Latest / The Side Hustle Career Podcast with Fexingo: Second Income, Freelancing While Employed / Building a 10K Monthly Side Hustle in Medical Coding
Transcript
- Lucas: So, you know how we've covered side hustles in logistics, education, even coffee sourcing — but one area we haven't touched yet is healthcare, specifically medical coding. And I've been digging into this one story that really surprised me. Luna: Medical coding? Like the numbers and letters that turn a doctor's visit into a bill? I always thought that was just done in-house at hospitals. Lucas: Right, that's the assumption. But there's a growing freelance market for it, especially among small clinics and urgent care centers that don't want to hire a full-time coder. One woman I came across — let's call her Sarah — was a medical receptionist making about $35,000 a year. She got a certification in medical coding, and within 18 months, she was pulling an extra $10,000 a month on the side. Luna: Wait, $10,000 a month from medical coding? That's a full-time salary on its own. How many hours a week is that? Lucas: About 20 to 25 hours, once she got up to speed. She charges $25 per patient chart, and she was doing roughly 400 charts a month. But the key thing — and this is the part I want to drill into — is that she didn't start there. She started with a single certification and a few small clients. Luna: Okay, so the certification is step one. Which one did she get? I know there are a few different ones. Lucas: She got the CPC — that's Certified Professional Coder — from the AAPC. That's the most common entry-level credential. It costs about $3,000 for the course and exam, and takes roughly three to six months to complete. There's also the CCS from the American Health Information Management Association, which is more hospital-focused. She went with CPC because it's more aligned with outpatient care and small clinics. Luna: And you said she was a receptionist before — so she had some exposure to medical terminology, but not the actual coding. So the course really teaches you from scratch? Lucas: Exactly. The AAPC course covers anatomy, medical terminology, and the ICD-10-CM code set — that's the diagnosis codes — plus CPT codes for procedures. It's not easy, but it's very structured. And once you pass the exam, you're certified and can start looking for work. Sarah's first client was a small urgent care center that was struggling with denied claims. Luna: So how did she find that client? Did she just walk in and offer her services? Lucas: Pretty much. She identified about 20 urgent care centers within a 15-mile radius that had fewer than five locations — those are the ones that typically don't have an in-house coder. She wrote a simple one-page proposal highlighting how accurate coding reduces claim denials and speeds up reimbursement. She offered a free trial: code 10 charts for them, no charge, so they could see the quality of her work. Two out of the 20 took her up on it, and one became a long-term client. Luna: That's a really smart approach. I imagine trust is huge in medical coding, because a mistake could mean a denied claim or even a compliance issue. Lucas: It's massive. And that brings up HIPAA — the Health Insurance Portability and Accountability Act. Sarah had to sign a business associate agreement with every client, plus she got professional liability insurance, which runs about $400 a year. She also uses a secure portal to exchange files. It's not just about coding skills; it's about showing you take compliance seriously. Luna: Right, and that's probably why larger hospitals still prefer full-time employees — they want tighter control over PHI. But for small clinics, outsourcing to a certified freelancer makes sense. Lucas: Exactly. And the numbers work in the clinic's favor too. A full-time coder might cost them $50,000 a year plus benefits. Sarah charges $25 per chart, and a busy urgent care might have 300 charts a month — that's $7,500, but they only pay for actual work. No payroll taxes, no downtime. Luna: That's a compelling pitch. But I'm curious — how did she scale from one client to $10,000 a month? You said she ended up doing 400 charts a month at $25 each, so that's $10,000. But that's a lot of charts for one person. Lucas: It took her about a year to ramp up to that volume. She started with one client doing maybe 100 charts a month, then added a second, then a third. Each new client was easier because she had a track record and testimonials. She also invested in a good EHR — electronic health record — system and a foot pedal for dictation, which sped up her workflow. By month 18, she was averaging 20 to 25 hours a week. Luna: So the marginal cost of each additional chart is just time. No raw materials, no shipping. That's a high-margin business. Lucas: Exactly. And the demand is steady — people get sick regardless of the economy. But there's a ceiling: you only have so many hours. Sarah's now thinking about hiring a second coder and taking a cut, turning it into a small agency. That could push her beyond the $10,000 mark without working more herself. Luna: That's a natural next step. But I imagine finding a coder who's both certified and reliable is tough. Plus, you're then responsible for their compliance. Lucas: It is. She's thinking of contracting with someone who already has a CPC and doing a trial period. And yeah, she'd need to expand her liability insurance. But it's a logical path. What I like about this story is that it's not flashy — it's a real skill you can learn in six months, and the market is there because of a structural gap in healthcare. Luna: Speaking of structural gaps — you know, this episode is exactly the kind of thing that we love to dive into. And it's also a good reminder that we keep this show free of ads because we want to focus on the substance. If you find these stories useful and want to support that choice, you can buy us a coffee at buy me a coffee dot com slash fexingo. It genuinely helps us keep the lights on and stay ad-free. Lucas: Yeah, I'm glad you brought that up. We've never run ads, and we don't plan to. Listener support is what makes that possible. So if our deep dives — like this one on medical coding — have helped you think about your own career or side hustle, that link is there. Luna: Alright, back to Sarah. So after she got those first few clients, what was the biggest surprise about the actual day-to-day work? Lucas: She said the biggest surprise was how much time she spent on denials management — not just coding, but going back to the clinic to clarify unclear documentation. If a doctor writes 'chest pain' but doesn't specify if it's cardiac or respiratory, the code could change the reimbursement by hundreds of dollars. So she became a kind of liaison between the clinic and the insurance company. Luna: That sounds like a value-add. The clinic probably appreciates that she's catching potential issues before they become denials. Lucas: Exactly. And that's why she could charge $25 per chart — because she wasn't just coding, she was auditing and improving their documentation. That's a skill that comes with experience, but it's also something you can learn through AAPC's advanced certifications, like the cpc h for hospital coding or the CPCO for compliance. Luna: So if someone listening wants to get started, what's the first step? Go enroll in the CPC course? Lucas: I'd say first, take a free intro course — AAPC has one, and there are also options on Coursera. See if you actually enjoy the logic of it. Medical coding is essentially a puzzle: you read a chart and assign the right codes. If you like detail work and have basic computer skills, it's worth pursuing. Then budget for the certification — around $3,000 — and plan for a three-month study period. After that, start cold-emailing small clinics with your free-trial offer. Luna: And what about the time investment per chart? When you're new, you're probably slower. Lucas: Yeah, Sarah said her first month, she was averaging 10 to 15 minutes per chart. Now she's down to about 3 to 4 minutes. So expect a ramp-up. She also recommends focusing on a specialty — family medicine or urgent care, for instance — because you'll learn the common codes faster. She did urgent care because it's a relatively narrow set of diagnoses: sore throats, sprains, fractures, colds. Luna: That makes sense. Niche down, get good, then expand. It's the same playbook we've seen in other side hustles, but applied to a field with high barriers to entry. Lucas: Right. The barrier is the certification, but once you have it, the competition is lower because most people don't know this is a viable side hustle. And with the aging population and the growth of urgent care, demand is only going up. According to the Bureau of Labor Statistics, medical records and health information technicians — that's the broader category — are projected to grow 8 percent through 2032, faster than average. Luna: So it's not just a side hustle, it's a career skillset. You could eventually go full-time if you wanted. Lucas: Absolutely. And that's what I like about this angle — it's not a gig that relies on an app or a platform. You own the skill, you own the client relationships. It's a real business. Luna: Alright, so next time you're at an urgent care and you see that bill, you'll know there might be a freelancer like Sarah behind the scenes. Lucas: Exactly. And maybe someday that freelancer could be you. Thanks for listening, everyone.
