Buying a Practice From a Retiring Pulmonologist
Buying a practice from a retiring pulmonologist can be one of the most practical paths to ownership. A retiring pulmonologist often has a loyal patient base, long-standing referral relationships and an experienced staff, and many are looking for a successor who will continue caring for their patients. For the buyer, the opportunity can mean stepping into an established practice rather than building one from scratch.
Retirement sales also carry specific risks. Much of the practice’s value may be tied to the selling physician personally, and once that physician leaves, patients and referral sources may need time to build trust with someone new. This guide explains what to look for and how to plan the transition and financing. Nothing here is legal, tax, billing or compliance advice, and rules on licensing, enrollment and ownership vary by state and payer.
Why Retirement Sales Are Different
When a physician sells to join a larger group or relocate, the practice may already have systems that run without the owner. A retirement sale is often different. The selling physician may have built the practice over many years and may still:
- See a large share of the patients personally
- Hold the key referral relationships with primary care physicians and hospitals
- Interpret most of the testing performed in the office
- Manage hospital coverage, directorships or call arrangements
- Make most business decisions without written procedures
Understanding how much of the practice depends on the retiring pulmonologist is the first step in evaluating the opportunity.
Evaluating the Practice
Patient Base
Review the active patient count, the mix of conditions treated and how often patients return. A pulmonology practice that manages many chronic conditions, such as chronic obstructive lung disease, asthma and interstitial lung disease, may have patients who return regularly. That continuity can support value, but only if patients are comfortable continuing with a new physician.
Referral Sources
Identify which physicians and health systems send new patients and how long those relationships have lasted. Ask whether the seller is willing to make personal introductions before and after closing.
Hospital Arrangements
If the seller holds stipends, directorships or critical care coverage contracts, find out whether they can be assigned or whether the hospital will need to approve a new physician. Our article on pulmonology hospital contracts explains how lenders tend to view that income.
Equipment and Facility
Retiring physicians sometimes delay equipment upgrades in their final years of practice. Review the age and condition of pulmonary function testing systems, sleep testing devices and office technology, and plan for replacement costs if needed. Our guide to buying a pulmonology practice includes a broader due diligence checklist.
Planning the Transition With a Retiring Pulmonologist
A clear transition plan can protect the value you are paying for. Buyers and sellers often agree on:
- A period during which the seller continues to work part-time or remains available
- Joint introductions to patients, staff and referral sources
- A communication plan announcing the change, reviewed by counsel
- Coordination of medical records custody and patient notification requirements
- Timing for updating payer enrollments, credentialing and hospital privileges
Payer contracts, Medicare and Medicaid enrollments and credentialing should not be assumed to transfer. Healthcare counsel and qualified billing professionals can help plan the steps. The transition role, compensation and any restrictive covenants should be documented in the purchase agreement with the help of counsel.
Retaining Staff
Long-tenured staff often hold the practice together during an ownership change. Front desk staff know the patients, technologists know the testing workflows and billing staff know the payers. Meeting with staff early, explaining your plans and addressing concerns about pay and schedules can reduce turnover. Worker classification and compensation structures should be reviewed by qualified professionals.
Valuing a Retirement Sale
Because so much of the value may depend on the seller, buyers should look closely at how earnings are calculated and how much income is likely to continue. Hospital income, ancillary revenue and the seller’s personal production should each be considered. Our article on pulmonology practice valuation explains the main factors.
Financing the Purchase
Most buyers finance part of the price. Options may include SBA 7(a) loans, conventional practice loans and seller financing. SBA eligibility and terms depend on the business, the buyer, use of proceeds, program rules and lender review, and every loan is subject to approval.
Some retiring physicians are open to carrying a portion of the price as a seller note. Lenders and programs may limit how that note is structured, and seller notes are typically subordinate to the senior loan. Lenders and programs may also limit earnouts tied to future performance.
Lenders reviewing a retirement sale will pay close attention to the transition plan, since they want confidence that revenue will continue after the seller leaves. Our pulmonology practice acquisition financing guide explains how lenders review these deals.
If the Seller Owns the Building
Retiring physicians often own the building their practice occupies. The buyer may purchase the property, lease it from the seller or negotiate an option to buy later. Each choice affects the size of the loan and long-term costs.
Mistakes to Avoid
- Assuming patients will stay without a planned introduction period
- Counting the seller’s hospital income as transferable without confirmation
- Overlooking deferred equipment upgrades
- Waiting too long to begin enrollment and credentialing steps
- Leaving too little working capital for the first months after closing
Final Thoughts
Buying a practice from a retiring pulmonologist can offer an established foundation, but success depends on how well the transition is planned. A thoughtful handoff of patients, referral sources and staff, combined with financing that leaves room for the adjustment period, can help protect the practice’s value.
