CMS Pub. 100-04, ch. 6, § 110.2.4
Edit for Ambulance Services
When a medically necessary transport from one SNF to another SNF occurs when the
beneficiary is discharged from the first SNF and admitted to the second, this transport is
included in consolidated billing. The first SNF is responsible for the ambulance service
and the cost is included in the Part A rate. It is not separately billable. CWF will reject
these services to the A/B MAC (B). The A/B MAC (B) must deny the service with
appeals rights.
Effective for claims with dates of service on or after April 1, 2001, CWF implemented
revisions on January 2, 2008 to bypass edit 7275 when a claim with a date of service on
or after April 1, 2001 is submitted and the date of service is within the From/Thru dates
with an occurrence Span code date of 74, 76, 77, 79, or M1 reported on a SNF inpatient
claim 21x in history or the date of service is greater than the occurrence date on a SNF
inpatient claim 21x in history with an occurrence code date of A3, B3, or C3. This will
allow for services to be separately payable outside of SNF consolidated billing during
non-covered periods in the SNF.
