Revenue cycle due diligence tests whether a medical practice’s reported revenue is collectible, repeatable, and supported by compliant billing. A buyer should review more than tax returns and monthly deposit totals. Claims, payer contracts, accounts receivable, denials, adjustments, credentialing, and system access determine whether cash flow will continue after ownership changes.
The purpose is not to recalculate every claim. It is to find patterns that could change the purchase price, working capital requirement, transaction structure, or decision to proceed. A practice can show healthy revenue while carrying old A/R, hidden write-offs, enrollment gaps, or income tied to a departing provider.
What Revenue Cycle Due Diligence Means
Revenue cycle due diligence is a structured review of how the target practice turns patient care into collected revenue. The reviewer follows activity from scheduling and eligibility through documentation, coding, charge capture, claim submission, adjudication, payment posting, denials, patient balances, and final account resolution.
The work should answer three questions. First, are the historical collections supported by accurate records? Second, which balances and payer relationships are likely to survive the transaction? Third, what must the buyer repair or fund immediately after closing?
Those questions require claim-level evidence. A dashboard showing a 96 percent collection rate is not enough unless the buyer knows the formula, exclusions, source system, and adjustment policy behind it. The same applies to clean claim rate, denial rate, days in A/R, and reported write-offs.
Why Financial Statements Are Not Enough
Financial statements summarize results, but they do not show how the billing operation produced them. Deposits may include delayed payments from an earlier period. Reported revenue may depend heavily on a physician who will leave. A/R may include balances that have passed filing limits or lack documentation. Contractual adjustments can also hide underpayments or preventable losses.
Compare the general ledger, practice management reports, remittance records, and bank deposits for the same periods. Differences need an explanation. For example, payments can be posted to patient accounts in one month and reach the bank in another, but the timing difference should reconcile. Unexplained gaps may point to incomplete posting, unapplied cash, refunds, payment routing problems, or weak financial controls.
Do not assume a paid claim is correct. A payer may reimburse below the contracted amount, while the remaining balance is removed as a contractual adjustment. Swift’s guide to medical billing underpayments explains why expected reimbursement must be compared with the actual claim-line result.
Documents to Request Before Reviewing the Revenue Cycle
Request consistent data covering at least several recent reporting periods, with additional history when trends or seasonality matter. Obtain the source reports rather than presentation summaries prepared for the transaction.
- Monthly charges, payments, contractual adjustments, other write-offs, refunds, and net collections by provider, location, payer, and service line.
- Detailed A/R aging with claim number, date of service, payer, balance, claim status, denial reason, last action, and next deadline.
- Claim submission, clearinghouse rejection, denial, appeal, and payment variance reports.
- Payer contracts, fee schedules, amendments, provider rosters, enrollment records, ERA and EFT configurations, and effective dates.
- Credit balance, unapplied cash, patient balance, bad debt, refund, and recoupment reports.
- Billing policies, adjustment permissions, compliance audits, payer correspondence, system agreements, and vendor contracts.
Revenue Cycle Due Diligence Checklist
Reconcile charges, collections, and bank deposits
Start with control totals. Compare completed encounters with posted charges, submitted claims, payments, adjustments, and deposits. Trace a sample from the medical record through the claim and final posting. Missing encounters can reveal charge capture problems, while differences between remittances and deposits can expose posting or reconciliation gaps.
Analyze payer mix and reimbursement
Measure payer concentration using collections, not only charges. Review reimbursement, denial frequency, payment speed, administrative burden, and contract status for major plans. Confirm whether agreements can be assigned, require notice, or require a new contracting and enrollment process.
Test accounts receivable quality
A/R is not worth its face value. Segment balances by age, payer, provider, location, status, filing limit, appeal rights, and available documentation. Sample accounts from every aging bucket, especially balances older than 90 days and large claims with repeated follow-up notes.
Separate valid, collectible claims from duplicates, credits, expired balances, unresolved denials, incorrect patient responsibility, and accounts without a documented next action. Review whether the seller will retain old A/R, transfer it, or continue collection after closing. The agreement should also assign later payments, refunds, recoupments, and patient calls. The recovery process described in Swift’s guide to accounts receivable over 90 days can help classify older claims.
Review denials, rejections, and appeals
Clearinghouse rejections never reach payer adjudication, while denials are decisions on processed claims. Confirm that reports distinguish the two. Then identify top causes, dollar impact, time to correction, appeal deadlines, repeat rates, and final outcomes.
Read account notes rather than counting touches. Notes such as “called payer” or “under review” do not prove progress. A strong record identifies the reason, action, submission channel, reference number, next follow-up date, and result. Repeated authorization, eligibility, coding, or documentation problems should connect to an upstream corrective action.
Find write-offs, adjustments, and underpayments
Review adjustment codes and user permissions. Large manual adjustments, generic write-offs, round-dollar entries, or rapid write-off and reversal activity deserve testing. Compare balances removed as contractual adjustments with applicable remittance data and fee schedules.
Also inspect zero-pay claim lines, downcoding, bundling, modifier reductions, and recurring reimbursement differences. A balance can disappear from A/R even when the practice did not receive the correct amount. Record potential recoveries separately from confirmed collectible dollars.
Verify credentialing and payer enrollment
Build a matrix of every provider, payer, plan, tax ID, NPI, location, enrollment status, and effective date. Confirm revalidation dates, pending applications, reassignment relationships, demographic updates, and unresolved enrollment-related denials.
Do not assume payer participation transfers with the acquisition. The result depends on the transaction structure, payer agreement, legal entity, provider relationships, and payer requirements. Medicare enrollment records can be reviewed through CMS PECOS, while commercial and Medicaid arrangements require their applicable processes. A buyer that needs support coordinating applications can review Swift’s medical credentialing services.
Review billing systems, clearinghouse, ERA, and EFT
List the EHR, practice management system, clearinghouse, payer portals, payment processor, statement vendor, interfaces, and reporting tools. Identify who owns each contract and whether access, data, and interfaces continue after closing.
Test coding and documentation compliance
Select claims based on risk as well as random sampling. Include major payers, high-value services, common modifiers, denied claims, adjusted claims, telehealth, new providers, and multiple locations. Compare billed codes, units, diagnosis links, place of service, and modifiers with the complete record and applicable guidance for the service date.
Review previous audits, refunds, overpayment notices, recoupments, and corrective action plans. The U.S. Department of Health and Human Services Office of Inspector General publishes general compliance program guidance that organizations can use when assessing their compliance framework. Potential disclosure, repayment, or legal issues should be handled with qualified counsel and compliance professionals.
How to Value Accounts Receivable in an Acquisition
Assigning one discount to total A/R is convenient but often misleading. Two balances at 95 days can have very different values. One may be a clean commercial claim awaiting routine processing. The other may have an expired appeal deadline and missing documentation.
Create categories based on evidence and recovery risk. Consider age, payer, status, filing and appeal rights, denial cause, documentation, enrollment, patient responsibility, prior actions, and historical recovery for similar accounts. Calculate separate estimates for current insurance A/R, old insurance A/R, patient balances, pending appeals, credits, and unapplied cash.
The purchase agreement should state who owns the balances and collection costs, who responds to record requests, how payments are identified, and who bears later refunds or recoupments. If the buyer will collect seller-owned A/R, document the fee, access period, reporting, and cutoff.
Revenue Cycle Red Flags That Can Change the Deal
Some findings are operational improvements. Others can affect value or create exposure. Warning signs include declining collections despite stable volume, a large share of A/R with no recent action, unexplained contractual adjustments, missed filing limits, provider enrollment gaps, and dependence on a payer contract that may not continue.
Watch for billing reports that cannot reconcile to deposits, denial categories that change between reports, inaccessible claim notes, generic write-offs, and metrics without definitions. A seller’s inability to produce usable claim-level data is itself a finding. It limits the buyer’s ability to validate reported performance.
Compliance concerns require immediate professional review. Examples include unsupported coding patterns, unresolved overpayments, excluded or uncredentialed individuals, incomplete audit responses, and patient information shared without appropriate controls.
How Findings Should Affect Price and Purchase Terms
Diligence findings should lead to a documented decision. A fixable billing backlog may support a transition budget and recovery project. A payer enrollment delay may require additional working capital. Uncertain A/R may be excluded from the purchase price or handled through a separate collection arrangement.
Planning the Billing Transition Before Closing
Do not wait until closing to decide how claims will move. Establish a responsibility matrix for unbilled encounters, submitted claims, rejections, denials, appeals, payments, patient balances, credits, refunds, recoupments, and record requests.
Create a cutoff that billing teams can apply at the account level. Preserve seller-system access long enough to reconcile in-flight transactions. Test claim submission, acknowledgments, remittance delivery, posting, reporting, and payment routing before full production begins.
The First 30 Days After the Acquisition
Monitor operational exceptions daily during the opening weeks. Reconcile completed encounters to charges and submitted claims. Review clearinghouse and payer acknowledgments, ERA receipt, deposits, payment posting, denials, and unresolved documentation requests.
Compare results with the diligence baseline by provider, payer, and location. Cash collected immediately after closing often reflects work completed before the transaction, so deposits alone cannot confirm that the new workflow is functioning. Submission lag, rejection queues, and missing remittances reveal problems sooner.
When to Use an Independent Medical Billing Audit
An independent review is useful when the buyer lacks claim-level expertise, reports do not reconcile, the specialty has complex coding, or the transaction includes large A/R and unresolved denials. It can also establish a neutral baseline when the seller and buyer interpret billing performance differently.
The scope should define providers, locations, payers, periods, systems, deliverables, and limitations. Swift’s medical billing audit checklist outlines the records and controls that a practice-level review should cover.
How Swift Supports Pre-Acquisition Due Diligence
Swift Medical Billing can review the target practice’s claims, A/R aging, denials, payments, adjustments, payer patterns, enrollment dependencies, and billing workflows. The objective is to distinguish sustainable collections from recoverable problems and risks that could interrupt cash flow after closing.
A review can also support the transition plan by identifying required access, legacy accounts, payer connections, reporting needs, and ownership gaps before production moves. It does not replace legal, tax, valuation, or regulatory advice.
If you are evaluating a practice acquisition, contact Swift Medical Billing to define a revenue cycle due diligence scope based on the target’s providers, systems, payer mix, locations, and outstanding A/R.
Frequently Asked Questions
What should revenue cycle due diligence include?
It should reconcile charges, claims, payments, adjustments, and deposits; test A/R quality; review denials, write-offs, underpayments, payer contracts, credentialing, coding, systems, access, and compliance history; and produce a transition plan for every open work queue.
How many years of billing data should a buyer review?
The period should be long enough to show trends, seasonality, provider changes, and payer behavior. Many reviews begin with several recent reporting periods and expand when the data reveals anomalies. The appropriate scope depends on the transaction and should be set with the buyer’s professional advisors.
Does accounts receivable transfer when a medical practice is sold?
It depends on the transaction structure and purchase agreement. The seller may retain A/R, the buyer may acquire it, or one party may collect balances for the other. The agreement should address payments, collection costs, patient communication, refunds, credits, recoupments, records, and access.
Can payer contracts and credentialing transfer to the buyer?
Not automatically. Requirements depend on the payer, agreement, legal entity, ownership change, providers, locations, and transaction structure. Confirm assignability, notices, applications, effective dates, and billing configuration with each applicable payer before closing.
Who should perform a pre-acquisition billing audit?
The team may include an experienced medical billing auditor, certified coding professionals, revenue cycle specialists, accountants, compliance advisors, and healthcare counsel. Roles should match the scope, and each professional should stay within their area of expertise.
