Fracture of unspecified phalanx of left thumb, sequela

This code indicates a healed or chronic fracture of an unspecified phalanx of the left thumb, where the patient is still experiencing residual effects or complications from the original injury. It signifies that the acute phase of the fracture has passed, but ongoing issues related to the fracture site persist.

This code is appropriate for documenting follow-up care for patients with long-term complications such as malunion, nonunion, pain, stiffness, or functional limitations directly attributable to a previously sustained left thumb phalanx fracture. It should be used when the patient is no longer in the initial healing phase but requires continued management for sequelae.

• Ensure documentation clearly links the current condition to a past left thumb phalanx fracture.
• Always use in conjunction with a code describing the specific sequela (e.g., M20.092 for malunion, M79.642 for pain in left hand).
• Verify the laterality (left thumb) and that the phalanx is unspecified if a more specific phalanx (proximal, distal) is not documented.
