S12.041 Nondisplaced lateral mass fracture of first cervical vertebra

Non-billable ICD-10-CM code.

Applies from S12 Fracture of cervical vertebra and other parts of neck

Includes

• fracture of cervical neural arch
• fracture of cervical spine
• fracture of cervical spinous process
• fracture of cervical transverse process
• fracture of cervical vertebral arch
• fracture of neck

Code first

• any associated cervical spinal cord injury (S14.0, S14.1-)

7th character note

• The appropriate 7th character is to be added to all codes from subcategories S12.0-S12.6

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
