Bent bone of unsp ulna, 7thJ

This code describes a malunion of the ulna, specifically a bent or deformed bone, resulting from a severe open fracture (Type IIIA, IIIB, or IIIC) that is now in a delayed healing phase. This indicates that the initial fracture treatment has occurred, but the bone is not healing at the expected rate and has united in an abnormal position.

Use this code for a patient presenting for follow-up care of a previously treated severe open ulnar fracture where imaging confirms a bent bone and the healing process is prolonged beyond the typical timeframe. This applies when the patient is actively receiving care for the delayed union and malunion.

• Requires documentation of an open ulnar fracture (Type IIIA, IIIB, or IIIC) and evidence of delayed healing and malunion.
• The "J" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing and recovery phase.
• Do not use for initial fracture treatment or for nonunion, which has a distinct code.
