Business succession and M&A of internal medicine clinics represent one of the most active segments in the medical M&A market. The demand for internal medicine clinics, which form the core of community healthcare, is high. For directors and physicians considering succession, or for potential acquirers seeking new business opportunities, a deep understanding of their characteristics and evaluation points is essential. This article provides a detailed explanation from a professional perspective on the current market status of internal medicine clinic succession, the typical valuation range, the impact of specializations such as diabetes, hypertension, and home care on valuation, and even specific tax considerations unique to medical corporations.
Current Status and Characteristics of the Internal Medicine Clinic M&A Market
In Japan, internal medicine is the most common specialty for private practitioners and plays a crucial role in supporting the health of local communities. However, with the aging of clinic directors nationwide and the growing shortage of successors, business succession has become an urgent issue. Particularly, with the advancement of regional healthcare initiatives, the effective utilization of existing medical resources is being called for. In this context, M&A and business succession of internal medicine clinics are drawing attention not just as management strategies, but as vital options for the continuation of community healthcare.
The active M&A market for internal medicine clinics is driven by their stable patient base, profitability, and diverse specializations. With the increase in lifestyle-related diseases, clinics specializing in the management of chronic conditions such as diabetes, hypertension, and dyslipidemia have high, continuous demand for medical services and can expect stable revenue. Furthermore, venturing into home care can capture new demand in an increasingly aging society and enhance the clinic’s value. Succession not only prevents the loss of medical resources due to closure and contributes to the continuity of community healthcare but also offers mutual benefits: retirement planning for the seller and reduced startup risks for the buyer.
Comparison of Clinic Closure vs. Business Succession
| Item | Clinic Closure | Business Succession |
|---|---|---|
| Seller (Director) | Incurs closure costs, significant impact on patients | Receives sale proceeds, continuity for employees and patients |
| Buyer (Acquirer) | Starts from scratch with a new practice | Inherits existing patients, facilities, and staff |
| Community Healthcare | Loss of medical resources, increased burden for patients to travel | Maintenance and strengthening of healthcare provision system |
| Staff | Layoffs, search for new employment | Continued employment, stable working environment |
Evaluation Criteria and Valuation Range for Internal Medicine Clinics
The transfer price of an internal medicine clinic is generally calculated as the sum of “net asset value” and “goodwill (reputation value).” Net assets are liabilities subtracted from assets such as equipment, real estate, and cash on hand. Goodwill is an evaluation of the clinic’s future earning potential. EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) is often used to calculate goodwill, which is then multiplied by a specific factor.
The typical valuation range for internal medicine clinics with annual sales of approximately 100 million to 300 million yen often sees an EBITDA multiple of around 2 to 5 times. This results in a valuation range of roughly 30 million to 150 million yen. However, this is a general trend, and the valuation can fluctuate significantly based on individual factors such as specialization, location, patient demographics, management status, and investment in equipment. For example, clinics with a large number of stable chronic disease patients and those actively engaged in home care tend to receive higher valuations.

Strengths of Internal Medicine Clinics for High Valuation
To achieve a high valuation in the M&A market, internal medicine clinics should focus on the following elements. These factors serve as important indicators for the acquirer to assess risk and return for future stable management.
- Specialization and Sub-specialties:
- ✅ Diabetes and Endocrinology: A large number of patients require continuous management, ensuring stable medical fees. Specialized physician services offer differentiation.
- ✅ Cardiology (Hypertension, Heart Disease): Demand is high in an aging society, and specialized examination and treatment systems are valued.
- ✅ Gastroenterology (Endoscopy): Includes elements of self-pay services through examinations and procedures, often leading to higher profitability assessments.
- ✅ Home Care and Visiting Services: Demand is expanding with the promotion of integrated community care systems. The number of visits and end-of-life care achievements directly impact valuation.
- Stability of Patient Base:
- ✅ Number of Medical Claims (Recepts): Approximately 800-1,500 claims per month are considered a benchmark for stable management.
- ✅ Return Visit Rate: A high return visit rate of over 80% indicates strong patient loyalty and stable revenue.
- ✅ Proportion of Chronic Disease Patients: A higher proportion of patients requiring long-term care increases revenue stability.
- Human Resources and Organizational Structure:
- ✅ Intention of Full-time Physicians and Staff to Continue: The retention of key staff after succession leads to a smooth transition and prevents patient attrition.
- ✅ Years of Experience for Nurses and Medical Administrative Staff: Experienced staff enhance operational efficiency and the quality of patient care.
- Facilities and Systems:
- ✅ Electronic Health Records (EHR): If already implemented, it is valued for information sharing and operational efficiency.
- ✅ Diagnostic Equipment: High-function equipment such as ultrasound diagnostic devices, electrocardiographs, X-ray machines, and endoscopes expand the scope of medical practice and enhance valuation.
- Facility Standards and Licenses:
- ✅ Whether specific facility standards (e.g., primary care physician function, enhanced care function) are met and necessary licenses are properly obtained.
Key Point: Adaptability to Medical Fee Revisions
Medical fee revisions directly impact the revenue structure of medical institutions. The ability to quickly grasp revision details and flexibly adapt by acquiring appropriate facility standards or revising medical systems is a crucial evaluation factor for future stable management.
Medical Corporation Structure and Tax Considerations
When considering business succession for a medical corporation, its structure and tax implications are extremely important issues. Specifically, the procedures and tax consequences at the time of succession differ significantly between “medical corporations with equity shares” and “medical corporations without equity shares (fund contribution type).”
In the case of a medical corporation with equity shares, a change in shareholders (equity holders) involves the transfer of their shares. The proceeds from the transfer of shares are subject to taxation as capital gains. At this time, the valuation of the shares fluctuates according to the net asset value, making proper valuation essential. Furthermore, when shareholders change, procedures for amending the articles of incorporation and notifications to the prefecture are required.
On the other hand, a medical corporation without equity shares does not have the concept of equity shares but instead contributes “funds.” While there is an obligation to repay these funds, they are generally not repaid except upon the dissolution of the medical corporation. Changes in shareholders occur through the admission of new shareholders and the withdrawal of existing ones. While capital gains tax on share transfers does not apply, care must be taken regarding cash flow and tax treatment if fund repayments are involved.
Business tax also requires attention. Medical corporations are generally subject to business tax, but for individual practitioners, business related to social insurance medical treatment fees is tax-exempt. This difference is also an important factor when considering succession structures and tax strategies.

Business Succession Process and Keys to Success
The business succession of an internal medicine clinic is a complex process requiring specialized knowledge and thorough preparation. For success, it is essential to work with M&A experts and proceed systematically. The following outlines the general succession process and key success factors at each stage.
-
1
📋 Preparation and Consultation
Clarify the objectives and conditions for transfer and consult with M&A experts. Understand the clinic’s current status (financials, patient numbers, equipment, etc.). At this stage, it is advisable to consider compatibility with regional healthcare plans and the impact of future medical fee revisions.
-
2
🔍 Target Selection and Letter of Intent
Experts select suitable potential acquirers and approach them with a non-name sheet (anonymized information). If both parties’ intentions align, they proceed to meetings and sign a Letter of Intent (LOI). Confirmation regarding the continuity of licenses and facility standards is necessary at this stage.
-
3
📝 Due Diligence
The acquirer conducts a detailed investigation of the clinic’s financials, legal aspects, taxes, and medical system. At this stage, issues specific to medical corporations, such as the presence of equity shares, fund repayment conditions, procedures for shareholder changes, and the treatment of business tax, are thoroughly examined.
-

✅ Final Agreement and Handover
Based on the due diligence findings, negotiate the final transfer price and terms, and sign the stock transfer agreement or business transfer agreement. Subsequently, proceed carefully with the director’s change, procedures for various license modifications, explanations to patients and staff, and the handover of medical information.
