Selling Your Practice to a DSO, MSO, or PPM: What to Expect

Unsolicited offers to buy medical and dental practices are common again, and most of them come from three types of buyers that get abbreviated with three letters. DSO. MSO. PPM. Each one behaves differently, structures deals differently, and produces a different life after close. An owner-doctor in Idaho or Utah who receives one of these letters in the mail deserves to know which type of buyer is on the other end of the conversation before signing an LOI.

The mistake most owners make is treating the three as interchangeable. They are not. This piece walks through the structural differences, how deal consideration usually gets split between cash, rollover equity, and post-close comp, the EBITDA adjustments buyers push during diligence, the tax treatment that actually changes take-home, and what life looks like after the ink dries.

DSO vs. MSO vs. PPM: The Structural Differences

A dental support organization (DSO) is the dental industry’s version of a management services company. In most states, a DSO cannot own the clinical entity outright due to corporate-practice-of-dentistry rules, so it typically buys the practice’s non-clinical assets and enters a management services agreement with the dentist-owned professional entity.

A management services organization (MSO) is the medical equivalent, structured similarly around corporate-practice-of-medicine restrictions. The MSO owns the non-clinical business; the physicians retain the clinical entity and contract with the MSO for management services.

A physician practice management company (PPM) is a broader term for larger, often publicly traded, physician management platforms. Some PPMs are private-equity-backed roll-ups; others are hospital-affiliated. The economics vary.

The abbreviation matters because it shapes what the buyer can and cannot own, how the deal must be structured, and how much post-close autonomy the physician retains over clinical decisions.

How Deal Consideration Is Split (Cash, Rollover, Earnout, Comp)

The headline price is rarely what the seller receives at closing. A typical DSO or MSO deal splits consideration four ways:

• Cash at closing, usually 60 to 80% of the total enterprise value
• Rollover equity in the acquiring platform, held until a future “second bite” liquidity event
• Earnouts tied to post-close performance targets
• Ongoing physician compensation, negotiated as part of the employment agreement

Cash at closing is real money. Rollover equity is a lottery ticket that pays if the platform sells again at a higher multiple, and pays nothing if the platform stalls. Earnouts pay if targets are hit and lose disputes at the moment of measurement. Post-close comp is often the largest single line item over the life of the deal, and it is the number the seller controls least.

EBITDA Adjustments the Buyer Will Push

Buyers do not pay a multiple on the practice’s reported earnings. They pay a multiple on adjusted EBITDA, and the adjustment negotiation is where deal value moves. Common adjustments buyers push during diligence:

• Reducing owner-doctor comp to a market-rate replacement salary (this raises EBITDA and price)
• Backing out one-time expenses (legitimate) and recurring expenses claimed as one-time (contested)
• Normalizing rent to fair market value if the practice pays above-market to a related landlord
• Adding back personal-use expenses run through the practice

The direction of these adjustments is usually favorable to the seller in the aggregate. The seller who does not have a CPA running the adjustment math independently is negotiating without a floor.

The Tax Treatment That Actually Changes Your Take-Home

Federal tax treatment can move the seller’s after-tax take-home by 10 to 20 percentage points depending on how the deal is structured. Three common structures:

An asset sale generally produces ordinary income on depreciation recapture and capital gain on goodwill. It is common in DSO deals because the buyer wants a stepped-up basis and the practice entity is a professional entity that cannot be acquired directly.

A stock or membership interest sale generally produces capital gain to the seller and gives the buyer carryover basis. Simpler tax treatment for the seller; less attractive to the buyer.

An F-reorganization is a specific structure that lets an S corporation seller achieve a mostly capital-gain outcome while still delivering a buyer-friendly asset-purchase structure. It is common in higher-value practice deals and worth understanding in advance.

Life After Close: Autonomy, Culture, and Comp

The physician who sells to a DSO or MSO does not usually stop working the next day. Most deals require a post-close employment or services agreement of three to five years. What that life looks like depends heavily on the acquirer’s operating model.

Two questions worth asking every acquirer during diligence:

• What decisions do the physicians in your existing acquired practices make, and what decisions have moved to corporate?
• How does the compensation model change post-close, and what is the actual take-home difference for the physicians in year three?
