Disp fx of coronoid process of unspecified ulna, sequela

This code signifies a past injury involving a break in the coronoid process of the ulna, where the bone fragments were not in their normal anatomical alignment. The "sequela" designation indicates that this fracture is no longer acute but is causing ongoing problems or conditions.

Apply this code when documentation clearly states a history of a displaced coronoid process fracture of the ulna, and the patient is presenting for treatment of a residual effect or complication directly related to that old injury. This could include chronic pain, limited range of motion, nonunion, malunion, or post-traumatic arthritis stemming from the original fracture.

• Ensure the documentation explicitly states "sequela" or clearly links current symptoms to a past displaced coronoid fracture.
• Confirm the laterality is unspecified if not documented (e.g., "right" or "left").
• Do not use for acute fractures; those require codes from the initial encounter or subsequent encounter categories.
