Diagnostic Related Groups - MS-DRG Mapping

The is diagnosis code is grouped in the following groups for version MS-DRG V40.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2022 through 09/30/2023.

Patient Education

Hernia

A hernia happens when part of an internal organ or tissue bulges through a weak area of muscle. Most hernias are in the abdomen.

There are several types of hernias, including:

• Inguinal, in the groin. This is the the most common type.
• Umbilical, around the belly button
• Incisional, through a scar
• Hiatal, a small opening in the diaphragm that allows the upper part of the stomach to move up into the chest.
• Congenital diaphragmatic, a birth defect that needs surgery

Hernias are common. They can affect men, women, and children. A combination of muscle weakness and straining, such as with heavy lifting, might contribute. Some people are born with weak abdominal muscles and may be more likely to get a hernia.

Treatment is usually surgery to repair the opening in the muscle wall. Untreated hernias can cause pain and health problems.
