ICD-10-CM Code For Dislocation And Sprain Of Joints And Ligaments At Neck Level: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group S13 includes dislocations and sprains of joints and ligaments at the neck level, such as cervical joint dislocation, cervical ligament sprain, and related soft tissue injuries. These ICD-10-CM diagnosis codes are used to document acute traumatic injuries to the cervical spine, capturing injury location, laterality when applicable, and associated complexity. Accurate coding within the ICD-10-CM S13 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

ICD-10-CM S13: Dislocation and Sprain Of Joints And Ligaments At Neck Level Overview

This group covers dislocations and sprains affecting the cervical spine, including injuries to joints and supporting ligaments at the neck level. These diagnoses target the musculoskeletal and nervous systems by identifying instability, soft tissue damage, or joint displacement in the cervical region. Accurate coding is important to reflect clinical severity and to support correct reimbursement for services related to diagnosis, imaging, and treatment.

When to Use

Use a code from this group when the clinical record documents a dislocation or sprain of cervical joints or ligaments due to trauma or injury. Select codes that reflect the exact cervical level, laterality when specified, and whether the encounter is initial, subsequent, or for sequelae.

Typical Clinical Scenarios

A middle-aged motor vehicle crash victim arrives to the emergency department with severe neck pain, limited range of motion, and palpable step-off after a high-speed rear-end collision. Imaging (CT or cervical spine x-rays) demonstrates an acute unilateral facet dislocation at C5-C6 without neurological deficit; the presentation is acute and requires urgent immobilization and orthopedic evaluation, so an initial encounter code for a cervical dislocation is assigned. Typical codes: S13.101A, S13.110A
An adult who sustained a whiplash injury several weeks earlier continues to have persistent neck pain, episodes of instability, and limited activity despite conservative management; this patient is seen in outpatient follow-up for ongoing symptoms. Because the visit documents a sequela of the prior traumatic cervical ligamentous injury with ongoing signs, a subsequent encounter or sequela code for sprain/dislocation is used to reflect the continuing condition. Typical codes: S13.0XXD, S13.4XXD
An elderly patient presents with new radicular arm weakness and numbness two weeks after an initial cervical sprain that was treated conservatively; imaging now shows a subluxation with compression of a nerve root and the visit documents complications of the prior neck injury requiring surgical consultation. A code indicating a laterality-specific cervical dislocation or sprain with subsequent encounter or complication coding is assigned to capture the current complication of the original neck injury. Typical codes: S13.121D, S13.131D
