Before you acquire a Medicare-certified home health agency, verify these critical compliance, financial, and operational factors to avoid inheriting costly regulatory and billing liabilities.
Acquiring a home health agency in the $1M–$5M revenue range requires far more scrutiny than a typical lower middle market business purchase. Beyond standard financial analysis, buyers must evaluate CMS certification status, billing compliance history, state licensure transferability, and the agency's ability to survive a change-of-ownership (CHOW) process without losing key staff or referral sources. This checklist walks through the five most critical due diligence categories every buyer should complete before signing a purchase agreement.
Verify the agency's CMS certification standing, survey history, and star ratings before any offer is finalized.
Pull the agency's CMS CASPER profile and confirm active Medicare certification with no open conditions of participation deficiencies.
A lapsed or deficient certification can halt billing and kill deal value immediately after close.
Red flag: Any open Condition-level deficiency or active Plan of Correction on the most recent survey.
Review the last three years of state and federal survey reports including all deficiency citations and correction timelines.
Repeat deficiencies signal systemic compliance failures that survive ownership changes.
Red flag: Two or more survey cycles with the same deficiency categories cited.
Confirm current CMS star ratings across quality of patient care and patient satisfaction domains.
Star ratings below three stars reduce managed care contracting eligibility and referral competitiveness.
Red flag: Overall star rating below 3.0 or a declining trend across the last four reporting periods.
Verify Medicaid certification status and confirm the agency is enrolled in all state Medicaid programs it currently bills.
Medicaid enrollment gaps can disrupt revenue continuity during CHOW re-enrollment periods.
Red flag: Medicaid enrollment lapsed or voluntarily terminated in any billed state within the past 24 months.
Audit the agency's Medicare billing practices, denial rates, and exposure to overpayment demands or fraud investigations.
Obtain a third-party billing compliance audit covering 100% of Medicare claims submitted over the last three years.
Inherited overpayment liability and RAC audit exposure can exceed purchase price in worst-case scenarios.
Red flag: Claim denial rate above 15% or any open RAC, MAC, or OIG audit or investigation.
Review OASIS accuracy rates and confirm documentation supports the PDGM grouping used for all sampled claims.
PDGM upcoding exposes the buyer to significant post-close recoupment demands from CMS.
Red flag: OASIS completion accuracy below 90% or patterns of grouper manipulation in sampled records.
Analyze EVV compliance rates by visit type and confirm the agency's EVV system meets state mandate requirements.
EVV non-compliance triggers Medicaid payment reductions and signals broader documentation risk.
Red flag: EVV compliance rate below 95% or no integrated EVV system in place at time of LOI.
Request all correspondence with CMS, MACs, and state Medicaid agencies including demand letters and repayment agreements.
Undisclosed repayment agreements become the buyer's liability in an asset or stock purchase.
Red flag: Any undisclosed demand letter or repayment plan discovered during document review.
Assess revenue quality, EBITDA sustainability, and concentration risk across Medicare, Medicaid, and private pay payors.
Reconcile three years of tax returns to internally prepared P&Ls and identify all owner add-backs and personal expenses.
Inflated EBITDA from undisclosed personal expenses directly overstates purchase price under a multiple-based valuation.
Red flag: Unexplained variances exceeding 10% between tax returns and P&L statements in any year.
Build a payor mix waterfall showing revenue percentage by Medicare, Medicaid, managed care, and private pay.
Government reimbursement above 80% of revenue creates margin compression risk under PDGM rate changes.
Red flag: Single payor accounting for more than 60% of total revenue with no diversification trend.
Analyze monthly revenue per episode and visit cost trends over 24 months against PDGM grouper benchmarks.
Declining revenue per episode signals reimbursement pressure or coding drift that will compress post-close margins.
Red flag: Revenue per episode declining more than 8% year-over-year without a corresponding cost reduction.
Confirm accounts receivable aging and identify any outstanding Medicare or Medicaid overpayment reserves on the balance sheet.
Aged AR over 120 days and unbooked overpayment liabilities are common hidden costs in home health acquisitions.
Red flag: More than 20% of AR outstanding beyond 120 days or no reserve established for known overpayment exposure.
Evaluate clinical staff qualifications, turnover rates, and the risk of losing key personnel post-close.
Audit credentials, licenses, and continuing education records for all RNs, LPNs, PTs, OTs, and home health aides.
Employing uncredentialed clinical staff voids Medicare certification and exposes the buyer to False Claims Act liability.
Red flag: Any credentialing gap or expired license found in the clinical personnel files during review.
Review trailing 12-month turnover rates for skilled nurses and therapists against national home health benchmarks.
High turnover increases recruitment costs, disrupts patient care, and signals cultural or compensation problems.
Red flag: Annual RN or PT turnover exceeding 40% or multiple therapists departing within 90 days of LOI announcement.
Confirm which key clinical and administrative staff are under employment agreements with non-solicitation provisions.
Unprotected key employees can depart post-close with patient relationships and referral source contacts.
Red flag: No employment agreements in place for the Director of Nursing or Administrator at time of LOI.
Assess owner clinical involvement and identify whether any billable visits are performed solely by the selling owner.
Owner-generated billable visits disappear at close, directly reducing post-acquisition revenue without a transition plan.
Red flag: Selling owner accounts for more than 15% of total billable visits or holds the sole Administrator license.
Map the state licensure transfer requirements and CMS change-of-ownership timeline to manage deal execution risk.
Engage a healthcare M&A attorney to map state home health licensure transfer requirements and identify any non-transferable permits.
Some states require new licensure applications rather than transfers, adding 90–180 days to deal close timelines.
Red flag: State requires de novo licensure with a certificate of need process that cannot be completed before close.
Confirm the CMS CHOW notification timeline and payor re-enrollment requirements for Medicare and all Medicaid programs.
CHOW approval gaps can interrupt Medicare billing for 60–120 days, creating significant cash flow risk post-close.
Red flag: Seller has not initiated any pre-CHOW communication with their MAC prior to signing.
Review all managed care and private pay payor contracts to determine assignment or renegotiation requirements at change of ownership.
Non-assignable managed care contracts representing 20%+ of revenue must be renegotiated, risking rate reductions or termination.
Red flag: One or more managed care contracts contain change-of-ownership termination clauses with no assignment provision.
Structure deal closing with a holdback of 10–15% of purchase price tied to successful CHOW approval and payor re-enrollment milestones.
A holdback protects the buyer if CHOW delays extend billing interruptions or if a payor terminates post-close.
Red flag: Seller refuses any holdback or escrow structure tied to CHOW completion and payor re-enrollment confirmation.

The CMS change-of-ownership process typically takes 60 to 120 days from the date the buyer submits the CHOW notification to the Medicare Administrative Contractor. State Medicaid re-enrollment timelines vary and can run concurrently or add additional time depending on the state. Buyers should structure closing to account for potential billing gaps during this window and use a holdback provision to protect against extended delays.
The most significant inherited risk is undisclosed Medicare overpayment liability from OASIS inaccuracies, PDGM upcoding, or claims submitted for services not documented in the clinical record. In a stock purchase, the buyer assumes all pre-close liability. Even in an asset purchase, CMS can pursue overpayment recoupment from the acquiring entity if billing irregularities are tied to the certification number. A third-party billing audit covering three years of claims is non-negotiable before closing.
Most buyers prefer an asset purchase to limit exposure to pre-close liabilities, but home health agencies present a unique complication: the Medicare certification and provider number are tied to the entity, not the assets. An asset purchase triggers a formal CHOW process and billing interruption, while a stock purchase allows the provider number to continue uninterrupted but transfers all historical liability. Work with a healthcare M&A attorney to evaluate which structure best balances billing continuity against compliance exposure given the specific agency's history.
Home health agencies in the $1M–$5M revenue range typically trade at 3.5x to 6x adjusted EBITDA, with the multiple driven primarily by CMS star ratings, payor mix diversification, staff stability, and clean compliance history. Agencies with strong Medicare star ratings above four stars, a census of 75 or more active patients, and no open audits or deficiencies command the higher end of the range. Heavy government payor concentration, owner dependency, or unresolved compliance issues compress multiples toward the low end or make financing through SBA 7(a) programs more difficult to secure.
