Answer: When a Local Coverage Determination (LCD) has been retired, only those services submitted for dates on which the policy was active can be denied based on not meeting the LCD requirements. When LCDs are retired, the services are still covered and any related NCDs or coverage listed in the Internet Only Manual (IOM) will continue to apply. Although a policy may be retired, services must still be medically reasonable and necessary. The medical necessity for services provided must still be documented in the medical record.
