Pain Management Clinic Buyer Due Diligence Checklist

Verify current DEA registration status and confirm no pending investigations or suspensions.

An inactive or suspended DEA registration halts controlled substance prescribing and can shut down the clinic entirely.

Red flag: DEA registration is under review, suspended, or subject to any active inquiry or consent agreement.

Review five years of state Prescription Drug Monitoring Program (PDMP) reports and prescribing logs.

PDMP data reveals outlier prescribing patterns that attract state medical board and DEA enforcement attention.

Red flag: Prescribing volume significantly exceeds regional benchmarks for opioid MME per patient without documented clinical justification.

Confirm all physicians hold valid, unrestricted state medical licenses and DEA schedules required for practice operations.

Restricted or probationary licenses transfer liability to the new owner and disrupt payer credentialing post-close.

Red flag: Any physician operates under a consent order, probation, or license restriction from a state medical board.

Obtain written confirmation of no prior or pending CMS or insurance fraud investigations related to controlled substance billing.

Undisclosed investigations can result in post-close recoupment demands or exclusion from Medicare and Medicaid programs.

Red flag: Seller is unresponsive or evasive when asked to provide signed representations regarding federal healthcare fraud inquiries.

Obtain a payer mix breakdown by revenue percentage across Medicare, Medicaid, commercial, and self-pay for the last three years.

Payer mix determines margin stability; heavy government payer reliance signals vulnerability to CMS rate cuts.

Red flag: More than 60% of revenue is derived from Medicare or Medicaid with no commercial payer diversification strategy.

Review all payer contracts and confirm transferability or re-credentialing requirements under a new ownership structure.

Non-assignable contracts require re-credentialing, which can take 90–180 days and disrupt cash collections post-close.

Red flag: Key commercial payer contracts contain change-of-control termination clauses with no assignment rights.

Request current reimbursement rates for top 10 CPT codes billed and compare against Medicare fee schedule benchmarks.

Above-market commercial rates may not survive renegotiation post-close, overstating normalized revenue.

Red flag: Top commercial payer rates are more than 20% above Medicare and contracts are expiring within 12 months of close.

Identify any payer audits, prepayment reviews, or reimbursement clawback demands in the past three years.

Unresolved clawbacks become buyer liability in an asset purchase if representations and warranties are insufficiently negotiated.

Red flag: Seller has received a RAC, MAC, or commercial payer audit demand with unresolved overpayment liability.

Review all physician employment agreements, compensation structures, non-competes, and termination provisions.

Weak or absent non-competes allow departing physicians to take patient panels and referral relationships to competitors.

Red flag: The founding or highest-revenue physician has no enforceable non-compete or plans to exit within 12 months of close.

Assess the revenue concentration attributed to each physician based on billed procedures and patient attribution.

Excessive dependence on a single physician creates catastrophic revenue risk if that person departs post-acquisition.

Red flag: A single physician generates more than 70% of clinic revenue with no succession plan or associate depth.

Confirm board certification status and credentials of all clinical staff performing interventional procedures.

Board certification affects payer credentialing eligibility and practice reputation within the referral network.

Red flag: A key interventional physician's board certification has lapsed or was never obtained for the relevant subspecialty.

Evaluate physician retention incentives, earnout structures, and transition timelines proposed in the deal.

Properly structured earnouts and transition agreements align physician incentives with buyer performance expectations post-close.

Red flag: Seller physicians refuse to commit to any post-close transition period or employment arrangement after the sale.

Request a full accounts receivable aging report and calculate days in AR by payer category.

High days in AR or aged balances over 120 days signal collection inefficiencies or disputed claims reducing true cash flow.

Red flag: More than 25% of outstanding AR is over 90 days old with no structured follow-up or write-off policy documented.

Audit claim denial rates by payer and top procedure codes for the trailing 24 months.

High denial rates indicate billing errors, documentation deficiencies, or payer contract disputes eroding net collections.

Red flag: Overall denial rate exceeds 15% with no active denial management process or billing staff accountable for resubmission.

Engage a medical billing compliance specialist to conduct coding accuracy review for top 20 CPT codes billed.

Systematic upcoding or unbundling of interventional procedure codes creates False Claims Act exposure transferable to the buyer.

Red flag: Internal coding review reveals systematic upcoding of nerve block or spinal injection codes without supporting documentation.

Confirm the EMR system is current, transferable, and supports compliant clinical documentation for all billed procedures.

Outdated or non-transferable EMR systems create operational disruption and documentation gaps that trigger post-close audits.

Red flag: EMR system is end-of-life, owned by the departing physician personally, or lacks exportable clinical documentation.

Confirm the proposed deal structure complies with your state's corporate practice of medicine laws and determine if an MSO structure is required.

Non-physician ownership of a professional medical corporation is prohibited in many states; improper structure voids the acquisition.

Red flag: Seller's attorney has not addressed CPOM compliance and the buyer is a non-physician entity in a CPOM-restrictive state.

Review complete malpractice claims history, open litigation, and current liability insurance coverage for the past five years.

Undisclosed malpractice claims or coverage gaps can create significant post-close financial and reputational liability.

Red flag: There are multiple unresolved malpractice claims, a pattern of settlements, or a current tail coverage gap.

Verify that facility licensure, state health department approvals, and any required procedure suite certifications are current and transferable.

Procedure suite certifications and facility licenses often require reapplication under new ownership, causing operational delays.

Red flag: Facility licensure is in the founding physician's name personally and cannot be transferred without a full re-licensure process.

Review all referral relationships to ensure compliance with Stark Law and Anti-Kickback Statute requirements.

Non-compliant referral arrangements expose the buyer to federal False Claims Act liability and Medicare exclusion risk.

Red flag: Referral arrangements with hospitals or ancillary providers lack written agreements or fair market value documentation.
