ICD-10-CM T84.296D: Other mechanical complication of internal fixation device of vertebrae, subsequent encounter

ICD-10-CM code T84.296D identifies an other mechanical complication involving an internal fixation device of the vertebrae during a subsequent encounter. The terminology record classifies this concept under the semantic type of Injury or Poisoning and lists it as an active code with a parent concept of T84.296. 1 3

Plain-language overview

Code T84.296D describes a subsequent encounter for an other mechanical complication of an internal fixation device of the vertebrae, serving as an active diagnosis concept within the ICD-10-CM terminology. 1

What this code represents

The terminology record assigns T84.296D the preferred name of Other mechanical complication of internal fixation device of vertebrae, subsequent encounter, and classifies its semantic type as Injury or Poisoning. 1 3

Within the code hierarchy, T84.296D is a narrower concept that falls under the parent concept T84.296, which is the other mechanical complication of internal fixation device of vertebrae. 1

Coding details

The code T84.296D is distinct from T84.296A, which represents the initial encounter for the same other mechanical complication of an internal fixation device of the vertebrae. 4

The code T84.296D is distinct from T84.216D, which specifies a breakdown, or mechanical breakdown, of an internal fixation device of the vertebrae during a subsequent encounter. 4

Documentation considerations

The terminology record lists a published abbreviation for T84.296D as Mech compl of internal fixation device of vertebrae, subs, providing an official short-form label for this specific diagnosis. 1

Clinical context

Biomechanical studies measure how spinal fixation devices perform under applied loads, noting that axial forces acting on these devices in vivo are mainly compressive forces. 2

What the sources add

While the terminology record establishes the official code definition and hierarchy for T84.296D, the biomechanical analysis source provides general clinical context regarding the physical forces acting on spinal fixation devices. 1 2

Coverage and utilization context

The supplied sources establish the terminology, hierarchy, and general biomechanical context of spinal fixation devices, but they do not contain payer-specific coverage rules or reimbursement guidelines for code T84.296D. 1 2 4
