S32.012K Unstable burst fracture of first lumbar vertebra, subsequent encounter for fracture with nonunion

Billable ICD-10-CM code, FY2026.

Built from S32.012 with 7th character K (subsequent encounter for fracture with nonunion).

Applies from S32 Fracture of lumbar spine and pelvis

Includes

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

Excludes1 (never code together)

• transection of abdomen (S38.3)

Excludes2 (not included here)

• fracture of hip NOS (S72.0-)

Code first

• any associated spinal cord and spinal nerve injury (S34.-)

7th character note

• The appropriate 7th character is to be added to each code from category S32

Notes

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

Applies from S32.0 Fracture of lumbar vertebra

Applicable to

• Fracture of lumbar spine NOS
