Dislocation and sprain of joints and ligaments of lumbar spine and pelvis (S33) ICD-10-CM
The S33 code range covers dislocation and sprain of joints and ligaments of lumbar spine and pelvis with 84 ICD-10-CM diagnosis codes. 57 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- avulsion of joint or ligament of lumbar spine and pelvis
- laceration of cartilage, joint or ligament of lumbar spine and pelvis
- sprain of cartilage, joint or ligament of lumbar spine and pelvis
- traumatic hemarthrosis of joint or ligament of lumbar spine and pelvis
- traumatic rupture of joint or ligament of lumbar spine and pelvis
- traumatic subluxation of joint or ligament of lumbar spine and pelvis
- traumatic tear of joint or ligament of lumbar spine and pelvis
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 open wound
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.
- nontraumatic rupture or displacement of lumbar intervertebral disc NOS M51
- obstetric damage to pelvic joints and ligaments O71.6
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
- dislocation and sprain of joints and ligaments of hip S73
- strain of muscle of lower back and pelvis S39.01
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 S33
7th Character
Indicates that a seventh character is to be assigned to codes in a subcategory.
- A - initial encounter
- D - subsequent encounter
- S - sequela

About the S33 Code Range
The ICD-10 code section S33 covers dislocations and sprains affecting the joints and ligaments of the lumbar spine and pelvis. These codes identify specific injuries such as traumatic rupture of lumbar intervertebral discs, dislocations of lumbar vertebrae, sacroiliac joints, and the symphysis pubis, as well as sprains of lumbar spine ligaments.
This section includes detailed codes for conditions like traumatic rupture of lumbar intervertebral disc (also known as lumbar disc lesion or traumatic disc rupture), and various dislocations and subluxations at different lumbar vertebral levels (e.g., L1/L2 to L4/L5). It also addresses dislocation and sprain of sacroiliac and sacrococcygeal joints, conditions sometimes referenced as traumatic dislocation of sacroiliac joint or subluxation of sacroiliac joint. The section further includes traumatic rupture of the symphysis pubis, known by synonyms like pubic symphysis separation. Sprain codes specify ligament injuries such as lumbar sprain and tears of specific pelvic ligaments, important for classifying the severity and timing of injury encounters—be it initial, subsequent, or sequela.
Use these codes when documenting or billing for injuries to these lumbar spine and pelvic ligaments or joints, ensuring precise identification of the affected anatomical site and injury status. Understanding the synonyms linked to these codes aids in accurately coding records when terms like lumbar sprain, subluxation of lumbar vertebra, or traumatic dislocation of pelvis are encountered in clinical notes.
