Fracture of unspecified phalanx of right thumb, sequela

This code signifies a long-term complication or late effect stemming from a fracture of an unspecified phalanx in the right thumb. It indicates that the initial injury has healed, but the patient continues to experience residual issues directly attributable to the past fracture.

Apply this code when documenting conditions such as chronic pain, stiffness, deformity, limited range of motion, or nonunion/malunion that are a direct consequence of a previously sustained right thumb phalanx fracture. This code is used after the acute phase of the fracture has passed and the patient is presenting for treatment of these persistent issues.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M25.541 for pain in right thumb).
• Ensure documentation clearly links the current condition to the past right thumb phalanx fracture.
• Do not use this code for initial or subsequent encounters for the acute fracture itself.
