In-House vs Outsourced Medical Billing: Cost Comparison

Comparing in-house vs outsourced medical billing takes more than checking a salary against a service fee. Your practice also needs to consider software, supervision, backup coverage, and the work your staff will retain.

An internal team may understand your practice well and manage billing effectively. An outside partner may provide capacity for tasks that are falling behind.

Neither arrangement guarantees lower costs or better collections.

Start with your current workload and performance. Then compare written proposals against the same responsibilities.

What Are You Comparing?

Before reviewing costs, list the tasks your practice needs.

These may include:

• Eligibility and benefits verification
• Prior authorization tracking
• Charge entry
• Coding review
• Claim submission
• Rejection correction
• Payment posting
• Denial management
• Accounts receivable follow-up
• Patient billing
• Reporting

Next, identify who handles each task today and which duties an outside partner would take over.

For example, one proposal may include patient calls and appeals. Another may cover claim submission and payment posting only.

A price comparison will be misleading if the services differ.

Use our Medical Billing Services Checklist to review the scope.

Calculate Your In-House Billing Costs

Internal billing costs often sit across several expense categories. Bring them together before comparing options.

Staffing and Supervision

Include the costs your practice pays for billing staff:

• Salaries or hourly wages
• Employer payroll taxes
• Benefits
• Overtime
• Training
• Temporary coverage

Also account for management time. A practice owner or manager may spend hours answering questions, reviewing reports, and handling unresolved accounts.

If an employee splits time between billing and other duties, estimate the share used for billing. Avoid counting the employee’s full cost unless their whole role belongs in the comparison.

Software and Tools

Review the systems your team uses, such as:

• Practice management software
• Clearinghouse services
• Verification tools
• Reporting tools
• Secure communication systems

Then ask which costs would remain if you outsourced.

For example, your practice may still need its current software even when an outside team handles claims. That expense would not disappear simply because responsibilities change.

Recruitment and Training

Hiring a replacement can involve recruitment fees, interviews, training, and supervision.

Use your practice’s actual records where available. If you estimate a cost, label the assumption clearly.

Also consider who completes billing tasks while a position remains open.

Backup Coverage

Review what happens when a staff member takes leave or becomes unavailable.

Who submits claims? Who posts payments? Who follows up on urgent payer requests?

A capable internal team may already have backup coverage. If yours does not, include the cost of creating it.

Review Outsourced Billing Fees

An outside company may charge a percentage of collections, a fixed fee, or another agreed amount.

Ask for a written explanation of the calculation.

For percentage pricing, clarify:

• Which collections count toward the fee
• Whether patient payments are included
• How refunds affect the calculation
• Whether older accounts carry a separate charge
• Whether a minimum monthly fee applies

Also check for setup, software, reporting, and termination fees.

The quoted percentage alone does not show your total cost.

Include the Work Your Practice Retains

Your team will still have responsibilities under an outsourced arrangement.

These may include:

• Completing clinical records
• Providing missing information
• Answering clinical questions
• Approving refunds and write-offs
• Reviewing reports
• Managing the billing relationship

Some proposals may also leave patient calls, coding review, or authorization work with your practice.

Therefore, add retained staff time and continuing software expenses to the service fee.

In-House vs Outsourced Medical Billing: An Illustrative Example

Suppose a fictional practice collects $2 million annually.

The following figures are assumptions for explaining the calculation. They are not market averages, a vendor quote, or a prediction of savings.

In this example, the recurring difference is $15,000 annually.

However, assume the transition also costs $8,000 in the first year. The first-year outsourced total would then be $143,000, leaving a difference of $7,000.

The comparison assumes both options cover the same work and produce the same collection results.

Change the fee, staffing needs, retained duties, or transition costs, and the answer changes. Replace every assumption with your practice’s records and a written proposal.

Compare Performance Alongside Cost

A lower expense does not necessarily mean a better arrangement.

Review how each option will manage:

• Claims awaiting submission
• Rejections awaiting correction
• Unposted payments
• Denials needing action
• Unpaid accounts
• Patient billing questions

For example, an inexpensive service may leave denial follow-up with staff who already lack time for it.

Likewise, an internal team may cost more but provide strong performance and dependable coverage.

Use consistent measures when comparing results. Define claim denial rate, reporting periods, and account aging before drawing conclusions.

Also separate delayed payment from money the practice cannot recover. A denied claim may later receive payment after correction or appeal.

Check Continuity and Accountability

Both internal and outside teams need a backup plan.

Ask who handles work during leave, turnover, or a sudden rise in volume. For an outside partner, request details rather than assuming backup coverage comes with the contract.

Your practice should also know:

• Who manages daily work
• Who handles unresolved questions
• Where staff record activity
• How often you review progress
• Which actions require approval
• How you report a service problem

Clear responsibilities make it easier to assess the arrangement and resolve issues.

When Keeping Billing In-House May Fit

An internal team may suit your practice when it has:

• Reliable performance
• Enough capacity for the workload
• Strong supervision
• Documented processes
• Effective backup coverage
• Tools and reporting that meet your needs

Unusual workflows may also need close internal coordination.

However, practice size alone does not decide the answer. A large organization can have billing gaps, while a small team can manage its work well.

Review the actual process before replacing it.

When Outside Support May Fit

Outside support may help when your practice has a specific capacity gap.

Examples include:

• Older unpaid accounts need follow-up
• Payment posting has fallen behind
• Staff lack time to resolve rejections
• A vacancy has interrupted billing work
• The owner handles routine payer calls after hours

You do not have to outsource the entire cycle.

A combined approach may let your internal biller retain oversight while a partner handles selected tasks.

Plan the Transition Before Making a Change

Include transition work in your in-house vs outsourced medical billing comparison.

Agree on:

• Who works claims submitted before the start date
• Who handles older accounts
• Who posts payments during the transition
• Who answers patient billing questions
• How both teams avoid duplicate work
• What happens to open accounts when the agreement ends

Also clarify system access, account ownership, and data handling.

A lower recurring fee may offer little value if the transition leaves important work without an owner.

Make the Decision Using Your Practice Data

Gather a consistent period of records, such as the previous 12 months.

Review:

• Billing expenses
• Staff time and backup needs
• Claim volume
• Denial patterns
• Unpaid balances by age
• Payment-posting backlogs
• Time spent correcting errors

Then compare options using the same scope and assumptions.

The best choice is the arrangement your practice can afford, monitor, and maintain. It should also give unresolved work a clear next step.
