60 - Billing Procedures for a Composite SNF or a Change in Provider Number (Rev. 767, Issued: 12-02-05, Effective: N/A, Implementation: N/A) SNF-520, A3-3600.5 A hospital with a sub-provider that meets the criteria for a composite distinct part SNF defined in 42 CFR 483.5 is required to use the single SNF number assigned for all claims, beginning with the date the provider number is effective. Where there is a change of ownership (CHOW), and the new owner refuses assignment of the existing provider agreement, the old owner submits all claims for periods prior to the CHOW using the old provider number. The new owner submits claims for services rendered after the date of the CHOW using the new provider number. Also with respect to CHOWs, the SNF submits a bill with the old provider number for the period before the change and another with the new provider number for the period after the change. The date of discharge on the first bill and the date of admission on the second bill are the same, which is the effective date of the new provider number. All subsequent billings are submitted under the new provider number.
