This guide opens with the point where a practice outgrows partial billing help, then walks what full service outsourcing, or FSO, covers from scheduling through the final payment. It sets FSO against modular and hybrid deals, marks which revenue cycle decisions stay with you, and shows how a firm prices a whole cycle. Then it draws the scope boundary that sinks most agreements, names the service levels worth putting in writing, and answers who owns the billing software once the work moves out. It covers the runway to steady state, the monthly numbers that prove a partner is working, and what happens to the existing billing team. Last come the practice profiles that fit poorly, how to unwind a contract, and where every figure on this page comes from.
At a glance
Full service outsourcing earns its place when the gaps between part-time billing help have hardened into a standing backlog, and nobody inside the practice owns a claim from check-in to final payment. Partial help is a person. Whole-cycle help is a contract.
The tell isn't one bad month. It's a pattern. One billing specialist covers coding, appeals and credentialing at once, a denial queue has sat unopened since spring, and a single resignation stalls submissions for weeks. Practices in that position keep buying more hours, and hours aren't the shortage. What's missing is somebody accountable for the figure at the bottom of the aging report.
Two other signs matter. Your payer mix has grown past what one person tracks, with a different appeal window and portal rule for each plan. And the office has started writing off balances it could still have appealed, because working them costs more attention than anyone has left at five o'clock.
Full service outsourcing covers every step a claim takes, starting at scheduling and eligibility, running through coding and submission, and finishing at the posted payment and the patient balance that closes the account. Where a firm stops short of that, you've bought a module at a whole-cycle price.
Four blocks of work sit inside a whole-cycle agreement, and a proposal naming only two of them isn't one.
Rules for the middle two come from outside the contract. The Centers for Medicare and Medicaid Services (accessed September 2026) publishes what each claim has to satisfy in its Medicare coding and billing guidance, and a firm working around those rules is manufacturing denials rather than clearing them.
FSO differs from modular and hybrid outsourcing by how much of the cycle leaves the building, since a modular deal buys one function and a hybrid deal keeps the judgment work in-house while the high-volume queues go out. The three price differently because they sell different things.
Modular outsourcing is the narrow buy. A practice hands off coding alone, or prior authorization alone, and keeps everything either side of it. Hybrid sits in the middle and is where most mid-size groups land, with coding and payer contracting kept by named staff while eligibility checks, claim follow-up and posting move to a partner who does nothing else all day. Full service outsourcing takes the lot, including the parts you'd rather not think about, and hands back a monthly report.
Watch the drift. Hybrid deals grow into full service outsourcing one addendum at a time, and the service levels written for the first function rarely survive the fourth. Rewrite them each time the scope widens, or the newest work arrives with no measure attached to it.
Full service outsourcing moves the work and not the authority, so the practice keeps its payer contracts, its fee schedule, its write-off and refund thresholds, and the clinical documentation standing behind every code. A firm advises on all four. Signing stays with you.
Payer contracting is the clearest case. Rates, terms and participation are a business decision, and no billing partner negotiates them for you unless you've written that into scope and paid for it. Write-off authority is the one practices give away by accident, by leaving the threshold unnamed and letting the firm's habit become the policy. Name a dollar figure, then require a second signature above it.
Documentation stays clinical. A coder queries a note, the provider answers it, and nobody outside the practice changes what the record says. Refund and credit-balance decisions belong on your side too, since they carry compliance exposure that no invoice discount offsets.
A full service outsourcing firm prices a whole revenue cycle two ways, as a percentage of what it collects for you or as a quoted figure against a contracted scope, and almost nobody publishes either number. Of the twelve firms in the researched pool, exactly one publishes a whole-cycle rate.
| Pricing basis | What the fee buys | Who publishes a figure | Best fit |
|---|---|---|---|
| Percentage of collections | The firm's share of what lands in your account | Transcure, 3% to 5% of monthly collections (company-reported) | Practices handing off the whole cycle |
| Priced on request | A contracted scope, staffed and measured by the firm | AGS Health, Access Healthcare, Omega Healthcare, Sagility and Firstsource publish none | Hospitals and health systems |
| Hourly staffing, which is not full service outsourcing | People who work your queue under your direction | Honest Taskers $10.00 to $12.65 per hour; Staffingly $399 per week at 45 hours (company-reported) | Practices keeping the outcome in-house |
Percentage pricing climbs with revenue, which suits a growing practice less well than a flat number does. Honest Taskers belongs in the third row rather than the first two, because it staffs the revenue cycle by the hour and doesn't sell the whole-cycle model, which leaves the outcome and the payer strategy with your own team. That's the limit of the staffing tier, stated plainly. Practices weighing the other two tiers can start from our ranking of the healthcare RCM outsourcing companies.
A badly drawn scope boundary sinks full service outsourcing because the work nobody named still has to happen, and it lands back on the front desk weeks after everyone agreed the billing had moved out. The boundary fails quietly, which is what makes it expensive.
Seven jobs sit near the edge of a whole-cycle scope and drop out of most proposals.
Old accounts receivable is the eighth and the most argued. Claims aged before go-live are somebody's job, and a firm paid on collections works fresh claims first. Say in writing who works the pre-go-live balance, on what schedule and at what rate. A denials and appeals specialist can work that backlog.
Six service levels belong in a full service outsourcing agreement, claim submission lag, denial touch time, appeal filing, payment posting lag, the monthly reporting date and escalation response. Each needs a number, and the firm proposes its own rather than accepting a round figure you invented.
| Service level | What the clause has to name | How you check it |
|---|---|---|
| Claim submission lag | Days from encounter close to the claim going out | Pull a month of encounter and submission dates yourself |
| Denial touch time | Days from remit to the first worked action | Sample ten denials and read the activity log |
| Appeal filing | Share of appealable denials filed inside the payer window | Compare filed appeals against each payer's deadline |
| Payment posting lag | Days from remit receipt to posted payment | Reconcile deposit dates against posting dates |
| Reporting date | The calendar day each month the report lands | Note the date it arrives, three months running |
| Escalation response | Hours to a named person on a stuck claim or an audit | Test it once during onboarding |
No firm in the researched pool publishes standard service levels on its site, so there's no market figure to hold a bidder to. Get each one to state its own in the proposal, then make the stated numbers contractual. Turnaround on a stuck claim is the one to test before signing, not after. Denial handling is where the money sits, and our guide on denials and appeals specialist companies shows how firms that do only that work describe their turnaround.
Full service outsourcing runs on one of two software arrangements, your practice management system with the firm logged into it, or the firm's own platform with your data sitting inside it, and whoever signs the license owns it. That single choice decides how hard leaving will be.
Keeping your system is the safer default. Data stays where you read it, reports come out of software your staff already knows, and an exit means revoking logins rather than extracting a database. The firm's platform costs less up front, since its license is folded into the fee, and it often runs better because its own people work in it daily. Portability is the price.
Ask four things before signing. Who holds the clearinghouse contract, who owns the payer portal credentials, what format your data comes back in, and how long the firm keeps it afterward. The Department of Health and Human Services (accessed September 2026) sets what a business associate has to safeguard in its HIPAA Security Rule guidance, and a signed business associate agreement puts those duties on the firm.
The runway to steady state under full service outsourcing runs through three stages, system access and payer setup, a parallel period on live claims, then the full handoff, and no firm in the researched pool publishes how long that takes. A duration isn't available anywhere, so get a dated plan instead.
Stage one is administrative. Logins, payer roster, fee schedule, charge master, provider enrollment status and the escalation list all move across, and a gap here surfaces as a denial in week five rather than as a problem in week one. Stage two runs both operations at once on real claims. That costs money and repays it, because you watch a firm work your payers before the whole queue depends on them. Stage three is the handoff.
Ask a bidder for four things in writing. The stage list with dates, the first calendar month it will report on in full, who works claims in flight on cutover day, and what happens to the backlog sitting behind them.
Five monthly numbers prove a full service outsourcing partner is working, the clean claim rate, the denial rate, days in accounts receivable, the net collection rate, and aged receivables over ninety days as a share of the total. Read them together, because any one of them moves for reasons that have nothing to do with the firm.
Set the baseline yourself in the month before go-live, since a partner reporting against its own starting figures is grading its own homework. Denials are worth attacking upstream as well as down, and our guide on how to reduce claim denials covers the registration and eligibility causes a billing firm can't fix from its end.
The existing billing team either moves into oversight or leaves, and full service outsourcing forces that choice in the first month, because two teams working the same claims is how a transition stalls. Decide before the contract starts.
One role stays on your payroll whatever else happens. Somebody in the practice reads the monthly report, approves write-offs above the threshold, answers the firm's coding and documentation questions, and owns the relationship when a payer audit lands. Most practices hand that to the office manager and underestimate what it takes.
Knowledge is the part nobody plans for. Your biller carries payer quirks, local plan rules and fee schedule history that exists in no document, so capture it in writing before the last day. On money, compare a quote against loaded employment cost rather than base salary. The U.S. Bureau of Labor Statistics (2026) publishes that in its release "Employer Costs for Employee Compensation", which puts wages, benefits and payroll taxes in one figure.
Full service outsourcing fits poorly at four kinds of practice, one whose billing already works, one whose front-end data is a mess, one too small to interest a whole-cycle firm, and one that won't let go of payer decisions. Three of those are timing problems. The fourth is temperament.
A practice hitting its clean-claim and aging targets with current staff takes on transition risk for no clear return. One with a stale fee schedule, wrong payer records and undocumented write-off history hands a firm garbage and gets billed for cleaning it up. Solo and the smallest offices rarely reach a whole-cycle firm's minimum at all, which is why the staffing tier exists and why the broader healthcare outsourcing companies roster separates the tiers before comparing anything else.
Then there's the owner who wants a partner's throughput and none of its authority. Every write-off gets questioned, every payer call gets taken back, and the arrangement ends in renegotiation inside a year.
A practice unwinds a full service outsourcing contract by working the exit clause it signed at the start, because claims in flight, open receivables, the data and the portal logins all have to come home before the final invoice clears. An exit written after the relationship sours gets written by the firm.
Six items belong in the termination clause.
Collections arriving after termination are the fight nobody expects. A firm paid on a percentage has worked claims that pay next quarter, and it wants its share. Agree the tail period and the rate now. Pull your aged receivable report the day notice goes out, since it's the only clean record of what you handed back.
Company facts come from the outsourcing and revenue cycle pools researched on 2026-08-21, each field read from the company's own site. Published pricing is the market describing itself. Transcure's 3% to 5% of monthly collections, Staffingly's $399 per week and Honest Taskers' $10.00 to $12.65 per hour are company-reported, so confirm them in a quote. Enterprise pricing isn't publicly listed, so no figure is attached here. Transition length, denial benchmarks and service levels aren't published by any firm in the pool, so this page says what to ask instead. Coding rules reference the Centers for Medicare and Medicaid Services, safeguards the Department of Health and Human Services, and employment cost the U.S. Bureau of Labor Statistics (2026).
Once the tier and the boundary are settled, the next question is who sits on your side of the line reading the reports each month. Practices keeping an in-house owner over an outsourced cycle can compare the revenue cycle specialist companies on published rates and stated terms, which is the hiring decision that follows this one.
