Bent bone of l ulna, 7thF

This code describes a left ulnar shaft fracture that has a bent bone deformity, indicating a malunion or nonunion, and is currently undergoing routine healing. The original injury was a severe open fracture (Type IIIA, IIIB, or IIIC), meaning there was significant soft tissue damage and bone exposure.

Use this code for follow-up encounters where a patient is receiving ongoing care for a previously sustained severe open fracture of the left ulnar shaft that has resulted in a bent bone deformity. This applies when the fracture is healing as expected for its current stage, without complications like delayed healing or infection.

• Ensure documentation specifies "bent bone" or a similar term indicating a malunion/deformity of the ulna.
• Verify the encounter is "subsequent" and the healing status is "routine."
• Confirm the original fracture was an open Type IIIA, IIIB, or IIIC to accurately assign this specific code.
