S52.04 Fracture of coronoid process of ulna

Non-billable header with 6 child codes.

Applies from S52 Fracture of forearm

Excludes1 (never code together)

• traumatic amputation of forearm (S58.-)

Excludes2 (not included here)

• fracture at wrist and hand level (S62.-)

• D — subsequent encounter for closed fracture with routine healing
• E — subsequent encounter for open fracture type I or II with routine healing
• 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
