S72.325B Nondisplaced transverse fracture of shaft of left femur, initial encounter for open fracture type I or II

ICD-10-CM S72.325B: Nondisplaced transverse fracture of shaft of left femur, initial encounter for open fracture type I or II

ICD-10-CM code S72.325B identifies a nondisplaced transverse fracture of the left femoral shaft during an initial encounter for a type I or II open fracture. The terminology is active and classified as an injury or poisoning concept. Femoral shaft open fractures are severe injuries communicating with the external environment, increasing infection risk. 1 2

Plain-language overview

This diagnosis code represents a specific injury concept for a nondisplaced transverse fracture of the left femur, documented as an initial encounter for an open fracture type I or II. 1

What this code represents

The official label for S72.325B is nondisplaced transverse fracture of shaft of left femur, initial encounter for open fracture type I or II, and the concept is categorized semantically as an injury or poisoning. 1

This code is an active terminology record that holds a parent concept of S72.325, which is the nondisplaced transverse fracture of the shaft of the left femur without the encounter specificity. 1

Coding details

The terminology record for S72.325B includes the published abbreviation nondisp transverse fx shaft of l femr, 7thB, and notes that the concept has narrower related terms in the ICD-10-CM version 2026. 1

A CMS manual lists S72.325B alongside distinct codes for displaced left femur fractures and nondisplaced right femur fractures, confirming its placement within a broader specific fracture classification. 3

Clinical context

Open fractures of the femoral shaft are severe injuries where communication with the outside environment can lead to significant uncontained bleeding and an increased risk of infection. 2

A clinical reference notes that open fractures of the femoral shaft occur in about two percent of all such fractures, and prompt administration of antibiotics and tetanus is imperative to reduce infection risk. 2

Documentation considerations

Clinical literature indicates that the classification of femoral shaft fractures may be descriptive, noting that the location, type, angulation, shortening, comminution, rotation, and displacement are described. 2

What the sources add

While the terminology authority provides the exact code definition and semantic type, the clinical text adds operational context regarding the severity, bleeding, and infection risks associated with open femoral shaft fractures. 1 2
