Should Your Practice Outsource Medical Billing?

By Chris Thorman

One of the many business questions physicians face is whether to outsource their medical billing to third-party medical billing services or do it in-house with medical billing software. Some physicians would assume outsourcing billing to a medical billing service makes the most sense. After all, they’re the experts with the resources to properly process your claims, right? Others might want to maintain control of collections and do it all in-house.

Hold on. Don’t make a decision before thinking it through. Both methods of revenue cycle management have benefits and drawbacks. It’s up to the individual practice to weigh the pros and cons before deciding which approach is best.

Following is an analysis of in-house billing and outsourced billing in terms of cost and qualitative factors. You’ll need to weigh the differences carefully when assessing the needs of your practice and decide if outsourcing makes sense.

Cost Analysis

For many practices, the outsourcing decision boils down to one factor: cost.

To help compare the costs of in-house billing versus outsourced billing, we’ve created a hypothetical, three-physician practice. To arrive at these numbers, we’ve used what we believe to be industry averages. Here are the characteristics of this practice: Three primary care physicians; Two medical billing specialists; 80 insurance claims filed per day (~20,000 per year); $125 billed per claim on average (~$2,500,000 per year); and, we assume that the billing service has a high collection rate on claims.

So, how much does each billing approach cost? Take a look at the annual costs:


Some background on our cost assumptions follow.

Billing staff costs. IN-HO– USE: This was calculated by adding up the median salary of two medical billing employees ($80,000), healthcare costs for two employees ($9,000), federal and state taxes for two ($12,000), and training costs to keep the employees updated on the latest industry developments ($2,000). Finally, we’ve included $15,000 in ancillary costs for statement paper, office space, office hardware and other miscellaneous costs. OUTSOURCED: We factored in five hours of time per week required to manage tasks related to billing at approximately $15 per hour. Even the best medical billing service will require follow up from a practice about particular issues. That adds up to approximately $4,000 per year in administrative costs.

Software and hardware costs. IN-HO– USE: We’ve factored in an annual cost of approximately $7,000 for practice management software (~$200 per month, per doctor) and another $500 for computer hardware costs. This does not include the upfront cost of a software system. OUTSOURCED: This reflects the computer and printer the practice would still need to interact with the billing service and print documents.

Direct claim processing costs. IN-HO– USE: Clearing house fees for a provider submitting 20,000 claims per year would be approximately $300 per month ($100 per physician), or $3,600 annually. OUTSOURCED: A medical billing service usually charges a percentage of the amount collected as their fee. The industry average varies widely by specialty. We’ve used 7% for our primary care practice.

Percentage of billing amount collected. IN-HO– USE: The percentage of revenue that a practice collects varies widely by specialty as well. Our hypothetical practice collects 60% of what it actually bills. According to industry experts, this describes an in-house billing department that is average at bill collection. OUTSOURCED: A practice can expect a 5% to 15% increase in the amount they’re able to collect by switching to a billing service. We factored in a 10% increase in the amount of money collected by a billing service as an average between the two.

Our cost comparison favors outsourcing billing, mainly based on the ability of a billing service to collect a higher percentage of the billed amount. Of course, this introduces a BIG IF. That is, outsourcing makes more sense IF the billing service improves collections significantly (i.e. on the order of 10%).

But there are other factors – beyond costs – that a provider must consider in its decision making. Let’s examine the two approaches to compare advantages and disadvantages.

In-House Process

The in-house procedure for processing insurance claims involves a number of steps that are universal to every practice. First, employees enter information into the medical billing software program from a “superbill,” which is gathered during a patient’s visit. The superbill contains particular diagnosis and treatment codes, among other patient information, which the insurance company uses to determine if the claim is legitimate.

Via the practice’s billing software, the provider then submits the claim to a medical billing clearing house, which verifies the claim and sends it to the payer. The clearing house scrubs the claim for the errors (for a fee) before passing it on to the payer. By not submitting claims directly to a payer, the provider saves time, money and lowers rejection rates. The clearing house also has the ability to format and submit claim data en masse in the various insurance company formats.

Once the claim is rejected/accepted by the payer, notification of the claim’s status is sent to the clearinghouse, which updates the provider on the status of a claim. If a claim is rejected, the provider’s staff resubmits the claim once additional information has been gathered. The practice will be charge for each claim submission, even if it’s a correction.

EHR software – especially those EHRs with a integrated practice management system – has the potential to make in-house billing easier for a practice. EHR software, when integrated with a practice management system, will populate both system’s data fields. Diagnosis codes and other information needed for billing doesn’t need to be keyed into another system. This eliminates a second round of data entry. This tighter integration may be one factor that helps keep billing in-house.

Outsourced Process

The process for outsourcing billing is more straightforward for practice staff. Superbills and other documents are scanned and electronically sent or mailed to the medical billing service. The medical billing service takes care of the data entry and claim submission on behalf of the provider. Most billing services charge a percentage of the collected claim amount. The industry average is approximately a 7% charge for processing claims through a medical billing service.

The medical billing service takes care of much of the “dirty work” associated with the billing process. It will also follow up on rejected claims, pursues delinquent accounts, and even send invoices directly to patients. The convenience factor is a major reason that providers choose to outsource.

If a practice is using EHR software, then the process is even easier. Information from a patient’s superbill is stored in the EHR and electronically transmitted to the billing service. This eliminates the need to send paper records to the billing service. And because the EHR software eliminates an extra round of data entry, accuracy is also improved.

One possible issue here is data integration between the EHR software and the billing service. The type of data being exchanged between the provider and the billing service will need to match, or else the data will need to be converted to a different format. Depending on the billing service, data conversion may be an option.

Should You Outsource Your Billing?

Besides costs, there are other factors that would spur a provider to consider outsourcing their billing.

  • Your billing process is inefficient. If you’ve been watching your collections drop while the time to collect increases, you may have issues in your billing department. Outsourcing to a third-party billing service typically decreases the number of rejected claims and decreases the time it takes to receive payment from a payer.
  • You have high staff turnover. Turnover is an issue in any industry but turnover in a provider’s billing department is especially damaging. Claim processing is the economic life blood of a practice and a new addition or replacement in the billing department will inevitably lead to slowdown in the processing of claims.
  • You’re not tech savvy. Keeping your billing in-house will require an investment in practice management software. Add in training for your staff and the significance of this investment becomes clearer. If you don’t want to deal with software upgrades and occasional technical issues, outsourcing is probably a good choice.
  • You’re a new provider. New providers have plenty to learn and worry about aside from their billing. Outsourcing their billing right off the bat can give them much needed relief from the day-to-day stress of launching a new practice, without a trial by fire in hiring, training and managing employees.
  • You have different priorities. Many doctors are not strong on the business side of running a practice. They became doctors to help patients – not worry about the administrative/clerical side of the business.  Outsourcing the billing process eliminates the hassle and frees doctors to concentrate on patients.

It’s important to note that a medical billing service isn’t a silver bullet for in-house billing issues. Billing services can vary widely in their efficiency and accuracy when processing claims. If a provider chooses a billing service that is lax and prone to errors, the headaches surrounding billing issues won’t get better – they’ll get worse.

Which Approach Should I Choose?

It’s important for a practice to factor in their individual costs and preferences when deciding whether or not to outsource their medical billing. In an apples-to-apples comparison, we found that outsourcing had the higher net income. However, cost isn’t the only issue practices should consider.  There are plenty of other factors involved in this business decision that may be as – if not more – important than costs.

    Working in the healthcare industry has been very time-consuming in many aspects, however, this article has given new dimensions to my understanding of the concepts associated with medical billing. This article will be very beneficial for my understanding.

  2. I like that this pointed out that outsourcing your medical billing is more straightforward and insures that professionals are working on it. My friend wants to start his own dental practice, so I think he’d really benefit from reading this. Is there anything else he should keep in mind about medical billing services?

  3. The cost for Outsourced billing in this model is way off. My Billing Company only charges me a percentage of what is collected not billed. This ensures they work for every dollar and if I don’t get paid then they don’t either. I know some states are a flat rate model so again this example to me is way over inflated. They put cost of hardware in the salaries section and then did it again in the software hardware column. If your a small office it is probably smarter to stay in house. But when your coding and billing needs overwhelm your staff and your AR is over the magic number than outsourcing may be the way to go.

  4. I have noticed that new medical and dental practices are especially hesitant to outsource their billing. They think that due to low volume of claims, they can handle the billing themselves. Unfortunately, it is rarely the truth.

    Great article,

    As the owner of a medical billing/practice management company in Phoenix for the past 12 years, one point that I would like to add is that many physicians choose to retain in-house billing procedures because they are afraid that outsourcing this function will result in a loss of “control” over a very important – if not the most important – aspect of their practice. However, with the technological developments we have seen during recent years, outsourcing this function to a reputable company should no longer be viewed in this way. Physician practices can maintain “live” links to their practice database as it is worked on by billing companies and data ownership should be contractually guaranteed. Many of the nightmare scenarios that can occur to a practice of the size discussed in this article can be avoided by outsourcing – e.g. the failure of a server or backup procedure and the loss of all patient demographic and financial data. This risk can obviously be mitigated by choosing a “cloud-based” practice management/EHR software, but it is just one example of what can go wrong in a busy small-to-midsize practice with a limited number of personnel.

    With ever-increasing legislative requirements being placed on medical providers – e.g. electronically secure claims and patient data transactions, electronic health records and meaningful-use compliance, in addition to what will no doubt be an increasing burden on the physician to adapt to “outcome-based” reimbursements based on ICD-10 procedure codes rather than fee-for-service payments – outsourcing the billing process should be carefully considered as a financially sound, stress-reducing move by all physician practices.

  10. This is a great article. As a certified medical biller, i often see loosing opportunities to medical billing outsourcing company in overseas. Lots of employers think that they can save money when they outsource, but in real world, it actually cost more money and they are not going to get the same qualified work as they can get from local medical biller. Thanks for sharing this!

  11. I agree with Puru, however outsourcing for a medical billing expert is hard to find. You still need to check personally the legal documents he/she holds to prove that she/he knowledgeable about it.

  12. In urgent care centers, we have seen a few (usually large, multi-site practices) that are able to handle their own billing, but in general the author’s expectation of 10% (or more) increase in collections seems to be borne out with many centers. This is especially true for urgent care, because 1) urgent care coding is so complex (involving a range of codes that cover many specialties); 2) payors include companies, work comp carriers, government payors, private payors and patients; 3) patients are more likely to stiff bills from from a doctor, with whom they do not have an ongoing relationship; 4)few software solutions are designed to handle the specific issues related to urgent care revenue cycle management. For urgent care centers that do wish to improve their billing, the Urgent Care Association of America (www.ucaoa.org) does offer classes focused on billing and coding in urgent care centers.

  13. Outsourcing to a medial billing company is the best option, if you can find a billing company that has a good structure on how to
    follow-up on medical claims. Following on up on claims is the core of medical billing.

  14. Hello Friends,

    We feel that outsourcing with one staff ( Front office work, scanning and overseeing billing company) strategy will be more suitable than doing in house. It will save time and cost.
