Week 9: The Business Behind the Bill

This week I continued working at the office and shifted my research focus to something that has been sitting in the background of this entire project since week one. Every time I talk about administrative burden, insurance paperwork, and the cost of billing, there is an entire industry operating behind the scenes that most people never think about. This week I dove into the world of medical billing companies, what they are, how they work, how much they cost, and why their industry is growing faster than almost anything else in healthcare.

To give some context, a medical billing company is a third party business that a practice hires to handle all of its insurance claims, coding, and payment collection on their behalf. Instead of employing a full in-house billing team, practices outsource this work to specialized companies that do nothing but manage the financial side of healthcare. Dr. Levi mentioned back in Week 2 that she outsources her billing, and at the time I noted it without fully understanding the scope of what that meant. This week I finally dug into it.

The first article I looked at was a market research report from Grand View Research on the US medical billing outsourcing market. The numbers were honestly staggering. The US medical billing outsourcing market was valued at $6.95 billion in 2025 and is projected to reach $17.69 billion by 2033, growing at a rate of 12.56% per year (Grand View Research, 2025). To put that in perspective, this is one of the fastest growing sectors in the entire healthcare industry. The main drivers of this growth are the increasing complexity of insurance codes and regulations, the rising rate of claim denials, and the pressure on practices to reduce administrative burden so staff can focus on patient care (Grand View Research, 2025). The fact that an entire multi-billion dollar industry exists purely to handle the paperwork side of getting doctors paid says everything about how broken and complicated the current system is. It is not just an inconvenience. It is a structural problem that has spawned its own economy.

The second article I read was a detailed breakdown of medical billing costs from Viaante, published in 2026. This one put real numbers on what outsourcing actually costs a practice. Billing companies typically charge between 4% and 10% of a practice’s gross collections (Viaante, 2026). To make that concrete, for a practice collecting $85,000 per month, a 7% billing fee means paying $5,950 every single month just for billing services alone (Viaante, 2026). For a small independent pediatric practice like Dr. Levi’s or Dr. Abramov’s, that is a significant chunk of already thin profit margins. The article also cited data from the American Medical Association showing that physicians and staff spend an average of 14.5 hours per week on prior authorizations alone, and data from the Healthcare Financial Management Association showing that reworking a single denied claim costs between $25 and $117 (Viaante, 2026). Perhaps most telling, nearly 60% of practices with under 10 physicians are now considering outsourcing at least part of their billing operations, which shows just how widespread this problem has become (Viaante, 2026).

Putting all of this together, what becomes clear is that the billing burden is not just a cost, it is a symptom of a broken reimbursement system that has grown too complex for independent practices to manage on their own. The insurance system has become so complex that an entirely separate industry worth nearly $7 billion has emerged just to manage it. And the practices paying for that industry, particularly small independent ones serving Medicaid dependent communities, are the ones who can least afford it. When Dr. Levi said that 20% of her operational focus goes toward billing, she was not exaggerating. She was describing a reality that tens of thousands of independent practices across the country are living every single day.

Thanks for reading, see you in the next one!
