LMN Requests

Built with

Once your LMN has been issued, certain information on it can be updated if something isn’t quite right. Every change request goes through a brief review by a licensed clinician on Truemed’s provider network to make sure your documentation stays compliant. Below are the most common update scenarios and what to do in each case.

1. Incorrect diagnosis / medical condition

If the diagnosis listed on your LMN doesn’t accurately reflect your condition, you can request a review. Diagnosis changes are not automatically approved. A licensed clinician will need to evaluate the new information before any update is issued.

To request a diagnosis correction, contact Truemed support at support@truemed.com and include:

  • Your name and the email address tied to your Truemed account
  • The diagnosis currently listed on your LMN
  • The correct diagnosis or condition you’d like documented
  • Any additional context that supports the change

In some cases, you may be asked to retake the clinical intake survey so the reviewing clinician has complete, up-to-date information to work with.

2. Incorrect merchant

Each LMN is tied to a specific merchant. If your LMN lists the wrong merchant, it cannot be transferred or reassigned. You’ll need a new LMN issued for the correct merchant.

Reach out to support@truemed.com with your account details and the name of the merchant your LMN should have been issued for. The support team will let you know whether a corrected LMN can be issued or whether you’ll need to complete a new qualification for that merchant.

3. Incorrect product(s) listed

If the product listed on your LMN doesn’t match what you purchased or if you’ve added items from the same merchant that should be included, an updated LMN can be issued.

Contact support@truemed.com and have the following ready:

  • Your name and account email
  • The product currently listed on your LMN
  • The correct product name and a brief description of what it is
  • The merchant name

The support team will coordinate the update with the reviewing clinician.

4. Correcting personal details

If your name, email address, age, or other personal information appears incorrectly on your LMN, Truemed can issue a corrected version.

Send a message to support@truemed.com with the specific details that need to be fixed. Depending on the nature of the correction, you may be asked to provide a supporting document (such as a government-issued ID) to verify the correct information before the update is made.

5. New administrator info

If your HSA or FSA administrator has changed since your original LMN was issued, Truemed can reissue your LMN on a template that matches your new administrator’s requirements.

Contact support@truemed.com and let the team know:

  • Your current administrator’s name
  • Any specific requirements your new administrator has shared with you (for example, a particular format, field, or certification language they require)

The support team will work with the reviewing clinician to get an updated version issued.

6. New template request

Some HSA and FSA administrators have specific formatting requirements that differ from Truemed’s standard LMN template. If your administrator has asked for a particular layout, additional fields, or specific language, Truemed can work with you on a custom template request.

Reach out to support@truemed.com and include any instructions or requirements your administrator has provided. If possible, attach the template or guidelines directly. The team will review what’s needed and let you know what’s possible.

7. Date change request

Truemed is not able to backdate or change the issue date on an LMN. The date reflects when you completed your clinical intake survey and was set at the time of issuance. This is a compliance requirement, since altering it would compromise the integrity of the documentation.

If you’re concerned that the date on your LMN doesn’t align with a purchase or claim, reach out to support@truemed.com. The team can help you understand what options are available and whether your administrator may have flexibility in how they handle the timing.
