S33Dislocation and sprain of joints and ligaments of lumbar spine and pelvis

S33 is the ICD-10-CM diagnosis code for dislocation and sprain of joints and ligaments of lumbar spine and pelvis. It belongs to block S30-S39 (injuries to the abdomen, lower back, lumbar spine, pelvis and external genitals) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S33.0 (disc), S33.1 (vertebra), S33.2 (joint), S33.3 (pelvis), S33.4 (pubis), S33.5 (spine), S33.6 (joint), S33.8 (pelvis) and 1 more.

Don't report S33 together with the conditions in its Excludes1 note: nontraumatic rupture or displacement of lumbar intervertebral disc NOS (M51.-) and obstetric damage to pelvic joints and ligaments (O71.6).

The conditions in its Excludes2 note aren't part of S33, but may be coded alongside it if the patient has both: dislocation and sprain of joints and ligaments of hip (S73.-) and strain of muscle of lower back and pelvis (S39.01-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
