Due Diligence Checklist for Buying a Mental Health Private Practice

Review all clinician employment agreements, compensation structures, and non-compete or non-solicitation clauses.

Unprotected clinicians can depart and take client panels, eliminating revenue overnight.

Red flag: No written employment agreements or non-solicitation clauses exist for any clinician on staff.

Map revenue concentration by clinician — identify what percentage each provider generates of total collections.

Heavy dependence on one or two clinicians creates catastrophic downside if they exit post-acquisition.

Red flag: A single clinician, especially the selling owner, drives more than 40% of total practice revenue.

Conduct confidential retention interviews or assess tenure data to gauge clinician satisfaction and flight risk.

Therapist turnover is expensive and disrupts client continuity, referral pipelines, and payer credentialing.

Red flag: Multiple clinicians have tenures under 12 months or recent departures are unexplained by the seller.

Confirm whether clinicians are employees or independent contractors and verify proper classification compliance.

Misclassified contractors create IRS liability and limit your ability to enforce non-solicitation terms.

Red flag: All or most clinicians are classified as 1099 contractors with no behavioral controls or written agreements.

Obtain and review active credentialing status for every billable clinician across all insurance panels.

Billing a non-credentialed clinician triggers claim denials, recoupments, and potential fraud liability.

Red flag: One or more clinicians are billing under another provider's NPI or are provisionally credentialed only.

Confirm whether payer contracts are assignable in an asset purchase or require re-enrollment post-closing.

Re-enrollment gaps of 60–180 days can create severe cash flow disruption during the transition period.

Red flag: Key commercial payers confirm contracts are non-assignable and panels in the region are currently closed.

Analyze payer mix breakdown — commercial insurance, self-pay, Medicare, Medicaid — by percentage of revenue.

Heavy Medicaid concentration signals low reimbursement rates, audit risk, and limited margin expansion.

Red flag: Medicaid represents more than 40% of collections with no strategic plan to diversify the payer mix.

Review accounts receivable aging report and average days to collect by payer category.

High AR aging signals billing inefficiency, payer disputes, or systemic undercoding across the practice.

Red flag: More than 25% of AR is aged beyond 90 days or a single payer represents a large disputed balance.

Request evidence of a formal HIPAA risk assessment completed within the past 24 months.

Absence of a documented risk assessment is itself an HHS violation and signals systemic compliance gaps.

Red flag: No HIPAA risk assessment has ever been conducted or documentation cannot be located by the seller.

Review the EHR system in use, data migration feasibility, and whether the platform is cloud-based and HIPAA-compliant.

Outdated or paper-based systems create transition costs and ongoing compliance and audit vulnerabilities.

Red flag: The practice uses paper records or a non-certified EHR with no structured data export capability.

Confirm whether any prior HIPAA breaches, OCR complaints, or state licensing board investigations have occurred.

Undisclosed breaches create successor liability and reputational damage that can surface post-closing.

Red flag: Seller discloses a prior breach but cannot provide documentation of remediation steps taken afterward.

Audit a sample of clinical records for documentation completeness, session notes, and supervision sign-offs.

Incomplete clinical documentation triggers payer audits, recoupments, and potential licensure sanctions.

Red flag: Session notes are consistently missing, unsigned, or completed weeks after the date of service.

Obtain three years of tax returns, P&L statements, and bank statements for reconciliation and normalization.

Owner add-backs, cash transactions, and misclassified expenses commonly inflate reported EBITDA.

Red flag: Tax returns and internal P&Ls show material discrepancies with no clear explanation from the seller.

Calculate net collections rate — actual collections divided by allowable charges — by payer and by clinician.

A net collections rate below 90% signals systemic billing problems that compress true practice profitability.

Red flag: Collections rate is below 85% and the seller attributes losses to write-offs without detailed reconciliation.

Review billing workflows, clearinghouse relationships, and whether billing is handled in-house or outsourced.

Disorganized billing operations create revenue leakage that a buyer inherits immediately upon closing.

Red flag: Billing is managed informally by the owner or a part-time staff member with no documented processes.

Assess telehealth revenue as a percentage of total collections and evaluate reimbursement rate trends by payer.

Telehealth parity laws vary by state and temporary pandemic-era rates may compress margins going forward.

Red flag: More than 60% of sessions are telehealth with no analysis of rate sustainability post-PHE expiration.

Engage a healthcare attorney to review state corporate practice of medicine and psychology laws before LOI.

Many states prohibit non-licensed individuals or corporations from owning a clinical mental health practice.

Red flag: The seller is unaware of CPOM restrictions and no healthcare attorney has been involved in deal structuring.

Review the entity structure, operating agreements, and any existing ownership interests or investor agreements.

Undisclosed minority partners or lien holders can block a clean asset or equity transfer at closing.

Red flag: Operating agreement references silent partners, profit interests, or outstanding convertible obligations.

Confirm all state and local business licenses, clinical facility licenses, and DEA registrations are current.

Lapsed licenses can trigger billing suspensions or require re-application with lengthy processing delays.

Red flag: A clinical license or facility certification has lapsed or is currently under a renewal review by regulators.

Review all office leases for assignment provisions, personal guarantees, and remaining term and renewal options.

A short-term lease without renewal options creates relocation risk and disrupts established patient access.

Red flag: The primary office lease expires within 18 months with no renewal option and landlord consent required.
