Disp fx of base of unspecified metacarpal bone, sequela

This code signifies a long-term complication or late effect resulting from a previously displaced fracture at the base of any metacarpal bone in the hand, where the specific metacarpal is not documented. It indicates that the patient is experiencing ongoing issues directly attributable to the original injury after the acute phase of healing has passed.

This code is appropriate when documenting conditions such as chronic pain, nonunion, malunion, limited range of motion, or deformity that are a direct consequence of a past displaced metacarpal base fracture. It should be used for follow-up encounters addressing these residual problems, not for the initial injury or acute treatment.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., M25.54- for chronic pain in hand).
• Ensure documentation clearly links the current condition to the previous metacarpal fracture.
• Avoid using this code for acute or subacute fracture care; it is exclusively for late effects.
