Your Medical Practice Billed $3 Million—So Why Did You Collect So Much Less?

Imagine your medical practice billed $3 million this year. Your waiting room is full, your providers are booked, and your billing reports show millions of dollars in charges. Then you look at the bank account and ask a frustrating question: “If we billed $3 million, where is the money?”

Imagine this.

You own a medical practice.

Maybe you're a primary-care physician, specialist, surgeon, pediatrician, cardiologist, dermatologist, or another independent physician.

You have multiple employees. Your providers see patients every day. The schedule is full.

Your billing system reports $3,000,000 in charges.

That sounds like a $3 million business.

Then your CPA asks: “How much did you actually collect?”

The answer is $1,850,000.

You immediately ask: “What happened to the other $1.15 million?”

That question takes us into one of the most important financial concepts for medical-practice owners:

What you bill is not necessarily what you are going to collect.

And even what you collect is not necessarily what you are going to keep.

Charges Are Not Revenue in Your Bank Account

Imagine your practice bills $500 for a service, but the insurance company's contracted allowed amount is $280.

The payer pays part. The patient owes part. The remaining contractual amount may be adjusted.

Your billing system can show $500 of gross charges, but economically the practice was never necessarily going to collect the full $500.

A physician should not judge the size or profitability of the practice by gross charges alone.

Imagine Billing $3 Million and Collecting $1.85 Million

At first glance, you may think: “We're losing more than $1 million.”

Not necessarily. Some of the difference may be expected contractual adjustments.

But some may also represent denied claims, unworked claims, coding issues, credentialing problems, patient balances, slow collections, claims that were never submitted correctly, old accounts receivable, or write-offs.

The valuable question is: How much of the difference is normal—and how much represents money the practice should have collected?

Payer Mix Can Completely Change the Economics

Imagine two medical practices each see 1,000 patients per month with similar services.

Practice A has a payer mix dominated by higher-reimbursing commercial insurance. Practice B has a different mix of government programs, lower-paying contracts, self-pay patients, and other payers.

The two practices can have completely different financial results.

Patient volume alone does not tell you how profitable the practice is. You need to understand who is paying you.

Not Every Insurance Contract Pays the Same

Imagine you perform the same service for three patients.

Payer A allows $200. Payer B allows $150. Payer C allows $110.

Same provider. Same office. Same staff. Same procedure. Different economics.

Multiply those differences across thousands of patient encounters and payer contracts can have an enormous impact on profitability.

Your Highest-Volume Payer May Not Be Your Best Payer

Suppose one insurance company represents 35% of your patients.

But reimbursement is weak, claims are frequently denied, payment takes longer, administrative burden is higher, and prior authorizations consume staff time.

Now compare that with a payer representing only 15% of patients but paying faster and at stronger rates.

Volume does not automatically equal profitability.

Accounts Receivable Aging Tells a Story

Imagine your medical practice has $800,000 of accounts receivable.

Break it down: $300,000 at 0–30 days, $180,000 at 31–60, $120,000 at 61–90, $80,000 at 91–120, and $120,000 over 120 days.

That last number should get your attention.

The older a receivable becomes, the more important it is to understand why it has not been collected.

“The Billing Company Handles That” Is Not Enough

Many physicians outsource billing, and that can work extremely well.

But outsourcing billing does not mean the owner should stop monitoring collections.

You should still know how much was billed, collected, adjusted, denied, sitting in A/R, aging, and being written off.

A billing company performs a function. The physician still owns the financial result.

Denials Are Not Just a Billing Problem

Imagine your practice has $100,000 of denied claims sitting unresolved.

That is a business problem.

Why were the claims denied? Coding? Medical necessity? Authorization? Eligibility? Documentation? Credentialing? Timely filing? Incorrect patient information?

The reason determines whether the money can be recovered and whether the process can be improved.

A Small Denial Percentage Can Become a Large Dollar Amount

Imagine annual collections are $3 million.

A few percentage points of preventable lost reimbursement can represent tens of thousands—or potentially much more—over the course of a year.

Small operational problems become large financial problems when multiplied across thousands of claims.

Credentialing Problems Can Stop Revenue

Imagine you hire a new physician and the doctor starts seeing patients, but credentialing with certain payers is incomplete.

Claims may be delayed, denied, or handled differently depending on the circumstances.

The physician is working, payroll is being paid, and staff is supporting the provider, but collections are not arriving as expected.

Provider onboarding is also a financial process.

Your Provider's Salary Is Not Their Total Cost

Imagine you hire a physician for $250,000 per year.

Add employer payroll taxes, benefits, malpractice insurance, retirement contributions, CME, licensing, credentialing, support staff, medical assistants, office space, technology, and billing costs.

The provider may need to generate substantially more than $250,000 of collections before the practice earns a meaningful return.

How Much Does Each Provider Actually Contribute?

Suppose your practice has three physicians and two nurse practitioners with total collections of $4 million.

Ask how much is attributable to each provider, each provider's compensation, support staff requirements, supplies, office space, equipment, and A/R.

This does not mean medicine should be reduced to a spreadsheet. It means the owner should understand the economics of the practice.

A Busy Provider Can Still Be Unprofitable

Imagine a provider sees 30 patients per day.

Everyone thinks: “They're incredibly productive.”

Maybe. But reimbursement per encounter may be weak, documentation problems may create denials, overtime may be required to support the schedule, supply costs may be unusually high, or collections may lag.

Patient volume is only one part of provider productivity.

Staffing Can Quietly Consume Your Margin

Medical practices require medical assistants, nurses, front-desk employees, billing staff, practice managers, schedulers, referral coordinators, prior-authorization staff, and other administrative employees.

Imagine collections increase 8% but payroll increases 18%.

The practice grew. But did it become more profitable? Maybe not.

Prior Authorization Has a Cost

A staff member spends hours calling insurers, submitting documentation, following up, appealing, and resubmitting.

The practice may never see a P&L line called Prior Authorization Expense.

But payroll is being consumed by the process.

Administrative complexity has a real financial cost.

No-Shows Matter in Medicine Too

Imagine a physician has 20 appointments scheduled today and four patients do not show.

The physician and staff are there. Rent and malpractice insurance are being paid. The office is open.

But those appointment slots generated no patient revenue.

Multiply that across providers and months and no-shows can become a significant financial issue.

Your Schedule Is an Economic Asset

A physician has only so many available appointment hours.

Once an unused 10:00 a.m. appointment passes, you cannot sell that same time tomorrow.

Scheduling, reminders, waitlists, and cancellation management therefore have financial value.

Medical Supplies Can Change Profitability by Service Line

Some practices use injectables, implants, specialty medications, procedure supplies, diagnostic materials, and disposable equipment.

Imagine a procedure generates $1,000 of collections but associated supplies cost $400.

That procedure does not have the same economics as another $1,000 service with $50 of supplies.

Revenue should be considered alongside direct costs.

High-Cost Drugs Require Special Attention

Certain practices purchase expensive medications or injectables before reimbursement is received.

Imagine the practice spends $100,000 on medication inventory. The drug is administered, the claim is submitted, and payment comes weeks later.

Now the practice has significant cash tied up between purchasing the medication and collecting reimbursement.

If claims are denied or payment is delayed, the cash-flow effect can become substantial.

Cash Flow Can Be a Problem Even When the Practice Is Profitable

Your income statement shows $600,000 of profit, but the bank account does not feel like it.

Cash may be tied up in accounts receivable, medication inventory, equipment, loan principal, owner distributions, tax payments, or practice expansion.

Profit and cash flow answer different questions. A physician-owner should understand both.

Equipment Decisions Should Be Financial Decisions Too

Imagine you are considering new imaging equipment, ultrasound, diagnostic or procedure equipment, a new EHR system, or office expansion.

Model the purchase price, financing, maintenance, staffing, expected reimbursement, patient volume, useful life, downtime, and tax treatment.

A large equipment purchase should make sense before considering the deduction.

Don't Buy Equipment Just Because December Is Coming

Buying a $300,000 machine you do not need simply to create a deduction is not automatically good tax planning.

You still spent or financed $300,000.

First determine whether the equipment makes economic and clinical sense. Then determine the appropriate tax treatment.

Malpractice Insurance Is Part of Provider Economics

For some specialties, malpractice insurance can be a major expense.

If premiums increase significantly, the cost of operating the practice changes.

That should be considered when reviewing provider profitability, service-line profitability, compensation, budgeting, and cash flow.

Rent and Occupancy Costs Matter

Imagine you operate a beautiful medical office with rent of $25,000 per month—$300,000 per year.

Could the practice grow into the space? Is part unused? Could another provider use it? Is the office generating enough collections to support the occupancy cost?

A prestigious office is still an overhead expense.

Multiple Locations Need Separate Reporting

Imagine your medical group has locations in Laredo, San Antonio, and McAllen with total collections of $8 million.

Which location is profitable?

One may generate the most revenue, another better margins, and another may be losing money.

If all three are combined into one P&L, the strongest office can hide problems at the weakest.

Profitability by Location Can Change Expansion Decisions

Suppose Location A produces $4 million but requires expensive staffing and rent. Location B produces $2.5 million with significantly better margins.

Which model should you replicate?

Revenue alone cannot answer that. Location-level financial statements can.

Physician Compensation Needs to Match the Entity Structure

Depending on how the practice is organized and taxed, payments to physician-owners can represent wages, distributions, guaranteed payments, or other forms of compensation.

Do not simply transfer money from the practice to the owner and call everything Owner Draw.

The accounting should reflect what actually happened.

S Corporation Physicians Need to Think About Reasonable Compensation

Imagine your medical practice is taxed as an S corporation. The physician-owner provides most clinical services. The practice generates $900,000 of profit, but the owner takes $50,000 of W-2 wages and distributes the rest.

That should raise a reasonable-compensation question.

The goal is not to pay yourself the smallest salary possible. Compensation should be supportable under applicable tax rules and facts.

Owner Distributions Can Create Their Own Cash Problem

Imagine the practice has a strong quarter and you distribute $150,000, then another $100,000.

Then payroll hits, quarterly taxes are due, malpractice renews, equipment needs repair, and A/R slows.

Now the practice needs a line of credit.

Owner distributions should be planned alongside working capital.

Tax Planning Should Happen Before the Return

Imagine your practice has its best year ever and you find out in March that the owner owes $250,000 in taxes.

The money was already distributed and spent.

Your CPA should be reviewing projected profitability during the year so estimated taxes, distributions, equipment decisions, retirement planning, and other strategies can be evaluated before year-end.

Retirement Plans Can Be Powerful for Medical Practices

A profitable physician practice may have opportunities to use qualified retirement plans for owner retirement savings, employee benefits, tax planning, and employee retention.

The correct structure depends on employees, compensation, ages, ownership, contribution goals, and cash flow.

The plan should be modeled for your actual practice.

What Should a Physician-Owner Review Every Month?

You should understand charges, contractual adjustments, collections, collection trends, accounts receivable, A/R aging, denials, collections by payer, payer mix, collections by provider, payroll, provider compensation, medical supplies, drug or inventory costs where applicable, rent, billing costs, malpractice insurance, marketing, cash, debt, owner distributions, tax reserves, operating profit, and for multi-location practices, profitability by location.

Those numbers give you a much clearer picture than: “We billed $3 million.”

Imagine Two Medical Practices Billing the Same Amount

Both bill $3 million.

Practice One understands payer mix, tracks collections, monitors denials, reviews A/R aging, knows provider productivity, controls payroll, tracks supplies, projects taxes, and maintains working capital.

Practice Two looks at gross charges, checks the bank account, and assumes the billing company is handling everything else.

Same charges. Completely different financial management.

Growth Can Hide a Revenue-Cycle Problem

Imagine your practice grows from two providers to four to eight.

Gross charges increase dramatically, but A/R grows faster, denials increase, credentialing falls behind, payroll explodes, administrative staff increases, and collections per provider fall.

The practice became bigger. But did it become better?

Growth should ultimately create stronger economics—not simply more claims.

How LUNA CPA Helps Medical Practices Understand the Numbers

At LUNA CPA, we help physician and medical-practice owners understand the financial side of the business without expecting them to become accountants.

We can help connect information from your billing and practice-management systems with your actual accounting records.

Depending on the practice's needs, our work can include monthly accounting, financial statement preparation, P&L and balance-sheet reporting, cash-flow analysis, payroll accounting, provider financial analysis, location-level reporting, accounts receivable trend analysis, payer and collection trend review using available practice data, expense and overhead analysis, equipment and fixed-asset accounting, depreciation planning, debt accounting, owner compensation and distribution planning, tax projections, estimated-tax planning, business tax-return preparation, QuickBooks setup and cleanup, financial reporting for banks and lenders, and ongoing CPA advisory.

The goal is not to replace your billing company or practice manager.

It is to connect the operational information they provide with the financial statements so ownership can understand what the practice billed, what it collected, what it cost to operate, where the cash went, and ultimately what the practice actually made.
