What cannot be coded together with S22.029A?

S22.029A

S22.029A — Unspecified fracture of second thoracic vertebra, initial encounter for closed fracture

Billable / specific codeICD-10-CM

S22.029A is a billable, specific ICD-10-CM code for unspecified fracture of second thoracic vertebra, initial encounter for closed fracture. It is valid for submission on a claim.

7th character "A" — initial encounter for closed fracture

The appropriate 7th character is to be added to each code from category S22

A: initial encounter for closed fracture
B: initial encounter for open fracture
D: subsequent encounter for fracture with routine healing
G: subsequent encounter for fracture with delayed healing
K: subsequent encounter for fracture with nonunion
S: sequela

Excludes1 inherited from the categories above S22.029A

These are not written on S22.029A, but they bind it: a note on a category applies to every code beneath it. Billing S22.029A with anything listed here is a denial.

Written on S22 — Fracture of rib(s), sternum and thoracic spine

transection of thorax (S28.1)

Excludes2 inherited from the categories above S22.029A

Also inherited, and the opposite of Excludes1: these conditions are not part of S22.029A, but a patient can have both, so you may code both.

Written on S22 — Fracture of rib(s), sternum and thoracic spine

fracture of clavicle (S42.0-)
fracture of scapula (S42.1-)

Other codes that can never be billed with S22.029A

These codes carry an Excludes1 note pointing at S22.029A. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading S22.029A alone.

M48.5Collapsed vertebra, not elsewhere classified
M84.3Stress fracture
M84.4Pathological fracture, not elsewhere classified

Risk adjustment

S22.029A risk-adjusts. Under the CMS-HCC V28 model it maps to this category:

HCC 401 Vertebral Fractures without Spinal Cord Injury0.522 RAF

Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
