In-House Billing
vs XMB — True Cost Calculator
In-house medical billing costs far more than the salary line on your P&L. Calculate your true fully-loaded billing cost — salaries, benefits, software, training, overhead, and turnover — and compare it against XMB’s performance-based fee of 3–4% of collections to see your potential annual savings.

The True Cost of In-House Medical Billing — What Shows Up on the P&L and What Doesn’t
Most practices dramatically underestimate their in-house billing cost because they look at salary alone — not the full employment infrastructure that makes that salary functional.
The salary line on a payroll report is the most visible part of a biller’s true cost — and typically the smallest portion of the real number. A medical biller earning $45,000 per year costs the practice $58,000–$65,000 once benefits, payroll taxes, and mandatory employer contributions are added. Layering in the less-visible costs — billing software licenses, continuing education, office space, equipment, management oversight, and the recurring cost of turnover — pushes a single biller’s true annual cost to $70,000–$100,000+.
Beyond the dollar cost, in-house billing carries operational risks that do not appear anywhere on a P&L: coverage gaps when the biller is sick, on vacation, or resigns; coding quality that depends on a single person’s training and attention; denial follow-up that gets deprioritized during busy periods; and no systematic process for tracking the 50–60% of denials that typically go unworked. These operational risks translate directly into the 13–18% revenue leakage that the average practice experiences — leakage that a performance-based billing service has a financial incentive to eliminate.

In-House vs XMB — Frequently Asked Questions
How much does in-house medical billing cost per year?
The true annual cost of a single in-house billing FTE is $64,000–$107,600 — significantly above the salary line that appears on the P&L. A biller earning $45,000 costs $58,500 before adding software ($3,000–$12,000/year), training ($1,500–$4,000), office overhead ($4,000–$10,000), and turnover ($3,000–$8,000 per hire at 30–50% annual turnover rates in billing roles). For a practice with two billing staff, the fully-loaded annual cost commonly exceeds $130,000–$200,000. Source: MGMA staffing benchmarks.
How does XMB's pricing compare to in-house billing costs?
XMB charges 3–4% of net monthly collections with no setup fees, no software costs, no employee overhead, and no contract required. For a practice collecting $120,000/month, XMB’s annual fee is $43,200–$57,600 — compared to $130,000+ for two in-house billers fully loaded. Beyond the direct cost savings, most practices also recover additional revenue as XMB’s billing expertise pushes the net collection ratio from the industry average of 82–87% toward XMB’s 94–97% target — often generating revenue that exceeds the service fee in the first year alone. See our full Medical Billing Services page.
What is included in XMB's billing fee?
XMB’s fee includes the complete revenue cycle management function: insurance eligibility verification, prior authorization management, AAPC-certified medical coding, charge capture, pre-submission claim scrubbing, electronic claim submission, payment posting, denial management and appeals, aged AR follow-up, patient billing, and monthly KPI performance reports. There are no additional software licenses, no training costs, no HR overhead, and no coverage gap during staff transitions. The entire billing function — performed by certified specialists — for one performance-based fee.
What happens to billing quality when you switch from in-house to XMB?
Most practices experience measurable billing quality improvement within the first 30–90 days of switching to XMB. Denial rates drop below 5% (vs. the 11.8% 2026 industry average) as upstream prevention protocols address eligibility, PA, and coding errors. Days in AR fall toward the <35-day benchmark as the systematic follow-up workflow replaces inconsistent in-house AR management. The 50–60% of denied claims that typically go unworked at in-house operations receive a defined action within 48 hours. Annual CPT and ICD-10 updates are implemented January 1 and October 1 without disruption. AAPC-certified specialty coders eliminate the coding-based denials common when generalist billers handle coding as a secondary function. See our Revenue Cycle Management page for the full KPI framework.
