplements, for example; many use them to support their overall health. Yet, for someone with anemia, iron supplements become crucial. In such cases, individuals can use their HSA/FSA funds if their healthcare provider issues an LMN, recommending the supplements specifically to address their anemia.

You can request a LMN from your own dental professional and remit expenses directly to your HSA/FSA provider manually, or you can get a LMN right in the checkout process on the Slate website through Sika Health. Follow the steps above!

Your LMN is valid for one year, and will be associated with your email, so you can return to the Slate site, select the Sika payment method to utilize your HSA/FSA funds again and again.

As part of the confidential health assessment provided by Sika, you’ll be asked to share your name, contact information, date of birth, and information about the symptoms you are experiencing and your medical history. You will also verify your phone number and ask you to upload a photo ID to verify your identity. 

The information you provide in the LMN process will be kept confidential and shared only with our healthcare providers to evaluate your eligibility for an LMN. For more information, see our privacy policy.

Letters of Medical Necessity are valid for 12 months. 

Please note, LMNs cannot be used retroactively for purchases made prior to the date they are signed.

After you complete a purchase using an LMN, you will need to submit your Letter of Medical Necessity and your receipt to substantiate the purchase if you paid with your HSA/FSA or to get reimbursed if you paid with your credit/debit card. To do this:

1. Log into your HSA/FSA account on your benefit administrator’s website 
2. Find the Reimbursement or Claims section 
3. Upload your receipt and Letter of Medical Necessity

Your administrator will process and evaluate your claim. Please note that some HSA/FSA benefits administrators may incorrectly deny reimbursement, so before purchasing a product with an LMN you should consider contacting your administrator to determine if your purchases will be covered/reimbursed. You can learn more about what is eligible here. 

If you are having trouble locating your itemized receipt or LMN, please contact Sika at support@sikahealth.com

Sika’s independent healthcare provider may determine that you do not have symptoms demonstrating a medical necessity for a product or service. While you cannot use your HSA/FSA funds now, you can still use another payment method to complete your purchase on our site.
