Displaced oblique fx shaft of humerus, unsp arm, sequela

This code signifies a past injury involving a complete break across the shaft of the humerus, where the bone fragments are no longer aligned and the fracture line runs diagonally. It indicates that the patient is currently experiencing a complication or residual effect directly attributable to this previously sustained oblique humeral shaft fracture.

Use this code when documenting a patient presenting with a long-term consequence, such as chronic pain, nonunion, malunion, nerve damage, or limited range of motion, that is directly linked to a prior oblique fracture of the humeral shaft. This applies when the initial fracture has healed or is in the process of healing, but its effects persist.

• Always sequence this "S" (sequela) code after the code describing the specific complication or residual condition.
• Ensure documentation clearly links the current condition to the past oblique humeral shaft fracture.
• Verify that the "unspecified arm" aspect is appropriate if laterality is not documented or known.
