Colin P. McCarthy Counsel

Colin concentrates his practice on healthcare compliance and reimbursement.  He counsels hospitals, health systems, surgery centers, physician practices, and other healthcare providers on the laws and regulations governing payment from Medicare, Medicaid, TRICARE, and commercial payers.

He advises healthcare clients on coverage, coding, and payment rules; Medicare Conditions of Participation; provider-based status; HIPAA; False Claims Act and “60-Day Rule;” Stark and Anti-Kickback laws; development and implementation of compliance programs; and other regulatory compliance issues.  Colin frequently helps healthcare providers undergoing changes of ownership or reorganizations navigate the state licensure, Medicare enrollment and certification, and other regulatory filings necessary to complete the transaction with minimal disruption to business operations.

Colin also represents healthcare providers facing scrutiny from government auditors and investigators, including Recovery Audit Contractors, Zone Program Integrity Contractors, state Medicaid programs, the Office of Inspector General, and the Department of Justice.  He has defended providers in dozens of administrative appeals of adverse audit results.  He also helps healthcare providers mitigate their False Claims Act risk by conducting internal compliance investigations and preparing self-disclosures to the government when necessary.

Colin frequently writes and presents on emerging reimbursement and compliance issues and is active in the American Health Lawyers Association and Health Care Compliance Association. Colin maintains an active pro bono practice through the Legal Information Network for Cancer, using his understanding of healthcare reimbursement to assist cancer patients with coverage and payment issues.
