Percentage-of-collections is the default pricing model in medical billing, and it produces the question every practice owner eventually types into a search bar: what percentage is normal? The short answer is a range. The useful answer is understanding why the range exists, what a given percentage should include, and when a different pricing model serves you better. All figures below are typical published industry ranges, not quotes — your specialty, volume, and claim mix set the real number.
What is the typical percentage-of-collections fee?
Across the industry, 3–8% of monthly collections is the typical published range for full-service billing, and quotes of 4–10% are common for smaller or more complex accounts. Where you land inside that spread is driven by a few predictable factors:
- Claim volume. High-volume practices get lower percentages; the biller's cost per claim drops with scale.
- Average claim value. A practice billing large surgical claims pays a lower percentage than one billing many small visit claims — same work, bigger denominator.
- Specialty complexity. Specialties with heavy prior authorization, frequent appeals, or tricky coding sit at the higher end.
- Payer mix. Medicaid-heavy and workers'-comp-heavy books take more follow-up labor per dollar collected.
- Scope. A fee that includes credentialing, eligibility checks, and patient statements is a different product than claims-only submission.
A useful sanity check: a very low quoted percentage on a low-value claim mix often signals a submit-and-forget operation. Percentages only make sense in light of what happens after a claim denies.
What should a percentage fee include?
Before comparing numbers, compare scope. A full-service percentage fee typically covers charge entry, claim scrubbing and submission, payment posting, denial follow-up and appeals, patient statements, and monthly reporting. The carve-outs are where surprises live: some firms bill separately for appeals beyond a first resubmission, patient collections calls, credentialing, or even reporting. Others quietly exclude old accounts receivable from the work — they bill the new claims and let your backlog age. Get the inclusion list in writing, and ask specifically who works denials and how many times they will touch a claim before writing it off.
What are the alternatives to percentage pricing?
| Model | How it works | Typical shape |
|---|---|---|
| Percentage of collections | Fee scales with what you collect | 3–8% typical; 4–10% for small/complex accounts |
| Flat monthly fee | Fixed retainer regardless of collections | Priced to expected volume; predictable budgeting |
| Per-claim | Fixed price for each claim submitted | Commonly a few dollars per claim at published rates |
| Hourly / dedicated staff | You buy billers' time rather than outcomes | Common in BPO arrangements with dedicated teams |
| Hybrid | Small base fee plus a reduced percentage | Splits risk between practice and biller |
Per-claim pricing rewards volume but pays the biller the same whether the claim gets paid or denied — watch follow-up quality. Hourly and dedicated-team pricing is the model we use most at SS Support Network, and the trade-offs between percentage and time-based pricing are big enough that we wrote a separate comparison: percentage vs hourly billing.

Percentage pricing shines when your collections swing month to month — the fee flexes with revenue, and the biller only earns more when you do. It stings when collections grow: the same 6% on double the revenue is double the fee for roughly similar work. Flat fees invert that: beautiful predictability, and a bargain as you grow, but the biller's incentive to chase every last denial is structurally weaker, so oversight matters more.
Decision factors, honestly stated: choose percentage if your volume is variable, you want incentive alignment, and your average claim value is modest. Lean flat or dedicated-team if your volume is high and stable, your claims are high-value, or you want billing cost to stay level while you scale. And in every model, the contract's service levels — days to submission, denial touch counts, reporting cadence — predict your collections better than the pricing structure does.
What does a percentage fee look like in real dollars?
Percentages hide their size, so translate them. As an illustrative example — not a quote — take a practice collecting $50,000 a month, or $600,000 a year:
- At 4% of collections: $2,000 per month, $24,000 per year
- At 6% of collections: $3,000 per month, $36,000 per year
- At 8% of collections: $4,000 per month, $48,000 per year
Two lessons fall out of the arithmetic. First, a two-point difference in rate is $12,000 a year at this volume — worth an hour of negotiation and scope comparison. Second, the fee grows automatically with your collections: the same 6% costs twice as much in dollars once you double revenue, even though the biller's workload does not double in step. That growth dynamic is precisely why larger practices drift toward flat-fee or dedicated-team pricing over time, and why the right answer at $250,000 in collections is often the wrong answer at $1.5 million.
Are percentage fees allowed everywhere?
Mostly, but not universally. A small number of states restrict percentage-based billing arrangements for certain claim types or provider situations, and some government programs have their own rules about contingency-style fees. Reputable billing companies know the rules in your state and will say so plainly. It is worth one direct question — "are there any restrictions on percentage billing for my claims in my state?" — and a written answer before you sign.
What questions should you ask before signing?
- What exactly is included in the percentage — and what bills separately?
- Is the percentage charged on collections, or on charges billed? (It must be collections.)
- Who works denials, how many attempts, and within how many days?
- Will you work my existing accounts receivable backlog, and at what rate?
- What reports do I get monthly, and can I see a sample?
- What are the contract term, exit clause, and data-return terms if we part ways?
- Will you sign a Business Associate Agreement?
How do the numbers compare with keeping billing in-house?
The percentage question hides a bigger one: outsource at all, or staff it? An in-house biller costs far more than a salary once payroll taxes, benefits, software seats, clearinghouse fees, training, and coverage for vacations and turnover are loaded in. Outsourced billing teams typically cost 35–70% less than that fully-loaded in-house cost (SS Support Network operations data). If you are running that comparison, our medical billing service page shows scope, and the pricing page shows how dedicated-team pricing is structured — both give you real inputs for the math rather than a rate card in a vacuum.
Frequently asked questions
Most medical billing companies charge 3-8% of monthly collections, with 4-10% common for low-volume practices or complex specialties. The rate depends on your claim volume, average claim value, specialty complexity, and payer mix. What the fee actually covers - denial follow-up, appeals, patient statements, reporting - matters more than the headline percentage.
Percentage pricing is usually cheaper for practices with variable or lower collections, since the fee flexes with revenue and aligns the biller's pay with what you actually collect. Flat monthly fees win for high, stable volume or high-value claims, where a fixed rate stays level as collections grow. Match the model to your volume, not the reverse.
A percentage fee should always be charged on collections - money actually received - never on charges billed. Billing on charges pays the company whether or not claims get paid, which removes their incentive to work denials. Before signing, confirm in writing that the percentage applies to collected revenue only.
A full-service percentage fee typically includes charge entry, claim scrubbing and submission, payment posting, denial follow-up and appeals, patient statements, and monthly reporting. Common carve-outs to check are credentialing, patient collection calls, and old accounts-receivable backlog. Get the inclusion list in writing and ask who works denials, and how many times, before write-off.
Outsourced billing usually costs less than an in-house biller once you load in payroll taxes, benefits, software seats, clearinghouse fees, training, and turnover coverage. Outsourced teams typically run 35-70% below that fully-loaded in-house cost (SS Support Network operations data). The gap widens for small practices, where one biller's idle hours are pure overhead.
