Under such process, if the Secretary does not make a decision on such a request for an exception within 10 business days of the date of the Secretary’s receipt of the request, the Secretary shall be deemed to have found the services to be medically necessary.

(2)
(A)
(i) Except as provided in paragraph (4), the Secretary shall set the fee schedules at 60 percent (or, in the case of a test performed by a qualified hospital laboratory (as defined in paragraph (1)(D)) for outpatients of such hospital, 62 percent) of the prevailing charge level determined pursuant to the third and fourth sentences of section 1395u (b)(3) of this title for similar clinical diagnostic laboratory tests for the applicable region, State, or area for the 12-month period beginning July 1, 1984, adjusted annually (to become effective on January 1 of each year) by a percentage increase or decrease equal to the percentage increase or decrease in the Consumer Price Index for All Urban Consumers (United States city average) minus, for each of the years 2009 through 2013, 0.5 percentage points, and subject to such other adjustments as the Secretary determines are justified by technological changes.
(ii) Notwithstanding clause (i)—

(B) The Secretary may make further adjustments or exceptions to the fee schedules to assure adequate reimbursement of
(i) emergency laboratory tests needed for the provision of bona fide emergency services, and
(ii) certain low volume high-cost tests where highly sophisticated equipment or extremely skilled personnel are necessary to assure quality.
(3) In addition to the amounts provided under the fee schedules, the Secretary shall provide for and establish
(A) a nominal fee to cover the appropriate costs in collecting the sample on which a clinical diagnostic laboratory test was performed and for which payment is made under this part, except that not more than one such fee may be provided under this paragraph with respect to samples collected in the same encounter, and
(B) a fee to cover the transportation and personnel expenses for trained personnel to travel to the location of an individual to collect the sample, except that such a fee may be provided only with respect to an individual who is homebound or an inpatient in an inpatient facility (other than a hospital). In establishing a fee to cover the transportation and personnel expenses for trained personnel to travel to the location of an individual to collect a sample, the Secretary shall provide a method for computing the fee based on the number of miles traveled and the personnel costs associated with the collection of each individual sample, but the Secretary shall only be required to apply such method in the case of tests furnished during the period beginning on April 1, 1989, and ending on December 31, 1990, by a laboratory that establishes to the satisfaction of the Secretary (based on data for the 12-month period ending June 30, 1988) that
(i) the laboratory is dependent upon payments under this subchapter for at least 80 percent of its collected revenues for clinical diagnostic laboratory tests,
(ii) at least 85 percent of its gross revenues for such tests are attributable to tests performed with respect to individuals who are homebound or who are residents in a nursing facility, and

(4)
(A) In establishing any fee schedule under this subsection, the Secretary may provide for an adjustment to take into account, with respect to the portion of the expenses of clinical diagnostic laboratory tests attributable to wages, the relative difference between a region’s or local area’s wage rates and the wage rate presumed in the data on which the schedule is based.
(B) For purposes of subsections (a)(1)(D)(i) and (a)(2)(D)(i) of this section, the limitation amount for a clinical diagnostic laboratory test performed—
(i) on or after July 1, 1986, and before April 1, 1988, is equal to 115 percent of the median of all the fee schedules established for that test for that laboratory setting under paragraph (1),
