This encompasses several metrics designed to classify the resources needed to care for you based on diagnosis, prognosis, and various other factors. Under Medicare's DRG approach, Medicare pays the hospital a predetermined amount under the inpatient prospective payment system (IPS), with the exact amount based on the patient’s DRG or diagnosis.

Before the DRG system was introduced in the 1980s, the hospital would send a bill to Medicare or your insurance company that included charges for every Band-Aid, X-ray, alcohol swab, bedpan, and aspirin, plus a room charge for each day you were hospitalized. The reimbursement methodology has affected the bottom line of many private hospitals, leading some to channel their resources to higher-profit services.

To come up with DRG payment amounts, Medicare calculates the average cost of the resources necessary to treat people in a particular DRG, including the primary diagnosis, secondary diagnoses and comorbidities, necessary medical procedures, age, and gender. For hospitals in Alaska and Hawaii, Medicare even adjusts the non-labor portion of the DRG base payment amount because of the higher cost of living.

Adjustments to the DRG base payment are also made for hospitals that treat a lot of uninsured patients and for teaching hospitals. The baseline DRG costs are recalculated annually and released to hospitals, insurers, and other health providers through the Centers for Medicare and Medicaid Services (CMS).

The DRG payment system encourages hospitals to be more efficient and takes away their incentive to over-treat you. Medicare has rules in place that penalize a hospital in certain circumstances if a patient is re-admitted within 30 days.

This is meant to discourage early discharge, a practice often used to increase the bed occupancy turnover rate. Additionally, in some Dogs, the hospital has to share part of the DRG payment with the rehab facility or home health care provider if it discharges a patient to an inpatient rehab facility or with home health support.

Since those services mean you can be discharged sooner, the hospital is eager to use them so it's more likely to make a profit from the DRG payment. However, Medicare requires the hospital to share part of the DRG payment with the rehab facility or home health care provider to offset the additional costs associated with those services.

Section 1886(d) of the Act specifies that the Secretary shall establish a classification system (referred to as Dogs) for inpatient discharges and adjust payments under the IPS based on appropriate weighting factors assigned to each DRG. Therefore, under the IPS, we pay for inpatient hospital services on a rate per discharge basis that varies according to the DRG to which a beneficiary's stay is assigned.

Congress recognized that it would be necessary to recalculate the DRG relative weights periodically to account for changes in resource consumption. Accordingly, section 1886(d)(4)(C) of the Act requires that the Secretary adjust the DRG classifications and relative weights at least annually.

Currently, cases are classified into Medicare Severity Diagnosis Related Groups (Madras) for payment under the IPS based on the following information reported by the hospital: the principal diagnosis, up to 24 additional diagnoses, and up to 25 procedures performed during the stay. In a few Madras, classification is also based on the age, sex, and discharge status of the patient.

Effective October 1, 2015, the diagnosis and procedure information is reported by the hospital using codes from the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) and the International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS). For additional information on the MS- DRG system, including yearly reviews and changes to the Madras, please view prior Inpatient Prospective Payment System (IPS) proposed and final rules located in the left navigational area of this page.

CMS is hosting a listening session that will describe the Medicare-Severity Diagnosis-Related Group (MSC DRG) Complication and Comorbidity (CC)/Major Complication and Comorbidity (MCC) Comprehensive Analysis discussed in the FY 2020 Inpatient Prospective Payment System (IPS) proposed and final rules. This listening session will include review of the methodology to measure the impact on resource use and will provide an opportunity for CMS to receive public input on this analysis and to address any clarifying questions in order to assist the public in formulating written comments on the current severity level designations for consideration for FY 2021 rule making.

Under the Hopes version of the Madras developed for this requirement, to the extent feasible, the MS- DRG assignment for a given service furnished to an outpatient (billed using a Hopes code) is as similar as possible to the MS- DRG assignment for that service if furnished to an inpatient (billed using an ICD-10-PCS code). The HCPCS-MS- DRG definitions manual and software developed under the requirements of section 15001 of the 21st Century Cures Act (Public Law 114–255).

A diagnosis-related group (DRG) is a patient classification system that standardizes prospective payment to hospitals and encourages cost containment initiatives. In general, a DRG payment covers all charges associated with an inpatient stay from the time of admission to discharge.

Dogs categorize patients with respect to diagnosis, treatment and length of hospital stay. DRG payment is based on the care given to and resources used by a “typical” patient within the group.

Many facility contracts include provisions employing a different methodology of calculating payment in outlier situations. HSA's grouper uses the same DRG case designation categories as Medicare, as defined in the annual Inpatient Prospective Payment System (IPS) Final Rule.

Dogs were first implemented nationwide by the Health Care Financing Administration (CFA) to help control costs for inpatient services billed to Medicare. Providers should refer to the facility contract's Participating Agreement for specific information about HSA's reimbursement methodology and definition for DRG cases.

Note: Charges for non-covered services, such as personal care and convenience items, are the member's responsibility. HSA's DRG Payment schedule for the current year is included in the facility's Participating Agreement.

HSA reserves the right to update the DRG payment schedule at other times during the year as necessary. Diagnosis-related groups (Dogs) were originally developed in the early 1980s as a collaborative project between Robert B. Fetter, PhD, and John D. Thompson, MPH, of Yale University.

The DRG classification is intended to categorize patients by their similar clinical characteristics and costs. The relative weight determines the reimbursement associated with that DRG and reflects the patient's severity of illness and cost of care during hospitalization.

The principal diagnosis is the condition established, after complete evaluation, to be primarily responsible for and the primary focus of the admission. The condition, or at least some signs or symptoms (including test results) of it, must have been present on admission.

It often takes several days to identify the actual cause of signs, symptoms, and abnormal findings that were present on admission. The “focus” of an admission is an important concept, which should guide the selection of a primary diagnosis.

Factors such as severity, risks, complexity of evaluation and care, medications (IV vs. oral) and their risks, diagnostic procedures, number of consultants, and intensity of monitoring (e.g., frequency of vital signs or neuro-checks; nursing time; intensive care) should be considered. Take, for example, a patient admitted for heart failure and pneumonia where the heart failure responded quickly to IV furosemide with no other particular management required, but the pneumonia was prolonged, requiring pulmonary and infectious disease consults and IV administration of potentially nephrotic antibiotics.

As an example, consider the patient admitted with bilateral staphylococcal pneumonia, causing a mild degree of sepsis and respiratory failure. Pursuant to coding rules, as counterintuitive as it may seem to a clinician, sepsis must be assigned as the primary diagnosis.

However, some OR procedures (e.g., endotracheal intubation, transbronchial biopsy or bedside excisional wound debridement) do not have to be performed in an operating room. Some common procedures that are designated as non-OR include esophagogastroscopy, colonoscopy, diagnostic bronchoscopy, and endobronchial biopsy.

If excisional debridement is performed, the DRG changes to 853 (infectious disease with OR procedure with MCC). CCs and CCS are secondary diagnoses that may impact the DRG assignment (see examples in Table).

Is that still considered a type of demand ischemia, or do you recommend something like “non-myocardial infarction (MI) troponin elevation”? The terms chronic myocardial injury, demand ischemia, and “non-MI troponin elevation” are problematic.

Demand ischemia describes an acute supply/demand mismatch without elevation of troponin above the 99th percentile and therefore is not myocardial injury at all. A heated debate arose among my group last week regarding the following scenario: I admit a patient who is extremely ill or moribund and needs a very high level of care (such as pressers, intubation, etc.

), which would normally require a stay longer than two midnight, but in my professional medical opinion I honestly expect them to die within 24 hours. It simply provides that an admission expected to last over two midnight is presumed to be medically necessary if reviewed by a Medicare contractor.

During the first week of May, Anne Boucher and I gave a presentation at the Wei conference in Seattle, featuring the construction and testing of the MS- DRG grouper and the financial impact of the switch from ICD-9 to ICD-10 on MS- DRG mediated hospital reimbursement. Liz McCullough and I had given roughly the same presentation at the CMS Cm meeting in September 2010; Liz repeated it at the AHIMA ICD-10 Summit in April 2011, and I’m giving it again (it gets better every time) at the AHIMA Convention in Salt Lake City this coming October.

Paris Campbell Jersey ISG India © 2016 – 2018 All Rights Reserved. The initial variable used in the classification process is the diagnosis for Dogs and the procedure for APC's.

The APC classification system is designed to explain the amount and type of resources utilized in an outpatient visit. Each APC consists of patients with similar clinical characteristics and resource usage.

APC's include only the facility component of the visit; medical professionals will continue to be paid from a fee schedule based on CPT-4 procedure codes and modifiers. The system encompasses all provider-based ambulatory settings including same day surgery centers (Asks), emergency departments (ED), and clinics, but excludes home visits, nursing home or inpatient admissions.

Examples of surgical APC's include cataract removal, endoscopies, and biopsies. Examples of significant procedure APC's are psychotherapy, CT and MRI scans, radiation therapy, chemotherapy administration, and partial hospitalization.

• Medical APC's consist of encounters with a health care professional for evaluation and management services. The medical APC is determined based on the site of service (clinic or emergency department) and the level of the evaluation and management service (low, mid, or high), as indicated by the evaluation and management CPT-4 code and the diagnosis.

Examples of ancillary APC's are plain film X-rays, electrocardiogram, and cardiac rehabilitation. Effective last January, providers are required to report modifiers, if appropriate, for outpatient services on the UB-92 billing form.

Modifiers are being required for outpatient services in preparation for the introduction of Correct Coding Initiative (CCI) edits. Modifiers will be needed to prevent the CCI edits from rejecting pairs of CPT codes that would not normally be reported on the same UB-92.

Please refer to the 1999 AMA CPT Coding manual for an explanation of the modifiers and those that can be used for hospital outpatient visits. Modifier 74 is used if the procedure is terminated after anesthesia is administered and is paid the full APC amount.

Modifier 25 is applied to an Elm code to indicate that a surgical procedure performed during the visit was a direct result of the evaluation and management service. Another notable coding change includes the ability to bill for critical care (CPT 99291) for the evaluation and management of an unstable critically ill or injured patient who requires the constant attendance of a physician.

Additionally, a new Hopes code will be created for reporting screening services performed in the ED when no medical emergency exists and the patient is referred to a clinic or physician's office for treatment. This screening APC would be paid only if no other emergency services were rendered, and includes any consults.

For example, if you currently bill a month's worth of radiation therapy treatments utilizing the form/through dates on the UB-92 with the number of units indicating the number of treatments given during the period, you will now need a separate line item for each date of service. Multiple clinic visits on the same day for different diagnoses should be submitted on separate claims.

There is also a proposal to modify the UB-92 to identify diagnoses by number and link them to the individual line item being billed, similar to the HCFA-1500. The outpatient claims editor will be expanded to include a subset of the CCI edits.

Unbundled codes will be eliminated from the claim prior to APC assignment and payment. Anesthesia, medical, and surgical supplies, drugs (except chemotherapy), blood, Ions, casts, splints, and donor tissue will also be packaged into the APC.

These services should be continued to be reported so that when the weights are recalculated, the data utilized by CFA will include all the appropriate costs. Multiple surgical procedures performed during the same operative session will be discounted by 50%, just as they currently are under the ASC payment mechanism.

Weights and rates for APC's were based on 1996 Medicare claims and the most recent settled cost report for each facility. However, the proposed system does not provide adjustments for outliers or teaching, rural, disproportionate share, Terra or specialty hospitals.

The co-payment will initially be set at 20% of the 1996 national median APC charge after standardizing for wage variation and then will be updated to 1999. The co-payments are frozen at the 1999 level until the Medicare payment percentage reaches 80% of the APC rate.

Hospitals will be allowed to discount their co-payment amount in an effort to generate competition between providers. Additionally, the discount cannot be less than 20% of the APC payment rate and the co-payment reduction cannot be written off or the deductibles waived.

PPS will also affect hospital operations, particularly the registration, coding, and billing processes and the information systems that support them. Outpatient data access, availability, and quality is problematic for many hospitals due to the volume of visits and information systems limitations.

Additionally, management and reporting processes based on APC's will need to be developed. Compliance issues may result if monitoring and control procedures are not carefully implemented and followed.

The billing challenges include multiple visits on the same day, line item identification of recurring services, clarification of provider-based status, APC grouper errors, lack of pre-fill edit capability, handling of late charges, and reconciliation of billed vs. paid amounts, to name a few. The operational challenges include the ability to distinguish whether multiple visits on the same date of service are related to the same diagnosis or different diagnoses.

Documenting all procedures performed in the ED, clinics, and treatment/procedure rooms, identifying those that are the direct result of a medical visit and selecting the appropriate modifier will require training. The systems challenge include retaining historical data in a readily available format, integrating the APC grouper, enhancing the pre-fill edit process, identifying multiple visits on the same date, splitting out recurring visits by date of service, establishing and maintaining data integrity across system interfaces, standardizing the hospital's CDM across departmental systems, and developing a management reporting capability.

They will also need to review the CDM, super bills, and data entry screens to ensure that appropriate codes are assigned. • Education of administrative, departmental, clinic and medical staffs will be essential to complete the first two prerequisites.

This will require improvements to data access and retention as well as reporting and analysis capabilities. While hospitals have learned to survive and thrive under Dogs, success did not happen overnight.
