Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code M43:

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • congenital spondylolysis and spondylolisthesis Q76.2
  • hemivertebra Q76.3 Q76.4
  • Klippel-Feil syndrome Q76.1
  • lumbarization and sacralization Q76.4
  • platyspondylisis Q76.4
  • spina bifida occulta Q76.0
  • spinal curvature in osteoporosis M80
  • spinal curvature in Paget's disease of bone osteitis deformans M88

Code Classification

  • Diseases of the musculoskeletal system and connective tissue (M00–M99)
    • Deforming dorsopathies (M40-M43)
      • Other deforming dorsopathies (M43)

Information for Patients


Spine Injuries and Disorders

Your backbone, or spine, is made up of 26 bone discs called vertebrae. The vertebrae protect your spinal cord and allow you to stand and bend. A number of problems can change the structure of the spine or damage the vertebrae and surrounding tissue. They include

  • Infections
  • Injuries
  • Tumors
  • Conditions, such as ankylosing spondylitis and scoliosis
  • Bone changes that come with age, such as spinal stenosis and herniated disks

Spinal diseases often cause pain when bone changes put pressure on the spinal cord or nerves. They can also limit movement. Treatments differ by disease, but sometimes they include back braces and surgery.
