Other and unspecified injuries of abdomen, lower back, pelvis and external genitals (S39)

The S39 ICD-10-CM codes cover a range of other and unspecified injuries affecting the abdomen, lower back, pelvis, and external genitals. These codes are used to classify various types of muscle, fascia, tendon injuries, as well as lacerations, strains, and fractures in these body areas.

This section includes detailed codes for injuries such as unspecified injury of muscle, fascia, and tendon (e.g., S39.001 for the abdomen), as well as more specific diagnoses like strain (S39.011 for abdomen), lacerations (S39.021), and other specified injuries including traumatic disruptions or foreign body injuries. Notably, the codes cover injuries to key areas such as the pelvic muscles and tendons, including pelvic floor muscle tears, and also external genitals with examples like fracture of corpus cavernosum penis (S39.840) or traumatic amputations. Synonyms such as “injury of tendon of abdomen,” “lumbosacral strain,” or “rupture of penis” help clarify common terms medical coders may encounter when assigning the ICD-10 code for these specific injuries. The codes also distinguish initial encounters, subsequent encounters, and sequelae to aid precise reporting of patient care phases. This classification aids in capturing detailed injury data for trauma to these central body regions and reproductive organs.

Instructional Notations

Code Also

A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.

  • any associated open wound S31

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.

  • sprain of joints and ligaments of lumbar spine and pelvis S33

7th Character Note

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.

  • The appropriate 7th character is to be added to each code from category S39

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Priapism

A prolonged painful erection that may lasts hours and is not associated with sexual activity. It is seen in patients with SICKLE CELL ANEMIA, advanced malignancy, spinal trauma; and certain drug treatments.
