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.
