Connective tiss and disc stenosis of intervertebral foramina
Connective tissue and disc stenosis of intervertebral foramina
M99.7 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.
M99.70 identifies stenosis of the intervertebral foramina of the head region caused by connective tissue changes or disc encroachment — a biomechanical lesion classified under the M99 block rather than structural spinal stenosis (M48).
M99.71 identifies narrowing of the intervertebral foramina in the cervical spine caused by connective tissue overgrowth or disc pathology — a biomechanical lesion classification used when no more specific structural diagnosis applies.
Stenosis of the thoracic intervertebral foramina caused by connective tissue changes or disc material, classified under biomechanical lesions of the musculoskeletal system.
Connective tissue and disc stenosis of the intervertebral foramina of the lumbar region, classified as a biomechanical lesion under M99 — distinct from pure osseous or subluxation-based foraminal narrowing.
Narrowing of the intervertebral foramina in the sacral region caused by connective tissue changes, disc material, or both — classified as a biomechanical lesion under the M99 category.
Stenosis of the intervertebral foramina in the pelvic region caused by connective tissue changes and/or intervertebral disc pathology, resulting in narrowing that can compress exiting nerve roots at the pelvic spinal level.
Stenosis of the intervertebral foramina of the lower extremity caused by connective tissue and/or disc encroachment, classified as a biomechanical lesion under the M99 category.
M99.77 identifies narrowing of the intervertebral foramina of the upper extremity region caused by connective tissue changes or disc pathology — classified as a biomechanical lesion not elsewhere classified.
Narrowing of the intervertebral foramina of the rib cage caused by connective tissue changes or disc material, classified under biomechanical lesions of the musculoskeletal system.
Stenosis of the intervertebral foramina caused by connective tissue or disc pathology, classified at the abdominal spinal region or any anatomic site that does not map to a more specific M99.7x code.
