Disp fx of coronoid pro of unsp ulna, 7thK

This code describes a displaced fracture of the coronoid process, a small projection on the ulna bone in the forearm, where the specific side (left or right) is not documented. The fracture has failed to heal properly (nonunion) and the patient is receiving follow-up care for this closed injury.

This code is appropriate for subsequent encounters when a patient is being treated for a non-healing, displaced coronoid process fracture of an unspecified ulna. It signifies ongoing management of a closed fracture that has progressed to nonunion.

• Ensure documentation clearly states "nonunion" for the fracture.
• Verify that the encounter is for follow-up care, not initial treatment.
• Only use this code when the laterality of the ulna is not specified in the medical record.
