M99.3 Header — not billable

Osseous stenosis of neural canal

Osseous stenosis of neural canal

M99.3 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.

M99.30
Osseous stenosis of neural canal of head region

Bone-driven narrowing of the neural canal at the head region, classified as a biomechanical lesion under the M99 category, distinct from disc-mediated or connective-tissue-mediated stenosis at the same level.

M99.31
Osseous stenosis of neural canal of cervical region

Narrowing of the spinal neural canal in the cervical region caused by bony changes — including osteophytes, hypertrophied facets, or ossified ligaments — that encroach on the canal space.

M99.32
Osseous stenosis of neural canal of thoracic region

Bone-driven narrowing of the spinal canal in the thoracic region that mechanically compresses neural structures, classified under biomechanical lesions not elsewhere classified (M99).

M99.33
Osseous stenosis of neural canal of lumbar region

Bony narrowing of the spinal (neural) canal at the lumbar level, where osseous overgrowth or structural change compresses neural elements within the canal itself — classified as a biomechanical lesion under M99.

M99.34
Osseous stenosis of neural canal of sacral region

Bone-based narrowing of the neural canal at the sacral level, classified under biomechanical lesions of the musculoskeletal system, distinct from disc or connective tissue causes of the same stenosis.

M99.35
Osseous stenosis of neural canal of pelvic region

Osseous stenosis of the neural canal in the pelvic region caused by bony overgrowth or structural changes that narrow the canal and compress neural structures.

M99.36
Osseous stenosis of neural canal of lower extremity

Bone-mediated narrowing of the neural canal affecting the lower extremity region, classified as a biomechanical lesion under the M99 category.

M99.37
Osseous stenosis of neural canal of upper extremity

Bone-driven narrowing of the neural canal in the upper extremity — shoulder girdle, arm, elbow, or forearm region — caused by osseous (bony) encroachment rather than soft-tissue or disc pathology.

M99.38
Osseous stenosis of neural canal of rib cage

M99.38 identifies bone-related narrowing of the neural canal specifically within the rib cage region, classified as a biomechanical lesion not classifiable elsewhere.

M99.39
Osseous stenosis of neural canal of abdomen and oth regions

Osseous stenosis of the neural canal occurring in the abdominal region or other anatomical regions not captured by more specific site-level codes within the M99.3 category.
