IPPS Transfers Between Hospitals
40.2.4 - IPPS Transfers Between Hospitals
(Rev.10952, Issued:08-19-2021, Effective: 09-20-2021, Implementation:09-20-2021)
A discharge of a hospital inpatient is considered to be a transfer if the patient is admitted the
same day to another hospital. A transfer between acute inpatient hospitals occurs when a
patient is admitted to a hospital and is subsequently transferred from the hospital where the
patient was admitted to another hospital for additional treatment once the patient's condition
has stabilized or a diagnosis established. The following procedures apply. See §20.2.3 for
proper Pricer coding to ensure that these requirements are met.
Note: CMS established Common Working File Edits (CWF) edits in January 2004 to ensure
accurate coding and payment for discharges and/or transfers.
A. - Transfers Between IPPS Prospective Payment Acute Care Hospitals
For discharges occurring on or after October 1, 1983, when a hospital inpatient is discharged
to another acute care hospital, as described in 42 CFR 412.4(b), payment to the transferring
hospital is based upon a graduated per diem rate (i.e., the prospective payment rate divided
by the geometric mean length of stay for the specific MS-DRG into which the case falls;
hospitals receive twice the per diem rate for the first day of the stay and the per diem rate for
every following day up to the full MS-DRG amount). If the stay is less than l day, l day is
paid. A day is counted if the patient was admitted with the expectation of staying overnight.
However, this day does not count against the patient's Medicare days (utilization days), since
this Medicare day is applied at the receiving hospital. Deductible or coinsurance, where
applicable, is also charged against days at the receiving hospital (see §40.1.D). If the patient
is treated in the emergency room without being admitted and then transferred, only Part B
billing is appropriate. Payment is made to the final discharging hospital at the full
prospective payment rate.
The prospective payment rate paid is the hospital's specific rate. Similarly, the wage index
values and any other adjustments are those that are appropriate for each hospital. Where a
transfer case results in treatment in the second hospital under a MS-DRG different than the
MS-DRG in the transferring hospital, payment to each is based upon the MS-DRG under
which the patient was treated. For transfers on or after October 1, 1984, the transferring
hospital may be paid an outlier payment. For further information on outlier payments for
transfer cases, see section 20.1.2.4 of this manual.
An exception to the transfer policy applies to MS-DRG 789. The weighting factor for this
MS-DRG assumes that the patient will be transferred, since a transfer is part of the
definition. Therefore, a hospital that transfers a patient classified into this MS-DRG is paid
the full amount of the prospective payment rate associated with the DRG rather than the per
diem rate, plus any outlier payment, if applicable.
Effective for discharges on or after October 1, 2003, patients who leave against medical
advice (LAMA), but are admitted to another inpatient PPS hospital on the same day as they
left, will be treated as transfers and the transfer payment policy will apply.
An acute care transfer occurs when a Medicare patient in an IPPS Hospital (with any MS-
DRG) is:
• Transferred to another acute care IPPS hospital or unit for related care (Patient
Discharge Status Code 02 or Planned Acute Care Hospital Inpatient Readmission
Patient Discharge Status Code 02).
• Admitted to another IPPS on the same day after leaving their designated IPPS
hospital against medical advice (Patient Discharge Status Code 07).
• Discharged but then readmitted on the same day to another IPPS hospital (unless the
readmission is unrelated to the initial discharge).
B. - Transfers from an IPPS Acute Care Hospital to Hospitals or Hospital Units
Excluded from the IPPS
When patients are transferred to hospitals or units excluded from IPPS, the full inpatient
prospective payment is made to the transferring hospital. The receiving hospital is paid on
the basis of reasonable costs or is made at the rate of its respective payment system (see
exceptions in paragraph C of this section).
A transfer payment is made to the transferring hospital when patients are transferred to a
hospital that would ordinarily be paid under prospective payment, but that is excluded
because of participation in a state or area wide cost control program. Also, a transfer
payment is made where a patient is transferred to a hospital or hospital unit that has not been
officially determined as being excluded from PPS and certain hospitals that are excluded
from IPPS. These include:
• An acute care hospital that would otherwise be eligible to be paid under the IPPS, but
does not have an agreement to participate in the Medicare program (Patient
Discharge Status Code 02 or Planned Acute Care Hospital Inpatient Readmission
Patient Discharge Status Code 82).
• A critical access hospital (Patient Discharge Status Code 66 or Planned Acute Care
Hospital Readmission Patient Discharge Status Code 94).
C. - Postacute Care Transfers
(Previously Special 10 DRG Rule)
For discharges occurring on or after October 1, 1998, a discharge of a hospital inpatient is
considered to be a transfer for purposes of this part when the patient's discharge is assigned,
as described in 42 CFR 412.4(c), to one of the qualifying Postacute MS-DRGs referenced in
paragraph (D) of this section and the discharge is made under any of the following
circumstances:
• To a hospital or distinct part hospital unit excluded from the inpatient prospective
payment system (under subpart B of 42 CRF 412). Facilities excluded from IPPS are
inpatient rehabilitation facilities and units (Patient Discharge Status Code 62 or
Planned Acute Care Hospital Inpatient Readmission Patient Discharge Status Code
90), long term care hospitals (Patient Discharge Status Code 63 or Planned Acute
Care Hospital Inpatient Readmission Patient Discharge Status Code 91), psychiatric
hospitals and units (Patient Discharge Status Code 65 or Planned Acute Care Hospital
Inpatient Readmission Patient Discharge Status Code 93), children’s hospitals, and
cancer hospitals (Patient Discharge Status Code 05 or Planned Acute Care Hospital
Inpatient Readmission Patient Discharge Status Code 85).
• To a skilled nursing facility (Patient Discharge Status Code 03 or Planned Acute Care
Hospital Inpatient Readmission Patient Discharge Status Code 83).
• To Hospice care at home (Patient Discharge Status Code 50) or Hospice Medical
Facility (Certified) Providing Hospice Level of Care (Patient Discharge Status Code
51).
• To home under a written plan of care for the provision of home health services from a
home health agency and those services begin within 3 days after the date of discharge
(Patient Discharge Status Code 06 or Planned Acute Care Hospital Inpatient
Readmission Patient Discharge Status Code 86).
Specific transfer cases under this paragraph qualify for payment under an alternative
methodology. These include transfer cases in which the patient’s discharge is assigned, as
described in 42 CFR 412.4(f)(2), (f)(5) and (f)(6), to one of the qualifying Special Pay MS-
DRGs referenced in paragraph (D) of this section. For these cases, the transferring hospital
is paid 50 percent of the appropriate inpatient prospective payment rate and 50 percent of the
appropriate transfer payment.
Medicare’s IPPS Postacute care transfer policy requires hospitals to apply the correct Patient
Discharge Status Code to claims where patients receive Home Health (HH) services within 3
days of discharge. This includes the resumption of HH services in place prior to the inpatient
stay.
Medicare’s claims processing system reviews all line item dates of service on HH claims to
determine if the Postacute care transfer payment policy should apply when any HH service
dates are within 3 days after the IPPS discharge date.
In addition to the correct Patient Discharge Status Code, the IPPS hospital may add one of
the following condition codes to the claim, as appropriate, to receive the full MS-DRG
payment:
• Condition Code 42 - used if a patient is discharged to home with HH services,
but the continuing care is not related to the condition or diagnosis for which the
individual received inpatient hospital services.
• Condition Code 43 – used if the continuing care is related, but no HH services
are furnished within 3 days of hospital discharge.
If an acute care hospital submits a bill based on its belief that it is discharging a patient to
home or another setting not included in the Postacute care transfer policy but subsequently
learns that Postacute care was provided, the hospital should submit an adjusted bill.
