Nondisplaced unspecified fracture of left great toe, sequela

This code describes a long-term complication or late effect stemming from a prior fracture of the left great toe (hallux) that was not displaced at the time of the original injury. The specific bone involved in the great toe fracture is not documented. This sequela could manifest as chronic pain, stiffness, deformity, or functional limitation directly attributable to the healed or healing fracture.

This code is appropriate for encounters where a patient presents with a current condition that is a direct consequence of a previously sustained, nondisplaced fracture of the left great toe. This includes follow-up visits for ongoing issues related to the old injury, such as post-traumatic arthritis, nonunion, malunion, or persistent pain after the acute phase of healing has passed. It should be used when the original fracture has healed, but its effects are still being addressed.

• Always sequence this code after the code describing the specific sequela (e.g., M20.12 for hallux rigidus, left foot).
• Ensure documentation clearly links the current condition to the past nondisplaced left great toe fracture.
• Verify that the "S" seventh character is appropriate, indicating a sequela, rather than an initial or subsequent encounter for the acute fracture.
