Medicare-Medicaid Prospective Payment Systems for
Nonhospitalized Patients:
Ambulatory Surgical Center Prospective Payment System
© 2011
Objectives
• Describe the Ambulatory Surgical Center
Prospective Payment System
• Identify the components, adjustments, and
provisions of the ASC PPS
• Recall the payment determination steps for ASC
payment
© 2011
Ambulatory Surgical Centers
• Ambulatory surgical centers (ASCs)
– Provide designated surgical services to
Medicare beneficiaries
– Under Medicare supplementary medical
insurance program (Part B)
– Facility must be Medicare certified
© 2011
Ambulatory Surgical Centers
• Medicare-certified criteria
– Separate entity
– Have own national identifier or supplier number
– Maintain own licensure, accreditation, governance,
professional supervision, administrative functions,
clinical services, record keeping, and financial
accounting systems
– Sole purpose of delivering services in connection with
surgical procedures not requiring inpatient admission
– Meet all requirement of applicable sections of SSA
© 2011
Ambulatory Surgical Centers
• Medicare-certified
– Accept assignment: Medicare payment as
payment in full
• Medicare = 80% total payment
• Beneficiary = 20% total payment
– Payment designed to reimburse for facility
resources (cost)
• Professional payment is excluded
– Physicians reimbursed under Medicare physician fee
schedule
© 2011
Legislation
• Omnibus Budget Reconciliation Act of
1980
– Amended the SSA to create ASC PPS
– ASC List of Covered Procedures
• ASC List
• Implemented in 1982
© 2011
Criteria for ASC Procedures
• Procedures or services commonly performed in the inpatient setting,
but can be safely performed in an ASC
• Limited to procedures requiring a dedicated operating room or suite
and generally require post-operative care
• Limited to procedures that have an operating room time and local,
regional, or general anesthesia duration no greater than 90 minutes and
recovery room time no greater than 4 hours
• Includes procedures not otherwise excluded from Medicare
• Excludes procedures that generally result in extensive blood loss,
require major or prolonged invasion of body cavities, that directly
involve major blood vessels, or that are generally emergency or lifethreatening in nature
• Excludes procedures that are regularly and safely provided in the
physician office setting
© 2011
Site of Service
• With the ASC List Medicare is able to
influence site of service
– Create a motivation for migration from more
expensive inpatient setting to less expensive
outpatient surgery setting
– Without creating a motivation for shifting from
less expensive physician office setting to more
expensive outpatient surgery setting
© 2011
Site of Service (cont.)
• How did they create this motivation?
– Quantitative criteria (beginning in 1987)
• Adds and deletions
– Excluded from list
• Procedure performed in the inpatient setting 20% or less
of the time
• Procedure performed in the physician office setting 50%
or more of the time
• First major revision in 1987
• Next major revision in 1995
• Final major revision in 2004
– Fully revised PPS 2008
© 2011
Legislative History
• BBA 1997
– Proposed APCs for HOPPS
– Also proposed APCs in ASC setting
• BBRA
– 3 year phase in period for APCs in ASC setting
• BIPA
– Delayed implementation to 1/1/02 or after
– Changed phase-in period to 4 years
• NO CHANGE OCCURRED
– Medicare busy with HOPPS and Y2K
© 2011
Legislative History (cont.)
• 2003: Office of the Inspector General released
– Payments for Procedures in Outpatient Departments and
Ambulatory Surgical Centers
• Need for greater similarity in payment rates between hospital
outpatient areas and ASCs
• Disparity in payments cost Medicare $1.1 billion for cases studied
– Recommendations
• Medicare seek authority to update system
• Conduct cost survey
• Update ASC List (over 70 procedures that do not meet criteria still
on list)
© 2011
Legislative History (cont.)
• MMA
– Required the implementation of a new PPS for
ASCs
– Implementation between 1/1/06 and 1/1/08
© 2011
Revised ASC PPS
Effective 1/1/2008
© 2011
ASC PPS
• Utilizes the HCPCS Coding System
– Yearly update for code changes
– Scope of services expanded for CY 2008 (over
700 codes)
• ASC services
• Office-based procedures
© 2011
ASC PPS
• Payment rate is based on APC group relative
weight
– ASC payment is 65% of the OPPS payment
• CY 2008 the conversion factor is $41.401
© 2011
ASC PPS
• Separately payable services (via APCs)
–

–
–
–
Radiology services
Brachytherapy sources
Drugs and biologicals
Implantable devices with OPPS pass-through status
Corneal tissue acquisition
• Integral to surgical service
• Performed on same day as surgery
• Not bundled under OPPS
© 2011
ASC PPS
• Device intensive procedures
– CMS produces a list of device intensive procedures in OPPS
• 50% or more of median cost is due to device
– Under ASC PPS payment methodology is modified for these
procedures
– Allows for equal reimbursement for device regardless of
setting
• Divides payment into 2 portions
– Device portion (not multiplied by CF)
– Procedure portion (multiplied by CF)
© 2011
Adjustment
• Adjustment
– Wage index adjust labor portion of payment
– Based on MSA
– 50% of payment is wage index adjusted
© 2011
Provision
• Multiple and bilateral procedures
– Multiple procedures during same surgical
session
• Highest level Group = 100% payment
• All remaining Groups = 50% payment
– Bilateral procedures
• 150% payment rate for the Group
© 2011
ASC PPS
• Transition period
– Four year transition period for those services that
were on the 2007 ASC List
• Procedures added to the scope of services for 2008 are not
included in the transition (full ASC APC rate in 2008)
• Payment indicators are used to identify procedures that are
subject/not subject to the transition
© 2011
Payment Steps
1. Report service with HCPCS code
2. APC is assigned
3. Multiple/bilateral provision is applied if
applicable
4. Wage index adjusted
5. Payment is made to facility

Objectives
• Outline the history and development of the
Resource-Based Relative Value Scale (RBRVS)
for Physician Payments
• Define key terms
• Describe the structure of the payment system
• Calculate a payment under the RBRVS
© 2011
Resource-Based Relative Value Scale
(RBRVS)
• Federal Payment System for Physicians across
Continuum of Care
• System of Classifying Health Services
• Based on:
– Cost of Furnishing Physician Services in Different
Settings,
– Skills and Training Levels Required to Perform the
Services, and
– Time and Risk Involved
© 2011
History of RBRVS
• Concept of Relative
Value Scale (RVS) Dates
from 1940s
• RVS Represents Worth
of Healthcare Services
• Multiple Views of
“Worth”
– Historical Charges
– Amt. Patients Will Pay
– Physicians’ Assessments
of Worth
– Monetized Societal Good
– Micro-costing from Time
& Motion Studies
– Etc.

Medicare-Medicaid Prospective Payment Systems for
Nonhospitalized Patients: Ambulance Fee Schedule
© 2011
Covered Services
• Medicare Part B provides beneficiary coverage
for ambulance services
– Will provide transport service, only if other means are
inadvisable based on the beneficiary’s medical
condition
– Provided to the nearest facility that is able to provide
services for that patient’s condition
– Transported
• From one hospital to another
• To home
• To an extended care facility
© 2011
History
Two types of ambulance service entities
1. Providers: Associated with a medical facility
such as a hospital, CAH, SNF, or HHA
–
Retrospective reasonable cost payment
– Previous year’s cost-to-charge ratio (CCR)
2. Suppliers: Not associated with a medical
facility
– Reasonable charge payment mechanism
– Fours ways to report ambulance services
© 2011
History (cont.)
• Both types used HCPCS Code Set
– Providers
• A0030–A0999, excluding A0888 (ambulance
codes)
• And codes to report type of mileage
– Suppliers
• A0030-A0999, excluding A0888
• Level I codes 93005 and 93041
• Various other Level II codes
© 2011
Legislation
• BBA of 1997
– Added section 1834(1) to the SSA
– Required the creation of a fee schedule to establish
prospective payment rates for ambulance services
– Devised through negotiated rulemaking (Negotiated
Rulemaking Act of 1990)
• Negotiated Rulemaking Committee on Medicare
Ambulance Services Fee Schedule
© 2011
Legislation (cont.)
• The committee was instructed to:
– Control Medicare expenditures through PPS
– Establish service definitions to link payment to the
type of service
– Consider regional and operational differences
– Consider inflation
– Construct a phase-in period for implementation
– Require providers and supplier to accept Medicare
assignment
– Reimburse providers and suppliers at the lower of FS
or billed charges
© 2011
Legislation (cont.)
• BBA (cont.)
– Established the paramedic intercept service
type (discussed under levels of service)
• BBRA of 1999
– Modified the definition of rural for the
paramedic intercept service type
© 2011
Legislation (cont.)
• BIPA of 2000
– Excluded CAH from the fee schedule payment
methodology when the CAH is the only supplier or
provider of ambulance services within a 35 mile
drive.
• Reasonable cost basis
– Increased payment rates for rural ambulance
mileage
– Modified inflation factor for 7/1/01 to 12/31/01
• Increased 2%
– Eliminated blended payment rate for mileage phasein provision for suppliers
© 2011
Ambulance FS
• Implemented April 1, 2002
• Five year phase-in plan
• Reimbursement is based on the level of
service provided to the beneficiary
– Seven levels of service
