ICD-10 May Not Offer One-To-One Match

  • Cervical spinal stenosis 
  • Cervical spondylosis with myelopathy

Answer: For ossification of posterior longitudinal ligament in the cervical region, you report code 723.7 (Ossification of posterior longitudinal ligament in cervical region). This code maps to code M67.88 (Other specified disorders of synovium and tendon, other site) in ICD-10 databases. However, a more appropriate ICD-10 code may be M48.8X2 (Other specified spondylopathies, cervical region). 

For cervical spinal stenosis, you report ICD-9 code 723.0 (Spinal stenosis in cervical region). This maps to codes M48.01 (Spinal stenosis, occipito-atlanto-axial region) - M99.71 (Connective tissue and disc stenosis of intervertebral foramina of cervical region) in ICD-10.

You report cervical spondylosis with myelopathy with code 721.1 (Cervical spondylosis with myelopathy). This code maps to M47.011 (Anterior spinal artery compression syndromes, occipito-atlanto-axial region) to M47.13 (Other spondylosis with myelopathy, cervicothoracic region) in ICD-10.
