Why is there a 30 calendar day deadline for bidder inquiry submission and why are bidders only allowed to submit one inquiry?

The Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) Section 522 and 42 CFR §414.412(g) requires CMS to return the bid surety bond liability within 90 days of the public announcement of contract suppliers. The bid surety bond forfeiture conditions under 42 CFR §414.412(g)(3) apply to bidding entities that are offered a contract for a competitive bidding area and product category combination(s), including those that receive a contract offer(s) as a result of the bidder inquiry process.  As a result, limiting bidders to one bidder inquiry submission within a 30 calendar day deadline is needed to allow CMS to re-evaluate all bid disqualification reasons and, if necessary, issue contract offers within 90 days of the public announcement of contract suppliers.
