2025 ICD-10-CM code S28.1

Traumatic amputation (partial) of part of thorax, except breast.

Use secondary codes from Chapter 20 (External causes of morbidity) to specify the cause of injury, unless the T-code already includes it.Additional codes may be needed for any retained foreign body (Z18.-).

Seventh character is required.

Medical necessity for treatment is established by the severity of the injury, the potential for functional impairment, and the risk of complications like infection or hemorrhage. Reattachment or amputation decisions are guided by factors affecting viability and long-term outcomes.

Clinicians should diagnose this condition through patient history, physical examination focusing on nerves and blood vessels in the affected area, and imaging (X-rays, CT, MRI). The Mangled Extremity Severity Score helps determine the viability of reattachment. Treatment includes controlling bleeding, wound cleaning and repair, dressings to prevent infection, pain management (analgesics, NSAIDs), tetanus prophylaxis, and antibiotics if infection develops. Surgical intervention depends on the severity of the damage.

In simple words: Partial traumatic amputation of the chest means part of the chest, not including the breast, was partly severed in an injury, but remains attached by some soft tissue.

Traumatic amputation of part of the thorax refers to the partial removal of thoracic structures, excluding the breast, where the separated parts remain partially connected to the body by soft tissue. This typically occurs due to crush injuries to the chest, such as being squeezed between objects or compressed by a substantial weight.

Example 1: A worker is pinned between two heavy crates, resulting in a partial amputation of the lower rib cage. The ribs are fractured and partially detached, but still connected by muscle and skin tissue., A pedestrian is struck by a vehicle, causing a traumatic partial amputation of the sternum. The sternum is fractured and partially separated from the rib cage, but remains attached by soft tissues., A construction worker falls from scaffolding, leading to a partial traumatic amputation of the upper thoracic wall. Several ribs are fractured and partially separated, but the arm and shoulder blade remain attached.

Documentation should include details of the mechanism of injury, the specific anatomical structures involved, the extent of tissue damage and loss, the status of neurovascular structures, and any associated injuries.
