S33: Dislocation and sprain of joints and ligaments of lumbar spine and pelvis

Non-billable headerICD-10-CM

S33 is a non-billable header ICD-10-CM code for dislocation and sprain of joints and ligaments of lumbar spine and pelvis. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.

This code requires a 7th character

The appropriate 7th character is to be added to each code from category S33

A
initial encounter
D
subsequent encounter
S
sequela

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • nontraumatic rupture or displacement of lumbar intervertebral disc NOS (M51.-)
  • obstetric damage to pelvic joints and ligaments (O71.6)

Excludes2: not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • dislocation and sprain of joints and ligaments of hip (S73.-)
  • strain of muscle of lower back and pelvis (S39.01-)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

  • any associated open wound
