What is Diagnostic Related Groups and Why Are They Important for Healthcare Billing?

Diagnostic Related Groups (DRGs) are a system of categorizing hospitalization costs based on the patient’s diagnosis and treatment. DRGs are used by Medicare and some health insurance companies to determine how much to pay for a patient’s hospital stay. DRGs are based on a patient’s primary and secondary diagnoses, other medical conditions, age, sex, and medical procedures. The system categorizes hospital visits by severity of illness, risk of mortality, and treatment difficulty.

How Do DRGs Work?

When a patient is discharged from the hospital, Medicare assigns a DRG based on the main diagnosis that caused the hospitalization, plus up to 24 secondary diagnoses. Every person is different, and two patients with the same condition might need very different types of care. As such, the DRG can also be affected by the patient’s:

  • Primary diagnosis
  • Secondary diagnoses
  • Comorbidities
  • Necessary medical procedures
  • Age
  • Sex

To determine DRG payment amounts, Medicare calculates the average cost of the resources needed to treat people in a particular DRG. This base rate is then adjusted based on various factors, such as the wage index for a given area, the teaching status of the hospital, and the number of uninsured patients the hospital treats. The baseline DRG costs are recalculated annually and released to hospitals, insurers, and other health providers by the Centers for Medicare and Medicaid Services (CMS).

Why Do DRGs Exist?

The DRG system was developed in the late 1960s at Yale University as a way to measure the type and complexity of patients a hospital treats, also known as its case mix. The DRG system was adopted by Medicare in 1983 as a way to control hospital costs and improve efficiency. Before DRGs, Medicare paid hospitals based on their charges, which gave hospitals an incentive to provide more services and stay longer. Under DRGs, Medicare pays hospitals a fixed amount based on the patient’s DRG, which gives hospitals an incentive to provide only the necessary services and discharge patients as soon as possible.

The DRG system is intended to make sure that the care a patient needs is the care they get, while also avoiding unnecessary charges. The DRG system also aims to promote quality of care and patient outcomes by adjusting payments based on the severity and risk of the patient’s condition.

What Is the Impact of DRGs on the Healthcare Industry?

The DRG system has a significant impact on the healthcare industry, as it affects hospitalization costs, reimbursement rates, and patient outcomes. Understanding DRG is important for patients, healthcare providers, and insurance companies, as it influences their decisions and behaviors.

For patients, DRG affects how much they pay for their hospital stay, either directly or indirectly through their insurance plan. Patients may also experience shorter hospital stays and fewer services under the DRG system, which may affect their satisfaction and recovery.

For healthcare providers, DRG affects how much they get paid for providing care to a patient. Providers may also face challenges in coding and documenting the patient’s diagnosis and treatment accurately and completely, as this affects the DRG assignment and payment. Providers may also need to balance the quality and efficiency of care, as they may face penalties for poor outcomes or readmissions.

For insurance companies, DRG affects how much they pay for their beneficiaries’ hospital stays. Insurance companies may also use DRG as a benchmark to negotiate rates with hospitals and monitor their performance. Insurance companies may also offer incentives or disincentives to providers and patients based on the DRG system.
