§ 405.1803 Contractor determination and notice of amount of program reimbursement.
(a) General requirement. Upon receipt of a provider's cost report, or amended cost report where permitted or required, the contractor must within a reasonable period of time (as specified in § 405.1835(c)(1)), furnish the provider and other parties as appropriate (see § 405.1805) a written notice reflecting the contractor's final determination of the total amount of reimbursement due the provider. The contractor must include the following information in the notice, as appropriate:
(1) Reasonable cost. The notice must—
(i) Explain the contractor's determination of total program reimbursement due the provider on the basis of reasonable cost for the reporting period covered by the cost report or amended cost report; and
(ii) Relate this determination to the provider's claimed total program reimbursement due the provider for this period.
(2) Prospective payment. With respect to a hospital that receives payments for inpatient hospital services under the prospective payment system (see part 412 of this chapter), the contractor must include in the notice its determination of the total amount of the payments due the hospital under that system for the cost reporting period covered by the notice. The notice must explain (with appropriate use of the applicable money amounts) any difference in the amount determined to be due, and the amounts received by the hospital during the cost reporting period covered by the notice.
