Choosing a medical billing company is not simply a software decision or a comparison of percentage fees. You are deciding who will manage claim submission, payment posting, denial follow-up, patient billing, and the day-to-day work that keeps cash moving through your practice. The right partner should fit your specialty, work inside your existing systems, show you what is happening in the revenue cycle, and make a transition without disrupting collections.
This buyer’s guide explains how to compare outsourced medical billing with an in-house team, how common pricing models work, what to ask prospective vendors, and how to switch medical billing companies with less risk. Use it to create a short list, evaluate proposals on equal terms, and identify the questions that matter before you sign an agreement.
Short answer: what should you look for?
- Experience with your specialty, payer mix, and care settings
- A clearly defined scope that covers more than claim submission
- Transparent pricing, contract terms, and exit requirements
- Access to reports for denials, A/R aging, collections, and payer performance
- A named contact and a documented escalation process
- A realistic implementation plan for data, payer access, and open A/R
Outsourced vs. In-House Medical Billing
An in-house team gives a practice direct day-to-day control, but it also makes the practice responsible for recruiting, training, coverage, technology, and ongoing payer-rule changes. Outsourcing shifts much of that operational burden to a vendor, but it requires clear accountability, reporting, and communication. Neither model is automatically right for every practice.
| Decision area | In-house billing | Outsourced billing company |
|---|---|---|
| Staffing | The practice hires, trains, manages, and covers absences. | The vendor manages staffing and continuity. |
| Cost structure | Mostly fixed payroll, benefits, software, and training costs. | Often variable pricing tied to collections, claims, or an agreed monthly scope. |
| Specialty expertise | Depends on the experience and stability of the people hired. | Can provide a broader team, but specialty experience must be verified. |
| Technology | The practice owns configuration, updates, interfaces, and support. | A strong vendor can work inside the practice’s current EHR and billing systems. |
| Scalability | Growth usually requires recruiting and training additional staff. | Capacity can expand through the vendor’s team if service levels are defined. |
| Visibility | Direct access is high, but reporting may depend on internal discipline. | Visibility depends on the quality and frequency of the vendor’s reporting. |
| Management burden | Billing operations remain the practice’s responsibility. | The vendor manages the workflow, while the practice manages the relationship and clinical inputs. |
Outsourcing is often worth evaluating when turnover, delayed claims, inconsistent denial follow-up, or lack of management reporting is putting pressure on the practice. An in-house model may still make sense when the practice has stable leadership, strong specialty expertise, documented workflows, and enough volume to support appropriate coverage.
How Medical Billing Companies Charge
Medical billing proposals are difficult to compare when the fee looks simple but the scope is not. A lower percentage can cost more if important work is excluded, while a higher fee can be reasonable when it includes coding review, denial appeals, patient statements, reporting, and old A/R follow-up. Compare the full operating model rather than one number.
Percentage of collections
The billing company is paid a percentage of the revenue it collects. This aligns cost with cash flow and is common for full-service billing. Confirm which collections are included in the calculation, whether patient payments are counted, and whether old A/R has a different rate.
Per-claim pricing
The practice pays a set amount for each claim submitted. This can be predictable when volume is stable, but it may not include payment posting, denial work, appeals, or patient balances. Ask what happens after the initial claim is sent.
Flat monthly fee
A fixed monthly amount can simplify budgeting. The proposal should define volume assumptions, included services, and what triggers an additional fee. Flat pricing is only useful when both sides have the same definition of the monthly workload.
Hybrid or project pricing
Some relationships combine a base fee with a performance component, or price implementation, credentialing, coding audits, or old A/R as separate projects. Those fees are not automatically a problem, but they should be visible before the agreement is signed.
For a deeper breakdown, review what medical billing services cost and request a proposal based on your actual specialty, payer mix, claim volume, and current A/R.
What a Medical Billing Proposal Should Include
Ask every company to price the same scope. A useful proposal should state whether the following work is included, optional, or excluded:
- Eligibility and benefits verification
- Charge entry and coding review
- Claim scrubbing and electronic submission
- Clearinghouse rejections and payer edits
- Electronic remittance and payment posting
- Denial analysis, corrected claims, and appeals
- Underpayment identification and follow-up
- A/R follow-up by aging bucket and payer
- Patient statements, payment support, and collections workflow
- Monthly reporting and account-review meetings
- Credentialing or payer-enrollment coordination
- Implementation, data conversion, and open-A/R work
If a proposal uses broad phrases such as “full-service billing,” ask the company to attach a responsibility matrix. It should show what the practice does, what the vendor does, and which handoffs have deadlines.
How to Compare Medical Billing Companies
1. Start with specialty fit
Ask for the company’s experience with your claim types, procedure mix, place-of-service requirements, modifiers, prior authorizations, and most common denials. A cardiology group, behavioral health practice, orthopedic office, and small primary-care clinic do not have identical revenue-cycle needs.
2. Define ownership across the revenue cycle
Clarify who verifies benefits, reviews documentation, enters charges, works rejections, posts payments, manages denials, contacts patients, and follows aging A/R. Problems usually appear at the handoffs that neither side clearly owns.
3. Evaluate reporting before you sign
Request sample reports and meeting agendas. At minimum, the practice should be able to review charges, payments, adjustments, denial categories, A/R aging, payer performance, and work completed. Reporting should lead to action rather than simply produce a monthly spreadsheet.
4. Understand who will manage the account
Ask whether the practice will have a named account representative, how quickly questions are answered, who handles escalations, and how coverage works when a team member is unavailable. Confirm whether work is performed domestically or offshore and how access to protected health information is controlled.
5. Test the implementation plan
A credible implementation plan addresses EHR access, payer portals, clearinghouse enrollment, electronic remittance, bank and lockbox workflows, provider files, fee schedules, open claims, and reporting. It should also state what the practice must provide and when.
6. Read the contract as an operating document
Review the initial term, renewal language, termination notice, implementation fees, minimum charges, excluded services, data ownership, access after termination, and responsibility for claims still in process. The exit plan matters even when everyone expects a long relationship.
Medical Billing Company Switching Checklist
- Document the current baseline. Save recent reports for charges, payments, denials, A/R aging, payer mix, and key performance measures.
- Review the existing agreement. Confirm notice periods, data-return requirements, open-A/R responsibility, and any transition fees.
- Choose a cutover date. Decide which service dates the new company will bill and who owns older claims.
- Create an access inventory. List the EHR, practice-management system, clearinghouse, payer portals, ERA, EFT, lockbox, and reporting tools.
- Validate provider and payer files. Confirm NPIs, tax IDs, locations, enrollments, fee schedules, and electronic-payment settings.
- Transfer open work. Account for unsubmitted charges, rejected claims, pending appeals, payer requests, patient balances, and aging A/R.
- Run parallel checks. During the first weeks, compare charge volume, submitted claims, rejections, payments, and missing remittances.
- Set an escalation rhythm. Schedule frequent implementation meetings until access, claim flow, and reporting are stable.
- Protect data access. Remove old credentials only after required files are returned and responsibility for open claims is confirmed.
- Review the first 30, 60, and 90 days. Measure workflow completion and claim movement before drawing conclusions from cash alone.

Frequently Asked Questions
How long does it take to switch medical billing companies?
The timeline depends on system access, clearinghouse and payer setup, provider files, and the condition of open A/R. A vendor should provide a written implementation plan before the cutover date.
Do we need to replace our EHR to outsource billing?
Not necessarily. Many billing companies work inside the practice’s existing EHR and practice-management system. Confirm compatibility and access requirements during the proposal process.
Should the lowest percentage win?
No. Compare the included scope, additional fees, reporting, denial work, old-A/R responsibility, and staffing model. A lower rate can be more expensive when essential work is excluded.
What information should we share to receive an accurate proposal?
Be prepared to discuss specialty, providers, locations, payer mix, monthly charges and collections, claim volume, current A/R, systems, and the services your staff will continue to perform.
How can we evaluate our current billing before switching?
Start with recent A/R aging, denial, payment, and adjustment reports. A structured review can identify whether the main issue is staffing, workflow, coding, payer follow-up, or reporting.
