Outsource medical billing for less than an in-house team

By Sam, CPC · Reviewed by Harpreet, CPC · Updated Nov 7, 2026

PhysiAssist Health takes over coding, claim submission, payment posting, denials and AR follow-up for US practices, for 2.8% to 5% of net collections, with no setup fees and no minimums. Below you can compare that with what billing in-house really costs, see the risks worth checking before you sign, and how practices switch in 2 to 4 weeks.

The basics

What is medical billing outsourcing?

Medical billing outsourcing means a practice hands the work of turning visits into payments to an outside billing company, also called a third-party medical biller, instead of employing its own billing staff. The outsourced team codes or reviews the charges, submits clean claims, posts payments, works denials and follows up on unpaid claims, usually inside the practice's own EHR and practice management system. Most outsourced medical billing services charge a percentage of what they collect, so the cost rises and falls with revenue instead of being a fixed payroll line.

STEP 1

Charges captured

Your providers document and close the visit in your EHR, as they do today.

STEP 2

Coded and submitted

Certified coders assign CPT, ICD-10 and modifiers; claims are scrubbed and sent through the clearinghouse.

STEP 3

Paid and posted

Payer payments land in your bank account (a few payers still mail checks to your practice); we post ERAs and EOBs and reconcile them to deposits.

STEP 4

Denials and AR worked

Every denial is fixed at its cause and every open claim is followed up until it is paid or closed.

What you hand over

What our outsourced billing services cover, and what stays with you

The rate pays for the work from coding to collection. Front-desk work and other services are optional and quoted separately, so you only pay for what you hand over. Full list on the pricing page →

Included in 2.8% to 5% of net collections
  • Medical coding by certified coders, or review of your providers' codes
  • Charge entry, claim scrubbing and submission, clearinghouse rejections fixed
  • Payment posting from ERAs and EOBs, reconciled to deposits
  • Denial management: root cause, corrections and appeals
  • AR follow-up on every open claim, old AR included
Optional, quoted separately
What usually stays in your office
  • Scheduling and checking patients in
  • Clinical documentation and closing notes on time
  • Collecting copays at the visit
  • Decisions on write-offs, payment plans and fee schedules
  • Owning your EHR, your data and your payer contracts

Calculator

In-house vs outsourced medical billing cost calculator

Move the sliders to match your practice. Wages default to the US median for medical records specialists, and benefits use the national private-industry ratio, so the in-house figure is a fair floor, not a worst case.

Yearly cost of billing in-house

$116,196

10.8% of collections

Yearly cost of outsourcing

$48,600

Outsourcing costs less by$67,596 a year
Wages / benefits (43% of wages)$76,710 / $32,886
Break-even monthly collections$215,177

Below the break-even, outsourcing at this rate costs less than this staff level. Above it, the deciding factors are results: denial rate, days in AR and what is collected.

An estimate to compare options, not a quote. It leaves out revenue gained or lost through denials and slow follow-up, which often matters more than the fee.

Worked example

The cost of outsourcing medical billing for a 3-provider practice

A family medicine practice with three providers collects $90,000 a month, or $1.08 million a year. One full-time biller handles claims and posting, and a part-time colleague spends half her week on denials and AR calls.

Cost line (per year)Billing in-houseOutsourced to PhysiAssist
Billing wages1.5 FTE × $51,140 = $76,710$0
Benefits and payroll costs42.9% of wages = $32,886$0
Clearinghouse and billing tools$300 × 12 = $3,600Included
Training, coding updates, cover for leave$3,000Included
Billing feeNone4.5% × $1,080,000 = $48,600
Total$116,196 (10.8% of collections)$48,600 (4.5% of collections)
  • Where 42.9% comes from: in June 2026, US private employers paid $14.07 an hour in benefits for every $32.82 in wages and salaries (BLS Employer Costs for Employee Compensation), which is 42.9% on top of wages.
  • Why 4.5%: a practice under $200,000 a month usually lands between 4% and 5%; the exact rate is set in writing after the assessment.
  • What the table leaves out: collections. If an outsourced team lowers the denial rate or recovers old AR, the gain is usually larger than the fee difference. If it performs worse than your staff, no fee saving makes up for it, which is why the questions further down matter.
  • Break-even: at this staffing, in-house billing costs $9,683 a month, so outsourcing at 4.5% costs less until collections pass about $215,000 a month. Larger practices need more billing staff too, so run your own numbers in the calculator.

Benefits

Benefits of outsourcing medical billing

The reasons practices outsource, and what each one looks like in numbers you can check.

1. Lower, variable cost

The fee replaces wages, benefits, billing tools and training, and it falls when collections fall. In the worked example above, that is 4.5% of collections instead of 10.8%.

2. No single point of failure

Claims keep going out through resignations, vacations and sick leave, because a team, not one biller, owns your account.

3. Fewer denials

41% of providers report denial rates of 10% or more (Experian Health, State of Claims 2025). A team that tracks every denial by payer and cause can stop the repeats instead of reworking them.

4. Faster cash

An orthopedic group in California cut days in AR from 59 to 35 within 45 days of handing over its revenue cycle. Case study →

5. Old AR recovered

A psychiatry clinic in Massachusetts recovered $1M of backlog in 75 days, and days in AR fell from over 90 to under 40. Case study →

6. Time back for the practice

Managers stop chasing claims and covering the billing desk, and providers get questions only when a chart truly needs them.

Pros and cons

Risks of outsourcing medical billing, and how to protect yourself

Outsourcing goes wrong in predictable ways. Each risk below has a safeguard you can put in the contract.

RiskWhat goes wrongSafeguard to ask for
Losing controlYou stop knowing which claims are unpaid and whyWork done in your EHR and practice management system, with claim-level status you can see any time
Hidden feesSetup, per-statement, appeal or software charges appear after signingA written list of what the percentage covers and what is extra. PhysiAssist charges no setup fees and has no minimums
Payment handlingPayer money flows through the vendorPayments go to your bank account, or by check to your practice, never to the vendor. Medicare only pays a billing agent whose pay is not tied to amounts billed or collected (42 CFR 424.73(b)), so percentage-priced vendors should never receive your payments
Upcoding exposureCoders rewarded for higher-paying codesCoders paid for accuracy, not dollars, and regular audits. The OIG has warned that percentage arrangements can raise the risk of upcoding (Compliance Program Guidance for Third-Party Medical Billing Companies, 1998)
Data securityPatient data copied to vendor laptops or unknown systemsA business associate agreement, a named security standard such as ISO 27001, and no local downloads of PHI
Lock-inHard to leave, or your data is held backYour data stays in your systems, with exit terms and data return written into the agreement
Transition gapOld claims go unworked while the new team startsOld AR worked in parallel, and every claim filed on time (Medicare's limit is 12 months from the date of service, 42 CFR 424.44)
When billing in-house still makes sense
  • You have an experienced, stable team and your denial rate, days in AR and net collection rate are already where they should be.
  • Your collections are high enough that fixed staff cost less than a percentage, and you can absorb turnover.
  • Only one stage is struggling. You can outsource just that piece: coding, denials and AR recovery or prior authorization.

Onshore, offshore or blended

Offshore medical billing: what changes and what to check

Many outsourced billing companies, including PhysiAssist, use teams in more than one country. What protects you is not where people sit but how they reach your data and who is accountable for the work.

US-only team

Same time zone and the highest labor cost. Usually priced at the top of the market, which suits practices with contracts that require onshore access to patient data.

Offshore team

Lower cost and work that continues overnight. The risks are data handling, communication and accountability, so check how PHI is accessed and who you call when something breaks.

How PhysiAssist works

US headquarters in Sheridan, Wyoming, with team offices in Mohali, India and Abbotsford, Canada. Everyone works inside your systems or our Microsoft Azure environment, no PHI is downloaded to a local device, and we are ISO 27001 certified with a BAA for every client. Trust center →

Choosing a partner

How to choose a medical billing outsourcing company: 10 questions

Ask every company on your shortlist the same questions, and get the answers in writing.

  1. What exactly is the percentage taken from? Net collections, gross charges and "all payments" give very different bills. Ask for a sample invoice.
  2. What is included, and what costs extra? Coding, appeals, patient statements, credentialing and reporting are common add-ons.
  3. Are there setup fees, minimums or a long term? And what are the exit terms and how is your data returned?
  4. Do payer payments go straight to our account? They should, for the reason in 42 CFR 424.73(b) above.
  5. Who will work our account? Names, certifications such as CPC, where they are based, and one person who answers for results.
  6. Will you work in our EHR and practice management system? Moving to the vendor's system makes leaving harder.
  7. Which KPIs do you report, and how often? At least clean claim rate, denial rate, days in AR and net collection rate, against your starting point.
  8. How do you handle our old AR during the switch? It should be worked in parallel, not left with the old team.
  9. How do you protect patient data? A BAA, a named security standard and where PHI is accessed from.
  10. Do you bill our specialty today? Ask for a reference or a case study in your field.

Switching

How to outsource your medical billing without a gap in cash

Whether you are moving from an in-house team or another billing company, claims keep going out and old AR keeps getting worked.

  1. Days 1–5

    Agreement and access

    Business associate agreement, access to your EHR and practice management system, provider and payer list, fee schedules.

  2. Days 6–14

    Set up

    Payer-specific scrubber rules, coding guidelines for your specialty, enrollment checks, and a list of claims nearing filing limits.

  3. Weeks 2–4

    Claims go out

    New claims are coded and submitted by our team, with daily check-ins until the queue is steady.

  4. In parallel

    Old AR worked down

    Open balances are worked by age, oldest and largest first, so nothing passes its filing limit during the move.

Your billing staff do not have to leave. Many practices move them to front-desk, eligibility or patient-balance work, which outsourcing does not replace.

Medical billing outsourcing questions

How much does it cost to outsource medical billing?

Most outsourced medical billing services charge a percentage of collections; some charge per claim, a flat monthly fee or for dedicated staff. PhysiAssist charges 2.8% to 5% of net collections, with no setup fees and no minimums. Compare that with your full in-house cost, including benefits and billing tools, using the calculator on this page.

Is outsourcing medical billing worth it for a small practice?

Usually, because a small practice pays for a full biller's wages and benefits but has no backup when that person leaves. In the worked example, a three-provider practice collecting $90,000 a month pays about $116,000 a year to bill in-house and $48,600 to outsource at 4.5%.

What are the pros and cons of outsourcing medical billing?

The pros are lower and variable cost, no single point of failure, specialty coding knowledge, fewer repeat denials and faster cash. The cons are less day-to-day control, possible hidden fees, data-security exposure and the effort of switching. Each con has a contract safeguard, listed in the risks table above.

What is third-party medical billing?

It is another name for outsourced medical billing: an outside company, the third party, prepares and submits claims, posts payments and follows up with payers on the practice's behalf. The practice remains the billing provider, and payer payments should still go to the practice's own account.

Will we lose control of our billing if we outsource?

Not if the work happens in your own EHR and practice management system and you can see each claim's status. Write-off rules, payment plans and fee schedules remain your decisions; the outsourced team carries them out and reports on them.

Is offshore medical billing HIPAA compliant?

It can be. HIPAA does not ban offshore work, but the vendor must sign a business associate agreement and protect patient data wherever its team sits. Ask how data is accessed, whether anything is downloaded, and which security standard the company is certified to. Check your payer contracts too, since some restrict offshore access.

What happens to our current billing staff?

Many practices keep them and move them to front-desk, eligibility, copay collection or patient-balance work, which outsourcing does not replace. Others reduce billing hours over time as staff leave.

How do we move to an outsourced billing company without losing cash?

Keep the old AR being worked while new claims start with the new team, and list every claim close to its filing limit before the switch. With PhysiAssist, claims start going out 2 to 4 weeks after the agreement is signed.

Do you charge setup fees or require a minimum?

No. There are no setup fees and no minimums. You pay a percentage of net collections between 2.8% and 5%, confirmed in writing before you sign.

Which practices and systems do you work with?

Specialty practices, ASCs and groups across oncology, behavioral health, cardiology, gastroenterology, pain management, physical therapy, DME and more, working in systems such as Epic, athenahealth, eClinicalWorks, NextGen, AdvancedMD and OncoEMR.
