Note: This Portal page was formerly titled Inpatient & Outpatient Hospital Rates and Inpatient Hospital Weights.
The All Patient Refined Diagnosis Related Group (APR DRG) rates and weights, the Medicare Severity Diagnosis Related Group (MS-DRG) weights and rates, Enhanced Ambulatory Patient Group (EAPG) weights and rates, and outpatient hospital rates per visit are available in the tables on this Portal page. The MS-DRG classification system is still effective for inpatient hospital claims, Medicare crossover claims, and HMO encounters with dates of discharge or “To” DOS before January 1, 2017.

For dates of discharge or "To" dates of service (DOS) on and after January 1, 2017, ForwardHealth groups and prices claims using the APR DRG classification system. The APR DRG rates and weights are updated and published annually. In accordance with federal regulations, Wisconsin provides public notice and an opportunity for written, public comments regarding the proposed hospital reimbursement methodology, inpatient hospital rates, and inpatient hospital weights prior to final approval by the federal Department of Health and Human Services. Current inpatient hospital APR DRG rates and weights and archived inpatient hospital weights and rates are available.
A more detailed description of rate-setting can be found in the Wisconsin Medicaid inpatient and outpatient state plans. Additional APR DRG information, including ForwardHealth updates, training materials, and the APR DRG pricing calculator can be found here.
Note: For dates of discharge or "To" DOS prior to January 1, 2017, ForwardHealth continues to group and price using the Medicare Severity Diagnosis Related Groups (MS-DRG) classification system.
ForwardHealth applies the 3M™ APR DRG grouper and corresponding 3M™ national weights to each APR DRG. These weights reflect the relative resource consumption of each inpatient stay. For example, the average hospitalization with a DRG weight of 1.5 would consume 50% more resources than the average hospitalization with a weight of 1.0; a hospital stay assigned a DRG with a weight of .5 would require half the resources.
ForwardHealth calculates and assigns a payment rate, per inpatient discharge, to each hospital for the rate year. This calculation determines a unique "hospital-specific APR DRG base rate" for the hospital. The hospital-specific APR DRG base rate includes an adjustment for differences in wage and labor levels among rural and metropolitan areas throughout the state. This rate also includes amounts for direct costs of a medical education program.
Payment to a hospital for a member’s hospital stay is calculated by multiplying the hospital’s specific APR DRG base rate by the weight assigned to the DRG into which the stay is classified by the grouper.
To promote members access to acute care hospitals, children’s hospitals, and rehabilitation hospitals throughout Wisconsin, ForwardHealth provides a hospital access payment amount per inpatient discharge. Access payments are intended to reimburse hospital providers based on Wisconsin Medicaid utilization. Therefore, the payment amounts per discharge are not differentiated by hospital based upon acuity or individual hospital cost.
The amount of the hospital access payment per discharge is based upon available funding appropriated in the state budget and aggregate hospital upper payment limit (UPL). The amount of funding is divided by the estimated number of paid inpatient discharges for the state fiscal year. The payment per discharge is in addition to the APR DRG and per diem payments for Wisconsin acute care hospitals, children’s hospitals, and rehabilitation hospitals. Access payments per discharge are only provided until the fee-for-service hospital access payment budget has been expended for the state fiscal year.
A cost outlier payment is made when the cost of providing a service exceeds a pre-determined trim point. Each inpatient hospital claim is tested to determine whether the claim qualifies for a cost outlier payment.
ForwardHealth used the EAPG classification system to calculate pricing for outpatient hospital claims. Using the EAPG classification system, reimbursement for outpatient hospital services is based upon the quantity and type of services provided. The EAPGs ensure that both low- and high-cost services are reimbursed appropriately. The EAPG reimbursement methodology applies to fee-for-service members enrolled in BadgerCare Plus, Wisconsin Medicaid, and the Wisconsin Chronic Disease Program.

On May 16, 2022, the Department of Health Services provided an educational session regarding the RY22 EAPG calculator. A recording of the session can be streamed here.
The session slides can be downloaded here.
Effective January 1, 2017, ForwardHealth applies the 3M EAPG national weights. Prior to that date, ForwardHealth applied state-specific weights. See History page.
The base rate for critical access hospitals is a prospective cost-base rate, established using the most recently available Medicare Cost Report.
The critical access hospital base rate is calculated as follows:
Provider’s Total Cost ÷ Provider’s Total Adjusted Weights = Critical Access Hospital Base Rate
Effective January 1, 2022, the outpatient base rate for psychiatric hospitals is a provider-specific prospective cost-based rate adjusted by a factor of 85.08%.
The base rate for all other hospitals paid under the EAPG reimbursement methodology was calculated by using an inflation factor to increase the prior rate year’s base rate and then adding a Direct Graduate Medical Education (GME) add on where applicable.
Per §7500 of the Wisconsin Hospital Inpatient State Plan (Attachment 4.19-A), approved hospitals may receive a per diem rate for prior authorized brain injury care of Medicaid recipients. The per diem rates are listed in §7900:

Per §7610 of the Wisconsin Hospital Inpatient State Plan (Attachment 4.19-A), an additional payment will be made to a hospital when a long-acting contraceptive (LARC) is provided immediately postpartum to a Medicaid member in an inpatient setting, effective for dates of service on or after January 1, 2017. Costs associated with LARC devices are to be billed separately from the inpatient visit (which is paid via DRG).
- $884.53 is the additional payment for provision of a long-acting contraceptive
