Diagnostic Related Groups

The ICD-10 code S21.90XS is grouped in the following groups for version MS-DRG V37.0 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 10/01/2020 through 09/30/2020.

  • 604 - TRAUMA TO THE SKIN, SUBCUTANEOUS TISSUE AND BREAST WITH MCC
  • 605 - TRAUMA TO THE SKIN, SUBCUTANEOUS TISSUE AND BREAST WITHOUT MCC

Present on Admission (POA)

S21.90XS is exempt from POA reporting - The Present on Admission (POA) indicator is used for diagnosis codes included in claims involving inpatient admissions to general acute care hospitals. POA indicators must be reported to CMS on each claim to facilitate the grouping of diagnoses codes into the proper Diagnostic Related Groups (DRG). CMS publishes a listing of specific diagnosis codes that are exempt from the POA reporting requirement. Review other POA exempt codes here .

Information for Patients


Chest Injuries and Disorders

The chest is the part of the body between your neck and your abdomen. It includes the ribs and breastbone. Inside your chest are several organs, including the heart, lungs, and esophagus. The pleura, a large thin sheet of tissue, lines the inside of the chest cavity.

Chest injuries and disorders include

  • Heart diseases
  • Lung diseases and collapsed lung
  • Pleural disorders
  • Esophagus disorders
  • Broken ribs
  • Thoracic aortic aneurysms
  • Disorders of the mediastinum, the space between the lungs, breastbone, and spine

Wounds and Injuries

An injury is damage to your body. It is a general term that refers to harm caused by accidents, falls, hits, weapons, and more. In the U.S., millions of people injure themselves every year. These injuries range from minor to life-threatening. Injuries can happen at work or play, indoors or outdoors, driving a car, or walking across the street.

Wounds are injuries that break the skin or other body tissues. They include cuts, scrapes, scratches, and punctured skin. They often happen because of an accident, but surgery, sutures, and stitches also cause wounds. Minor wounds usually aren't serious, but it is important to clean them. Serious and infected wounds may require first aid followed by a visit to your doctor. You should also seek attention if the wound is deep, you cannot close it yourself, you cannot stop the bleeding or get the dirt out, or it does not heal.

Other common types of injuries include

  • Animal bites
  • Bruises
  • Burns
  • Dislocations
  • Electrical injuries
  • Fractures
  • Sprains and strains
