Open wound of abdominal wall without penetration into peritoneal cavity

Version 2021

Not Valid for Submission

ICD-10:S31.1
Short Description:Open wound of abdominal wall w/o penetration into perit cav
Long Description:Open wound of abdominal wall without penetration into peritoneal cavity

Code Classification

  • Injury, poisoning and certain other consequences of external causes (S00–T98)
    • Injuries to the abdomen, lower back, lumbar spine, pelvis and external genitals (S30-S39)
      • Opn wnd abdomen, lower back, pelvis and external genitals (S31)

S31.1 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of open wound of abdominal wall without penetration into peritoneal cavity. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Coding Guidelines

The appropriate 7th character is to be added to each code from block Opn wnd abdomen, lower back, pelvis and external genitals (S31). Use the following options for the aplicable episode of care:

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code S31.1:


Inclusion Terms

Inclusion Terms
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.

Type 2 Excludes

Type 2 Excludes
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.

Information for Patients


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
