• traumatic amputation of hip and thigh (S78.-)

Excludes2 (not included here)

• fracture of lower leg and ankle (S82.-)

• F — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• G — subsequent encounter for closed fracture with delayed healing
• H — subsequent encounter for open fracture type I or II with delayed healing
• J — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
• K — subsequent encounter for closed fracture with nonunion
• M — subsequent encounter for open fracture type I or II with nonunion
• N — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
• P — subsequent encounter for closed fracture with malunion
• Q — subsequent encounter for open fracture type I or II with malunion
• R — subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion
