S98.922A Partial traumatic amputation of left foot, level unspecified, initial encounter

ICD-10-CM S98.922A: Partial traumatic amputation of left foot, level unspecified, initial encounter

ICD-10-CM code S98.922A identifies a partial traumatic amputation of the left foot at an unspecified level during the initial encounter. It is an active diagnosis concept classified as an injury or poisoning, with a parent code that omits the encounter extension. General sources discuss functional impacts and coverage variability for amputations. 1 2 3

Plain-language overview

This diagnosis code represents a partial traumatic amputation of the left foot where the specific anatomical level is not specified, captured during the initial encounter for this injury. 1

What this code represents

The terminology record assigns this concept the semantic type of Injury or Poisoning and maintains its record status as active within the 2026 version of ICD-10-CM. 1

S98.922A is a narrower concept derived from the parent code S98.922, which describes the identical partial traumatic amputation of the left foot without the initial encounter designation. 1

Coding details

The published abbreviation for this specific diagnosis is partial traumatic amputation of left foot, level unsp, init, serving as a shortened reference within the terminology system. 1

Documentation considerations

The terminology record specifies the exact descriptive title as partial traumatic amputation of left foot, level unspecified, initial encounter, providing the precise text for clinical alignment. 1

Clinical context

Research indicates that altered body biomechanics resulting from an amputation contribute to substantial functional limitations, influencing physical activity levels and the completion of activities of daily living. 2

Coverage and utilization context

Therapies for amputations are often covered fully or partially by Medicare, Medicaid, and private health insurance plans, though prosthetic limb costs vary depending on the type of amputation and health care coverage. 3

What the sources add

While the terminology record defines the code structure, clinical research highlights that different partial foot amputation levels negatively affect gait parameters, and public health sources detail variable insurance coverage for recovery therapies. 1 2 3

Questions to verify

The supplied sources do not establish the specific clinical causes of traumatic foot amputations, nor do they provide detailed treatment protocols or prognosis outcomes for this particular diagnosis code. 1 2 3
