Code Classification

  • Diseases of the musculoskeletal system and connective tissue
    (M00–M99)
    • Spondylopathies
      (M45-M49)
      • Other inflammatory spondylopathies
        (M46)

M46.0 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of spinal enthesopathy. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Spinal enthesopathy

Non-specific codes like M46.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for spinal enthesopathy:

  • Use M46.00 for Spinal enthesopathy, site unspecified - BILLABLE CODE

  • Use M46.01 for Spinal enthesopathy, occipito-atlanto-axial region - BILLABLE CODE

  • Use M46.02 for Spinal enthesopathy, cervical region - BILLABLE CODE

  • Use M46.03 for Spinal enthesopathy, cervicothoracic region - BILLABLE CODE

  • Use M46.04 for Spinal enthesopathy, thoracic region - BILLABLE CODE

  • Use M46.05 for Spinal enthesopathy, thoracolumbar region - BILLABLE CODE

  • Use M46.06 for Spinal enthesopathy, lumbar region - BILLABLE CODE

  • Use M46.07 for Spinal enthesopathy, lumbosacral region - BILLABLE CODE

  • Use M46.08 for Spinal enthesopathy, sacral and sacrococcygeal region - BILLABLE CODE

  • Use M46.09 for Spinal enthesopathy, multiple sites in spine - BILLABLE CODE

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code.

Patient Education


Connective Tissue Disorders

Your connective tissue supports many different parts of your body, such as your skin, eyes, and heart. It is like a "cellular glue" that gives your body parts their shape and helps keep them strong. It also helps some of your tissues do their work. It is made of many kinds of proteins. Cartilage and fat are types of connective tissue.

Over 200 disorders that impact connective tissue. There are different types:

  • Genetic disorders, such as Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta
  • Autoimmune disorders, such as lupus and scleroderma
  • Cancers, like some types of soft tissue sarcoma

Each disorder has its own symptoms and needs different treatment.

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.
