How to help patients who receive a denial from their health plan

Health plans must provide patients and providers the reasons for denying coverage or reimbursement to patients.

Patients may receive a notice from their health plan that a service or treatment won’t be covered because it is not “medically necessary. If the patient  asks for your help to appeal the denial, and you're preparing a letter to address the medical necessity issue, the American Psychiatric Association has developed guidance on crafting a “medical necessity” letter (  

Fill out the disclosure requirement form

In addition to the patient submitting an appeal to their health plan, providers (with their patient’s permission) can use the Mental Health and Substance Use Disorder Parity Disclosure Request form ( to request more detailed information about treatment limitations or specific information about why benefits were denied. 

Note:  Submitting this disclosure request form does not replace the patient’s insurance company’s grievance and appeals process. 

If you choose to file this disclosure request form for the patient, follow these steps:

  • Fill out all required information in the form. If you need help filling it out, contact the patient’s insurance company.
  • Send it to the patient’s insurance company (they have 30 calendar days to respond).

If you don’t receive a response from the insurance company within 30 calendar days, you may file a complaint with our office.
