PDF296-23A-0310

What is the method for calculating percent of allowed charges (POAC) factors?

POAC factors are based on medicare cost report data and are calculated by dividing adjusted operating expenses by adjusted patient revenues. The department will allow costs for graduate medical education and charity care. Allowable costs for charity care shall not exceed a maximum of two percent of the facility's total allowable costs. A hospital's POAC factor shall not exceed one hundred percent of allowed charges.
Payment rates are calculated by multiplying the POAC factor by the allowed charges.
Amount Paid = (POAC Factor) X (Allowed Charges)
Each hospital will be notified of their revised POAC factor thirty days prior to implementation. Incorrect data or erroneous calculations can be appealed in accordance with WAC 296-23A-0600.

PDF296-23A-0360

What is the method for calculating per diem rates?

Per diem rates are calculated by dividing the total costs for all relevant cases in the historical database by the total number of days. The total number of days is equal to the sum of the number of days for each relevant case. The number of days per case is equal to last date of service minus the first date of service. The department will allocate costs at the detailed revenue code level using medicare cost report data and medicare definitions for allowable costs. The department will allow costs for graduate medical education and charity care. Allowable costs for charity care shall not exceed a maximum of two percent of the facility's total allowable costs.
Payment rates are equal to the applicable per diem rate multiplied by the number of days allowed by the department. The department does not pay for the day of discharge. Payment shall not exceed allowed billed charges.

PDF296-23A-0500

When does a case qualify for high outlier status?

Outlier payments apply only to diagnosis-related-group (DRG) reimbursed cases with unusually high or low costs. Outlier status does not apply to cases paid using a percent of allowed charges (POAC) factor or per diem rates.
A case is considered a high cost outlier if the costs for the case exceed the outlier threshold for the assigned diagnosis-related-group. The costs for a case are determined by multiplying the allowed charges for the case by the hospital specific POAC factor. The threshold used to define a high outlier case is the greater of a dollar threshold of twelve thousand dollars or two standard deviations above the statewide average cost for each DRG paid by the department.
The dollar threshold may be adjusted annually for inflation or other factors as determined by the department. The standard deviations for DRGs will be computed from all relevant cases in the historical database, excluding statistical outliers.

PDF296-23A-0530

How does a case qualify for low outlier status?

To qualify as a low outlier, the allowed charges multiplied by that hospital's percent of allowed charges (POAC) factor must be less than ten percent of the statewide diagnosis-related-group (DRG) rate or five hundred dollars whichever is greater. The standard deviations for DRGs will be computed from all relevant cases in the historical database, excluding statistical outliers.

Under what circumstances will the department pay for interim bills?

The department will deny interim bills which are assigned to diagnosis-related-groups (DRGs) paid per case rates by the department.
If an interim bill is coded as a diagnosis-related-group (DRG) not paid per case rates by the department, then the bill will be paid using the applicable percent of allowed charges (POAC) factor and per diem rates. If a subsequent bill coded as a DRG paid per case rates by the department, for the same injured worker, has a first date of service within seven days of the last date of service of the previous bill, then the bills will be subject to review and adjustment by the department.

PDF296-23A-0560

How does the department define and pay for hospital readmissions?

The department will review hospital readmissions occurring within seven days of discharge and will determine whether the second admission resulted from premature discharge. Payment for services associated with readmission will depend upon the review. For example:
If the second admission is determined unnecessary, reimbursement may be denied.
If the admission was avoidable, the two admissions may be combined and a single diagnosis-related-group (DRG) payment made.
If two different DRG assignments are involved, reimbursement for the appropriate DRG will be based upon review of the case.
Readmissions involving different hospitals will be reviewed by the department and may be paid using the payment method for transfers.

How does the department define a transfer case?

A transfer case is defined as an injured worker's admission to another acute care hospital within seven days of that worker's previous discharge. All bills for transfer cases will be subject to review by the department and payment will be determined based on that analysis. The transferring hospital may qualify for high and low outlier status.
[Statutory Authority: RCW 51.04.020, 51.04.030 and 51.36.080. WSR 97-06-066, § 296-23A-0570, filed 2/28/97, effective 4/1/97.]



PDF296-23A-0575

How does the department pay a transferring hospital for a transfer case?

When the stay at the transferring hospital is a diagnosis-related-group (DRG) paid by the department, and does not qualify as a low outlier, the transferring hospital is paid a graduated per diem rate for each day of care allowed by the department. If the case qualifies as a low cost outlier, the hospital will be paid the graduated per diem amount or low cost outlier payment amount, whichever is lower. The per diem rate is determined by dividing that hospital's rate for the appropriate DRG by that DRG's average length of stay as determined by the department. Payment for the first day of service will be two times the per diem rate. For subsequent allowed days, the basic per diem rate will be paid up to the full DRG payment amount. Unless the case qualifies as a high outlier, payment to the transferring hospital will not exceed the appropriate DRG rate that would have been paid had the injured worker not been transferred to another hospital.

PDF296-23A-0580

How does the department pay the receiving hospital for a transfer case?

The hospital receiving a transfer will be paid according to the department's review of the case. If the receiving hospital's stay is a diagnosis-related-group (DRG) paid by the department, then the hospital will receive the appropriate per case and outlier payments. If the case is not a DRG paid by the department, then the hospital is paid using applicable percent of allowed charges (POAC) factor or per diem rates.

What is the "ambulatory payment classification" (APC) payment system?

The APC outpatient prospective payment system (OPPS) is a reimbursement method that categorizes outpatient visits into groups according to the clinical characteristics, the typical resource use, and the costs associated with the diagnoses and the procedures performed. The groups are called Ambulatory Payment Classifications (APCs). The department uses a modified version of the Centers for Medicare and Medicaid Services' (CMS) Prospective Payment System for Hospital Outpatient Department Services to pay some hospitals for covered outpatient services provided to injured workers. The department will utilize CMS' current outpatient code editor to categorize outpatient visits.
The payment system methodology uses CMS' outpatient prospective payment system's relative weight factor for each APC group and a blend of statewide and hospital-specific rates for each APC.
For a complete description of CMS' Prospective Payment System for Hospital Outpatient Department Services see 42 C.F.R., Chapter IV, Part 419, et al.

How does the department calculate the hospital-specific per APC rate used for paying outpatient services under the outpatient prospective payment system (OPPS)?

(1) OPPS payment rates are calculated with a formula that blends a hospital-specific rate and a statewide rate. Each hospital's historic labor and industries' reimbursement level in combination with the department's statewide payments will determine payment rates.
(2) For the statewide rate, the department:
(a) Determines the total number of APC procedures that the department paid the covered hospitals. The relative weights for all of these APCs are summed.
(b) Determines the total dollar amount the department paid for those APCs.
(c) Determines the total dollar amount the department paid as outlier payments.
(d) Subtracts the total outlier payments in (c) of this subsection from the total dollar amount in (b) of this subsection and then divides the adjusted dollar amount by the APC relative weight total from (a) of this subsection.
(Sum of APC payments - Sum of outlier payments)/Sum of APC relative weights = Statewide rate
(3) For the hospital-specific rate, the department:
(a) Segregates all the APCs for each hospital and totals the relative weights for each hospital.
(b) Determines the total dollar amount the department historically paid each hospital for those APCs.
(c) Determines the total dollar amount the department historically paid each hospital as an outlier payment for those APCs.
(d) Subtracts the total hospital-specific outlier payments in (c) of this subsection from the total hospital-specific APC payments in (b) of this subsection and then divides the hospital's adjusted dollar amount by the hospital-specific APC relative weight total from (a) of this subsection.
(Sum of hospital-specific APC payment - Sum of hospital-specific outlier payments)/Sum of the hospital-specific APC relative weights = Hospital-specific rate
(4) The final per APC rate paid to a hospital is a blended combination of the hospital-specific and statewide rates.

How does the department determine the APC relative weights?

The relative weight for each APC is the current relative weight listed by CMS for the corresponding APC.

How does the department calculate payments for covered outpatient services through the outpatient prospective payment system (OPPS)?

(1) Billed services that are reimbursed by the OPPS are grouped into one or more APCs using the outpatient code editor software.
(2) Additional payment may be made for services classified by CMS as transitional pass-through.
(3) Incidental services are grouped within an APC and are not paid separately.
(4) The OPPS APC payment method uses an APC relative weight for each classification group (APC) and the current hospital-specific blended rate to determine the APC payment for an individual service.
(5) For each additional APC listed on a single claim for services, the payment is calculated with the same formula and then discounted. L&I follows all discounting policies used by CMS for the Medicare Prospective Payment System for Hospital Outpatient Department Services.
(6) APC payment for each APC = (APC relative weight x hospital-specific blended rate)* discount factor (if applicable) x units (if applicable).
(7) The total payment on an APC claim is determined mathematically as follows:
(a) Sum of APC payments for each APC +
(b) Additional payment for each transitional pass-through (if applicable) +
(c) Additional outlier payment (if applicable).
(8) L&I follows all billing policies used by CMS for the Medicare Prospective Payment System for Hospital Outpatient Department Services with respect to:
(a) Billing of units of service;
(b) Outlier claims;
(c) Use of modifiers;
(d) Distinguishing between single and multiple visits during a span of time and reporting a single visit on one claim, but multiple visits with unrelated medical conditions on multiple claims; and
(e) For paying terminated procedures based on services actually provided and documented in the medical record, and properly indicated by the hospital through the CPT codes and modifiers submitted on the claim.

How will excluded outpatient services and hospitals be paid?

Services excluded from APC-payment, if deemed appropriate for reimbursement, will be reimbursed using an alternate outpatient payment method, such as a specific fee schedule and/or using the hospital-specific or the statewide average percent of allowed charges (POAC).
