Traumatic amputation of ankle and foot (S98) ICD-10-CM

About the S98 Code Range

The ICD-10 code section S98 covers traumatic amputations of the ankle and foot, including various degrees and specific locations of injury. These codes describe complete or partial amputations affecting different toes, the midfoot, and the foot at ankle level, with distinctions by laterality (right, left, or unspecified) and encounter type (initial, subsequent, sequela).

These codes are specifically used to classify traumatic amputations such as "traumatic amputation through the ankle," "traumatic amputation of the great toe," or "partial traumatic amputation of one lesser toe." For example, the code S98.019 corresponds to a complete traumatic amputation of an unspecified foot at the ankle level, often referred to as "traumatic amputation, through ankle." Similarly, traumatic amputation of the greater toe — sometimes described using terms like "traumatic amputation, greater toe" or "open wound of great toe" — is coded under S98.11 and its subcategories. Comprehensive distinctions in these codes help medical coders accurately document the location, completeness, side affected, and the stage of care related to the traumatic amputation, which supports appropriate clinical recording and billing.
