Traumatic amputation of hip and thigh (S78) ICD-10-CM
The S78 code range covers traumatic amputation of hip and thigh with 82 ICD-10-CM diagnosis codes. 54 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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.
- An amputation not identified as partial or complete should be coded to complete
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.
- traumatic amputation of knee S88.0
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 S78
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela

About the S78 Code Range
The ICD-10 code S78 and its subcodes classify different types of traumatic amputations affecting the hip and thigh area, including complete and partial amputations at various specific locations such as the hip joint or between the hip and knee.
The codes cover traumatic amputations at the hip joint (S78.0), distinguishing between complete amputations like S78.011 (right hip), S78.012 (left hip), and partial ones such as S78.021 (right hip). Similar classification exists for amputations between the hip and knee, for example, complete amputations like S78.111 (right side), and partial ones like S78.121. These codes also specify the encounter stage—initial (7th character A), subsequent (D), or sequela (S), which records the injury’s timeline for clinical and billing accuracy. Synonyms like "traumatic amputation through hip" and "amputated at hip" help clarify the use of these codes. The group ensures precise documentation of trauma-related limb loss at the hip or thigh for healthcare providers and coders.
