The Hidden Costs of In-House Medical Billing
For a medical practice, keeping its billing processes in-house seems to be one of the most logical and cost-effective options. However, you have to consider certain aspects, as your team has to handle claims, follow up with insurance companies, and manage payments.
Going by this logic, you might think that the only expense that you have to deal with is your team’s salary. But have you considered the cost of training new staff, medical billing software licensing fees, claim rework, and the time spent managing the entire process?
These expenses can easily add up faster than you expect. For instance, billing staff turnover, administrative overhead, delayed collections, and ongoing technology costs can be the hidden costs of in-house medical billing. And since many of these expenses are spread across different budgets, you can easily overlook the final cost of your entire billing operations.
This is the reason why full service medical billing companies are gaining traction with many healthcare practices. But that is the topic for another blog. For now, let’s see how much in-house medical billing costs a practice.
On that note, let’s break down the costs worth paying attention to and explore when outsourcing medical billing might make financial sense.
So, without further ado, let’s get started!
Direct Costs of In-House Medical Billing
When calculating the cost of in-house medical billing, salaries are usually the first expense that comes to mind. But running a billing department involves several other costs besides salaries, and that needs to be considered.
On that note, here are a few things that you need to consider:
Employee Salaries, Benefits, and Training
- Salaries and benefits: This includes wages, payroll taxes, health insurance, retirement contributions, and paid leave.
- Training and turnover: Onboarding new employees, updating billing knowledge, and replacing staff adds to operational expenses.
Medical Billing Software and IT Support
- Software licensing fees: Billing platform, claim-scrubbing tools, and reporting software may require separate subscriptions.
- Clearinghouse charges: Electronic claim submission fees vary depending on the vendor and claim volume.
- Hardware and IT support: Computers, maintenance, software updates, and technical support contribute to the overall cost.
Office Space and Administrative Overhead
- Workspace and utilities: Rent, electricity, internet access, and office equipment contribute to the cost of supporting billing staff.
- Administrative expenses: Management time, office supplies, and shared resources add to the cost of running the department.
In the table below, you will get a brief idea of the estimated direct costs:
| Expense | Estimated cost |
| Employee wages | 37,000–81,150/year per employee (broad occupational proxy) |
| Clearinghouse fees | 30–120/month for selected plans |
| Software, IT, and office overhead | Varies by practice |
| Benefits and training | Varies by staffing and policies |
*Estimates are based on references, not a complete budget. Actual costs depend on various factors like staffing, claim volume, and existing resources.
Hidden Operational Costs of Running an In-House Billing Department
Apart from direct expenses, there are operational costs that can affect how efficiently your billing department runs. These expenses are often harder to track because they show up as lost time, workflow delays, and additional work for your team.
Here are some of the hidden costs of running an in-house medical billing department that you should look out for:
- Recruitment and training: When a billing employee leaves, you need to spend time and money on recruiting their replacement, onboarding them, and training them on your billing processes.
- Productivity disruptions: Staff absences or vacancies can delay claim submissions, payment posting, and follow-ups with insurance companies. The remaining team may have to take extra work to keep things moving.
- Dependency on a single biller: If one employee handles most of your billing aspects, then their departure can leave a gap in process knowledge. So, finding someone who understands your existing workflows can take time.
- Management and supervision: Your practice manager or administrative team also needs to spend time monitoring your team’s performance, resolving billing issues, and keep the workflow on track. And this takes time away from other responsibilities.
These operational challenges can increase the hidden costs of in-house medical billing, even when your direct expenses remain unchanged. The impact becomes more noticeable when your practice depends on a small billing team or struggles to maintain consistent staffing.
Revenue Leakage and Other Potential Financial Losses
Even if your billing team is handling claims regularly, small gaps in the process can affect how much revenue your practice collects. These issues may not always show up as a direct expense, but they are one of the biggest causes of lost revenue, delayed payment, and additional administrative costs.
Here are some of the common revenue leakages that you need to keep an eye on:
- Missed underpayments and unresolved denials: If your team doesn’t identify payer underpayments or follow up on denied claims, your practice may collect less than it’s entitled to. Moreover, correcting and resubmitting those claims also takes time.
- Delayed submissions and follow-ups: When claims aren’t submitted promptly, or unpaid balances aren’t followed up on, payments can take longer to arrive and put pressure on your practice’s cash flow.
- Missed filing and appeal deadlines: Payers have specific deadlines for claim submissions and appeals. Missing them can make claims harder to recover and may result in lost reimbursements, depending on the payer’s rules and available exceptions.
- Additional administrative work: Billing inefficiencies often mean repeated calls to payers, manual corrections, and extra claim reviews. This takes staff time that could be spent on other billing tasks.
The financial impact depends on how often these issues occur and whether your team can resolve them. That is why looking at denial trends, accounts receivable, timely claim filing performance, and underpayment recovery can help you understand where your in-house billing process may be falling short.
How to Calculate the Total Cost of In-House Medical Billing
By now, you can see that the cost of in-house billing beyond salaries and software fees, right? However, the question still remains, ‘How do you calculate what your billing department actually costs your practice?’
Well, the easiest way is to add your direct expenses to the additional operational costs associated with running the department. Let’s try to understand this with a three-provider practice.
Let’s say a three-provider practice has the following monthly expenses. These figures are just for example and may not meet the industry benchmarks.
| Expense | Monthly cost |
| Two billing employees, including benefits | $9,000 |
| Software and clearinghouse fees | $400 |
| Hardware and IT support | $200 |
| Allocated office overhead | $600 |
| Training and turnover allowance | $300 |
| Claim rework expenses | $500 |
| Total monthly cost | $11,000 |
| Total annual cost | $132,000 |
In this example, let’s assume that the practice collects $2.4 million annually.
132,000/2,400,000 * 100 = 5.5%
This means that the practice spends 5.5% of its annual collections on billing operations under these assumptions.
When calculating your own costs, use actual payroll and benefits data, software invoices, and reasonable estimates for training and rework. Avoid counting any expenses twice, especially when benefits are already included in employee costs or software fees cover multiple services.
