T84.63 Infection and inflammatory reaction due to internal fixation device of spine

ICD-10-CM T84.63: Infection and inflammatory reaction due to internal fixation device of spine

ICD-10-CM code T84.63 identifies an infection and inflammatory reaction due to an internal fixation device of the spine. The active terminology record classifies this concept as an injury or poisoning. It exists as a specific, child concept beneath the broader parent code for internal fixation device infections. 1 3

Plain-language overview

Code T84.63 describes a health condition where a patient experiences an infection or inflammatory reaction specifically caused by an internal fixation device in their spine. 1

What this code represents

The official display label for T84.63 is infection and inflammatory reaction due to internal fixation device of spine, and the concept is semantically typed as an injury or poisoning. 1

Within the coding hierarchy, T84.63 is a more specific child concept descending directly from the parent code T84.6, which covers infections due to internal fixation devices generally. 1 3

Coding details

The 2026 terminology record indicates that T84.63 is an active code and does not possess any narrower child concepts branching beneath it in the classification system. 1

Code T84.63 exists alongside other anatomical site distinctions, including T84.61 for arm devices and T84.62 for leg devices, distinguishing the spinal location. 3

Clinical context

Clinical literature notes that inflammatory reactions related to spinal devices can mimic deep infection symptoms, and imaging with contrast can help determine which specific devices are affected. 2

Documentation considerations

The official terminology record establishes the specific spinal anatomical site and the presence of an internal fixation device as defining elements of the T84.63 diagnostic concept. 1 3

What the sources add

While the terminology record provides the official code label and hierarchical status, the clinical source adds operational context regarding how such spinal device infections are managed and diagnostically evaluated. 1 2

The terminology record supplies the official classification label and active status, whereas the clinical article details varied surgical and non-surgical management strategies for spinal device infections. 1 2
