ICD-10-CM S96.802D: Unspecified injury of other specified muscles and tendons at ankle and foot level, left foot, subsequent encounter

ICD-10-CM code S96.802D identifies an unspecified injury of other specified muscles and tendons at the ankle and foot level of the left foot during a subsequent encounter. Foot and ankle injuries often have detrimental effects on sport activity and participation. This code is distinct from initial encounter and sequela variations within the same coding category. 4 2 6

Plain-language overview

Foot and ankle injuries are extremely common among athletes and other physically active individuals, and although seldom life-threatening, they often have detrimental effects on sport activity and participation. 2

What this code represents

The ICD-10-CM code S96.802D denotes an unspecified injury of other specified muscles and tendons at the ankle and foot level, left foot, subsequent encounter. 4 6

Coding details

The code S96.802D is listed in the coding tree alongside S96.802A for an initial encounter and S96.802S for sequela, distinguishing the encounter type for the same left foot injury. 6

The coding tree lists S96.802D for the left foot alongside S96.801D for the right foot and S96.809D for the unspecified foot. 6

Documentation considerations

Key elements of the history for ankle and foot disorders include mechanism of injury, onset, location and character of pain, duration of symptoms, and aggravating and alleviating factors. 5

Questions about footwear, exercise frequency, medical history, and occupational history are included in gathering a comprehensive history of presenting illness for ankle and foot overuse disorders. 5

Clinical context

Overuse ankle and foot disorders involve chronic microtrauma to tendons or soft tissues, leading to pain, impaired function, and tissue degeneration. 5

What the sources add

The National Center for Biotechnology Information provides clinical context on ankle sprain incidence and mechanisms, while the Centers for Medicare and Medicaid Services lists the initial encounter variant S96.802A in its coverage database. 1 3

The EVS Explore source provides the exact official display label for S96.802D, and the Unbound Medicine source provides the surrounding code tree structure showing related initial, subsequent, and sequela encounter codes. 4 6
