S23.0XXD

S23.0XXD — Traumatic rupture of thoracic intervertebral disc, subsequent encounter

Billable / specific codeICD-10-CMPOA exempt

S23.0XXD is a billable, specific ICD-10-CM code for traumatic rupture of thoracic intervertebral disc, subsequent encounter. It is valid for submission on a claim.

7th character "D" — subsequent encounter

The appropriate 7th character is to be added to each code from category S23

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.

rupture or displacement (nontraumatic) of thoracic intervertebral disc NOS (M51.- with fifth character 4)

Excludes1 inherited from the categories above S23.0XXD

These are not written on S23.0XXD, but they bind it: a note on a category applies to every code beneath it. Billing S23.0XXD with anything listed here is a denial.

Written on S23.0 — Traumatic rupture of thoracic intervertebral disc

rupture or displacement (nontraumatic) of thoracic intervertebral disc NOS (M51.- with fifth character 4)

Excludes2 inherited from the categories above S23.0XXD

Also inherited, and the opposite of Excludes1: these conditions are not part of S23.0XXD, but a patient can have both, so you may code both.

Written on S23 — Dislocation and sprain of joints and ligaments of thorax

dislocation, sprain of sternoclavicular joint (S43.2, S43.6)
strain of muscle or tendon of thorax (S29.01-)

Risk adjustment

S23.0XXD does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

S23.0XXD is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
