- Call to Order/Introductions:
Mr. Metcalf convened the
Worker's Compensation Advisory Council (WCAC) meeting at approximately 10:05
a.m. in accordance with Wisconsin's
open meetings law. WCAC members,
staff and members of the audience introduced themselves.
- Minnesota WC Medical Fee
Schedule: Ms. Lisa Wichterman, Medical Policy Specialist for the Worker's
Compensation Division of the Minnesota Department of Labor and Industry,
appeared at the meeting by telephone conference call to inform the Council
about the Minnesota WC medical fee schedule.
Ms. Wichterman has served in this position for about five years. She previously worked as a WC claims adjuster and worked with
healthcare fee schedules.
The Minnesota WC medical fee schedule uses tables from Medicare A & B.
Medicare A is physician care services.
Medicare B covers charges for hospitals, ASC (ambulatory surgery
centers) and other outpatient healthcare providers.
The fee schedule uses almost only CPT and HCPCS codes.
The fee schedule has relative value units (RVU).
The fee schedule is based on a Medicare formula that uses conversion
factors. There are four conversion
factors used in the Minnesota fee schedule.
The medical-surgical conversion factor amount is $69.87.
The pathology-laboratory conversion factor is set at $41.16.
The physical therapy conversion factor is set at $54.41.
The conversion factor for chiropractic care is $55.58.
The conversion factors used for charges paid by Medicare are much
lower averaging around $30.00.
The CMS tables are based on an elderly population over 65 years old.
The fee schedule looks at every charge in the table.
The CMS tables need to be updated every three years for the fee
schedule. The same table is used for
three years. The most recent table
was updated in October, 2011.The
tables need to be updated to look at new payment policies and keep up to
date on what Medicare is paying for healthcare services.
Many health service charges in the tables do not apply to worker's
There are some healthcare services that RVUs do not cover.
Examples of these are dental services, ambulance services and many
home health care services. These
services are not covered by Medicare and are not listed in the tables.
For these healthcare services not covered by Medicare the Minnesota
fee schedule pays for these services at 85% of the usual and customary
charges. 85% of the billed amount is
to be paid. The Minnesota fee
schedule also pays charges from small hospitals, licensed for 100 beds or
less, at 100% of the amount charged.
An actuary employed by the Department figures out the amount of changes in
charges based on the RVU's. The
actuary uses consumer price index information from the Department of Labor,
Bureau of Labor Statistics. The
provider price index (PPIP) is used to figure the conversion factor for each
year. We start with a 15% reduction
in charges. Annually we look at the
conversion factors and the PPIP. If
the PPIP is up 1.5% for the year we raise the conversion up 1.5%.
In most years the PPIP went up but there was one year where the
conversion went down. There have not
been a lot of complaints from health care providers using the Minnesota fee
schedule. In Minnesota worker's
compensation pays more to health care providers than what is paid for
general group health. The conversion
factor is calculated each year using the PPIP.
The conversion factors are updated every year on October 1st.
In Minnesota there are disputes over medical costs for treatment to injured
employees. Usually these occur on
hospital charges. These disputes can
be resolved by mediators who conduct conferences and look to both sides.
The mediator makes a decision after the conference, which is usually
adopting the amount in the fee schedule.
Examples of some of the disputes include the health care service is
not covered or that it is not related to the injury.
After the decision by the mediator payment is to be made within 30
days. Since there is electronic
billing in Minnesota payment times are faster.
It is unusual if payment is made more than 30 days later.
The Minnesota fee schedule has been in effect 20 to 30 years.
The CMS 2009 table was implemented in 2010.
In Minnesota there are also treatment parameters.
With the treatment parameters if a payer agrees to pay they do not go
back and deny. The treatment
parameters are also used to establish medical necessity for treatment and
promote good health care for injured employees.
When there is a dispute involving the parameters that is about
whether there is a need for departure from the treatment parameters, they
can file a mediation request for a conference with a mediator.
In Minnesota most of the mediators are attorneys and are familiar
with the fee schedule and treatment parameters.
A mediator decision can be appealed to the Office of Administrative
Hearings for the dispute to be heard by an administrative law judge.
It can take 21 days for a mediator to issue a decision.
Once the mediator decision is made a party has 30 days to appeal to
the Office of Administrative Hearings.
It is not known how long it takes the Office of Administrative
Hearings to hold a hearing and issue a decision.
It will take more time for a decision if it is to be heard by a
judge. The number of appeals is not
known but it is probably in the hundreds.
There is no fee schedule in Minnesota for implants.
The charge for implants is based on 85% of the usual and customary
amount. Implants are very expensive.
Minnesota is looking at other ways to set charges for implants.
One method is to use the invoice price plus 25%.
Another way is to use the DRG code for payment if it was done in a
hospital. The implant is part of the
DRG and should be paid for in this manner.
In Minnesota worker's compensation pays more than the Medicare rate.
Minnesota is the only state that pays charges from small hospitals at
100%. Charges from large hospitals
are paid at 85%. For health
insurance, hospitals all have different contracts for payments.
Health insurance payments are based on contracts, not fee schedules.
Worker's compensation payors pay more for services than general health.
The reasons for worker's compensation payors to pay more are that
there is additional paperwork that is required to be completed, ratings for
permanent disability and more time is involved into providing these health
care services. There are no problems
in Minnesota about health care providers not accepting injured employees for
In the Minnesota Worker's Compensation Division, Ms. Wichterman does most of
the work with the medical fee schedule.
She works with an attorney & an actuary.
The mediators are employed by the Department of Industry and Labor.
There are 15 mediators on staff.
Most of the mediators are attorneys who previously worked
representing plaintiffs or defendants.
The mediators work only on worker's compensation cases.
There is information on the Department's website under WC Heath Care
Provider. The website provides links
to CMS tables. The Department does
not have a license to use the CMS tables but there is a link on the website
to access the tables.
In Minnesota physical therapy for work hardening is not part of the fee
schedule. Payment for work hardening
would be at 85% of the usual and customary charges.
If health care charges are not covered by CMS but are covered under
worker's compensation, the charges are paid at 85% of the usual and
The Minnesota Fee Schedule includes bundling edits.
There are some bundling edits for treatment provided to injured
workers. For multiple surgeries, 100%
of the first surgery is paid and 50% of the charge for the second surgery is
paid because this is part of the multiple procedure codes.
$69.87 is the conversion factor for medical and surgical services.
The Medicare conversion factor is $34.00.
Small hospitals with 100 beds or under receive payment at 100%.
Minnesota is now looking at whether this should continue.
Now many of the small hospitals are owned by larger hospitals.
Ms. Wichterman is not certain about the comparison of Medicare rate
reimbursements for Wisconsin and Minnesota.
Wisconsin may have a slightly lower Medicare reimbursement rate but
it is close to what it is in Minnesota.
The Minnesota fee schedule pays at a rate of approximately 200% of
Medicare. Worker's compensation would
usually pay more for health care services compared to group health.
Depending on the contract worker's compensation would pay 10 to 20%
more than group health charges.
In the budget for cost savings on the system in 2010 the actuary did some
work. Ms. Wichterman did not have
numbers on this but it was budget neutral to the state.
Ms. Wichterman had no recollection about there being any outliers in the
system. If there were outliers there
would be a way for this to work through the system.
Shoulder arthroscopies paid at $300 were not noticed.
CMS came up with the RVU's to make sure that they are accurate.
CMS believes that RVU's for physical therapy are too high so there is
a need to make an adjustment. When
new procedures come up CPT and HCPCS codes are added.
The codes can gradually change.
New codes are not added each year.
In Minnesota new codes are added every three years.
If there is no code for a health care procedure the charge defaults
to 85% of usual and customary. The
most current and accurate usual and customary charges available are used.
In Minnesota there are challenges if the right CPT code is not used.
In disputes the mediators look at it.
The mediators would also review the office notes and look at how it
The Minnesota Worker's Compensation Division has a couple of hundred
employees. A medical doctor is on
staff and works two days per week.
The medical doctor is an independent contractor.
The medical doctor is the medical director and he works on the
treatment parameters. He did all of
the research and reviewed all of the studies for the treatment parameters.
At this time he is working on new treatment parameters covering the
use of dorsal column stimulators and pain pumps and drafts of the proposed
treatment parameters covering these are currently available.
The medical director does all the research for the treatment
parameters. The legal department puts
this in legal language for the rules.
There is a committee that works with the medical director on the
treatment parameters. Members of the
committee include doctors, chiropractors, a hospital administrator, a
physical therapist, nurses, and a labor and management representative.
In Minnesota there is no system or process to follow or evaluate treatment
outcomes provided by health care service providers.;
If a worker's compensation claim has been denied and the health insurance
company paid for the medical treatment, the worker's compensation payor
reimburses the health insurance the higher rate.
The worker's compensation payor would reimburse the health insurance
such as Blue Cross who then would pay the health care provider at the higher
rate. The group health insurance pays
the health care provider the amount in the WC medical fee schedule.
If the health care service was not included in the fee schedule it
would fall back to 85% of the usual and customary charge.
The treatment parameters cover treatment provided for injuries to the
cervical spine, thoracic spine, low back, upper extremities RSD, and there
are general guidelines for all injuries.
Good communication helps keep disputes down.
There is good provision of services to injured employees.
There are ways to depart from the treatment provided for in the
treatment parameters. The treatment
parameters help to provide for treatment that is appropriate and prevents
overtreatment and also prevents under-treatment.
Minnesota has a pharmacy fee schedule.
Payments for drugs with the pharmacy fee schedule are based on the
average wholesale price less 12% plus a $3.14 dispensing fee.
The pharmacy fee schedule includes the use of generic drugs.
Physician dispensing is permitted in Minnesota if they get approval
from the Minnesota Medical Board.
Employers can tell employees what pharmacy to get prescriptions from if it
is within 15 miles from their home.
There have been no problems with physician dispensing.
Database Audit Report:
Janet D. Jamieson, Ph.D., project
manager for the audit gave a presentation on the Worker's Compensation
Health Cost Database Audit. 2011
Wisconsin Act 180, Section 30(2) provided statutory authority for the
audit. The audit was required to
be commenced by November 1, 2012, and be completed by June 30th,
2013 so that the standard deviation remains at 1.2 above the mean and
the permanent partial disability maximum benefit rate was not decreased.
Two opinion papers were developed to provide an opinion as to
whether the Department should consider defining economically similar
regions and, if so, a recommendation on the number of regions & how the
regional boundaries should be determined, and an opinion about whether
the current level of 25 occurrences per billing code per region required
by the Department is statistically significant or if it should be
changed. The audit was conducted
in conformance with standard auditing practices and included three major
tasks (1) project administration, (2) developing the audit requirements
and (3) conducting audits of the databases.
The three database companies audited were Rising Medical
Solutions, Inc., Health Systems International, LLC and Fair Health, Inc.
The Department's Hospital Radiology Data Base was also audited.
For the project administration a kickoff meeting was held on November 5th,
2012.There was communication
with the database companies including letters and telephone calls.
The audit project administrator for each database company was
identified as well as the staff responsible for the development of the
certified databases. A detailed
project plan was developed. There
were monthly project status reports & conference calls with the
Department. The project concluded
with providing and presenting the final report.
Requirements for the audit were developed.
The certification documents submitted by each company were
reviewed to identify company specific requirements for the audit.
This led to the development of an audit requirements document for
each company that included performance & technical requirements.
Information & documentation was collected & reviewed from each
database company including the organization, key staff involved in
development of the certified databases and the processes used for
collecting the source data used in developing the certified databases.
Each database company was interviewed to establish a record of
representations of the process used to compile the certified databases.
The source data providers who provided the data included in the
certified databases was validated that included the development of a
source data interview form used to interview two of the major data
contributors for each database company.
In conducting the audits, onsite visits were scheduled.
Onsite interviews were conducted to validate the processes used
to develop the certified databases.
The information from the source data providers was validated.
An examination database for each certified database was collected
& validated by the Department.
The dataset used to develop the certified databases was reviewed.
A random sample of records in the examination database including
records representing all geographical areas and code types were
identified and the information in the selected sample of records was
compared to an image or electronic copy of the billed information.
Rising Medical Solutions, Inc., Health Systems International, LLC and
Fair Health, Inc., cooperated fully in meeting the requirements of the
audit period, the processes the database companies used to develop the
certified databases were validated during the onsite audit interviews
and all procedures and methodology were found to be consistent with
those reported to the Department on their original application for
certification. These database
companies provided a copy of an examination dataset for the period from
July 1 to December 31, 2012 that was verified by the Department.
All three certified database companies provided access during the
onsite visit to their electronic data required to select a random sample
of billing records to validate the data included in the certified
databases. The audit did not
identify any errors in the data records used to create the certified
databases but was able to validate the data in the certified databases.
Each of the three database companies used different approaches to
identify outlier charges in their data.
All three of the companies provided access to information on
their source data providers that was validated as represented on the
information provided in their certification documentation.
Department database certification requirements allow each certified
database company to define their own economically similar regions for
the state. Each of the three
certified database companies identified unique regions for their
database coverage. Rising Medical
Solutions, Inc., sorts data in to four regions of the state.
Health Systems International, LLC defines four regions that
differ from those identified by Rising Medical Solutions, Inc.
Fair Health, Inc. defines eight regions of the state.
Each company identifies the zip codes that are included in each
region and there is some overlap.
A major problem with the current system is that the more delineations
that are used, the more the data is diluted, leading to statistically
Each database company uses a unique methodology for developing their
economically similar regions.
Rising Medical Solutions, Inc. breaks out its data in to four distinct
regions by zip code prefix and the major population centers of Wisconsin
are separated from the geographic areas of the rest of the state.
Health Systems International, LLC identified its regions based
on a 2009 study that Glen Boyle participated in that analyzed statewide
median payment patterns in Wisconsin and tried to develop four groups
that demonstrated similar payment patterns.
Fair Health, Inc. identifies eight economically similar regions
using the same geo zip system that was developed by Ingenix to assign
zip code areas. This zip code
model is based on defining urban and rural areas of the state and areas
that are deemed to be economically similar.
The Department's requirement of at least 25 occurrences per billing code
per region represents a minimum number of occurrences that must be
present in the database or it is not a statistical sample. Determining
the appropriate sample size depends on knowledge of the variation in the
universe of charges for a given medical service within a defined
geographical region. The
methodology for developing an adequate statistical sample is based in
scientific research. Selecting
and identifying a representative sample from a universe of data depends
on understanding the variation within the universe from which the sample
is drawn. Establishing standard
geographical areas for all certified database providers to use might
significantly improve the amount of data available in each geographical
region and the representativeness and validity of the data used by the
Department to adjudicate disputes involving worker's compensation
Suggestions for improving the certification process include the
The Department may
consider identifying the specific economically similar regions of the state
and limiting the number to three or less.
- The Department may
acknowledge that CPT and HCPCS are not different databases and combine the
- The Department may
define the criteria for what is an ambulatory surgical center (ASC) bill.
- The Department may
provide a clear consistent definition of the date range for the certified
- The Department may
consider eliminating the two provider minimum requirement because it should
be much higher if it is to have any value.
- The Department may
allow electronic data submissions or at least email or a simple SFTP site
for transmitting the certified database data.
- The Department may
consider adopting CCI edits and other rules that address payment adjustments
based on modifiers.
