Disp fx of hook process of hamate bone, unsp wrist, sequela

This code signifies a past, resolved fracture of the hook process of the hamate bone, located in the wrist, where the fracture fragments were not in their normal anatomical alignment at the time of the initial injury. The "sequela" designation indicates that the patient is currently experiencing residual effects or complications directly attributable to this old injury, even though the acute phase of the fracture has passed.

Use this code when documenting a patient presenting with long-term complications such as chronic pain, nonunion, malunion, carpal tunnel syndrome, or tendon irritation, which are directly linked to a previously sustained and displaced fracture of the hamate hook. This code is appropriate when the initial fracture has healed, but its lasting impact on the patient's health is being addressed.

• Always ensure documentation clearly links the current symptoms or condition to the old, displaced hamate hook fracture.
• Do not use this code for acute or active fractures; those require codes from the initial encounter or subsequent encounter categories.
• Specify the laterality (left or right wrist) if known; "unspecified wrist" should only be used when laterality is truly undocumented.
