Monteggia's fx unsp ulna, 7thJ

This code signifies a Monteggia's fracture, which is a specific type of forearm injury involving a fracture of the ulna (one of the two long bones in the forearm) and a dislocation of the radial head (the top part of the other forearm bone, the radius). This particular code specifies an open fracture (meaning the skin was broken) of types IIIA, IIIB, or IIIC, and indicates that the patient is in a subsequent phase of care due to delayed healing.

Use this code for follow-up encounters where a patient with a previously diagnosed Monteggia's fracture of the ulna (with an open wound of type IIIA, IIIB, or IIIC) is being treated for delayed healing of the fracture. This applies when the initial treatment has been completed, but the bone is not mending at the expected rate.

• Ensure documentation clearly specifies "delayed healing" for this subsequent encounter.
• Verify the original injury was an open Monteggia's fracture of the ulna, specifically type IIIA, IIIB, or IIIC.
• Do not use for initial treatment or for routine follow-up without documented delayed healing.
