When two or more appellants submit a request for hearing, the ALJ or attorney adjudicator determines the amount in controversy in accordance with § 405.1006(d) and (e) of this chapter.
2. (b)If the ALJ or attorney adjudicator determines that the amount in controversy is less than $200, the ALJ, without holding a hearing, or attorney adjudicator notifies the parties that the parties have 15 calendar days to submit additional evidence to prove that the amount in controversy is at least $200.
3. (c)At the end of the 15-day period, if an ALJ determines that the amount in controversy is less than $200, the ALJ, without holding a hearing dismisses the request for a hearing without ruling on the substantive issues involved in the appeal and notifies the parties and the QIO that the QIO reconsidered determination is conclusive for Medicare payment purposes.
