Billable ICD-10-CM code, FY2026.

Built from S12.120 with 7th character S (sequela).

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

Includes

• 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

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
