Healthcare Audits, Investigations, and Enforcement

Audit, Appeal, and Investigation Counsel for Providers and Healthcare Businesses

Audits, investigations, and payor disputes can create significant legal and financial pressure for providers, suppliers, and healthcare businesses. In many cases, these matters also involve reimbursement concerns, licensing issues, contractual conflicts, or other regulatory matters that affect daily operations and long-term business stability.

Fish Healthcare Law represents providers, suppliers, and healthcare businesses in payor audits, overpayment and recoupment disputes, Medicare and Medicaid enrollment actions and appeals, self-disclosures, professional licensing matters, and government inquiries. Nathan Fish is Board Certified in Health Law by the Texas Board of Legal Specialization and has more than 15 years of experience advising healthcare clients on regulatory, compliance, and transactional matters.

Where a matter proceeds to litigation, Nathan works with the client’s litigation counsel on the underlying regulatory issues.

Representative Audit, Appeal, and Enforcement Matters

Healthcare disputes often combine reimbursement, compliance, enrollment, licensing, and operational concerns. Representative matters include:

· Commercial and Medicaid managed care payor audits, special investigations unit (SIU) inquiries, overpayment demands, and recoupment disputes

· Medicare audits by MACs, UPICs, RACs, and other CMS contractors, and appeals through the Medicare administrative appeals process

· Medicare and Medicaid enrollment denials, revocations, and terminations, including corrective action plans, reconsiderations, and appeals, and rebuttals of Medicare billing privilege deactivations

· Compliance counseling on False Claims Act exposure, including identification, reporting, and return of overpayments under the 60-day rule

· Disclosures of potential Stark Law violations under the CMS Voluntary Self-Referral Disclosure Protocol (SRDP)

· Disclosures under the OIG Health Care Fraud Self-Disclosure Protocol

· Investigations and disciplinary matters before the Texas Medical Board and other Texas licensing boards, including appeals of adverse licensure actions

· Internal investigations and

· HIPAA breach response, including breach risk assessments and required notifications

These matters frequently involve the Stark Law, the Anti-Kickback Statute, HIPAA, the HITECH Act, billing and overpayment obligations, physician self-referral concerns, and False Claims Act exposure.

Regulatory and Compliance-Related Disputes

Healthcare organizations operate within a highly regulated environment shaped by federal and state laws, reimbursement requirements, licensing obligations, and privacy regulations. Fish Healthcare Law assists clients responding to disputes and investigations involving:

· Healthcare compliance concerns

· Billing and reimbursement issues

· Licensing and disciplinary matters

· Regulatory inquiries and investigations

· Government investigations

· Corporate integrity agreements

Matters may involve CMS and its contractors (including MACs, UPICs, and RACs), the HHS Office of Inspector General, the HHS Office for Civil Rights, state Medicaid agencies and their contractors, commercial and managed care payors, the Texas Medical Board and other Texas licensing boards, the FDA, and the Drug Enforcement Administration.

When Audits and Investigations Affect the Business

An audit, enforcement action, or regulatory matter can affect far more than the outcome of a single proceeding. Investigations, payor audits, reimbursement disputes, and government enforcement actions may create financial strain, reputational concerns, and disruption to ongoing business activities.

Fish Healthcare Law advises healthcare businesses on transactional and operational issues that arise from or intersect with these matters, including:

· Joint ventures and mergers and acquisitions involving pending audits, investigations, or overpayment exposure, including related disclosure, indemnification, and escrow terms

· Physician compensation arrangements

· Corporate reorganizations

· Restructuring arrangements that raise corporate practice of medicine, Stark Law, or Anti-Kickback Statute concerns

· Regulatory due diligence and successor-liability issues in healthcare transactions

· Compliance program development and remediation

Industry-Focused Healthcare Regulatory Counsel

Audits, investigations, and payor disputes involving healthcare organizations often intersect with reimbursement rules, referral relationships, privacy obligations, contractual issues, and operational policies.

Even relatively routine matters can create broader financial, regulatory, or reputational concerns if they are not handled strategically. Providers and healthcare businesses often need counsel who understands how these matters may affect operations, payor relationships, licensing, and long-term business goals — and who can work alongside litigation counsel when regulatory issues are at the heart of the dispute.

Fish Healthcare Law provides healthcare-focused representation informed by more than 15 years of experience advising healthcare and life sciences clients on regulatory, compliance, and transactional matters. Nathan Fish works closely with clients to develop legal strategies aligned with both immediate legal concerns and long-term business objectives.
