Injury record

A fictional adult presents after a fall onto an outstretched left hand. Imaging and the treating clinician document a displaced extra-articular fracture of the distal left radius. The skin is intact, the injury is documented as closed, and no associated ulnar fracture is diagnosed. This encounter provides active treatment.

Treatment report

The physician performs documented closed reduction with manipulation and confirms the result. A short-arm cast is applied to stabilize the treated fracture. The physician documents the post-treatment assessment and instructions and assumes the subsequent fracture care. The exact current treatment entry must be verified from the authorized book.

Included-work review

The same professional encounter includes the initial cast application to the same anatomical site. The proposed charge contains both fracture treatment and a separate cast-application procedure. Supply reporting is a separate question and is not established by merely adding an application code.

Learner record

Abstract the injury separately from the procedure. Do not change the diagnosis to an open fracture because reduction occurred, and do not omit the manipulation documented in the treatment note. The scored question focuses on the first-cast inclusion, while the worksheet asks for the broader lookup route.

Your coding worksheet

Identify the supported injury, side and treatment phase.
Identify the completed treatment and manipulation.
Evaluate the separate initial-cast application proposal.
Find the complete diagnosis and treatment entries in the authorized references.

In your notebook, record the supported facts, your index route, the instructions you checked, and any missing detail that limits your answer.

Compare with the worked explanation

The record describes a closed displaced extra-articular distal left-radius fracture receiving active treatment. Confirm the diagnosis entry and required character in the Tabular List.
The procedure is documented closed treatment with manipulation; injury classification and procedure technique remain separate.
Under NCCI the first cast application is included in that same-site fracture treatment.
Use the documented site and technique for the current treatment lookup. Check any separately permitted supplies through their own instructions rather than assuming the application is separate.
