Injury of nerves at hip and thigh level (S74)

The ICD-10 code S74 series is specifically used to classify injuries to nerves at the hip and thigh level. It includes codes that identify the particular nerve affected, the leg involved (right, left, or unspecified), and the stage of care such as initial encounter, subsequent encounters, or sequela (late effects).

This group of codes covers injuries to the sciatic nerve (also known as sciatic nerve lesion or injury), the femoral nerve (including traumatic injury or lesions), and the cutaneous sensory nerves like the lateral cutaneous nerve of the thigh. Additionally, S74.8 codes address injuries to other less common nerves at this level, such as the iliolumbar, iliohypogastric, and obturator nerves, which may occur during surgery or trauma. The S74.9 code range is reserved for injuries to unspecified nerves in the hip and thigh region, including cases involving multiple nerves. Coders should select the most accurate code based on the specific nerve affected, the side of the body, and whether it is an initial or follow-up encounter. This detailed classification ensures precise medical documentation and billing for nerve injuries at the hip and thigh area.

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 S71

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.

  • injury of nerves at ankle and foot level S94
  • injury of nerves at lower leg level S84

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 S74

7th Character

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

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