(a) Circumstance under which an aggrieved party may withdraw a complaint regarding an LCD. An aggrieved party who filed a complaint regarding an LCD may withdraw the complaint before the ALJ issues a decision regarding that LCD. The aggrieved party may not file another complaint concerning the same coverage determination for 6 months.

(b) Process for an aggrieved party withdrawing a complaint regarding an LCD. To withdraw a complaint regarding an LCD, the aggrieved party who filed the complaint must send a written withdrawal notice to the ALJ (see §426.400), CMS (if applicable), and the applicable contractor. Supplementing an acceptable complaint with new evidence does not constitute a withdrawal of a complaint, as described in §426.403.

(c) Actions the ALJ must take upon receiving a notice announcing the intent to withdraw a complaint regarding an LCD—(1) LCD reviews involving one aggrieved party. If the ALJ receives a withdrawal notice regarding an LCD before the date the ALJ issued a decision regarding that LCD, the ALJ issues a decision dismissing the complaint under §426.444 and informs the aggrieved party that he or she may not file another complaint to the same coverage determination for 6 months.

(2) LCD reviews involving joint complaints. If the ALJ receives a notice from an aggrieved party who is named in a joint complaint withdrawing a complaint regarding an LCD before the date the ALJ issued a decision regarding that LCD, the ALJ issues a decision dismissing only that aggrieved party from the complaint under §426.444. The ALJ continues the LCD review if there is one or more aggrieved party who does not withdraw from the joint complaint.

(3) Consolidated LCD reviews. If the ALJ receives a notice from an aggrieved party who is part of a consolidated LCD review withdrawing a complaint regarding an LCD before the date the ALJ issued a decision regarding that LCD, the ALJ removes that aggrieved party from the consolidated LCD review and issues a decision dismissing that aggrieved party's complaint under §426.444. The ALJ continues the LCD review if there are one or more aggrieved parties who does not withdraw from the joint complaint.
