In simple words: The doctor surgically fixes a broken ulna bone in the forearm. This involves an incision to realign the bone and may include using metal plates, screws, or wires to hold it together. A cast or splint is then applied to keep the bone stable while it heals.

This CPT code, 25545, represents the open treatment of a fracture in the shaft of the ulna bone.The procedure involves a surgical incision to access the fracture site, realignment (reduction) of the fractured bone segments, and the application of internal fixation devices (plates, screws, or wires) for stabilization, if necessary.Post-operative steps include wound irrigation, hemostasis, closure of the incision, and application of a splint or cast.

Example 1: A patient presents with a displaced ulnar shaft fracture after a fall.Open reduction and internal fixation with a plate and screws are performed. The post-operative period includes application of a long arm cast., A patient with a comminuted ulnar shaft fracture (multiple bone fragments) undergoes open reduction and internal fixation with multiple screws and possibly bone grafting material. A long-arm cast is applied. , An athlete sustains an ulnar shaft fracture during a sporting event. Open reduction and internal fixation with Kirschner wires are performed. A splint is applied initially, then converted to a cast.

Pre-operative imaging (x-rays), operative report detailing the surgical technique, type and location of internal fixation, post-operative imaging to confirm reduction, and post-operative instructions including pain management and cast care.

** Accurate coding requires detailed documentation of the surgical technique, including the type of internal fixation used.The use of additional codes for bone grafting or other supplemental procedures should be considered if applicable.Always consult the most current CPT coding manual and NCCI edits for accurate coding.
