§ 423.600 Reconsideration by an independent review entity (IRE). ( a ) An enrollee who is dissatisfied with the redetermination of a Part D plan sponsor has a right to a reconsideration by an independent review entity that contracts with CMS. The prescribing physician or other prescriber (acting on behalf of an enrollee), upon providing notice to the enrollee, may request an IRE reconsideration. The enrollee, or the enrollee's prescribing physician or other prescriber (acting on behalf of the enrollee) must file a written request for reconsideration with the IRE within 60 calendar days after receipt of the written redetermination by the Part D plan sponsor. ( 1 ) The date of receipt of the redetermination is presumed to be 5 calendar days after the date of the Part D plan sponsor's written redetermination, unless there is evidence to the contrary.
( 2 ) For purposes of meeting the 60-calendar day filing deadline, the request is considered as filed on the date it is received by the IRE specified in the Part D plan sponsor's written redetermination.
( b ) When an enrollee, or an enrollee's prescribing physician or other prescriber (acting on behalf of the enrollee), files an appeal or a determination is forwarded to the IRE by a Part D plan sponsor, the IRE is required to solicit the views of the prescribing physician or other prescriber. ( 1 ) The IRE may solicit the views of the prescribing physician or other prescriber orally or in writing.
( 2 ) A written account of the prescribing physician's or other prescriber's views (prepared by either the prescribing physician, other prescriber, or IRE, as appropriate) must be contained in the IRE record.
( c ) In order for an enrollee or a prescribing physician or other prescriber (acting on behalf of an enrollee) to request an IRE reconsideration of a determination by a Part D plan sponsor not to provide for a Part D drug that is not on the formulary, the prescribing physician or other prescriber must determine that all covered Part D drugs on any tier of the formulary for treatment of the same condition would not be as effective for the individual as the non-formulary drug, would have adverse effects for the individual, or both.
( d ) The independent review entity must conduct the reconsideration as expeditiously as the enrollee's health condition requires but must not exceed the deadlines applicable in § 423.590, including those deadlines that are applicable when a request for an expedited reconsideration is received and granted.
( e ) When the issue is the denial of coverage based on a lack of medical necessity (or any substantively equivalent term used to describe the concept of medical necessity), the reconsideration must be made by a physician with expertise in the field of medicine that is appropriate for the services at issue. The physician making the reconsideration need not, in all cases, be of the same specialty or subspecialty as the prescribing physician or other prescriber.
( f ) The party who files a request for reconsideration may withdraw it by filing a request with the IRE.
( g ) The independent entity dismisses a reconsideration request, either entirely or as to any stated issue, under any of the following circumstances: ( 1 ) When the person or entity requesting a reconsideration is not a proper party under paragraph (a) of this section.
( 2 ) When the IRE determines the party failed to make out a valid request for reconsideration that substantially complies with paragraph (a) of this section.
( 3 ) When the party fails to file the reconsideration request within the proper filing time frame in accordance with paragraph (a) of this section.
( 4 ) When an enrollee or the enrollee's representative files a request for reconsideration, but the enrollee dies while the request is pending, and both of the following criteria apply: ( i ) The enrollee's surviving spouse or estate has no remaining financial interest in the case.
( ii ) The enrollee's representative, if any, does not wish to continue the appeal.
( 5 ) When a party filing the reconsideration request submits a timely request for withdrawal of the request for a reconsideration with the IRE.
( h ) The IRE mails or otherwise transmits a written notice of the dismissal of the reconsideration request to the parties. The notice must state all of the following: ( 1 ) The reason for the dismissal.
( 2 ) That there is a right to request that the IRE vacate the dismissal action.
( 3 ) The right to a review of the dismissal in accordance with § 423.2004.
( i ) If good cause is established, the IRE may vacate its dismissal of a request for redetermination within 6 months from the date of the notice of dismissal.
( j ) An enrollee has a right to have an IRE's dismissal reconsidered in accordance with § 423.2004.
( k ) If the IRE determines that the Part D plan sponsor's dismissal was in error, the IRE vacates the dismissal and remands the case to the Part D plan sponsor for reconsideration consistent with § 423.590. The IRE's decision regarding an Part D plan sponsor's dismissal, including a decision to deny a request for review of a dismissal, is binding and not subject to further review.
