Small practices get sold billing solutions designed for large groups. A percentage-based billing company charging 7% makes sense at $500,000/month in collections. At $50,000/month, you’re paying $3,500/month for a service that provides less accountability than a dedicated person working your account for $1,120/month.
The right billing model for a small practice depends on your collections volume, your specialty, and how much visibility you want into what’s actually happening with your revenue. This guide covers all three.
What “Small Practice” Billing Actually Looks Like
A small practice — solo physician, 2-3 provider group, single-specialty clinic — typically has one billing function that handles everything: charge entry, claims submission, eligibility verification, AR management, and denial follow-up. When that function works, it’s invisible. When it doesn’t, the physician finds out weeks later from an aging AR report they didn’t know to look at.
The most common billing problems in small practices aren’t complex. They’re systematic — a denial code that repeats every billing cycle because nobody fixed the root cause, a prior auth that expired and nobody caught it, a clean claim rate sitting at 87% when 96% is achievable with the right specialist. These aren’t hard problems. They’re accountability problems.
The Three Billing Models for Small Practices — With Honest Math
Model 1: In-House Biller
One person, full-time, doing your billing. Direct accountability, visible daily activity, institutional knowledge that builds over time.
Cost: $60,740–$90,260/year fully loaded (salary + taxes + benefits + recruiting + onboarding)
When it makes sense: When you need someone physically present for patient-facing billing conversations, or when you have a long-tenured biller whose specialty knowledge is irreplaceable.
The problem: Turnover. When they leave — and 11–40% of billing staff turn over annually — you absorb the full recruiting and productivity cost again. The smaller the practice, the more disruptive a single departure is.
Model 2: Full-Service Billing Company (Percentage-Based)
You hand billing to a company that handles everything. They charge 4–10% of net collections.
| Monthly Collections | Cost at 5% | Cost at 7% | Cost at 10% |
|---|---|---|---|
| $30,000/month | $1,500 | $2,100 | $3,000 |
| $60,000/month | $3,000 | $4,200 | $6,000 |
| $100,000/month | $5,000 | $7,000 | $10,000 |
| $150,000/month | $7,500 | $10,500 | $15,000 |
When it makes sense: When you want complete hands-off billing and you’re collecting enough that the percentage isn’t painful. Generally makes more sense above $200,000/month in collections.
The problem: Accountability distance. Your claims are one of hundreds. Nobody is exclusively responsible for your AR. Poor performance compounds over months before you notice.
Model 3: Dedicated Billing Staff (Hourly)
One dedicated biller assigned exclusively to your account. Works inside your EHR daily. Backed by a free RCM manager. $7/hr — $1,120/month full-time.
| Monthly Collections | Full-Service (7%) | Dedicated Staff ($7/hr) | Annual Saving |
|---|---|---|---|
| $30,000/month | $2,100/month | $1,120/month | $11,760/year |
| $60,000/month | $4,200/month | $1,120/month | $37,440/year |
| $100,000/month | $7,000/month | $1,120/month | $70,560/year |
| $150,000/month | $10,500/month | $2,240/month (2 billers) | $99,120/year |
When it makes sense: At almost every collections volume for a small practice. The dedicated model is cheaper than percentage-based outsourcing at any volume above $16,000/month, and provides more direct accountability than either alternative.
What Small Practices Get Wrong About Billing
Measuring collections instead of clean claim rate. Collections go up and down with patient volume. Clean claim rate is the number that tells you whether your billing is working — what percentage of submitted claims pay on first submission without rejection or denial. A clean claim rate below 94% means systematic errors that are costing you money every billing cycle.
Not knowing their denial rate by payer. Your overall denial rate might look acceptable. But if United Healthcare is denying 22% of your claims while Blue Cross is denying 4%, that’s a United-specific problem — likely a modifier, a prior auth issue, or a credentialing gap — that won’t fix itself. The practice that tracks denial rate by payer fixes it. The one that only looks at totals doesn’t.
Treating the biller as a cost center instead of a revenue function. The right biller pays for themselves many times over. A dedicated specialist who improves your clean claim rate from 88% to 96% on $80,000/month in claims recovers $6,400/month in claims that now pay first-pass instead of requiring rework or write-off. That’s $76,800/year — from one performance improvement.
The 5 Questions Every Small Practice Should Ask Their Billing Setup
Ask these monthly. If you can’t answer them, you don’t have visibility into whether your billing is working.
1. What is our clean claim rate this month? Should be 95%+. Under 90% means systematic problems.
2. What are our top three denial codes this month — same as last month? If the same codes repeat, the root cause hasn’t been fixed.
3. What percentage of our AR is over 90 days? Should be under 10%. Above 20% means AR isn’t being actively worked.
4. What is our net collection rate? Should be 95%+ of net collectible charges. Below 90% means money is being left on the table.
5. What happened to the claims we submitted 30 days ago? If you don’t know, you don’t have the reporting you need.
The 4-Week Free Pilot for Small Practices
The concern small practices have about switching billing setups is disruption. You’ve got one billing function. If it goes wrong during the transition, you feel it immediately.
The Dr. Billerz pilot is designed to eliminate that risk entirely. Your dedicated biller starts by reviewing your existing AR before touching any new claims — understanding your payer mix, your denial patterns, your EHR workflows. New claims only go through the biller after you’ve confirmed the setup is right. The first 4 weeks are free, so you’re not paying for a transition that hasn’t proven itself yet.
Frequently Asked Questions
What is the best medical billing service for a solo practice?
For a solo practice, the dedicated billing staff model consistently wins on cost and accountability. At $1,120/month for a full-time dedicated biller — versus $2,100–$3,000/month for a percentage-based company at 7–10% of $30,000/month collections — the economics are clear. The 4-week free pilot means you see results before committing.
How much should a small practice pay for medical billing?
A reasonable benchmark: billing costs should represent 3–7% of net collections. A full-service billing company at 7% is at the high end. A dedicated biller at $1,120/month on $60,000/month collections represents 1.9% — well under benchmark. In-house billing at $75,000/year fully loaded on $60,000/month ($720,000/year) collections represents 10.4% — above benchmark.
Can a small practice afford to outsource medical billing?
At $7/hr with a 4-week free pilot, the question reverses: can a small practice afford not to? A dedicated biller who improves clean claim rate by 8 percentage points on $50,000/month recovers $4,000/month in first-pass payments — $48,000/year — against a $1,120/month cost.
