Inpatient Hospital Payments
A. For admissions dated October 1, 2012, and after, the Division of Medicaid reimburses all
hospitals a per stay rate based on All Patient Refined Diagnosis Related Groups (APR-
DRGs). APR-DRGs classify each case based on information contained on the inpatient
Medicaid claim including diagnosis, procedures performed, patient age, patient sex, and
discharge status. The APR-DRG payment is determined by multiplying the APR-DRG
relative weight by the APR-DRG base rate. Medicaid uses a prospective method of
reimbursement and will not make retroactive adjustments except as specified in the Title XIX
Inpatient Hospital Reimbursement Plan.
B. The Division of Medicaid may adjust APR-DRG rates pursuant to changes in federal and/or
state laws or regulations or to obtain budget goals. All Plan changes must be authorized by
the Mississippi Legislature and federal grantor agency,
C. Extraordinarily costly cases in relation to other cases within the same DRG because of the
severity of the illness or complicating conditions may qualify for a cost outlier payment.
This is an add-on payment for expenses that are not predictable by the diagnoses, procedures
performed, and other statistical data captured by the DRG grouper.
1. The additional payment for a cost outlier is determined by calculating the hospital’s
estimated loss. The estimated loss is determined by multiplying the covered charges by
the hospital’s inpatient cost-to-charge ratio minus the DRG base payment. If the
estimated loss is greater than the DRG cost outlier threshold established by the Division
of Medicaid, then the cost outlier payment equals the estimated loss minus the DRG cost
outlier threshold multiplied by the DRG Marginal Cost Percentage. For purposes of this
calculation, the DRG base payment is net of any applicable transfer adjustment.
2. Stays assigned to mental health DRGs are not eligible for cost outlier payments, but may
qualify for a day outlier payment if the mental health stay exceeds the DRG Long Stay
Threshold.
D. Cost-to-Charge Ratio (CCR) Used to Calculate Cost Outlier Payments
1. The Cost-to-Charge Ratios (CCRs) used to calculate cost outlier payments are calculated
for each provider by performing a desk review program developed by the Division of
Medicaid, using the most recent filed cost report. The Division accepts amended original
cost reports if the cost report is submitted prior to the end of the reimbursement period in
which the cost report is used for payment purposes. If the provider’s inpatient cost-to-
charge ratio used to pay cost outlier payments is changed as a result of the amended cost
report, no retroactive adjustments are made to cost outlier payments using the amended
cost-to-charge ratio. After the amended desk review is completed and the thirty (30) day
appeal option has been exhausted the new inpatient cost-to-charge ratio is entered into the
Mississippi Medicaid Management Information System and is in effect from the date of
entry through the end of the current reimbursement period.
2. Out-of-state hospitals are reimbursed under the APR-DRG payment methodology. The
inpatient cost-to-charge ratios (CCRs) used to pay cost outlier payments for each out-of-
state hospital are set using the Federal Register, that applies to the federal fiscal year
beginning October 1of each year, issued prior to the reimbursement period. The inpatient
CCR is calculated using the sum of the statewide average operating urban CCR plus the
statewide average capital CCR for each state.
3. A Mississippi facility which undergoes a change of ownership must notify the Division
of Medicaid in writing of the effective date of the sale. The seller must file a final cost
report with the Division of Medicaid from the date of the last cost report to the effective
date of the sale. The filing of a final cost report may be waived by the Division, if the
cost report is not needed for reimbursement purposes. The new owner must file a cost
report from the date of change of ownership through the end of the Medicare cost report
year end. The new owner must submit provider enrollment information required under
the Division of Medicaid policy.
4. The inpatient cost-to-charge ratio, of the old owner is used to pay cost outlier payments
for the new owner. The new owner’s inpatient cost-to-charge ratio used to pay cost
outlier payments is calculated for the first rate beginning October 1, for which the new
owner’s cost report is available. There are no retroactive adjustments to a new owner’s
inpatient cost-to-charge ratio used to pay cost outlier payments.
5. New Mississippi hospitals beginning operations during a reporting year must file an
initial cost report from the date of certification to the end of the cost report year end.
Each rate year the inpatient cost-to-charge ratio used to pay outlier payments for each
Mississippi hospital is grouped by bed class of facilities and an average inpatient cost-to-
charge ratio is determined for each class. The initial inpatient cost-to-charge ratio used to
pay cost outlier payments to a new hospital will be the average inpatient cost-to-charge
ratio used for the bed class of Mississippi hospitals as of the effective date of the
Medicaid provider agreement until the inpatient cost-to-charge ratio is recalculated based
on the new hospital’s initial cost report. There are no retroactive adjustments to a new
hospital’s inpatient cost-to-charge ratio used to pay cost outlier payments.
E. The Division of Medicaid reimburses for Graduate Medical Education (GME). Payment
schedules and calculations are defined in Attachment 4.19-A of the Medicaid State Plan. The
Division of Medicaid does not reimburse for indirect GME costs. To qualify for GME
payments, Mississippi hospitals must meet the following criteria:
1. Be located in the state of Mississippi.
2. Have accreditation from the Accreditation Council for Graduate Medical Education
(ACGME) or the American Osteopathic Association (AOA) at the beginning of the state
fiscal year in order to qualify for the quarterly payments during the payment year.
3. Have a Medicare approved teaching program for direct GME costs.
4. Be eligible for Medicare GME reimbursement.
5. Render services on the campus of the teaching hospital or at a participating hospital site.
a) The participating site must be listed on the ACGME website.
b) If the participating site uses the teaching hospital’s ACGME accreditation, there must
be a current affiliation agreement in place with the teaching hospital as of July 1st of
the payment year.
c) Only the teaching hospital or the participating hospital site is eligible for GME
reimbursement.
6. Have full-time equivalents (FTEs) reported on Worksheet E-4, line 6, line 15 or line 16
columns 1 and 2 of the most recent Medicare cost report filed with DOM for the calendar
year immediately prior to the beginning of the fiscal year for sponsoring/participating
hospitals.
7. Any hospital which is a newly accredited sponsoring/participating hospital or is within
the five (5) year resident cap building period for the newly accredited
sponsoring/participating hospital must be in operation as of July 1 of the payment year
and must submit:
a) Documentation of accreditation,
b) Medicare’s most recent interim rate letter, and
(1) The number of residents used to calculate medical education payments during cap
building years will be the number of FTEs as reported on the Medicare interim
rate letter.
(2) If the number of FTEs reported on the Medicare interim rate letter does not cover
the entire cost reporting period, the reported FTEs will be annualized and used to
calculate medical education payments,
c) Start date of the GME accredited sponsoring/participating hospital prior to the July 1
calculation of the payments.
8. Has GME eligibility determined each year with the submission of the following annually:
a) Documentation of accreditation,
b) Medicare’s most recent interim rate letter,
c) Number of filled resident positions,
d) Start date of the GME program prior to the July 1 calculation of the payments, and
e) Documentation that the program was in operation as of July 1 of the payment year.
F. Outpatient services provided to a beneficiary by the admitting hospital, or by an entity
wholly owned or operated by the admitting hospital, within the three (3) days prior to an
inpatient hospital admission that are related to the reason for the inpatient hospital stay must
be included in the APR-DRG payment for the inpatient hospital stay. This is referred to as
the three (3) day payment window rule.
1. The inpatient hospital claim must include the following:
a) Diagnostic services provided to a beneficiary within three (3) days prior to and
including the date of an inpatient hospital admission, and
b) Therapeutic (non-diagnostic) services related to an inpatient hospital admission and
provided to a beneficiary within three (3) days prior to and including the date of the
inpatient admission.
2. If outpatient services are provided more than three (3) days prior to admission to a
beneficiary by the admitting hospital, or an entity wholly owned or operated by the
admitting hospital, and the outpatient service dates span to days outside of the three (3)
day window the hospital must:
a) Split bill for the outpatient services provided outside of the three (3) day window on a
claim separate from the inpatient claim, and
b) Include the outpatient services provided that are related to the reason for the inpatient
hospital stay within the three (3) day window on the inpatient hospital claim.
3. Maintenance renal dialysis services are excluded from the three (3) day window payment
rule.
4. Although the Division of Medicaid’s policy is based on Medicare policy, the Division of
Medicaid’s policy applies if there is a difference.
