Code Classification

  • Injury, poisoning and certain other consequences of external causes
    (S00–T88)
    • Injuries to the thorax
      (S20-S29)
      • Injury of nerves and spinal cord at thorax level
        (S24)

S24.109 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of unspecified injury at unspecified level of thoracic spinal cord. 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.

Unspecified diagnosis codes like S24.109 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding Applicable to Unsp injury at unspecified level of thoracic spinal cord

Non-specific codes like S24.109 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 unsp injury at unspecified level of thoracic spinal cord:

  • Use S24.109A for initial encounter - BILLABLE CODE

  • Use S24.109D for subsequent encounter - BILLABLE CODE

  • Use S24.109S for sequela - BILLABLE CODE

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Closed fracture of T1-T6 level with spinal cord injury
  • Closed fracture of thoracic region with spinal cord injury
  • Fracture of thoracic spine with cord lesion
  • Injury of nerves and spinal cord at thorax level
  • Injury of thoracic spinal cord
  • Injury of thoracic spine
  • Laceration of spinal cord
  • Laceration of thoracic spinal cord
  • Open fracture of T7-T12 level with spinal cord injury
  • Open fracture of thoracic spine with spinal cord injury
  • Thoracic cord injury without spinal bone injury

Coding Guidelines

The appropriate 7th character is to be added to each code from block Injury of nerves and spinal cord at thorax level (S24). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

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. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Patient Education


Spinal Cord Injuries

Your spinal cord is a bundle of nerves that runs down the middle of your back. It carries signals back and forth between your body and your brain. A spinal cord injury disrupts the signals. Spinal cord injuries usually begin with a blow that fractures (breaks) or dislocates your vertebrae, the bone disks that make up your spine. Most injuries don't cut through your spinal cord. Instead, they cause damage when pieces of vertebrae tear into cord tissue or press down on the nerve parts that carry signals.

Spinal cord injuries can be complete or incomplete. With a complete spinal cord injury, the cord can't send signals below the level of the injury. As a result, you are paralyzed below the injury. With an incomplete injury, you have some movement and sensation below the injury.

A spinal cord injury is a medical emergency. Immediate treatment can reduce long-term effects. Treatments may include medicines, braces or traction to stabilize the spine, and surgery. Later treatment usually includes medicines and rehabilitation therapy. Mobility aids and assistive devices may help you to get around and do some daily tasks.
