Contact HICAP for help with Open Enrollment

HICAP is now offering an online form for help with any Open Enrollment issues. Please use this form to contact us for help with your decisions for next year, including finding the best drug plan, comparing available Medicare Advantage plans, requesting documents in the mail, or any other questions related to Open Enrollment. With this form you will have the option to receive counseling over the phone, or by email exchange. You can still use our phone number (above) if you prefer not to use this form. (But – please DO NOT use both!)
