Healthcare License Defense


Physicians, surgeons, osteopaths, and other medical doctors may need to address licensing issues before the Illinois Medical Board. Accusations of issues such as negligence in practice, insurance fraud, or sexual misconduct can not only affect a person’s reputation, but they could result in the suspension or revocation of a doctor’s medical license. Allegations of non-therapeutic prescribing or drug diversion could lead to both disciplinary action and criminal charges. Medicare/Medicaid compliance audits could lead to exclusion from these programs, affecting a practice’s ability to provide care to patients. Edward and Fred can help medical professionals address these issues and defend against any and all forms of discipline.
