S22.040B Wedge compression fracture of fourth thoracic vertebra, initial encounter for open fracture

Billable ICD-10-CM code, FY2026.

Built from S22.040 with 7th character B (initial encounter for open fracture).

Applies from S22 Fracture of rib(s), sternum and thoracic spine

Includes

• fracture of thoracic neural arch
• fracture of thoracic spinous process
• fracture of thoracic transverse process
• fracture of thoracic vertebra
• fracture of thoracic vertebral arch

Excludes1 (never code together)

• transection of thorax (S28.1)

Excludes2 (not included here)

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

Code also

• , if applicable, any associated condition such as:
• injury of intrathoracic organ (S27.-)
• spinal cord injury (S24.0-, S24.1-)
• traumatic hemopneumothorax (S27.2)
• traumatic hemothorax (S27.1-)
• traumatic pneumothorax (S27.0)

7th character note

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

Notes

• A fracture not indicated as displaced or nondisplaced should be coded to displaced
• A fracture not indicated as open or closed should be coded to closed

7th character required

• 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

Risk adjustment (HCC)

• CMS-HCC V28: HCC 401 — Vertebral Fractures without Spinal Cord Injury
• CMS-HCC V22: HCC 169 — Vertebral Fractures without Spinal Cord Injury
• ESRD V24: HCC 169
