1、APGs & APCs,Ambulatory Patient Groups & Ambulatory Patient Classifications,What are APCs,Method used to pay hospitals & ambulatory surgery centers for outpatient services using a prospective payment system (PPS) Providers receive fixed payments for individual services Services assigned to various AP

2、C categories,What are APCs,APCs developed from Ambulatory Patient Groups (APGs) Amount & type of resources used in an outpatient visit are grouped in APC categories Services in each APC have similar clinical characteristics, resource use, & cost,What are APCs,Each APC group assigned a weight value a

3、pplied to a conversion factor to yield a hospital payment Conversion factor for 1999 = $51.42 Based on 1996 data from claims paid & cost data,Why APGs Were Developed,To encompass the full range of ambulatory settings i.e. same day surgery units, hospital emergency rooms, outpatient clinics To repres

4、ent ambulatory patients across the entire patient population To differentiate facility & control costs Variation from RBRVS To focus on primacy of hospital care,Current vs. Proposed System,Example: current system Total charges = $5,963 Copay (20%) = $1,193 Total MC allowable = $3,578 MC payment (80%

5、) = $2,862 Example: proposed system with outpatient PPS Total charges = $5,963 Copay (20%) = $1,193 Total MC allowable = $3,578 Actual copay (33%) = ($1193) Total MC payment = $2,385,Current vs. Proposed System,Variance between systems Difference = Proposed (outpatient PPS) - Current= $2,385 - $2,86

6、2= ($477) Increased cost control with proposed system of outpatient PPS,Cost Reductions With Outpatient PPS,Congressionally mandated 5.8% reduction in amounts payable for hospital operating costs 10% reduction in amounts payable for hospital capital costs Scheduled sunset 9/30/98 Extended through 12

7、/31/99,Steps in Developing APGs,Choosing initial classification variable DRGs used major diagnostic categories APCs use procedure categories Partition procedures into set of mutually exclusive procedure groups Inpatient only vs. outpatient,Steps in Developing APGs,Procedures done on ambulatory basis

8、 then assigned to a class Significant procedure Constitutes reason for visit Ancillary service procedure Ordered to assist in diagnosis & treatment,Steps in Developing APGs,Significant Procedure APGs then divided into groups of CPT-4 codes based upon body system associated with the procedure Integum

13、 Surgical Procedures Method = primary classification variable Extent of procedure also important Medical specialty, although classified as a variable, not important Procedures performed by different medical specialties are placed in different APCs,Steps in Developing APGs,Example: Classes of Medical

14、 Procedures Variable Example_ Etiology Trauma, malignancy, etc. Body system Respiratory, digestive, etc. Type of disease Acute, chronic Medical specialty Internal medicine, pediatrics Patient age Pediatric, adult Patient type New, old Complexity Time required, treatment,Steps in Developing APGs,Exam

15、ple: Classes of Medical Procedures Primary variable forming medical APC is diagnosis coded as reason for visit-etiology Visit complexity also important because it influences number of visits + overhead costs,Steps in Developing APGs,Development of ancillary service APGs Laboratory APGs assigned as a

16、 function of different lab departments i.e. hematology, microbiology, toxicology Testing method also used Different methods for performing same test assigned to same APC Also differentiated based on test complexity,Steps in Developing APGs,Ancillary service APGs (cont.) Radiology APCs assigned as a

17、function of equipment used i.e. MRI, CAT, plain film Nuclear medicine separated into diagnostic & therapeutic groups Five radiologic procedures are considered significant procedures because they are interventional & meet definition of Significant Procedure,Steps in Developing APGs,Ancillary service

21、mputed from historical charges Therefore, historical cost basis more likely,Components of APC-Based Outpatient PPS,Ancillary packaging Inclusion of certain ancillary services into APC rate for significant procedure or medical visit Full packaging of all routine low cost procedures is likely,Componen

22、ts of APC-Based Outpatient PPS,Outlier policy Covers atypical cases having higher costs than APC payment amount A stop loss provision Likely to be minimized,Components of APC-Based Outpatient PPS,Discounting When multiple significant procedures are performed or when same ancillary procedure performe

23、d multiple times Window of time for ancillary packaging Can be expanded well beyond the day of a visit,APC Payment System,Patient is described by list of APCs corresponding to each service provided to that patient Contrast to DRGs Multiple APCs can be assigned to a single patient whereas DRGs form a

24、 hierarchy Example: Patient has two procedures performed + chest x-ray + blood test Four APCs are assigned,APC Payment System,Incentives to encourage efficiency & to stanch upcoding are built into system Ancillary packaging Services that contribute to the cost of services in an APC but which are not

25、 paid for separately i.e. chest x-ray packaged with patient pneumonia visit,APC Payment System,Incentives (cont.) Ancillary discounting Multiple procedures 100% of APC with highest payment rate & 50% for all other APCs i.e. multiple significant procedures performed or same procedure performed multip

26、le times Two surgical procedures performed at same time but the cost of prep & use of procedure room is shared by procedures Therefore a discount is applied Terminated procedures,APC Payment System,Use of beneficiary copayment National unadjusted copayment using 1996 median charges + 135 for 1999 Mu

27、ltiplied by 20% Minimum copayment Payment rate x 20%,APC Payment System,Medicare payments Wage adjusted APC payment Pay the lesser of the program percentage determined for each APC or 80%,Example: APC Payment,Breast biopsy: APC 197 Relative weight (RW): 11.94 Conversion factor (CF): $51.42Proposed P
