2

We conduct diligence across payor contracts, Medicare and Medicaid enrollment, compliance program maturity, malpractice history, physician employment agreements, and patient volume concentrations to surface risks before closing.

4

Purchase Agreement and Ancillary Documents

We negotiate the purchase agreement, physician employment or non-compete terms, transition services arrangement, and earnout provisions tied to clinical performance metrics specific to the practice type.

5

Closing and Clinical Continuity

Questions to Ask Any M&A Attorney Before Hiring

Use these before you call any firm, including ours.

1. "Who will actually handle my transaction?"

At many firms, a partner sells the work and a junior associate does it. Ask for the name of the attorney who will draft and negotiate your documents.

2. "How many M&A transactions has the lead attorney closed in the past 12 months?"

Volume indicates current, active deal experience, not just credentials from years ago.

3. "What is your experience with my deal size and industry?"

A $500K SBA acquisition and a $50M PE deal require different skill sets. Make sure the attorney has handled transactions similar to yours.

4. "Will you coordinate with my CPA, financial advisor, and broker?"

M&A transactions require a team. Your attorney should work with your other advisors, not in a silo.

5. "How do you handle post-closing disputes?"

Reps, warranties, and indemnification claims surface months after closing. Ask whether the firm handles post-closing litigation or refers it out.

6. "What is your fee structure, and what drives cost?"

Ask how the engagement is scoped, what is included, and what factors drive cost increases. Defined scope with a retainer gives the clearest cost picture.

Frequently Asked Questions

Common questions from Chicago clients

What does a medical practice attorney do?
A medical practice attorney handles the legal and regulatory side of buying or selling a physician practice. This includes structuring the deal to comply with Corporate Practice of Medicine rules, conducting diligence on payor contracts and Medicare enrollment, negotiating the purchase agreement and physician employment terms, and coordinating provider number transfers. At Acquisition Stars, Managing Partner Alex Lubyansky personally handles every physician practice transaction.
What is a staged acquisition of a medical practice?
A staged acquisition is a common structure where the buyer acquires an initial ownership percentage, often 51%, with a contractual right or obligation to purchase the remaining interest over time. This structure lets the buyer begin building equity while the seller transitions gradually, and it can align incentives around patient retention and practice performance. The legal documents must carefully address buy-in price, trigger conditions, and each party's rights during the interim period.
How does Corporate Practice of Medicine affect a physician practice acquisition?
Most states restrict ownership of medical practices to licensed physicians. When a non-physician buyer is involved, the deal typically requires a Management Services Organization structure that separates the clinical entity from the business operations. In strong CPOM states, the structure must hold up under state scrutiny while still delivering the economic deal the parties negotiated. We design structures that work in your specific state.
What happens to Medicare and Medicaid enrollment when a practice is sold?
Medicare and Medicaid provider numbers and enrollment do not automatically transfer to a new owner. Depending on the transaction structure, the buyer may need to file a Change of Ownership (CHOW) with CMS, apply for new enrollment, or reassign billing privileges. The timing of these filings directly affects cash flow after closing. We build the provider number transition into the deal timeline so reimbursement does not stall.
Can a physician buy the practice they currently work at?
Yes, and it is one of the most common physician practice transactions we handle. The physician already knows the patient base, the payor mix, and the operations, which simplifies due diligence but creates its own negotiating dynamics. Key issues include how the practice is valued relative to the physician's existing compensation, how a transition period is structured if the selling physician stays on, and how non-compete terms are written to reflect the physician's prior relationship with the practice.
What can I expect during an initial consultation in Chicago?
During your confidential initial consultation in Chicago, we'll discuss your medical practice acquisition law needs, review your current situation, assess potential challenges specific to Illinois, and outline a clear path forward. We'll explain our process, answer your questions, and determine if we're the right fit for your needs.
Do you work with companies outside of Chicago?
Yes, we represent clients nationwide while maintaining a strong presence in Chicago. Our managing partner handles medical practice acquisition law matters across all 50 states, coordinating with local counsel where state-specific requirements apply.

The Chicago M&A Market

Chicago is the Midwest's M&A powerhouse, with deep deal activity in manufacturing, food & beverage, financial services, and healthcare. The city's central location and transportation infrastructure make it a hub for logistics and distribution company acquisitions. Chicago's robust private equity community - including firms like GTCR, Madison Dearborn, and Duchossois Capital - drives significant lower middle-market deal flow.

Top M&A Sectors in Chicago

  • Manufacturing
  • Food & Beverage
  • Financial Services
  • Healthcare
  • Logistics & Distribution

Deal Environment

Chicago offers a balanced deal market with strong fundamentals - valuations are more reasonable than coastal markets while target quality remains high. The region's manufacturing base creates consistent opportunities for PE-backed platform builds.

Why Acquire in Chicago

The Chicago metro area's diversified economy and central location make it ideal for platform acquisitions with national expansion potential. The region's deep talent pool in engineering, finance, and operations supports post-acquisition growth.

Illinois Legal Considerations

Illinois enacted strict non-compete reform in 2022 - agreements are unenforceable for employees earning under $75,000 (increasing annually), and employers must advise employees to consult counsel before signing, affecting how buyers retain key personnel post-acquisition.
