How Much Can a New Internal Medicine Practice Make?
Physicians considering opening an internal medicine practice often want to understand how much revenue and income a new practice may eventually generate. However, there is no single amount that applies to every internal medicine practice.
Revenue and profitability can vary based on patient volume, reimbursement, location, services offered, operating expenses, staffing, and how quickly the practice develops its patient base.
For physicians considering internal medicine practice financing, understanding the factors that influence practice revenue can help with financial planning and startup projections.
Here are seven factors that can affect how much a new internal medicine practice can make.
1. Patient Volume Is a Major Factor
The number of patients a practice sees is one of the most important factors affecting revenue.
A new practice may begin with a relatively small patient base and gradually increase patient volume as more patients become aware of the practice.
Patient volume can be influenced by:
- Location
- Population demographics
- Referral sources
- Marketing
- Patient reviews
- Physician reputation
- Availability of appointments
As the number of patients increases, the practice may generate more revenue, assuming the additional volume can be supported by the practice’s staffing and infrastructure.
2. Revenue Depends on the Services Provided
Internal medicine practices can provide a range of healthcare services.
The services offered can influence the amount of revenue generated per patient and the overall financial performance of the practice.
Depending on the practice, services may include:
- Routine examinations
- Chronic disease management
- Preventive care
- Diagnostic services
- Minor procedures
- Follow-up visits
Physicians should develop revenue projections based on the actual services they expect to provide rather than relying on generalized estimates.
3. Location Can Affect Practice Revenue
Where an internal medicine practice is located can have a significant impact on its growth potential.
Physicians should consider factors such as:
- Population size
- Population growth
- Age demographics
- Competition
- Insurance coverage
- Nearby employers
- Accessibility
A location with strong demand for primary care services may provide different growth opportunities than an area with a smaller potential patient population.
4. Insurance and Reimbursement Affect Revenue
The amount a practice collects for services can depend on the payer mix and reimbursement arrangements.
A practice may receive payments from different sources, including:
- Commercial insurance
- Government programs
- Patients
- Other healthcare payers
Physicians should consider expected reimbursement when developing a financial projection for a new practice.
Revenue should also be evaluated based on actual collections rather than simply the amount billed.
5. Operating Expenses Affect Profitability
Revenue is not the same as profit.
A new internal medicine practice may have significant operating expenses, including:
- Employee payroll
- Office rent
- Medical supplies
- Insurance
- Technology
- Billing expenses
- Marketing
- Utilities
- Loan payments
The practice’s profitability will depend on how much revenue remains after these and other expenses are paid.
6. New Practices May Take Time to Become Profitable
A new internal medicine practice may not reach its long-term revenue potential immediately.
During the early stages, the physician may need to spend money on staffing, office space, equipment, technology, marketing, and other expenses while the patient base is still developing.
This is one reason working capital can be an important part of a startup financial plan.
Physicians should create projections that account for the possibility of gradually increasing patient volume rather than assuming the practice will immediately operate at full capacity.
7. Growth Can Increase Practice Revenue
Once an internal medicine practice establishes a consistent patient base, the physician may have opportunities to increase revenue.
Potential growth strategies can include:
- Adding another physician
- Hiring additional clinical staff
- Expanding office hours
- Adding services
- Increasing appointment availability
- Opening another location
Growth should be planned carefully because expanding too quickly can also increase expenses and create additional financial obligations.
How Should Physicians Estimate Revenue for a New Practice?
Rather than relying on a single industry estimate, physicians should create a practice-specific financial projection.
A projection may estimate:
- Expected patient visits per day
- Average revenue per visit
- Number of operating days
- Expected collection rate
- Monthly operating expenses
- Expected staffing costs
- Debt payments
These estimates can then be adjusted to create conservative, moderate, and optimistic scenarios.
Why Conservative Projections Matter
Physicians should be careful when estimating how quickly a new practice will grow.
A conservative financial projection can provide a more realistic picture of the capital needed during the early stages of the business.
It can also help physicians determine how much working capital may be appropriate and whether additional financing may be necessary.
Can Financing Help a New Internal Medicine Practice Reach Profitability?
Depending on the physician’s qualifications, financing program, lender requirements, and intended use of funds, financing may potentially be available for eligible startup expenses.
Capital may potentially be used for expenses such as:
- Medical equipment
- Office improvements
- Technology
- Working capital
- Other qualifying business expenses
The appropriate financing structure will depend on the individual practice and its financial requirements.
Final Thought
There is no universal amount that a new internal medicine practice can be expected to make. Revenue and profitability depend on patient volume, services, location, reimbursement, operating expenses, staffing, and the pace at which the practice develops.
Physicians considering a new practice should build detailed financial projections based on realistic assumptions and account for the time it may take to establish a consistent patient base.
Understanding potential revenue and expenses before opening can help physicians determine how much capital may be required and develop a more informed plan for building a successful internal medicine practice.
