Billing Procedures for a Provider Assigned Multiple Provider
100.4.1 - Billing Procedures for a Provider Assigned Multiple Provider
Numbers or a Change in Provider Number
(Rev. 267, Issued 07-30-04, Effective: 10-01-04, Implementation: 01-03-05)
Where a multiple-facility provider is assigned separate provider numbers for each component
facility or where a provider is assigned a different number, it is required to use the new
number for all notices of admission, start of care notices, bills, etc., beginning with the date
the new number is effective.
A. - Inpatient
The component provider to which the new number is assigned must apportion costs for all
patients who are inpatients in that component as of the first day of the next fiscal period
when the new provider number goes in effect. The hospital must submit a discharge bill with
the old provider number and an admission notice with the new. The date of discharge and
the date of admission are the same date, which is the first day of the new fiscal period. All
subsequent billings are submitted under the new provider number. If a no-payment situation
where the entire billing period represents charges for which no Part A payment can be made,
it is not necessary to submit a discharge bill and admission notice. In this situation, only a
final no-payment bill with a discharge date is submitted under the old provider number.
Services furnished during the "no-payment" period may subsequently be determined to be
covered. Where such covered services were furnished before the date of change in provider
number, the hospital submits one corrected bill covering the entire period showing the old
provider number. However, where services subsequently determined to be covered were
furnished after the date of change, the hospital submits a corrected discharge bill with the
old provider number and a new admission notice and billing with the new provider number.
Effective October 1, 2004, there are new rules pertaining to long term care hospitals. (See
section 150.14.1).
B. - Outpatient Services, Part B Ancillary Services and Home Health Agency Services
For outpatient services and Part B ancillary services, and home health agency services, the
provider uses the old provider number for services provided up through the day before the
effective date of the new provider number. Thereafter, it uses the new number when
submitting bills.
