[Code of Federal Regulations] [Title 21, Volume 8] [Revised as of April 1, 2003] From the U.S. Government Printing Office via GPO Access [CITE: 21CFR822.15] [Page 160-161] TITLE 21--FOOD AND DRUGS CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN SERVICES (CONTINUED) PART 822--POSTMARKET SURVEILLANCE--Table of Contents Subpart C--Postmarket Surveillance Plan Sec. 822.15 How long must I conduct postmarket surveillance of my device? The length of postmarket surveillance will depend on the postmarket surveillance question identified in our order. We may order prospective surveillance for a period up to 36 months; longer periods require your agreement. If we believe that a prospective period of greater than 36 months is necessary to address the surveillance question, and you do not agree, we will use the [[Page 161]] Medical Devices Dispute Resolution Panel to resolve the matter. You may obtain guidance regarding dispute resolution procedures from the Center for Devices and Radiological Health's (CDRH) Web site (www.fda.gov/cdrh/ resolvingdisputes/ombudsman.html) and from the CDRH Facts-on-Demand system (800-899-0381 or 301-827-0111, document number 1121). The 36- month period refers to the surveillance period, not the length of time from the issuance of the order.
