S02.831K Fracture of medial orbital wall, right side, subsequent encounter for fracture with nonunion

Billable ICD-10-CM code, FY2026.

Built from S02.831 with 7th character K (subsequent encounter for fracture with nonunion).

Applies from S02 Fracture of skull and facial bones

• 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
