  • 7th Characters:
    • The appropriate 7th character is to be added to each code from category S21
  • Type 1 Excludes Notes:
    • traumatic amputation (partial) of thorax (S28.1)
  • Code Also:
    • any associated injury, such as:
    • injury of heart (S26.-)
    • injury of intrathoracic organs (S27.-)
    • rib fracture (S22.3-, S22.4-)
    • spinal cord injury (S24.0-, S24.1-)
    • traumatic hemopneumothorax (S27.3)
    • traumatic hemothorax (S27.1)
    • traumatic pneumothorax (S27.0)
    • wound infection

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
  • Chest tube insertion (Medical Encyclopedia)
  • Costochondritis (Medical Encyclopedia)
  • Mediastinal tumor (Medical Encyclopedia)
  • Pectus excavatum (Medical Encyclopedia)
  • Rib fracture - aftercare (Medical Encyclopedia)

Wounds and Injuries

Also called: Traumatic 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
  • Bleeding (Medical Encyclopedia)
  • Crush injury (Medical Encyclopedia)
  • Cuts and puncture wounds (Medical Encyclopedia)
  • Electrical injury (Medical Encyclopedia)
  • Gunshot wounds -- aftercare (Medical Encyclopedia)
  • How wounds heal (Medical Encyclopedia)
  • Laceration - sutures or staples - at home (Medical Encyclopedia)
  • Lacerations - liquid bandage (Medical Encyclopedia)
  • Surgical wound care (Medical Encyclopedia)
  • Surgical wound infection - treatment (Medical Encyclopedia)
  • Wet to dry dressing changes (Medical Encyclopedia)

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.

Index of Diseases and Injuries Definitions

  • And - The word "and" should be interpreted to mean either "and" or "or" when it appears in a title.
  • Code also note - A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
  • Code first - Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • Type 1 Excludes Notes - A type 1 Excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • Type 2 Excludes Notes - A type 2 Excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
  • Includes Notes - This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • Inclusion terms - List of terms is included under some codes. These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • NEC "Not elsewhere classifiable" - This abbreviation in the Alphabetic Index represents "other specified". When a specific code is not available for a condition, the Alphabetic Index directs the coder to the "other specified” code in the Tabular List.
  • NOS "Not otherwise specified" - This abbreviation is the equivalent of unspecified.
  • See - The "see" instruction following a main term in the Alphabetic Index indicates that another term should be referenced. It is necessary to go to the main term referenced with the "see" note to locate the correct code.
  • See Also - A "see also" instruction following a main term in the Alphabetic Index instructs that there is another main term that may also be referenced that may provide additional Alphabetic Index entries that may be useful. It is not necessary to follow the "see also" note when the original main term provides the necessary code.
  • 7th Characters - Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
  • With - The word "with" should be interpreted to mean "associated with" or "due to" when it appears in a code title, the Alphabetic Index, or an instructional note in the Tabular List. The word "with" in the Alphabetic Index is sequenced immediately following the main term, not in alphabetical order.
