NHI Independent Enrollment Mandarin Question

Anybody know how to say, “I want to apply for independent enrollment in the National Health Insurance program,” in Mandarin? Soon I will be quitting my regular gig and will be paying for NHI on my own. I can normally do fine in all situations with Mandarin, but I don’t want go into the NHI administrative offices and stumble through this like if I’m at a 生活百貨 looking for some teflon tape. :laughing:
