Unsp fracture of third metacarpal bone, left hand, sequela

This code indicates a past fracture of the third metacarpal bone in the left hand, where the specific type of fracture (e.g., transverse, oblique, comminuted) was not documented or is unknown. The "sequela" designation signifies that this code is used to report a condition or complication that is the residual effect of an old injury, rather than an active, acute fracture.

This code is appropriate when a patient presents with a long-term complication or residual problem directly attributable to a previously sustained, unspecified fracture of the left third metacarpal. Examples include chronic pain, malunion, nonunion, or functional limitation stemming from the old injury. It should be used after the initial healing phase of the fracture has passed.

• Always ensure documentation clearly states the condition is a sequela of a previous injury, not an acute event.
• Do not use this code for an active, acute fracture; instead, select an appropriate acute fracture code.
• Consider additional codes to specify the nature of the sequela (e.g., M25.542 for chronic pain in the left hand).
