Injury of lumbar and sacral spinal cord and nerves at abdomen, lower back and pelvis level (S34)

The S34 ICD-10 codes are used to classify injuries affecting the lumbar and sacral spinal cord and nerves, located in the abdomen, lower back, and pelvic region. These codes cover a range of spinal cord injuries, including concussions, edema, complete and incomplete lesions, nerve root injuries, and damage to the lumbosacral plexus and sympathetic nerves.

This section further breaks down injuries by specific locations such as lumbar levels (L1-L5), sacral spinal cord, cauda equina, and various nerve roots. For example, S34.01XA identifies an initial encounter for concussion and edema of the lumbar spinal cord, commonly known as spinal cord concussion or contusion. Complete lesions at lumbar levels are indicated by codes like S34.111A, while incomplete lesions, including conditions such as Brown-Séquard syndrome or central cord syndrome, are recorded under codes like S34.121A. Injuries to the nerve roots, lumbosacral plexus, or peripheral and sympathetic nerves at this anatomical region are also coded here, with distinctions between initial encounters, subsequent visits, and sequelae. Using these specific ICD-10 codes ensures accurate identification of the type, location, and phase of spinal cord and nerve injuries in the lower back and pelvis area.

Instructional Notations

Code Also

A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.

  • any associated:
  • fracture of vertebra S22.0 S32.0
  • open wound of abdomen, lower back and pelvis S31
  • transient paralysis R29.5

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to each code from category S34

7th Character

Indicates that a seventh character is to be assigned to codes in a subcategory.

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

  • Code to highest level of lumbar cord injury
  • Injuries to the spinal cord S34.0 S34.1
