Nondisp fx of body of hamate bone, unsp wrs, init for opn fx

This diagnosis code signifies a break in the main part of the hamate bone, a carpal bone in the wrist, that has not shifted from its normal anatomical position. The injury affects an unspecified wrist and is an open fracture, meaning the skin and soft tissues overlying the fracture site have been compromised. This code is used for the initial treatment of such an injury.

This code is appropriate for documenting the initial encounter for a patient presenting with an open, non-displaced fracture of the hamate bone's body, where the specific wrist (left or right) is not documented. This would typically be used in emergency department settings or during the initial surgical repair.

• Ensure documentation clearly states "nondisplaced" and "open fracture" of the hamate body.
• Verify that this is the patient's first encounter for this specific injury; subsequent care will require a different encounter character.
• If the laterality (left or right wrist) is specified in the medical record, a more specific code should be selected.
