The problem isn't the industry, it's the framing. Nobody follows a collection agency, but people absolutely follow content that helps them navigate confusing medical bills. If you reposition from "we collect medical debt" to "we help people understand healthcare costs," the content opportunities open up pretty quickly.
Break down a real medical bill line by line and explain what each charge actually means. Walk through what happens when you can't pay. Explain the difference between being sent to collections vs. setting up a payment plan. Answer the questions people are too embarrassed to ask anywhere else.
The accounts that work in difficult industries tend to lean into transparency rather than trying to make the industry look fun. Showing what actually happens behind the scenes, even the uncomfortable parts, is what separates a real follow from a pity follow. Educational content around healthcare finance has a genuine audience because almost everyone has been confused by a medical bill at some point.
