Participation with the PHP is confidential but there may be other parties to which you must report your participation because of contractual obligations you’ve assumed.  Check your contracts to see if you have agreed to notify any entity with regards to changes in your practice (e.g. diagnosis/treatment for addiction or mental/physical impairment).  Your hospital bylaws, malpractice insurance policy, and/or health insurance payor contracts may all have notice provisions requiring you to report your participation with the PHP.
