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.

About the S70–S79 Code Range
ICD-10-CM codes S70-S79 cover a wide range of injuries specifically affecting the hip and thigh areas, including wounds, fractures, dislocations, sprains, nerve injuries, muscle or tendon damage, crushing injuries, and traumatic amputations.
This group categorizes injuries such as contusions, abrasions, and lacerations of the hip and thigh, as well as more severe trauma like open wounds and amputations of these regions. The codes detail laterality (right, left, unspecified), specify injury types like fractures of various femur parts including the femoral neck, shaft, and condyles, and include subcodes that identify the healing status such as initial encounter, subsequent encounter, or sequela (complications following injury). Notably, synonyms like "Contusion of hip and thigh" or "Traumatic amputation of hip" help clarify coding when conditions are described variably in clinical documentation. Injuries to specific nerves at the hip and thigh, including the sciatic and femoral nerves, and blood vessel injuries, such as those to the femoral artery and vein, are also distinctly coded to aid precise classification. These detailed codes assist coders in accurately documenting the nature, location, and treatment phase of injuries to the hip and thigh, facilitating targeted and effective medical record-keeping.
Within codes S72 and S73, various types of femur fractures and hip joint dislocations are precisely described, including different fracture patterns (transverse, oblique, spiral, comminuted), the condition of being displaced or nondisplaced, and involvement of specific parts of the femur like the head, neck, trochanters, and condyles. Codes for sprains (S73.1) cover ligament and muscle injuries, including strains and ruptures of structures like the iliofemoral ligament and the quadriceps muscle, further refined by side and injury status. Overall, these codes serve to specify all forms of trauma to the hip and thigh to support clinical assessment, treatment planning, and billing.
Questions About This Page
How many codes are in the S70-S79 range?
The S70-S79 range contains 4,214 ICD-10-CM diagnosis codes in FY 2026. 3,546 of them are billable, and the rest are category headers that organize the section.
What conditions does S70-S79 cover?
The range covers injuries to the hip and thigh. The code ranges listed above break it into groups of related conditions, and each one links to its own page with the full code list.
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 S70
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.

Type 1 Excludes
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.
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.
