Appoint a Representative

You have the right to appoint someone to represent you in medical matters (such as a family member, friend or other trusted person). A representative can contact HPSM on your behalf, get information about your benefits and make decisions about your medical care. If someone contacts HPSM claiming to be your representative, we will check our records to confirm their status before sharing your health information or taking any action.
