Powers ratio >1 (insensitive to a vertical distraction injury or posterior dissociation) The key to the diagnosis, in addition to identifying gross disruption of the normal alignment of the atlanto-occipital joint, hinges on using a number of lines on the lateral horizontal shoot-through cervical spine film 1:īasion-dens interval (BDI) >10 mm in adults 3īasion-axial interval (BAI) >12 mm in adults The AO Spine classification of upper cervical injuries is another classification system split into location-specific patterns and then further subdivided according to injury type and presence of neurological signs and/or modifying factors. Type III: fracture extends into the body of the axis. The Traynelis classification describes injuries according to the displacement of the occipital condyles relative to the atlas. Type II: fracture through the base of the dens, at the junction of the odontoid base and the body of C2. Introduction Dens fractures are the most common cervical spine fractures in persons above the age of 65 and account for approximately 5 to 15 of all cervical spine fractures 1 3. Provider unable to clinically determine whether the condition was present at the time of inpatient admission.The tectorial membrane and alar ligaments provide most of the stability to the atlanto-occipital joint, and injury to these ligaments results in instability due to low inherent osseous stability 3. POA Indicators on CMS form 4010A are as follows: Indicatorĭiagnosis was present at time of inpatient admissionĭiagnosis was not present at time of inpatient admissionĭocumentation insufficient to determine if the condition was present at the time of inpatient admission.Ĭlinically undetermined. Pathology The mechanism of injury is variable, and can occur both during flexion or extension, and with or without compression 5. Diagnosis can be made with standard lateral and open-mouth odontoid radiographs. Odontoid process fracture, also known as a peg or dens fracture, occurs where there is a fracture through the odontoid process of C2.
A 'billable code' is detailed enough to be used to specify a medical diagnosis. ICD-10-CM Code for Other displaced dens fracture, initial encounter for closed fracture S12.120A ICD-10 code S12. Topic Podcast Images Summary Odontoid Fractures are relatively common fractures of the C2 (axis) dens that can be seen in low energy falls in elderly patients and high energy traumatic injuries in younger patients. An MRI and/or flexion-extension radiographs are used to evaluate for associated occipitocervical instability. Diagnosis of the fracture is best made with a CT scan. Z87.311 is a billable ICD code used to specify a diagnosis of personal history of (healed) other pathological fracture. Occipital condyle fractures are traumatic injuries that involve articulation between the base of the skull and the cervical spine. This "Present On Admission" (POA) indicator is recorded on CMS form 4010A. Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury. This is the American ICD-10-CM version of S12.11 - other international versions of ICD-10 S12.11 may differ. POA Exempt Code The Center for Medicare & Medicaid Services (CMS) requires medical coders to indicate whether or not a condition was present at the time of admission, in order to properly assign MS-DRG codes. The 2023 edition of ICD-10-CM S12.11 became effective on October 1, 2022.
