§ 426.523 Withdrawing a complaint regarding an NCD under review.
(a) Circumstance under which an aggrieved party withdraws a complaint regarding an NCD. An aggrieved party who filed a complaint regarding an NCD may withdraw the complaint before the Board issues a decision regarding that NCD. 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 NCD. To withdraw a complaint regarding an NCD, the aggrieved party who filed the complaint must send a written withdrawal notice to the Board (see § 426.500) and CMS. Supplementing an acceptable complaint with new evidence does not constitute a withdrawal of a complaint, as described in § 426.503.
