Osseous and subluxation stenosis of intervertebral foramina
Osseous and subluxation stenosis of intervertebral foramina
M99.6 is a header (parent) code in the ICD-10-CM hierarchy. It is not billable for claim submission. Use one of the billable child codes listed below.
Billable codes in this category
Each of the codes below is billable. Choose the one that most accurately describes the patient's diagnosis.
Narrowing of the intervertebral foramina in the head region caused by bony overgrowth, osseous deposition, or vertebral subluxation that compresses exiting nerve roots at the craniovertebral junction.
M99.61 identifies osseous and subluxation stenosis of the intervertebral foramina specifically in the cervical region — a biomechanical lesion in which bony overgrowth or segmental malalignment narrows the nerve root exit channels of the cervical spine.
Narrowing of the thoracic intervertebral foramina caused by bony overgrowth, osteophyte formation, or vertebral subluxation that mechanically compresses the exiting nerve roots in the thoracic spine.
Narrowing of the lumbar intervertebral foramina caused by bony (osseous) changes and/or vertebral subluxation that compresses the exiting nerve roots at one or more lumbar levels.
M99.64 identifies osseous and subluxation-driven narrowing of the intervertebral foramina specifically at the sacral spinal region, classified as a biomechanical lesion under Chapter 13.
Stenosis of the intervertebral foramina in the pelvic region caused by osseous (bony) changes or subluxation of adjacent spinal or pelvic joint structures, classified as a biomechanical lesion.
Osseous and subluxation stenosis of intervertebral foramina of the lower extremity — narrowing of the nerve root exit channels caused by bony overgrowth or joint subluxation, localized to the lower extremity region per the M99.6 site classification.
M99.67 identifies osseous and subluxation stenosis of the intervertebral foramina affecting the upper extremity region — a biomechanical lesion in which bony overgrowth or vertebral segment subluxation narrows the foraminal opening through which nerve roots exit toward the shoulder, arm, or hand.
M99.68 identifies narrowing of the intervertebral foramina of the rib cage caused by bony (osseous) changes or joint subluxation — a biomechanical lesion classified under Chapter 13 of ICD-10-CM.
M99.69 identifies osseous and subluxation-type stenosis of the intervertebral foramina occurring in the abdomen or in anatomical regions not captured by the more regionally specific M99.6x sibling codes.
