DSO Management Service Agreements: Invoice Review

Start with the charge you need to explain

A management service agreement, often called an MSA, can leave an owner with a simple monthly question: why is this the amount being charged? The answer should trace from a signed term through a defined input to an invoice line. A familiar percentage, a bank withdrawal or a spreadsheet sent by the service company does not complete that trace.

Begin with one period and one legal practice entity. Name the agreement, its signed amendments, the invoice date and the service dates. Record whether the amount is proposed, invoiced, approved or paid. Those are different stages. An invoice can be mathematically consistent with a spreadsheet while using the wrong month or contract definition.

The ADA's DSO agreement guide, updated in January 2021, discusses how support services, financial control and technology arrangements can differ. It is an issue-spotting guide with sample language, not a current national legal safe harbor. Have qualified health care counsel review the actual state, entities and terms before relying on a fee or control arrangement.

The broader explanation of what a DSO does helps compare the support relationship. Here the narrower decision is whether a particular charge follows the terms you have actually established. That matters before signing, during a monthly review and when preparing a sale file.

Build a definition sheet before an invoice worksheet

Do not type a formula until you can describe each input in plain language. A term such as collections might refer to a particular ledger, period, entity or payment stage. Ask for the actual definition and its supporting report. If two people supply different definitions, keep that issue open rather than selecting the one that produces the preferred answer.

Use one line for each unresolved definition. Name the person who can provide the missing document and the date needed for review. A single open question about which entity earned a receipt can matter more than pages of totals. Do not label an unsupported input as zero simply because the report has a blank cell.

Keep this sheet distinct from the commercial offer. The DSO versus private buyer comparison weighs the overall transaction. An attractive purchase price does not reconcile a later service invoice, and a corrected invoice does not settle employment, equity or purchase terms.

Work through an invented monthly invoice

The following case is fictional. Assume qualified advisers have already confirmed that the particular existing clause, entities and payment structure are lawful and applicable. The exercise does not recommend a percentage fee or establish a fee-splitting safe harbor. No number is a market quote, clinical target or standard contract term.

Under the assumed clause, the monthly service fee is the greater of a $9,000 minimum or 5% of the defined net receipt basis. An approved pass-through is added next. A separate prior service credit is applied last, after the minimum. Actual terms could define both the basis and this order differently.

The supplied receipts are before the two exclusions. Thus the basis is $200,000 minus $10,000 minus $15,000, or $175,000. The percentage calculation is $8,750. Because the assumed minimum is higher, the service fee is $9,000. Adding $1,200 and subtracting the separate $500 credit produces a corrected invoice of $9,700.

The credit has a different purpose from the two receipt exclusions. It resolves a prior service item in this invented agreement. Treating it as another receipt deduction would change the calculation and could hide its use. Keep a reference showing both the prior issue and the invoice where it was applied.

Compare the wrong basis and one independent change

Suppose the submitted invoice instead uses the $250,000 production figure as its percentage basis. Its percentage result is $12,500. With the same pass-through and credit, that invoice totals $13,200. The discrepancy is $3,500. It arises from the input definition, not from multiplication or the assumed rate.

Now test an independent change to the correct case: add $20,000 of qualifying receipts and leave both exclusions unchanged. This change is separate from the incorrect invoice. The resulting basis is $195,000. Its percentage result is $9,750, so the minimum no longer controls. The invoice becomes $10,450, which is $750 above the original corrected invoice.

The independent increase does not add the full $1,000 percentage change to the original invoice. The base percentage result sat $250 below the minimum. Part of the increase closes that gap. This is why applying a percentage only to the change can misstate an invoice with a floor.

The $10,000 cleared payment is $300 above the corrected base invoice. That is a reconciliation item to resolve under the actual documents. It does not prove a refund right, permit an offset or show that money has been returned. The wrong submitted invoice would instead show $3,200 still unpaid. Keep those competing positions visible until the underlying issue is resolved.

Make each extra charge reviewable

A correct core fee can still sit beside an unsupported extra charge. For each pass-through, identify the service, recipient, period and supporting amount. Match that evidence to the actual approval process. If a vendor bill covers several offices, obtain the allocation that places this practice's share on the invoice. Do not divide by headcount merely because it is convenient.

Ask how bundled and extra work are distinguished in the specific schedule. A billing task should not appear as both an included service and a new charge without a supported reason. A one-time migration project should have a completion basis that differs from a recurring software charge. Those are practical review questions; the answer comes from the actual agreement and work performed.

Record a disputed item without silently changing the vendor document. Keep the original, the proposed correction and the reply together. A later credit needs its own reference. Otherwise, the team may argue about the same amount in three successive months or apply the credit twice when staff change.

Before a sale, summarize material unresolved items for the approved adviser group. Use the letter of intent guide for the separate task of recording proposed deal terms. A price concession and an invoice correction need distinct treatment so the same issue is not charged to the seller twice.

Test the review process before the payment date

Set a practical sequence with the people who will do the work: receive the source report, review the calculation, resolve exceptions and document the payment decision. Use the dates and procedures in the actual documents. This guide creates no right to delay a charge, stop a withdrawal or withhold an undisputed amount.

Try the sequence on a recent invoice before depending on it at closing. The reviewer should be able to explain a line without asking the preparer to rebuild the entire month. Test a late adjustment and an invoice that spans two service periods. Decide how a correction will be carried forward and who verifies that it appears only once.

Keep access and approval as separate questions. The ability to download a bank statement is not the same as authority to release a payment. A person who prepares the calculation should not be described as the final decision maker unless the actual arrangement supports that role. Ask counsel and the bank to resolve any mismatch in the signed documents and implemented controls.

The owner also needs a backup review path. Name who receives the supporting package if the usual contact is absent. A repeatable process is more useful than a promise that a senior person will intervene whenever something goes wrong. The purpose is a supported decision at the right stage, with an evidence trail the next reviewer can follow.

Keep patient authority separate from the invoice

HHS business-associate guidance identifies billing and practice management as examples of activities that can create a business-associate relationship when they involve protected health information. For covered entities, the applicable written assurances and permitted uses need review. A commercial service description alone does not settle that privacy analysis.

HHS sample contract guidance addresses permitted uses, safeguards, subcontractors and termination handling. Its sample provisions are optional and do not alone establish a binding contract under state law. Confirm the actual arrangement, including feasible return or destruction at termination, with qualified counsel.

Use totals and anonymized examples for the initial invoice review where that meets the task. If a reviewer needs patient-level support, establish the lawful purpose, recipient and access controls first. An NDA used in a sale process is a separate document and does not grant patient-record access.

The ADA patient-autonomy principle addresses meaningful patient involvement in treatment decisions and confidentiality. It is an ethical source, not a fee formula. Keep professional care decisions outside this financial worksheet. A receipt target or a service-company dispute cannot determine the treatment a patient should receive.

Plan the final invoice while the relationship is working

Ask for an example of the final-period calculation before an exit is urgent. Does the assumed fee use service dates, receipt dates or another measure? What happens to a credit approved after the ordinary monthly cycle? Who supplies the supporting report once routine access changes? Record the contractual answers and open questions without assuming that termination cancels every later charge.

A useful exit package lists unfinished billing reviews, unapplied credits, approved projects and the expected final statement. Give each item an owner and a supporting reference. A proposed settlement amount should show which items it resolves. Otherwise, a broad closing label may conceal a charge that one party thinks remains open.

Separate this package from rollover equity terms. Investment proceeds, employment compensation and management charges can affect the same person's finances while remaining different contractual matters. Have advisers check linked provisions without merging all amounts into one unexplained net payment.

For seller outreach, begin with a blind description that omits identifying details. Obtain an NDA before disclosing the practice's identity to a prospective buyer. Time staff involvement to the work they must perform and any actual notice or participation duties. The staff communication plan helps organize that process; patient privacy still requires separate authority.

Common mistakes

The first mistake is accepting a correct calculation with an unproved basis. In the example, every multiplication in the wrong invoice works. The production input is what fails the assumed definition. Review the origin and classification of the number before debating the total.

Another mistake is combining different adjustment types. The model's receipt exclusions and prior service credit have separate purposes and places in the calculation. A general adjustment column would make the minimum harder to check and create room for duplicate use. Preserve the reason, period and calculation stage for each item.

Do not describe an open invoice difference as recovered cash. Requesting a correction, receiving agreement, posting a credit and receiving money are different events. Keep the amount and status together. Nor should the sample's percentage, minimum or order be copied into a real proposal without the needed professional review.

Finally, avoid using a deal-level concession to erase an unresolved monthly issue without a clear written link. Review the commercial settlement and invoice treatment together. A smaller purchase payment can affect the seller while the invoice still sits on the practice ledger. Each party should understand what has actually been resolved.

Summary

An MSA invoice is reviewable when the actual terms, supported inputs, order of calculation and payment status can be traced. The invented case shows a $3,500 invoice discrepancy and a separate $300 paid difference. Neither number by itself establishes a legal remedy or the value of a DSO relationship.

For a focused review, bring the signed fee schedule, one complete period of support, the submitted invoice and cleared payment evidence. Add the open questions that prevent a decision. Use a confidential consultation to organize the transaction issues and the appropriate adviser review before relying on the result.
