Due Diligence Guide: Acquiring a Home Health Agency

What every buyer must verify before acquiring a Medicare-certified home health agency — from CMS certification status to billing compliance, CHOW timelines, and staff retention risk.

Find Home Health Agency Acquisition Targets

Acquiring a home health agency involves layers of regulatory complexity that go far beyond standard business due diligence. Buyers must evaluate Medicare and Medicaid certification status, billing compliance history, CMS star ratings, EVV compliance, and the Change of Ownership process before committing capital. This guide outlines the critical steps for buyers targeting $1M–$5M revenue agencies with active patient census and positive EBITDA margins of 10–20%.

Home Health Agency Due Diligence Phases

01

Phase 1: Regulatory and Licensure Verification

Confirm all federal and state regulatory standing before proceeding. Licensing deficiencies or open CMS investigations can delay or kill a transaction.

Medicare and Medicaid Certification Statuscritical

Request current Medicare certification documents, CMS provider number, and any active plans of correction from recent surveys. Confirm no open enforcement actions or payment suspensions are in place.

State Licensure Transferabilitycritical

Verify state home health licensure is current and confirm with your healthcare M&A attorney whether the license transfers in an asset purchase or requires a new application triggering delays.

CMS Star Ratings and OASIS Score Reviewimportant

Pull the agency's Home Health Compare star ratings and review OASIS accuracy scores. Low ratings signal clinical documentation risk and may affect managed care contracting post-acquisition.

02

Phase 2: Financial and Billing Compliance Review

Assess revenue quality, billing integrity, and reimbursement risk. Medicare billing errors can create retroactive overpayment liability that survives an asset purchase.

Third-Party Billing Compliance Auditcritical

Commission an independent audit covering three years of Medicare claims. Review denial rates, RAC audit history, overpayment demands, and any past settlement agreements with CMS or OIG.

Payor Mix and Revenue Concentration Analysiscritical

Break down revenue by Medicare, Medicaid, managed care, and private pay. Flag agencies where a single payor or referral source exceeds 40–50% of admissions — a significant concentration risk.

PDGM Impact on Reimbursement Trendimportant

Analyze how the Patient-Driven Groupings Model has affected the agency's average episode payment over the past two years and whether margins have compressed or stabilized under the new model.

03

Phase 3: Operational and Staff Retention Assessment

Evaluate workforce stability, clinical infrastructure, and owner dependency before close. Staff defections post-acquisition can destabilize patient census and revenue within 90 days.

Key Clinical Staff Credentialing and Retention Agreementscritical

Verify licensure for all skilled nurses and therapists. Identify which staff are at-will versus contracted and negotiate retention agreements or signing bonuses for top clinical personnel before closing.

EVV Compliance and EHR Technology Reviewimportant

Confirm the agency uses a CMS-compliant Electronic Visit Verification system and a functioning EHR platform. Non-compliant EVV can trigger Medicaid payment withholding immediately post-acquisition.

Referral Source Dependency and Pipeline Documentationimportant

Map all active referral sources — hospital discharge planners, physicians, SNFs — and determine whether relationships are institutional or tied solely to the selling owner's personal relationships.

Home Health Agency-Specific Due Diligence Items

  • Request the complete CMS survey history for the past three years including all deficiency citations, plans of correction, and any Immediate Jeopardy findings that could affect certification standing.
  • Understand the full CHOW process timeline with CMS, which typically runs 30–90 days and requires buyer Medicare enrollment before any claims can be billed under the new ownership.
  • Obtain a patient census report segmented by payor, active episode status, average length of service, and referral source to validate revenue run-rate and census stability assumptions.
  • Review all employment agreements, non-solicitation clauses, and contractor arrangements for clinical staff to assess post-close turnover risk and any restrictive covenant gaps.
  • Confirm the agency's Home Health Value-Based Purchasing performance scores if operating in an HHVBP state, as quality metrics directly affect Medicare reimbursement rates going forward.

Frequently Asked Questions

How long does the CHOW process take when acquiring a home health agency?

The CMS Change of Ownership process typically takes 30–90 days after submission. Buyers should plan for billing interruptions during this window and structure deal timelines and holdbacks accordingly.

Can I use an SBA 7(a) loan to acquire a Medicare-certified home health agency?

Yes. Home health agencies are SBA-eligible businesses. Most deals are structured with SBA 7(a) financing, a 10% buyer equity injection, and a 10–15% seller note to bridge any appraisal gaps.

What is the biggest billing compliance risk when buying a home health agency?

Retroactive Medicare overpayment demands from RAC audits are the highest risk. An asset purchase limits exposure if structured correctly, but a pre-close third-party billing audit is non-negotiable.

What valuation multiple should I expect to pay for a home health agency?

Lower middle market home health agencies typically trade at 3.5x–6x EBITDA, with stronger multiples driven by high CMS star ratings, diversified payor mix, and a non-owner-dependent management team.
