Outsourcing, explained
Outsourced medical billing: what it is, how it works and when not to do it
Outsourced medical billing means a billing company works your claims under a business associate agreement instead of an employee on your payroll.
Remitwright assigns your practice a dedicated biller (or a dedicated team for a larger group) who works inside the practice management system you already use. Outsourcing fits when billing depends on one person or denials go unworked; it does not fit when your in-house biller already keeps days in A/R low.

Definition
What is outsourced medical billing?
Outsourced medical billing is the work of getting claims paid, done by a company outside your practice rather than by someone on your payroll. The work itself does not change: charges are reconciled to the schedule, claims are scrubbed and sent, remittances are posted, denials are appealed and the aging is chased. What changes is who employs the person doing it and what the agreement between you says.
Two things separate it from a software purchase. First, a person owns the queues, not a dashboard. Second, that person works under a business associate agreement, which is the contract HIPAA requires before anyone outside your workforce touches protected health information. A third-party biller, an outsourced medical billing company and a medical billing outsourcing service are the same arrangement under different names.
Day to day
How does outsourced medical billing work day to day?
Day to day, an outsourced biller signs in to your practice management system, EHR and clearinghouse as a user you created, works the queues in the order the deadlines demand, and leaves every action logged under their own name in your system. Rejections from the clearinghouse are fixed before the next batch goes out. Remittances are posted and read against your fee schedule. Denials get a cause, an owner and a date.
At Remitwright you get a dedicated biller (or a dedicated team for a larger group) with a named cover, and you hear from them directly rather than through a ticket queue. Once a week you receive a one-page report; once a month the account lead sends a written review, with a call when you want one. The five stages from first message to first report, and every line of the report, are published so you can hold us to them.
The decision
Should we outsource medical billing?
Outsource when the work has outgrown the people doing it. Keep it in-house when your biller is good and the problem is upstream. These are the signs that separate the two.
- One biller, no cover. When the person who knows the payers is out, the queue stops. Filing limits do not.
- Denials logged, not worked. The practice management system lists them; nobody has the hours to appeal them inside the window, so they become write-offs with a reason code.
- The over-90 bucket has grown for two quarters. Aging drifts when follow-up is the job that gets done last. Two quarters is a trend, not a bad month.
- Billing is one of several jobs for one person. The biller is also the receptionist, the scheduler and the referral coordinator, and billing is what gets dropped when the phone rings.
- The problem is upstream. If eligibility is not checked at scheduling or notes do not support the codes, outsourcing moves the denials to a new desk without stopping them. Fix the front end first.
- Most practices keep most of it in-house, and that is fine. In an MGMA Stat poll of 352 practice leaders on November 19, 2024, 36 percent said they would outsource or automate part of revenue cycle management in 2025, 50 percent said no and 14 percent were unsure; the areas named most were collections, billing and medical coding. Outsourcing is a tool for a specific problem, not a stage every practice passes through.
The work
What does an outsourced medical billing company do that billing software does not?
- Works the 277CA rejections as they come back from the clearinghouse, so a claim is never sitting in a queue nobody opens.
- Reads the 835, posts it, and checks the allowed amount against your fee schedule rather than accepting the contractual adjustment the payer proposes.
- Takes each denial to its cause inside the payer's appeal window, then sends the cause to whoever can stop it recurring: the front desk, the clinician or the enrollment file.
- Works the aging report by payer and bucket, oldest first, and logs every call and portal check so the next person can see what was done.
- Submits secondary claims once the primary has posted, with the COB and crossover rules each payer applies.
- Writes the weekly report from your own system's data, with the formula behind each line, and answers for it by name.
The whole list is full-service medical billing. Each line is also a service of its own, so a practice can hand over one stage and keep the rest.
Worked example: the internal medicine practice that outsourced denials first
An internal medicine practice with three physicians has an in-house biller who is good at charge entry and submission and has no time left for the denial queue, which has grown to several hundred items. Rather than replace her, the practice hands denial management alone to a dedicated biller. The first month of worked denials shows two patterns: a Medicaid MCO is denying for coverage terminated because eligibility is checked at check-in rather than when the visit is booked, and one commercial payer is denying 99214 with 36415 for a missing modifier. The intake template and the charge rule are changed, the appealable denials go back inside the window, and the weekly report carries one line for denials by cause. The in-house biller keeps her job and her queue gets shorter. Whether follow-up moves too is the practice's decision at the quarterly review, not a condition of starting.
What goes wrong
What goes wrong with outsourcing, and what should the agreement say?
The complaints practices bring to a second billing company are consistent: they lost sight of their own claims, the fee grew lines that were not in the quote, nobody could say who was working the account, and patients received statements the practice had not seen. Each one traces to a term that was never written down.
Require the following before you sign
- The biller works in your systems under logins you create, so nothing is hidden and nothing has to be returned.
- A report arrives on a fixed day with its definitions attached.
- Cover is a named person, not a department.
- The business associate agreement is signed before anyone has access.
- Patient statements and calls follow a policy you set, in your practice's name.
- Exit terms say what happens to claims in flight, how notice works and when access ends.
A company that resists any of these is telling you something.
Cost
How much does outsourced medical billing cost?
Billing companies charge in one of three ways: a percentage of collections, a flat monthly fee per dedicated biller, or a fee per claim. Each rewards something different, and the pricing page explains how a quote is built. Remitwright publishes no rate; a written quote follows the review.
The other side of the ledger is public. The Bureau of Labor Statistics puts the May 2025 median wage for medical records specialists at $51,140 a year, or $24.59 an hour, and its June 2026 employer cost release puts benefits at 30.0 percent of private-industry compensation. Add software seats, clearinghouse fees, recruiting and the claims that pass timely filing while a chair is empty, then divide by what the biller collects. The cost guide walks through the arithmetic and the calculator does it with your numbers.
Scope
Can we outsource only part of our billing?
Yes, and many practices start that way. Charge entry and copays stay at the desk while a dedicated biller takes the stage that leaks: denial management, A/R follow-up, old A/R recovery, credentialing, payer enrollment or prior authorization. The hand-off point is written into the scope so both sides know where a claim stops being yours and starts being ours, and the weekly report shows both halves.
When not to
Who should not outsource medical billing?
A practice whose biller is good and whose problem is somewhere else. If days in A/R are low, denials are worked inside the window and the over-90 bucket is small, a fee buys you nothing you do not have. Spend the money on the front desk's eligibility checks or on documentation instead.
A practice that would lose sight of its claims. If the company wants your data in its system, will not name your biller or will not commit to a report day, you are trading one kind of risk for another. And a practice with very low volume and no cover problem, where a part-time employee costs less than any fee and nobody is dropping anything. The in-house vs outsourced comparison sets out both cases without a thumb on the scale.
Choosing
How do you choose an outsourced medical billing company?
Ask the questions whose answers you can check.
Questions to ask
- Which of our systems will you work in, and under whose logins?
- Who is our biller, who covers them, and will we meet both before go-live?
- What does the report show and on what day?
- What is the fee base, what is passed through, and what are the exit terms?
- Which specialties and payers like ours have you worked?
The full list of questions is on the blog, and if you are leaving another company, how to switch covers notice, run-out and the parallel run.
Hand-over
How does the hand-over work, and what stays with the practice?
The hand-over runs in a fixed order:
- A written review of your aging, denials and payer mix.
- A business associate agreement.
- Users for your biller in your systems.
- A parallel run alongside your current process.
- Go-live.
- The first weekly report.
If you are leaving another company, the switching plan adds notice, run-out and who works the old A/R.
Scheduling, check-in and copays at the desk stay with you. So do clinical documentation, the coding decisions only a clinician can make, every write-off and patient-balance decision, and your systems, data and logins. We are users in them, never owners of them.
- BAA signed before any access
- A user you create and can remove
- MFA on every login that supports it
- Patient data stays in your systems
Side by side
In-house employee, hired biller or outsourced dedicated biller: how do they compare?
The three arrangements do the same claims work. They differ in who carries the employment risk, what happens on a sick day and what is written down.
| Criterion | In-house employee | Biller you hire remotely or on contract | Outsourced dedicated biller (billing company) |
|---|---|---|---|
| Who employs them | You | You, as an employee or on a 1099 | The billing company; assigned to you by name |
| Cover when they are out | Whatever you arrange | Whatever you arrange | Written into the agreement; a named cover biller who knows the account |
| Where the work happens | Your office, your systems | Their desk, your systems | Their desk, your systems |
| Software and clearinghouse | Yours | Yours | Yours; nothing migrated |
| Training and payer knowledge | Yours to build and keep | Yours to build and keep | Comes with the team; documented and left with you |
| Oversight | Direct, daily | Remote, daily | Weekly report, monthly review, direct email to the biller |
| Cost structure | Wages, payroll load, benefits, software, recruiting | Wages or an hourly rate, software, recruiting | One fee: percentage of collections, flat or per claim |
| If they leave | Vacancy until you hire again | Vacancy until you hire again | The cover biller steps in; the process stays |
| Data and logins | Yours | Yours | Yours; access removed on the date you set |

Is outsourced billing the same as buying billing software?
No. Software gives your staff a scrubber, a claim queue and reports; it does not work the denials or chase the aging. An outsourced billing company puts a person on those queues, usually inside the same software. If your staff have the hours to work the queues, software may be enough. If the queues are not being worked, software alone will not change that.
Do we keep our own software and clearinghouse if we outsource?
Yes. Your biller works as a user you create in your practice management system, EHR, clearinghouse and payer portals. Nothing is migrated and nothing is exported. If a company asks you to move systems to use its service, ask who owns the data on the day you leave.
Who owns the payer logins and the data?
You do. Users are created by you and removed by you, and the claims, remittances and reports stay in your systems from the first day to the last, so the record is already in your hands if you leave.
Can we outsource just denials or old A/R?
Yes. Denial management, A/R follow-up, old A/R recovery, credentialing and prior authorization are each scoped as a single stage. The review says whether the single stage will fix the problem or whether the cause sits upstream.
What should an outsourcing agreement include?
The scope by stage, the fee model and the base it applies to, what is passed through at cost, the report day and the definitions behind each line, the notice period, what happens to claims in flight when you leave, and a business associate agreement signed before any access.
Is outsourced medical billing HIPAA compliant?
It can be, and the rule anticipates it: the HIPAA definition of a business associate names claims processing and billing performed on a covered entity's behalf (45 CFR 160.103). Compliance rests on the agreement and the access model: a signed BAA before access, role-based users with multi-factor authentication, and no PHI copied outside your systems. The security page sets out how each is handled.
What happens if we want to bring billing back in-house later?
Your data never left your systems, so nothing is migrated back. The documented process and the payer notes are handed to your new hire, and access is removed on the date you set. Exit terms are written into the quote, so you can read them before you sign rather than when you want to leave.
