ICD-10-CM S12.500D: Unspecified Displaced Fracture of Sixth Cervical Vertebra, Subsequent Encounter with Routine Healing

ICD-10-CM code S12.500D designates an unspecified displaced fracture of the sixth cervical vertebra during a subsequent encounter for fracture with routine healing. This active diagnosis concept is classified under the broader parent code S12.500 and appears in Medicare cervical fusion billing documentation. 1 3

Plain-language overview

This diagnosis code represents a subsequent encounter for an unspecified displaced fracture of the sixth cervical vertebra where the fracture is healing routinely. 1

What this code represents

The terminology record classifies S12.500D with the semantic type of Injury or Poisoning and establishes it as an active concept within the ICD-10-CM version 2026 system. 1

S12.500D is a narrower concept under the parent code S12.500, which is the unspecified displaced fracture of the sixth cervical vertebra, and it carries the abbreviation for routine healing. 1

Coding details

Distinct from this routine healing subsequent encounter, other codes in the same category specify initial encounters for closed or open fractures, delayed healing, or nonunion. 4

The code S12.500D is explicitly listed in a Medicare billing and coding article concerning cervical fusion, indicating its appearance in administrative coverage documents. 3

Documentation considerations

Clinical literature indicates that if imaging is positive for vertebral fractures outside the trauma setting, the underlying cause, including osteoporosis or metastatic disease, should be sought out. 2

Clinical context

General vertebral fractures can compromise spinal stability and press on nerves, potentially causing pain or mobility issues, and may result from trauma, osteoporosis, or degenerative conditions. 2 5

What the sources add

While the terminology record provides the exact code definition and hierarchical status, the clinical literature emphasizes evaluating the underlying disease causing the fracture to decrease future risks. 1 2

Coverage and utilization context

A Medicare billing and coding article for cervical fusion explicitly lists S12.500D alongside S12.500G, which denotes a subsequent encounter for fracture with delayed healing. 3 4
