Disp fx of fourth metatarsal bone, unspecified foot, sequela

This code signifies a past fracture of the fourth metatarsal bone in an unspecified foot that was displaced and has resulted in a current long-term complication or residual effect. This could include chronic pain, malunion, nonunion, or functional impairment directly attributable to the original injury. The "sequela" designation indicates that the acute phase of the fracture has passed, and the patient is now experiencing a consequence of that prior injury.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct result of a previously sustained, displaced fourth metatarsal fracture. This is appropriate for follow-up encounters where the focus is on managing the chronic effects of the old injury, rather than the initial healing process. Examples include evaluating persistent gait abnormalities or chronic pain years after the fracture.

• Always use in conjunction with a code describing the specific sequela (e.g., M21.9 for unspecified acquired deformity, M79.67- for pain in foot and toes).
• Ensure documentation clearly links the current condition to the historical displaced fourth metatarsal fracture.
• Do not use for acute or subacute fractures; those require codes from the initial or subsequent encounter categories.
