If you participate in Medicare, you may have
had some of your claims audited. Sometimes,
this results in an overpayment request,
which requires you to refund payment for a
specific claim to Medicare. Our goal at the
AAOS is to ensure that all of our members
are armed with the information necessary to
comply with Medicare policies and avoid
overpayment requests or claims denials. This
article is intended to provide you with a
thorough background of current audit
programs and how to learn more about
successfully complying with Medicare rules.
Medicare Has Increased Audit Programs
In 2010, the President announced three goals for
cutting improper Medicare payments by 2012: reducing
overall payment errors by $50 billion, cutting the
Medicare fee-for-service error rate in half, and
recovering $2 billion in improper payments. To that
end, Medicare has initiated a number of projects
with the intention of reaching those goals. The
Agency is very clear in its statements that these
are not primarily fraud prevention goals. Improper
payments should not be conflated with fraud. All
fraudulent claims are improper payments, but not all
improper payments are fraudulent claims—most
improper payments are due to documentation errors.
Terms You Should Know
MAC:
Medicare Administrative Contractor. The US is split
into fifteen regions for purposes of Medicare claims
administration, though the regions will be
consolidated into ten over the next few years. MACs
are private companies that serve as contractors
performing claims administration for Medicare.
CERT:
Comprehensive Error Rate Testing. The CERT audit
program is designed to monitor the performance of
MACs and to ensure that they are administering
claims properly. CERT audits result in annual
reports of the rate of improper payments made to
hospitals. A high error rate for a particular
procedure on the Part A hospital side may lead to
increased scrutiny of Part B physician claims.
RAC:
Recovery Audit Contractor. A RAC is an independent
medical collection agency that works for Medicare to
recover overpayments from providers. There are
currently four RACs; each of them has an exclusive
geographic jurisdiction. RACs are paid 9-12.5%
contingency fees for the overpayments they recover.
RACs have the ability to analyze claims with payment
dates reaching as far back as October 1, 2007 or 3
years prior to any new RAC initiative.
LCD:
Local Coverage Determination. Much like private
insurers, Medicare has local coverage
determinations. MACs define LCDs for different
procedures. The LCD tells you what Medicare will
cover in its MAC jurisdiction. For example, they
define what constitutes medical necessity for a
specific procedure, and no procedure will be covered
if it is not found to be medically necessary.
Failure to follow the requirements of an LCD will
result in an overpayment, which could be sought
after an audit. If a MAC contains four states, its
LCDs will apply to all four states, unless otherwise
specified.
CAC:
Contractor Advisory Committee. A CAC serves as a
formal mechanism for physicians in each state to be
informed of and participate in the development of an
LCD in an advisory capacity, a mechanism to discuss
and improve administrative policies that are within
MAC discretion, and a forum for information exchange
between MACs and physicians. Every state has a CAC,
so the MACs that contain multiple states will have
multiple CACs commenting on LCDs. Each CAC is
supposed to have an orthopaedic representative.
Current Medicare Audits
RAC Audits
The Recovery Audit Contractor (RAC), program was
created through the Medicare Modernization Act of
2003. It was designed to extract waste from the
Medicare system by identifying and recovering
improper payments paid to healthcare providers. The
RAC program has been successful in reclaiming money
through retrospective review of fee-for-service
claims through a process known as “claw back".
The Centers for Medicare and Medicaid Services (CMS)
began the program in 2005, as a three-year long
demonstration project, which initially focused on
Medicare payments in California, New York, and
Florida and was later expanded to include
Massachusetts and South Carolina. Subsequently,
under the Tax Relief and Health Care Act of 2006,
the permanent RAC program was implemented in all 50
states and also has been expanded to Medicaid in all
50 states.
The RAC program, which divides the U.S. into four
geographic regions, uses contractors to review,
audit, and identify improper Medicare payments in
each of those jurisdictions. Contractors are paid on
a contingency fee basis, receiving a percentage of
the improper payments they collect from providers.
While RAC audits focused on site of care and
upcoding in the past, they are now increasingly
addressing medical necessity. Generally, RAC
auditors may review the last three years of provider
claims, and they may also conduct medical record
reviews.
An adverse opinion from a RAC audit may be appealed.
There are five levels of appeal that need to be
filed within a specific timeline. These levels of
appeal include: Request for Redetermination before
the RAC, Request for Reconsideration with a
Qualified Independent Contractor, Administrative Law
Judge (ALJ) Review, Medicare Appeals Council (MAC)
Review, and Judicial Review. The cost and success of
the appeal process varies at each level.
Recovery Audit Prepayment Review Demonstration
On November 15, CMS announced three new
demonstrations. One of these three year
demonstrations, the Recovery Audit Prepayment Review
Demonstration, was designed to help curb improper
Medicare and Medicaid payments CMS had planned to
implement the three-year demonstration program on
January 1, 2012, but announced in late December that
implementation would be delayed indefinitely. The
AAOS staff anticipate that the program will be
implemented in some form at a later date and staff
continue to monitor developments.
The AAOS staff has been proactively engaged in
fact-finding and advocacy activities related to this
CMS initiative. Shortly after CMS announced this
demonstration, AAOS staff met with lead CMS staff to
discuss implications for AAOS members and their
patients.
As we learned, the demonstration as proposed would
allow Medicare recovery auditors to review claims
after services are provided but before claims are
paid to ensure that the provider complied with all
Medicare payment rules. CMS' goal is to prevent
improper payments before they are made. These
reviews would focus on seven states with high
populations of fraud and error-prone providers (FL,
CA, MI, TX, NY, LA, IL) and four states with high
claims volumes of short inpatient stays (PA, OH, NC,
MO) for a total of 11 states. It is important to
note that while this program is being labeled a
demonstration, it would be implemented in our most
populous states and affect almost 50% of the
Medicare population.
At an Open Door teleconference on December 21, prior
to the decision to delay implementation of the
program, CMS released details of the new
demonstration. As planned, the program would
authorize recovery auditors to review Part A
hospital claims in the 11 approved demonstration
states-after provision of service, but before they
are paid. Initially, the demonstration would focus
on short stay inpatient hospital claims, none of
which involve orthopaedic procedures. CMS staff
cited several recurring problems with claims for
short inpatient hospital stays, including incorrect
coding, patients being admitted from the emergency
department who should have been placed in outpatient
observation, and patients getting surgery on an
elective admission rather than on an outpatient
basis. CMS acknowledged that RACs would be looking
at medical necessity in these prepayment reviews.
The demonstration project, however, would not review
100 percent of claims under the selected DRGs, but
only a limited number. The appeals process for RAC
audits would follow the same procedures as other
appeals.
If the program is successful once implemented, CMS
stated it may authorize reviews on additional DRGs
in the future. CMS also clarified that the
demonstration would not replace MAC prepayment
review. CMS explained, however, that the MACs would
coordinate review areas so providers will not be
reviewed by two different contractors for the same
cases.
While CMS staff disclosed basic operational details
at the Open Door forum, they provided little clarity
regarding the documentation CMS would be seeking to
justify claims. Some of the examples cited by one of
the CMS presenters were criticized during the
question and answer period. Concerned about the
potential future implications for orthopaedic
surgeons, AAOS staff questioned CMS representatives
about the lack of available provider education
materials. Following the criticism that CMS received
in the lead-up to implementation of this program,
the agency decided to delay implementation.
MAC-Generated Prepayment Audits
MACs have always had the authority to audit claims
in order to reduce their CERT error rates. In late
2011, at least two MACs—MAC Jurisdiction 4 and Mac
Jurisdiction 9--initiated audits that target
specific orthopaedic procedures with high error
rates in their jurisdictions.
In the summer of 2011, the contractor for MAC
jurisdiction 9, which includes Florida, Puerto Rico,
and the Virgin Islands, developed an LCD on total
joint replacements. The original draft LCD included
onerous documentation requirements of multiple
12-week non-surgical interventions prior to
authorizing coverage of a total joint replacement.
After receiving comments from the AAOS and the
American Academy of Hip and Knee Surgeons (AAHKS),
the contractor stripped the onerous requirements
from the LCD, making it so that only one
non-surgical intervention needed to fail in order to
meet the requirements of the LCD.
Weeks after the LCD was finalized, the contractor
announced a new prepayment audit of 15 specific DRGs.
Four of them are orthopaedic codes, including that
which covers total joint replacements:
458 -- Spinal fusion except cervical w/spinal curve,
malign, or 9+ fusions w/o CC
460 -- Spinal fusion except cervical w/o MCC
470 -- Major joint replacement or reattachment of
lower extremity w/o MCC
490 -- Back and neck procedures except spinal fusion
w/CC/MCC or disc device/neurostimulator
Under this audit, which only applies in Florida, the
MAC began auditing 100% of Part A hospital claims
related to the 15 DRGs on the list at the beginning
of 2012. Shortly after implementing the audit, the
MAC reduced the rate of claims that it would audit
from 100% to 50% of claims related to DRG 470. The
MAC cited improved documentation as a result of the
orthopaedic community's educational efforts as one
of the reasons for the reduced rate. Under the audit
program, if problems are found with the Part A
claims, then payment will be denied, and the MAC may
then perform a post-payment audit of the Past B
physician services claims related to the problematic
Part A claims. The MAC notes that the review of Part
B claims are most likely to be due to a failure to
support the medical necessity of the procedure.
Physicians must pay close attention to LCDs relating
to the procedures they perform and ensure that
documentation of medical necessity in the hospital
record complies with relevant LCDs.
Around the same time of year, the MAC responsible
for Jurisdiction 4 (Colorado, New Mexico, Texas, and
Wyoming) announced a similar audit with a smaller
number of target DRGs. Two orthopaedic DRGs are
included on this list:
460 -- Spinal fusion except cervical w/o MCC
470 -- Major joint replacement or reattachment of
lower extremity w/o MCC
This audit was scheduled to take place in October
through December of 2011. We have heard very little
provider feedback from this audit, which leads us to
believe that providers are either submitting
documentation and being paid or successfully
appealing claims denials.
Why Are Certain Procedures Targeted by Auditors?
The procedures that are targeted for audits are
those that have shown a high error rate in the MAC
jurisdiction in which they are performed. At least
three MACs have noted high error rates for DRG 470,
total joint replacements. Each of them indicates
that the improper payments are due to a failure to
show medical necessity in the hospital record. This
does not mean that the procedures were not medically
necessary; generally speaking, the problem is not
noting the failure of non-surgical interventions in
the hospital records themselves.
How Can Physicians Properly Document Medical
Necessity?
A specific criterion for proper documentation of
medical necessity depends on the MAC jurisdiction in
which you practice. However, the general consensus
among published LCDs and informal notices generated
by MACs is that failure of conservative treatment
for approximately 12-weeks is necessary to show
medical necessity. While this information may be
present in the physician's office medical record, in
most cases it needs to be documented in the hospital
records, as well. Please consult your local MAC for
specific information. If you are audited and a claim
is denied, the process for appealing the audit is
the same as for any other claims denial.
AAOS Response to Audits
The AAOS Health Care Systems Committee formed a
workgroup to look at developments in Medicare
auditing programs. Workgroup members, Dr. John
Cherf, Dr. Peggy Naas, and Dr. David Halsey, are
preparing an action plan for what the AAOS needs to
provide members in terms of education, materials and
direction. The workgroup is coordinating their
efforts with the AAOS Office of Government
Relations, AAHKS President Carlos Lavernia, MD,
leadership of other orthopaedic subspecialty
organizations, and some state orthopaedic societies
to ensure that our physicians have the information
and tools they need to understand evolving audit
programs and comply with Medicare requirements.
In addition, the AAOS met with CMS officials on
December 27th to discuss the various audit programs
and how the AAOS can work with CMS in order to
ensure that the audit programs are effective,
administered fairly, and that the particulars are
transmitted to our members in a timely fashion. The
AAOS is in the process of scheduling a similar
meeting focused on MAC generated audits. In
addition, the AAOS is working with CMS to develop an
article for the CMS publication MLN Matters.
This document will provide background information on
documentation for total joint replacements and will
be sent to all Medicare fee-for-service providers.
The AAOS also continues to work with state
orthopaedic societies to assist them with their
advocacy efforts as they relate to MACs. One way
that the AAOS is working to offer additional support
on Medicare coverage issues is by developing a
nationwide network of orthopaedic CAC
representatives. This group of orthopaedic surgeons
should be aware of all LCDs being issued in the ten
MACs and can report important information about
trends in Medicare payment policies to the AAOS.
Look for more information about Medicare payment
policies and audit programs at upcoming AAOS
webinars and in future AAOS publications. In the
mean time, please do not hesitate to contact the
AAOS Office of Government Relations at 202-546-4430
or
DC@aaos.org.
