You or your authorized representative may file a grievance or appeal request either verbally or in writing.
Examples of Grievances include but are not limited to:
We will notify you or your authorized representative of the decision about your grievance as quickly as your case requires based on your health status, but no later than 30 calendar days after receiving your complaint.

In order for Sonder Health Plans to process a Grievance or/and Appeal request from someone other than you (the member), your physician, your prescribing physician (Part D), or other prescriber (Part D), we must have authorization from you. You may appoint any individual as your representative by sending us an Appointment of Representative form signed by both you and the representative. A representative who is appointed by the court or who is acting in accordance with state law may also file a request for you after sending us the legal representative form. You will not need to complete an Appointment of Representative Form if you provide an equivalent written notice or other legal representation document with your request.
For instructions on how to appoint a representative, Click Here.
To appoint a representative, you or your representative should complete the form entitled: Appointment of Representative CMS – 1696 (Spanish Version)
If you need a large print version of CMS 1696, Click Here (Spanish Version).

Unless revoked, an appointment is considered valid for one year from the date the form is signed. Once the form is filed, it is valid for the duration of the appeal. Therefore, a signed form can be used for more than one appeal as long as the appeal is filed within one year of the date on the form.
In addition, there are certain individuals who can bring an appeal on your behalf, pursuant to State or other applicable laws. Such an individual, known as an “authorized representative,” may be a court-appointed guardian, an individual who has durable power of attorney, a health care proxy, or a person designated under a State’s health care consent statute.
You also can get the Appointment of Representative form on CMS’s website.
