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

  • Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
  • The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category S33
  • Ainitial encounter
  • Dsubsequent encounter

Patient EducationClinical

Dislocations

Dislocations are joint injuries that force the ends of your bones out of position. The cause is often a fall or a blow, sometimes from playing a contact sport. You can dislocate your ankles, knees, shoulders, hips, elbows and jaw. You can also dislocate your finger and toe joints.

Questions About S33Overview

Is S33 a billable code?

No. This is a category header that groups the codes for dislocation and sprain of joints and ligaments of lumbar spine and pelvis, and headers cannot be submitted on claims. Claims for dislocation and sprain of joints and ligaments of lumbar spine and pelvis need a more specific code from this category, such as S33.0XXA, S33.0XXD, and S33.0XXS.

Can S33 be reported with a code from M51?

Not as a rule. The Excludes1 note on S33 lists "nontraumatic rupture or displacement of lumbar intervertebral disc NOS (M51.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
