Most private practices under 10 providers reach a point where billing stops being a task and starts being a problem. The physician or office manager is chasing denials, resubmitting claims, and losing track of aging accounts receivable. The practice is leaving money on the table not because the services weren’t rendered, but because the billing workflow broke down somewhere between charge capture and payment posting.
Outsourcing medical billing means handing some or all of the revenue cycle to an external company. But the decision is not as simple as “hire someone else to do it.” What you outsource, what you keep, what it costs, and how the transition works all matter.
What outsourced billing actually covers
A full-service outsourced billing arrangement typically handles:
- Charge entry and claim submission. The billing company receives encounter data from the practice, codes it (or reviews the coding), and submits claims to payers.
- Eligibility verification. Checking patient coverage before the visit so the practice knows what will be covered and what the patient owes.
- Denial management. Reviewing denied claims, identifying the reason, correcting errors, and resubmitting. This is where most in-house billing operations fall behind.
- Payment posting. Recording payments from payers and patients, reconciling against expected amounts, and flagging underpayments.
- Accounts receivable follow-up. Working unpaid claims on a regular cycle, calling payers, and escalating when needed.
- Reporting. Monthly or weekly reporting on collections, denial rates, days in AR, and other performance metrics.
Some billing companies also handle credentialing, patient statements, and prior authorizations. Others focus strictly on claim submission and AR. What is included varies by company and contract.
The practice typically still owns the patient relationship, the clinical documentation, and the EHR. The billing company works within the practice’s existing system or uses a bridge to pull encounter data.
When outsourcing makes sense
There is no universal rule, but certain patterns push practices toward outsourcing.
The practice has one or two billers who cannot keep up. If the in-house biller is constantly behind on denials, AR is aging past 90 days, and the practice does not have the volume to justify a second hire, outsourcing can close the gap without adding headcount.
The practice cannot absorb turnover. If the sole biller leaves, the practice may go weeks or months without effective billing. Outsourced billing provides continuity that does not depend on a single employee.
Denial rates are climbing and nobody has time to analyze why. A billing company that manages denial patterns across many clients can often identify and fix systemic issues faster than an in-house biller working in isolation.
The physician is spending time on billing instead of patients. In solo practices especially, the physician may be reviewing EOBs, calling payers, or managing the billing workflow. That time has a direct opportunity cost.
When in-house billing works
Outsourcing is not always the right call.
The practice has an experienced, reliable biller who delivers results. If AR is clean, denial rates are low, and the biller is not at risk of leaving, the practice may be better off keeping what works.
The practice needs tight control over patient communication. Some practices prefer that billing questions and patient statements come directly from their office, not from an external company.
The practice has complex workflows that require close coordination. Surgical practices with multi-step prior authorizations, for example, may benefit from having billing staff physically in the office who can coordinate with the clinical team in real time.
What outsourced billing costs
Most outsourced billing companies charge a percentage of collections. The industry range is roughly 4 to 10 percent of net collections, depending on specialty, claim volume, and the scope of services included.
For small practices with lower volume, the percentage tends to be higher — typically 7 to 10 percent — because the billing company’s fixed costs are spread over fewer claims. Larger practices with higher volume can often negotiate rates in the 4 to 7 percent range.
Some companies charge a flat monthly fee or a per-claim fee instead. Flat fees typically range from $1,000 to $2,500 per month for a small practice. Per-claim fees usually run $4 to $10 per claim.
For comparison, an in-house biller’s fully loaded cost — salary, benefits, software licenses, clearinghouse fees, and training — typically runs $50,000 to $80,000 per year for a solo or small group practice. Whether outsourcing saves money depends on the practice’s collection volume and the billing company’s performance.
The percentage model aligns the billing company’s incentive with the practice’s revenue. If the company collects more, it earns more. That alignment can be useful, but it also means the practice should monitor performance, not just the bill.
What to look for in a billing company
Not all billing companies are the same. The questions that matter most:
Experience with your specialty. Billing rules vary by specialty. A company that bills for orthopedic surgery may not understand the nuances of behavioral health billing, and vice versa. Ask how many clients they have in your specialty.
Experience with your EHR. The billing company needs to work within your system or have a reliable way to receive encounter data. If they have never worked with your EHR, the onboarding will be harder and errors are more likely early on.

Transparency and reporting. The billing company should provide regular, readable reports on collections, denial rates, days in AR, and claim volume. If the reporting is vague or infrequent, the practice cannot evaluate whether outsourcing is working.
Denial management process. Ask how they handle denials. A company that resubmits claims without analyzing root causes is not solving the problem. A good billing operation tracks denial patterns and works with the practice to fix upstream issues.
Contract terms. Look at the contract length, termination clause, and what happens to data if the relationship ends. Some contracts include termination fees or long notice periods. The practice should be able to leave without losing access to its own billing data.
HIPAA compliance. The billing company will handle protected health information. They should have a signed Business Associate Agreement and be able to explain their security practices.
How the transition works
Switching from in-house to outsourced billing is not instant. A typical transition takes 30 to 60 days and involves:
- System access. The billing company gets access to the EHR, practice management system, and clearinghouse.
- Data review. The company reviews current AR, open claims, denial patterns, and payer mix to understand the starting position.
- Workflow mapping. The practice and billing company agree on who handles what — charge capture, coding, prior authorizations, patient statements, and payment posting.
- Parallel period. Some practices run in-house and outsourced billing side by side for a few weeks to catch errors and ensure nothing falls through.
- Handoff. The billing company takes over and begins working the full revenue cycle.
The first 60 to 90 days after transition are the most important. The practice should monitor AR aging, denial rates, and collection velocity closely during this period.
Common mistakes
- Choosing a billing company based on price alone without evaluating performance metrics.
- Not defining the scope of services clearly in the contract, leading to gaps where nobody is handling certain tasks.
- Assuming outsourcing means the practice no longer needs to think about billing. The practice still needs to provide clean documentation, respond to coding questions, and review reports.
- Not checking references or asking for client retention rates.
- Signing a long-term contract before seeing results.
How Neobill can help
Neobill works with private practices under 10 providers, across 9 and more EHR platforms. The free audit reviews the practice’s current billing performance — denial rates, AR aging, collection trends, and payer mix — and identifies where outsourcing would make a measurable difference and where the current setup is working fine.
